Abstract:
Background: Doctors at all levels of care are directly or indirectly involved in the counselling and screening of patients with regards to prevention of cervical cancer. Despite the fact that Pap smear screening modalities have reduced the incidence of mortalities from cervical cancer some female medical doctors are indifferent when it comes to accepting this screening method.
Aim: To ascertain the attitude of female doctors towards Pap smear screening modalities at the Rivers State University Teaching Hospital (RSUTH).
Method: It was a cross-sectional study amongst female doctors randomly selected at the Rivers State University Teaching Hospital over a 1-year period. Informed consent was obtained from the subjects. The information obtained was coded and analysed using SPSS version 25.
Results: Three hundred questionnaires were distributed and 280retrieved. The mean age from the study was 31.1 years. The maximum number of children was 5. Two hundred and sixty-nine (96.1%) of the female doctors accepted pap smear, of which 94 (33.5%) had had Pap smear in the past, while 185 (66.1%) had not had Pap smear screening for cervical cancer. One hundred and forty (50%) of the female doctors preferred an alternative to pap smear.
Conclusion: This study revealed that the acceptance of pap smear for the screening of cervical cancer by female doctors at the RSUTH was 96.1%., though those that had pap smear screening for cervical cancer in the past were below average. Half (50%) of the female doctors preferred alternative to Pap smear. Effort should be made by the government and stake holders to make other screening methods for the prevention of cervical cancer especially amongst female doctors available.

Objectives : An analysis of published science about the clinical value of triage options after HPV-positive screen results.
Methods : MedLine was searched from 2001 through 2020 for relevant studies, supplemented by hand-searching of retrieved article reference lists. Eligible studies included prospective studies of women and retrospective studies of residual specimens from women that were tested using HPV genotyping tests. Outcomes were CIN2/CIN3 or CIN2 + /CIN3 + or invasive cervical cancer. The comparator was cytology as a triage for HPV-positive results.
Results : Reporting genotyping provides discrimination of both current and future CIN3 + risks. Genotyping combined with cytology improves risk discrimination for Bethesda categories NILM, ASC-US, LSIL. Improvements in referral rates may be achieved. Immunohistochemical staining with p16 and Ki67 has good evidence for triage of HPV-positive screening results. Methylation of viral HPV and host markers has fair evidence for triage of HPV-positive screening results and may be applicable to self-collected samples. Surrogate estimates of viral load may provide additional risk discrimination.
Conclusion : Based on quality-evaluated studies that met inclusion criteria, genotyping combined with cytology discriminates risk and supports risk-based clinical action steps by the principle of equal management for equal risk. Viral load could be used to augment genotyping risk discrimination. P16/Ki67 staining could be used as an adjunct to cytology or to replace cytology. Methylation tests could be utilized as an adjunct triage test with cytology, or to replace cytology as triage. Models for different management paradigms are described.
Truscreen Pvt. Ltd, Australia
Objective: The TruScreen is a real-time device differentiating cervical tissue by electrical and optical signals, which might be an option for regions that are difficult to build laboratory-based screening system for cervical cancer. To assess the clinical performance of TruScreen in detecting high-grade cervical lesions in Chinese women.
Methods: During May 2017 and August 2018, women visited the gynaecology clinics at 5 top hospitals for cervical cancer screening or for colposcopy were invited to participate. The voluntary women all underwent TruScreen examination, liquid-based cytology and hrHPV DNA testing, and colposcopy. Biopsy was performed when cytology was LSIL or worse, or the findings of TruScreen or colposcopy were positive. Histopathology diagnosis was the golden standard.
Results: 1,022 women were included for data analysis. 62.4% of the women were cytological ASC-US + , 91.3% were high-risk HPV positive. TruScreen test was abnormal in 41.5% women. Among the 1022 women, 152 women were diagnosed with CIN2 and 99 were diagnosed with CIN3 + lesions. The CIN2 + and CIN3 + yields were much lower for positive HPV with negative TruScreen, compared with NILM cytology (CIN2 + : 4.4% vs.13.4%; CIN3 + : 1.0% vs.4.0%, P < 0.05). The sensitivity and specificity for HPV testing and TruScreen co-testing for CIN2 + and CIN3 + was 99.6% and 9.4%, 100.0% and 7.9%, respectively. The strategies of triaging HPV-positive women with TruScreen in detecting CIN2 + or CIN3 + showed high sensitivities as 89.3% or 91.9%.
Conclusion: TruScreen test as a simple and rapid real-time method for early diagnosis of cervical cancer and precancerous lesions is very promising. The combination of hrHPV DNA testing and TruScreen, or the strategies of triaging HPV-positive women with TruScreen, also demonstrated a better accuracy than that of hrHPV and cytology co-testing.
Dalrada Health, Bangalore, India
Objectives : To evaluate if combined screening with Pap smear and VIA had any added benefit in a tertiary care setting.
Methods : This is a cross-sectional study involving a total of 100 cases who would be recruited in the outpatient department when presenting with various gynecological complaints and fulfilling the study inclusion criteria. An experienced gynecologist conducted the procedure. Brief clinical history followed by visual inspection with acetic acid using a disposable kit and Pap smear test were done on all cases for comparison of results. Biopsy was done if VIA was positive or Pap smear showed any abnormality.
Results : VIA was negative most of the time, approximately 96% of cases. And this result was concordant with Pap test showing inflammatory smears with no intraepithelial lesions and biopsy being negative. About 30% of cases had discharge clinically consistent with candidial infection; however, only few pap smears showed budding yeast.
Conclusion : Involving a specialist might reduce the false positivity of VIA. Not all erosive unhealthy-looking cervix which bleeds on touch was found VIA/PAP positive. PAP might not pick up all candidial infections. Combining both tests will reduce the number of visits to the hospital as a VIA-positive case can come with biopsy report and PAP report at the same time. The sensitivity and specificity of both tests shall be updated on completion of the study.

Objectives : The cancer of uterine cervix is still the most prevalent cancer in rural India. Many group checkups and camps are regularly arranged in rural areas for early diagnosis, but still the sensitivity rate is very low for conventional pap smears. The most likely reason for this is the unsatisfactory rate due to widespread use of conventional Ayres spatula alone.
Methods : A novel spatula is devised to solve this problem keeping the cervical anatomy into consideration. The advantages of this new spatula are- No need for separate endocervical brush to take endocervical sample Spatula is wooden and gives good scrapes without trauma from all areas of cervix Customizable to small-, large- or irregular-sized cervix sizes It is economical & reusable after high-level disinfection

Objectives : To assess diagnostic test characteristics of FNa compared to the definitive histopathological diagnosis of pre-malignant /malignant lesions of the cervix. To describe the correlation of FNa with VIA, VILI and colposcopy.
Methods : Seventy patients, with abnormal screening tests /symptoms, who were referred for colposcopy, were enrolled. In addition to the usual acetowhite and Lugol’s iodine used in the colposcopy procedure, FNa was also used. Abnormal areas look fluorescent green when seen under UV light in a dark room. Biopsies were taken from the abnormal areas highlighted after staining and the histopathology report was the gold standard. For analysis, disease threshold for Biopsy was “CIN2 + ”. For the index tests, positive result for acetowhitening taken as “distinct staining”; for lugol’s iodine “distinct yellow” and for Swede score “score > 5”, and for FNa “distinct fluorescence”.
Results : The sensitivity of FNa staining was 0.52, lower than both acetowhite and lugol staining. The specificity was higher at 0.867. Accuracy was 0.743.
The prevalence of CIN2 + was 35.7. The PPV was 0.684 and, NPV was 0.765. Positive likelihood ratio was 3.9, and negative likelihood ratio was 0.55.
The kappa coefficient for acetowhite and FNa was 0.538; and for Lugol’s iodine and FNa was 0.54; both suggesting moderate agreement.
Conclusions : The sensitivity of fluorescent sodium was lower, but specificity was quite good with an accuracy of 74%. FNa is low cost and easy to perform as well. It appears to have enough potential to deserve further study.
Gene Path Diagnostics India Pvt Ltd, India
Objectives : The detection of human papillomavirus (HPV) DNA from urine can potentially increase the coverage of cervical cancer screening in women as it circumvents the need for cervical sampling. Urine, however, contains nucleases that degrade HPV DNA. Therefore, we aimed to develop a buffer that can preserve DNA in urine, thereby facilitating accurate and non-invasive detection of HPV.
Methods : HeLa cells were used to perform proof-of-principle experiments. DNA was extracted from urine spiked with a known number of HeLa cells with or without our buffer or commercially available urine preservation buffers stored at ambient temperature at different time points; appropriate controls were set up. Quantitative polymerase chain reactions (qPCRs) targeting a human housekeeping gene (RNaseP) and the L1 region of HPV were performed on the extracted DNA.
Results: The developed urine buffer protected DNA from degradation more effectively than did the commercial buffers. Additionally, the buffer enhanced DNA extraction even at the 0-day time-point. DNA in the control (urine + HeLa cells) degraded rapidly after day 3, whereas the tube containing urine + HeLa cells + GPDx urine buffer showed a stable level of RNaseP over the 7 days.
Conclusions: The developed DNA preservation buffer offers a viable and cost-effective method for the storage and transport of urine at ambient temperatures. This is especially helpful in a developing country like India where there is a social stigma attached to cervical sampling. Noninvasive samples like urine along with appropriate HPV testing may help overcome logistical and social issues for cervical cancer screening programs.

Cervical cancer is one of its type of cancer where there is a long phase of pre-invasive stage and an easy approach to screening. Inspite of these facts, we have yet to find out a test which can be easily done, widely available with high sensitivity and cheap.
Till now Paps, VIA & VILLI are being used to detect and look for changes associated with pre-malignant leisons of cervix. Because of cost requirement, trained staff and poor sensitivity, we are missing out on opportunities to screen women more so in rural areas.
This presentation is to bring to your notice an Artificial Intelligence System being developed that can outperform human experts in identifying Cervical Pre-Cancer called automated visual evaluation.
All India Institute of Medical Sciences, New Delhi, India
Objectives : Screening programs in low-middle-income countries are not able to reach the target population. Portable colposcopes can decrease costs-cum-referral rates. To compare the quality of images captured with a transvaginal colposcope (TVC) by a field worker (FW), and to assess the image adequacy for determination of colposcopic diagnosis and management decisions.
Methods: Women aged 21–65 years with abnormal screening report/cervical symptoms were enrolled. FW reported visual inspection with acetic acid (VIA) test results, captured images with TVC. The physician performed cervical assessment with colposcopy by both TVC and Digital video colposcope, calculated Swede scores, and obtained biopsy from all lesions. Images captured by the FW were assessed by colposcopist for adequacy for decision-making and management. Next, the ability of the FW to identify patients for referral was assessed, agreement between the Swede score from both sets of images was calculated.
Results : Among 125 subjects, 96 (76.8%) were VIA positive and 12 (9.6%) had CIN2 + lesions. Of the images captured by the FW 122 (97.6%) were adequate for interpretation. Swede score calculated from the images captured by both FW and physician showed perfect agreement (K = 1.0). At Swede score cut-off of > 5 to detect CIN2 + , images collected by both had sensitivity, specificity, PPV and NPV of 83.3%, 73.3%, 30.3% and 97.4%, respectively. Images were reviewed by FW and colposcopist. FW and colposcopist estimated that 98 (78.4%) and 34 (27.2%) subjects need referral.
Conclusions: TVC can be used by FW to capture cervical images which can be reviewed by colposcopist to reduce referral rates.

Objectives: To evaluate the role of p16Ink4a immunostaining for detection of CIN2 + in women who had a positive screening test using visual inspection with acetic acid (VIA).
Methods : Opportunistic screening of women (30-50 years) coming to gynecology clinic by VIA was performed; the screen positive women were included in the study which had the IRB approval. A cytology slide for p16 Ink4a immunostaining and biopsy were then performed sequentially. The sensitivity, specificity, PPV & NPV of p16 Ink4a immunocytochemistry was evaluated with histopathology as the gold standard.
Results: p16 Ink4a positivity showed a linear correlation with increasing grade of CIN. p16 Ink4a positivity was seen in 6% of CIN 1, 80% of CIN 2, 100% of CIN 3 and SCC. The sensitivity and specificity of p16 Ink4a immunocytochemistry for detecting CIN 2 or more was 87.5% (95%CI 61.65–98.45) and 97.06% (95%CI 84.67–99.93).
Conclusion: With high sensitivity and specificity, p16Ink4a immunocytochemistry could be a viable option for triaging VIA positive women.

Objectives: To measure the agreement level between direct and indirect interpretation of VIA test using digital image taken with smartphone camera for cervical cancer screening.
Methods: 208 women aged 20–60 years who attended the cervical cancer screening program held by Jogjakarta Health Department in Sanden Primary Health Center, Indonesia, agreed to participate in this study. The screening was done by applying acetic acid to the cervix (VIA). After application, about 1–2 min (s), the absence or appearance of acetowhite lesion was observed. Images of the cervix then taken using 8 megapixels and 12 megapixels smartphone cameras. Direct interpretation of VIA test was done at the screening location, while indirect interpretation was done away from the screening location by 3 experienced obstetrics and gyncecology doctors through the digital images taken with the smartphone cameras. Agreement level between direct and indirect VIA interpretation was measured. Furthermore, agreement level between 8 and 12 megapixels camera and agreement among raters who did the indirect VIA interpretation was also measured.
Results: Agreement levels between direct and indirect VIA interpretation are 0.303 (95%CI: 0.063–0.542) and 0.471 (95%CI: 0.193–0.748) for 8 megapixels and 12 megapixels camera consecutively. Agreement level between 8 megapixels camera and 12 megapixels camera is 0.580 (95%CI: 0.336–0.824). The inter-rater agreement levels are 0.408 (95%CI: 0.243–0.571) and 0.293 (95%CI: 0.070–0.502) for 8 megapixels and 12 megapixels camera consecutively.
Conclusions: Smartphone camera is may increase the efficiency of VIA test for cervical cancer screening.
Peking University People’s Hospital, China
Objectives: To evaluate the feasibility of vaginal self-sampling for cervical cancer screening on Internet-based, and the triage value of high-risk HPV genotyping.
Methods: Totally 10,056 women aged 30 ~ 59 years with self-sampling were recruited for cervical cancer screening between September 2018 and May 2019 in 8 provinces, and 984 had histological diagnosis. The 14-HPV testing was performed by real-time PCR assay. Women registered online ( http://47.106.227.241/ ) and signed online informed consent. Self-sampling by themselves from the vagina. The feeling and acceptability of self-sampling were investigated after sampling.
Results: Of the 10,056 attenders, the success rate of self-sampling was 99.86%. HPV infection rate is 15.56%(1565/10,056) among 8 provinces. The positive proportion of the top 5 HPV genotypes were HPV52, − 16, − 58, − 39, − 56. Among the 14 hrHPV involving HSIL + cases, HPV16, − 33, − 52, − 58 were most likely to develop HSIL + . If HPV16/18 combined with HPV33, detection rate of HSIL + increased by 52.3%, colposcopy referral only increased by 4.2%. In addition, 92.3% women feel that it is easy to master self-sampling, 86.4% have no discomfort, and 60.8% attenders are more likely to choose self-sampling for cervical cancer in the future.
Conclusions: The self-sampling cervical cancer screening on internet-based is a simple, convenient and very promising screening model with a more higher acceptability of self-sampling in the future in China. Extensive genotyping could identify some more high-risk genotypes for detecting HSIL + , apart from HPV 16/18, HPV33 showed a higher prevalence in detection of HSIL + lesions, combine with 3 types may be as a triage way.
Department of Obstetrics and Gynecology, Al-Wakra Hospital, Qatar
Objective: Comparative analysis of diagnostic accuracy and cost-effectiveness of conventional and novel methods of cancer cervix screening.
Design: A literature review.
Method: An internet-based literature search for all the available methods of cancer cervix screening in the PubMed/MEDLINE, Scopus, Cochrane, and EMBASE databases. Studies published between 1990–2020 were evaluated. 52 studies were included. Relevance screening, data extraction, risk of bias analysis, and quality assessments were conducted. The sensitivity and specificity of screening methods and their cost-effectiveness were evaluated.
Results: In comparison to conventional methods (pap smear, HPV DNA, VIA, VILI), Care HPV assays and Hybrid Capture 2 test have higher sensitivity 91.1% and specificity 83.7%. They provide logistical and economic advantages but lack sensitivity as compared to HPV DNA. Detection of TERC predicted progression of CIN1/2 to CIN3 after a follow-up of two months to three years with 100% sensitivity and 70% specificity. Cost and need for technical skills are the limitations. The sensitivity and specificity of p16/Ki-67 dual-staining for CIN2 + were 74.9%-90.9% and 72.1%-95.2%, respectively. This method is useful in the unnecessary follow-up of HPV positive and is cost-effective for HSIL. Optical methods of screening are emerging as non-invasive tests with high sensitivity 90–98% but low specificity for HSIL lesions. They may be considered as the first-line screening and triage during the same medical visit, thus, significantly reducing the cost.
Conclusion: The novel methods are cost-effective in women with HSIL and those who are HPV positive with better sensitivity as compared to the conventional methods.

It should not come as a surprise that technology, despite the dramatic way in which it has altered our ability to image the body, measure and monitor its molecular structure, can also fail just as badly as humans fail. The Fourth Industrial Age cantered on artificial intelligence (AI), robotics, and Big Data, ushers in a profound transition that can already be seen in how we live and function, and maybe even in how we think about ourselves as humans. It has a lot of potential not only to support, but also to hurt, by exacerbating the deep divide that already exists between those who have a lot and those who have less with each passing year. It should not come as a surprise that technology, despite the dramatic way in which it has altered our ability to image the body, measure and monitor its molecular structure, can also fail just as badly as humans fail.
ARTIFICIAL INTELLIGENCE in medicine is expected to provide integrated, panoramic views of individuals' medical data to avoid mistakes; to aid in treatment; and treatment decisions and interpretations; and tests; and to minimize misdiagnoses and false-positive results. Useful[preoperative data]intelligence from colposcopy for preoperative data, the population has been segmented into three categories: Extreme Dysplasia, Cervical Intraepithelial Carcinoma (CIC), and Invasive Cervical Cancer (IC). Methods for applying deep learning to colposcopy image classification may be preliminary, but it suggests that clinicians and researchers who are not specialists in artificial intelligence or machine learning can make use of deep learning.
AI will be used as a promising tool in gynaecology and obstetrics to solve a number of longstanding challenges; and AI could still serve as a means to increase knowledge and help clinicians to make decisions in a range of fields in obstetrics and gynaecology.
Saveetha Medical College, Mylapore, Chennai, India
Objective: Fluorescence spectroscopy measures fluorophores which might change according to pre-neoplastic and neoplastic tissues. The aim was to assess performance of fluorescence spectroscopy in the diagnosis of different grade of squamous intraepithelial cervical lesions (SIL). The objectives were to compare fluorescence spectroscopy findings with colposcopic findings, Papanicolaou smear and histopathology report.
Method: Prospective observational study was conducted after ethical clearance and informed consent . 65 women between 25 to 60 years attending the outpatient clinic of Saveetha Medical College Gynaecology Department between June2019to Dec 2019 with discharge per vaginum, low backache, irregular bleeding and post-coital bleeding were included. After gynaecological workup, Pap smear and colposcopy and. cervical biopsy were done. Fresh tissue was sent for Fluorescence spectroscopy. Tissue was excited using a filtered short-arc xenon lamp at 375–460 nm and a power output of 200 mW. Spectral measurements were performed. Same biopsy tissue was confirmed by the final histopathological diagnosis. Changes in the fluorescence properties of cervical squamous epithelium that are associated with the development of neoplastic disease were assessed.
Results: At 380 nm excitation of the tissue, high SILs can be differentiated from low SILs with sensitivity of 79% specificity 74%, PPV 81%, respectively. At 460 nm excitation, low SILs can be differentiated from normal with an average sensitivity, specificity and positive predictive value of 82%, 78% and 74%, respectively, which is similar to that of colposcopy. There was 100% correlation of fluoroscopy report with HPE.
Conclusion: Spectroscopic methods are potentially a reliable, fast method and can be an alternative to other screening methods. Spectroscopic signatures can be used for diagnosing SILs with a handy device.

Objective: The objective of the study was to quantify and compare the levels of methylated PAX1 gene in normal, cervical intraepithelial neoplasia2/3 and invasive cancer.
Design: Observational analytical study.
Method : In this experimental study 201 screen positive women (VIA, VILI and Pap test) underwent colposcopy and 94 women with Swede score of 5 or more were biopsied. On histopathology 55 had chronic cervicitis or squamous metaplasia, 13 had diagnosis of CIN 1, 20 had CIN 2/3 and 6 had invasive squamous cell carcinoma. 14 women with obvious growth were also recruited. Cervical scrapes taken, were sent for PAX 1 methylation level. 60 women were recruited to the study and allocated into three groups, i.e. Benign cervices (Group1; n = 20), CIN 2/3 (Group 2; n = 20) and invasive cervical carcinoma (Group; n = 20).
Results : The mean PAX1 methylation levels in benign lesions, CIN 2/3 and invasive cancer were 9.58% (SD ± 2.37%), 18.21% (SD ± 2.67%) and 24.34% (SD ± 4.09%), respectively, with p value of < 0.001. The ROC curve for analysis of PAX 1 methylation percentage in cancer versus CIN 2/3 showed the best cut-off point was 21.8% (sensitivity = 76.67% and specificity = 100%. (P < 0.001)), while analysis in CIN 2/3 versus normal showed the best cut-off point as 12.38% ( sensitivity and specificity = 100%).
Conclusions : PAX 1 methylation levels have a promising role in identifying CIN2 and worse lesions. Addition of DNA methylation testing in screening programs will need validation with larger multi-centric trials.
Department of Obstetrics and Gynaecology, Deenanath Mangeshkar Hospital and Research Centre, Erandwane, Pune, India
Objective: Feasibility assessment of Smart Scope® (SS) coupled with Artificial intelligence-based assessment (AI-A) as a potential cervical cancer screening method.
Design: Observational, single arm study conducted at Deenanath Mangeshkar Hospital, Pune, India.
Method: Study was conducted in two phases; 509 in first and 246 women in second phase were enrolled. In the first phase, naked eye visual screening (NE), cytology and SS aided visual assessment (SS-VA) of cervix for detection of precancer and cancer were compared considering histopathology as gold standard. In the second pilot phase, a set of cervical images captured by SS was assessed (blinded) by expert health provider as well as by AI-A and were compared with histopathology as gold standard. The AI assessed cervical images in 3 categories; Green (normal), Amber (benign) and Red (precancer and cancer).
Result: In first phase, SS-VA demonstrated 100% sensitivity and NPV. In second phase, SS-VA by an expert could detect all confirmed precancer cases but over-estimated the lesions in 8 women. AI-A underestimated one precancerous lesion as benign but reduced the overestimation of precancerous cases.
Conclusion: SS-VA has great potential as a primary screening test in a low-resource setting due to its better sensitivity and NPV. The AI-based assessment for detection of cervical abnormalities may help the health providers for immediate risk classification of cervical abnormalities and reduce burden on tertiary centers for colposcopy. This simple single visit test if used widely may help to increase the participation of women in screening program.
Department of Obstetrics and Gynaecology, JIPMER, India
Objectives : To evaluate the efficacy of Swede and Reid Colposcopic Indices to predict high-grade lesion of cervix and to assess the strength of correlation between these two Indices.
Methods : In this retrospective study, 160 women aged 30 to 69 years with abnormal screening results were included. In all women who underwent colposcopy, both Reid Colposcopic index and Swede index were routinely calculated in our clinic and biopsy taken from all abnormal areas. Performances of both the scores were calculated and compared using our colposcopy register data.
Results : A total of 49 (30.6%) CIN 2 + lesions were detected. Reid Colposcopic index at a cutoff of 5 had sensitivity, specificity, positive predictive value, and negative predictive value for detecting CIN2 + lesions of 95.9%, 93.7%, 87%, and 98.1%, respectively. Using Swede index at a cutoff of 8, sensitivity, specificity, positive predictive value, and negative predictive value were 44.9%, 100%, 100%, and 80.43%, and with a cutoff of 5, these were 100%, 85.6%, 75.38%, and 100%, respectively. The correlation coefficient (R2) was 0.91 by Spearman rank correlation coefficient.
Conclusion : Swede index has a good correlation with Reid Colposcopic index. Swede score of 8 or more has 100% specificity and can be used for screening-and-treating in the same setting to decrease the overtreatment rate.
Department of Gynaecologic Oncology, Christian Medical College, Vellore, India
Objectives : To audit the performance of colposcopy with respect to indications, results and its correlation with post-procedural biopsies using the NHS Cervical Screening Programme Colposcopy and Programme guidelines in collaboration with the British Society for Colposcopy and Cervical Pathology.
Methods : We audited data of colposcopies done for abnormal cytology smears from November 2017–June 2018. Indications for the colposcopy, findings, biopsy results, follow-up procedures done were looked into. These were then analysed according to the International federation for colposcopy/ NHS SPCP guidelines and checked for the fulfilment of criteria.
Results : A total of 14,332 Pap smears were done at this tertiary hospital during this period. Colposcopies were done for 150 of these patients. Of these, 67 cases on whom colposcopies done for the high-risk HPV positive and Pap smear abnormality ASCUS and above were audited. The audit revealed compliance in 7 out of 8 criteria except for in the adequacy of the reporting of colposcopy of the transformation zone not achieved in 2.5%. The correlation for the low-grade score < 6 to low-grade biopsies ( 6 to higher grade lesions was good with kappa coefficient of 0.572 and p value of < 0.000.
Conclusions : Audit of colposcopy performance using the NHSCSP guidelines revealed that compliance to guidelines was good. Correlation of colposcopy findings with the diagnostic biopsy was good. Supervised training is essential and can lead to quality improvement with fulfilment of all standards.
Shree Sayaji General (SSG) Hospital, Vadodara, India
Objectives : To evaluate colposcopic Swede Score in the detection of Cervical Intra-epithelial Neoplasia.
Methods : An observational study where 50 Women coming to gynecology OPD of our hospital with complaints of abnormal uterine bleeding, chronic pelvic pain, vaginal discharge, abnormal Pap smear, acetowhite lesion on application of acetic acid (VIA positive), HPV positive, were examined using digital video colposcope colpro 222. Colposcopic guided punch biopsies were taken from abnormal areas and sent for HPE examination. The swede scores were compared against the histologic diagnosis. Data and images were stored using the Colpro software. Diagnostic accuracy of swede score in the detection of cervical neoplasia would be calculated using appropriate tests.
Results: Agreement between colposcopic swede score and histopathology. Biopsy detected CIN-1 in 17 (34%) patients CIN2 + (CIN 2, CIN 3) in 8 (16%) patients, 2 (0.04%) women were found to have carcinoma in situ. 17 women were positive for HPV, 3 women had HPV 16, 14 women had other high-risk HPV, which are independent risk factors for CIN.
Conclusion: Colposcopy by Swede score could offer a more accurate screening and selection for immediate treatment of cervical lesions in low-resource settings.

Methods: Of Total 1200 Women who were Screened at SEE & TREAT Colposcopy Clinic; 97 Women diagnosed with varoius grades of CIN Lesions were treated with LEEP. All treated Women were followed up with colposcopy at 6 months and 12 months.
Results: At 6 months,10 women lost to follow-up. At 12 month, we lost follow-up of 30 women. Healing of cervix was remarkable with no appearance of CIN lesions in all women we followed up at 6 & 12 months complications during LEEP and during follow-up if any noted. All LEEP Specimens were sent for HPE and correlation with colposcopic findings done.
Conclusions : (1) Colposcopy can be used by trained Gynaecologists for primary screening of women for cervical cancer (2) LEEP can Safely be done at SEE & TREAT Colposcopy Clinic as a OPD Procedure. (3) LEEP is an effective treatment modality for all grades of CIN. (4) See with colposcope (as a primary screening test for detection of cervical precancerous lesion where Lab. facilities for Cytology are not up to the mark and HPV DNA tests are either lacking or costly) & treat all CIN with LEEP as OPD procedure (where compliance of women for follow-up is doubtful), can be a good strategy to reduce the incidence of cancer cervix.

Objectives: In India, cervical cancer is the second most common cancer in women (aged 15–44 years) after breast cancer accounting for almost 14% of all female cancer cases. Objectives were to correlate the findings of Pap smear with colposcopy and to assess the utility of colposcopy in detecting the premalignant and malignant lesions of cervix.
Methods: This was a prospective observational study of 150 symptomatic women attending the Gynecology OPD of Indira Gandhi Institute of Medical Sciences, Patna from July 2019 to June 2020. Evaluation of all symptomatic women done with Pap smear, colposcopy and biopsy in selected cases.
Results: Commonest complaint was white discharge per vaginum in 50% followed by pelvic pain in 20% women. 9% women had abnormal pap smear findings with 2.6% of women had ASCUS, 0% had ASC-H, 3.3% had LSIL and 3.3% had HSIL,68% had inflammatory and 22% with normal smear. 30.6% had abnormal colposcopy with maximum, and 15.3% women had acetowhite lesions. Sensitivity of pap smear was 50%, while sensitivity of colposcopy was 83.3%.
Conclusions: Pap smear had poor sensitivity as compared to colposcopy. Hence simultaneous use of colposcopy has shown to increase in the rate of carcinoma cervix detection in symptomatic women.
Northwell Phelps Hospital, United States
Objectives: According to ASCCP guidelines, in women above 30 years with cytology negative, human papillomavirus (HPV) positive, it is acceptable to either repeat co-testing in 1 year or perform colposcopy for further evaluation. This choice of recommending colposcopy or follow-up co-testing is determined by the provider. Hispanic women have the highest incidence of cervical cancer compared to other races and there has been minimal research on the benefits of performing a colposcopy in a higher risk population to evaluate for grade 2 or higher cervical intraepithelial neoplasia.
Methods: Retrospective study included 600 Hispanic women over 30 years with negative intraepithelial lesion or malignancy, positive high-risk HPV across six different Open Door Family Medical Centers from October 2014 to January 2019. These women who tested NILM, positive high-risk HPV were recommended to receive a colposcopy or follow-up in 1 year for co-testing. These results were then analyzed to determine the incidence of grade 2 or higher cervical intraepithelial neoplasia.
Results: Among women with NILM/ + HRHPV, 235 (39%) had colposcopy. Of those who received a colposcopy, 82% had benign pathology and < 3% had grade 2 or higher CIN. At subsequent screening exams, 29% of women had negative cytology/negative HPV.
Conclusion: Colposcopy after a NILM/ + HR HPV screening result did not lead to earlier detection of grade 2 or 3 cervical intraepithelial neoplasia. This result indicates that women of higher-risk population, NILM/ + HRHPV, may benefit from annual co-testing and if any cytologic changes present, consider follow-up with colposcopy.
Chittaranjan National Cancer Institute, Kolkata, India
Objectives: Colposcopy is a subjective method of diagnosing cervical neoplasias. Earlier studies have evaluated correlation between colposcopy and histopathology in settings where colposcopy was done on women referred for abnormal cytology report. We aimed to determine the agreement between colposcopy and histology diagnosis when colposcopy is performed for Hybrid Capture 2 (HC 2) positive women.
Methods: Women between 30 to 60 years were screened for cervical cancer by HC2 in a community-based demonstration program. The screen positive women had colposcopy. Cervical punch biopsies were obtained from all the women. Both colposcopy and histology diagnosis were categorised as normal, HPV changes, LSIL, HSIL and cancer. Agreement was calculated by weighted kappa. Study had Institute Ethics Committee approval.
Results: A total of 689 women had colposcopy due to HC 2-positive results. On histology of 634 samples, there were 79 cases of LSIL, 30 cases of HSIL and 5 cases of cancer in the total cohort. Rest of the women were normal or had HPV changes. There was agreement in 78.65% of the observations. The weighted Kappa value of 0.275 (95% C.I. 0.194 to 0.356 indicates fair strength of agreement.
Conclusion: When colposcopy is performed on women referred due to positive HC 2, the agreement is fair between colposcopy and histology diagnosis. The study is ongoing and updated results will be presented.

Objectives: 1. To find correlation between Reid’s Colposcopic Index (RCI) and Swede Score for predicting cervical lesions 2. To find accuracy of prediction of RCI score and Swede Score with Histopathology of cervical lesions.
Methods: A cross-sectional study of 100 patients with cervical lesions, aged 30–60 years, underwent colposcopy. RCI and Swede score were determined and colposcopy-directed biopsy from abnormal areas was done, and in case no such areas were delineated, then four-quadrant biopsy was taken from cervix and sent for histopathological examination (HPE).
Results: 39% of the patients were in the age group of 30–40 years. RCI score with cut off value ≥ 5 with respect to HPE showed maximum sensitivity 88.2%, specificity 85.5%, NPV 97.3% (p < 0.001) for SCC and for CIN III sensitivity 82%, specificity 80%, NPV 97.3% (p < 0.001). Swede Score cut off value ≥ 8 with respect to HPE showed maximum sensitivity 100%, specificity 86.7%, PPV 60.7%, NPV 100% (p < 0.001) for SCC and for CIN III sensitivity 63.6%, specificity 76.4%, NPV 94.4% (p 0.02). Good correlation was found between the Reid’s score and Swede score; Spearman’s correlation coefficient r = 0.804; p < 0.001; r2 = 0.64.
Conclusion : RCI core ≥ 5 or Swede score ≥ 8 can be used for performing direct excisional procedure as a “see and treat” method.

To find correlation in cervical cytology, and colposcopy in diagnosing premalignant lesions of cervix
To find correlation in colposcopy and histopathology in detection of premalignant lesion of cervix
Methods : The study is a prospective observational study planned for 2 years; interim results obtained over a period of 1 year are discussed. The study is being conducted at Department of Obstetrics & Gynecology at AIIMS Jodhpur.
Inclusion criteria: screen positive women undergoing colposcopy and biopsy. Age between 21–70 years.
Exclusion criteria: Pregnant women, women who did not have colposcopy or cervical biopsy.
These cases were analysed and sensitivity and specificity in detecting premalignant lesion was calculated.
Results : Good correlation was observed between colposcopy and histopathology with a sensitivity of 82% and specificity of 98%.
Cytology did not correlate well with colposcopy [specificity of 58%] and histopathology [specificity of 65%].
Conclusion : Cervical cytology did not co-related well with colposcopy and histopathology, while good correlation was observed between colposcopy and histopathology for detecting premalignant lesions of cervix.
Department of Obstetrics and Gynaecology, VMMC and Safdarjung Hospital, Delhi, India
Objectives: To analyse correlation between Colposcopy and Papanicolau smear in cervical Cancer screening in patients with unhealthy cervix.
Methods : A retrospective analysis was done at GTB Hospital, Delhi, India from January 2019 to December 2019 on 120 women with unhealthy cervix. Patients with unhealthy cervix on naked eye examination were analysed who underwent Pap smear followed by colposcopy and colposcopy-directed biopsy. Papanicolau smear evaluation of unhealthy cervix is routinely done followed by Colposcopic evaluation. Green filter, Acetic acid, Lugols Iodine are used to assess the cervix. Any abnormality is identified, lesion labelled, colposcope-directed biopsy of cervix is taken and Histopathology of biopsy is done.
Results: Analysis of 120 women who underwent colposcopy following a clinical examination and Pap smear was done. Of the 120 patients, 40% were in the age group 31–50 years and 20% were in the age group of 51–65 years. 80% of patients were more than Para-2. Cervical biopsy were taken in 34% of cases in whom either Pap smear or colposcopy or both were abnormal and their correlation was studied. 15% patients with normal PAPs had CIN-I and none had CIN-III on Histopathological examination. In 2% cases with HSIL had CIN-III and 8% with LSIL had CIN-II.
Conclusions: Cervical cancer is the commonest malignancy in India and third most common cancer in the world. Both Pap smear and colposcopy can be used reliably to screen women having abnormal symptoms for diagnosing pre-malignant lesions. Histopathology of suspected lesion remains gold-standard for final diagnosis of pre-cancerous lesions.
IGIMS, Patna, India
Objectives: Suspicious-looking cervix includes all cervical lesions having potential for cervical cancer. Mostly it includes benign and inflammatory conditions of cervix like ectropian, polyp, leukoplakia and nabothian cyst and patient may be asymptomatic or have complaints of abnormal vaginal discharge and post-coital bleeding. To evaluate the colposcopic outcome of women with clinically suspicious cervix.
Methods: A prospective cohort study of women with clinically suspicious cervix referred for colposcopy was conducted. Such patients underwent screening by pap smear & colposcopy along with optional HPV testing. Relevant data were collected and analyzed using appropriate statistical method.
Results : A total of 313 patients were included in the study. Amongst women (240/313) with negative primary screening only 6 out of 147 who underwent biopsy were reported CIN I/ CIN II on histology and rest had chronic cervicitis. CIN III & invasive lesions were found in women with abnormal pap and positive for co-testing report. Positive predictive value of colposcopy for detecting CIN & invasive one was higher but had poor specificity and was observer dependent.
Conclusion: Clinically suspicious cervix should be triaged by primary screening method, either cytology or co-testing. Colposcopy should be suggested for women with positive primary screening test.
Nalupurakkal, Narayana Nagar, India
Objectives: To study the applicability of Office colposcopy as a part of standard gynaecological examination in Kerala.
Methods : This Colposcopic study was conducted in 1000 women between 30 to 60yrs. They came to my outpatient clinic at Vatakara, Kozhikode district, Kerala, with various gynecological complaints. Study duration was 5 years from 1/6/2011. The importance of cervical screening was discussed with all married gynaecological patients. 1000 subjects agreed for colposcopy examination. Office colposcopy was done using ASCON AC 3 with a fixed magnification of 6x.
Results : Colposcopy study was adequate in 897 (89.7%) subjects and inadequate in 105 (10.5%). Normal colposcopic findings were seen in 254 women (25.4%). Colposcopic diagnoses of precancerous lesions were made in 209 (20.9%) subjects. Out of this LSIL was diagnosed in 193 (19.3%) and HSIL was seen in 16 (1.6%). Invasive carcinoma was diagnosed in 5 (0.5%). 34.4% (344) of subjects had benign conditions of cervix {c/c Cervicitis 187 (18.7%), Severe ectropion 96 (9.6%), cervical polyps 61 (6.1%) } . The incidence of infection was 18.8% (188) candida infection 10.3% (103), trichomoniasis 6.1%(61), mixed bacterial infection 24 (2.4%).
Conclusions: In a state like Kerala where people are educated and health conscious, unfortunately, we have no organized screening program for cervical cancer. If office Colposcopy is accepted as a part of standard gynaecological examination, every gynaecologist can diagnose cervical pathology easily and can give necessary treatment in the same sitting. Normal Colposcopy findings, confidently predicts cancer-free cervix for the next 5–10yrs.

Objectives: To compare the histological features, recurrence rate and survival, between different histological types, in patients who underwent radical hysterectomy (RH) for early cervical cancer.
Design: Retrospective study.
Methods: This study compared the outcome of patients with squamous cell carcinoma (SCC) and adenocarcinoma cervix (AC) who underwent RH at our institute from 1 st January 2007 to 31 st December 2018. Patient details were collected from medical records. Kaplan Meir survival curves were generated to assess disease-free survival (DFS) and overall survival (OS).
Results: A total of 136 patients with early cervical cancer underwent RH during this time period. 95 patients (69.8%) had SCC and 41 patients (30.1%) had AC. The baseline patient profile, preoperative FIGO stage were comparable between the two groups. The number of patients having tumors size greater than 4 cm was higher in case of AC compared to SCC (19.5% vs 2.2%, p value 0.002). The rate of parametrial involvement and nodal metastasis were comparable. Significantly higher percentage of patients with AC received adjuvant therapy compared to SCC (75.6% vs 53.9%, p value 0.021). The median follow-up period was 74 months. The 3 year DFS was 92.2% and 95.5% (p value 0.504) for AC and SCC, respectively, and the 3 year OS was 97% and 100% (p value 0.194).
Conclusions: Patients with adenocarcinoma tend to have a larger tumor and are more likely to receive adjuvant therapy. The histological subtype does not have an impact on survival in patients with early cervical cancer undergoing RH.

Objectives: Due to local myths or poor health services millions of women worldwide never undergo cervical cancer survey and hundreds of thousands die prematurely without ever knowing why they were ill. Cervical cancer in India is second most frequent cancer among women, burden is higher due to lack of screening and health services. Study was included to evaluate if parallel testing with PAP and Colposcopy can maximize the sensitivity for screening of CIN and Cancer Cervix. Aim of this was to screen symptomatic women irrespective of the development of premalignant and malignant lesion of cervix.
Methods: This study was conducted in 200 symptomatic women meeting with inclusion criteria, attending OPD of Obstetrics and Gynaecology department attached to Dr S N Medical College, Jodhpur. After taking consent and history women were subjected to PAP and Colposcopy followed by Biopsy for selected cases.
Results: Out of 200 symptomatic women commonest complaint was white discharge. 3% Women had inflammatory findings on Pap smear, 4% had ASCUS, 0.5% ASC-H 3% HSCL, 0.5% HSLL, 21% Normal Colposcopy, 38.5% Abnormal Colposcopy, 28.5% miscellaneous finding and 12% had Indecisive.
Conclusions: Cervical cancer is a premalignant disease and has a long pre-invasive phase. With the help of screening methods like pap smear and colposcopy, cervical lesions can be diagnosed early before reaching in invasive stage in a single visit approach.
S N Medical College and Umaid Hospital Jodhpur, Rajasthan, India
Introduction: In India, carcinoma of the uterine cervix is the most common form of cancer in females. With the help of screening methods, its incidence can be reduced by identifying it in the premalignant stage. But due to ignorance at various levels and importantly women herself, it becomes difficult to achieve the target of eliminating it. For the same reason WHO recommended “once in a life time screening at the age of 40 years”.
Objective: This study aimed at evaluating cervical lesions in women of the target age group, by both cytology and colposcopy and to study the correlation between the two.
Methods: This study was conducted over 500 women in the department of obstetrics and gynaecology SNMC, Jodhpur targeting the age group of 35–45 years.
Results: 54% of pap smear were normal, 42% Inflammatory, 1.2%ASCUS, 1.8%ASC-H and LSIL, respectively, 0.8% HSIL. 38% of colposcopy findings were normal, 24% abnormal and 34.8% miscellaneous. Colposcopy-directed biopsy was taken in 85 women out of which 8 showed cervical dysplasia, 1 had CIN1, 5 had CIN II and 1 non-keratinizing squamous cell carcinoma. In women with cervical dysplasia, 75% were among 35–40 years.
Conclusions: All the women in the age group between 35–45 years should have at least cervical screening as it not only increases the detection rate but also helps in diagnosis of other cervical pathologies. We found stronger correlation between colposcopic findings as compared to correlation between pap smear and biopsy findings. Colposcopy-directed biopsies should be the gold standard as it not only identifies cervical dysplasia but also helps in taking targeted biopsies.

Objectives: In the present study, we compared the Simplified RCI with Swede score and correlated the findings with the histopathology reports.
Methods: In the present prospective study, 6390 women aged 25 to 65 years were screened by pap and VIA. 5181 pap smears were submitted and reported as 4049 NILM, 68 ASCUS. In Simplified reid’s colposcopic index (Simplified RCI), cervix was divided into four quadrants, and examination was done in a clockwise direction starting from the right upper quadrant; each quadrant was scored and documented in an equation style. The colposcopic findings of 147 women were scored by Simplified RCI and Swede score and compared. Reports and findings of Pap, VIA, Simplified RCI and Swede score were correlated with histopathology reports. Diagnostic performance of pap smear, VIA, Simplified RCI and Swede score was analyzed using sensitivity, specificity, positive and negative predictive values, accuracy analysis methods. ROC analysis was also performed to calculate the area under curve (AUC) and sensitivity and specificity at various cutoff values. Pearson’s correlation coefficient was calculated to test the association of Simplified RCI and Swede score.
Results: In present study for pap smear, sensitivity 75.60%, specificity 100%, PPV 100%, and NPV 76.70% with accuracy of 86.49% were calculated. For VIA sensitivity 97.60%, specificity 90.90%, PPV 93%, and NPV 96.80% with accuracy of 94.59% were calculated. ROC analysis showed that Pap and VIA could predict pre-invasive cervical lesions for cervical cancer at 88% and 94%, respectively. Simplified RCI and Swede score had a good correlation with the correlation coefficient ® 0.983; P < 0.0001. AUC of ROC of both tests showed excellent performance with 0.937 for Simplified RCI and 0.936 for Swede score. At cut-off of 3 for Simplified RCI sensitivity 100%, specificity 69.70%, PPV 80.40%, and NPV 100% with accuracy of 86.49% were calculated. At cut-off of 4 for Swede score sensitivity 97.60%, specificity 60.60%, PPV 75.50%, and NPV 95.20% with accuracy of 81.08% were calculated.
Conclusions: Pap smear and VIA are very good and effective method for cervical cancer screening. Pap smear is less sensitive (76%) as compared to VIA (98%) but more specific (100%) than VIA (91%). Simplified RCI performed well in terms of both sensitivity (100%) and specificity (70%), though Swede score is also very much comparable and acceptable with sensitivity (98%) and specificity (61%). Simplified RCI was easier to document and to recall the colposcopic findings of particular case with formula, which makes follow-up easier. In Swede score, the criterion of size of lesion is measured in millimeters, which is difficult in clinical practice and is extrapolated as number of quadrants. In contrast to this Simplified RCI scoring system is based on lesion findings of each quadrant separately, thus making its use more user friendly.
Regional Cancer Centre, Thiruvananthapuram
Background: Colposcopy was introduced to aid cervical biopsy to detect premalignant lesions of cervix. Reid, Swede and IFCPC scores were later introduced to avoid subjective variation.
Objectives: To study correlation between colposcopy scores like Reid score, Swede score and IFCPC scores with histopathology in screening positive patients.
Methods: Prospective study of patients who underwent colposcopy for cervical cancer screening from June 2018 to January 2021. Reid score, Swede score and IFCPC score were documented in colposcopy charts. Colposcopy scorings and histopathology were statistically assessed using spearman’s rank correlation test.
Results: Out of total 220 females screened average age was 49.75. Reid score > 4 correlated with 62.3% of high-grade histopathology (p = 0.149), Swede score > 5 correlated with 61.3% of high-grade histopathology report (p = 0.038), while IFCPC score as major lesion correlated with 78.3% of high-grade histopathology (p = 0.001). Reid score has sensitivity 62.3%, specificity 47.4%; Swede score has sensitivity 61.3%, specificity 52.6% with histopathology. IFCPC scoring had sensitivity 78.3%, specificity 47.4% with histopathology. Measurement of agreement kappa was 0.096 for Reid score, 0.139 for Swede score and 0.254 for IFCPC score. P value was significant with IFCPC score, 0.001.
Conclusions: IFCPC scoring has a better correlation and more sensitivity in detecting high-grade lesion while swede score is more specific in detecting high-grade lesion.

Objectives: To correlate between colposcopy-directed punch biopsy and loop electrosurgical excision procedure (LEEP) in cervical intraepithelial neoplasia and also to determine the prevalence of cervical intraepithelial neoplasia in patients based on abnormal colposcopy findings.
Design: Prospective Observational study.
Methods: All women attending Gynaecological Outpatient department at tertiary care centre, who had given consent for study and met the inclusion and exclusion criteria of reproductive age group (22–55 years) screened for cervical intraepithelial neoplasia (CIN) by visual inspection via acetic acid (VIA) and/or cervical cytology by liquid-based cytology. All the patients with positive VIA and abnormal cervical cytology findings will be subjected /screened by colposcopy examination. A sample size of 150 patients were taken for performing colposcopy.
Results: Total 150 were subjected to colposcopy-directed biopsy, only 39 subjects were reported to have CIN and rest of subjects were diagnosed as having cervicitis. LEEP was performed on these 39 subjects. The Kappa statistics were 0.4104 with agreement of 64.10% with p value 0.0001 and Spearman’s correlation was 0.5335 with p value 0.0005 which was highly significant.
Conclusions: There is statistical correlation between colposcopy-directed biopsy and LEEP in patients of cervical intraepithelial neoplasia and LEEP is gold standard.

Objectives : Cervical cancer is the most common gynaecological cancer in developing countries. Screening all women at risk especially in developing countries is helpful in decreasing the incidence. The Objective of the present study was to evaluate suspicious cervix with routine Pap test and concurrent colposcopy using revised IFCPC terminology and to correlate cytology and colposcopic findings with histopathological findings.
Methods : A prospective cross-sectional study was done on 90 women fulfilling inclusion criteria. Cytology and office colposcopy were performed simultaneously and grading of the disease was done according to revised IFCPC terminology 2011. Biopsy was taken from abnormal area observed on colposcopy.
Results : Colposcopy and Pap test was done in 90 women with unhealthy. Out of 90, 10 cases were excluded from study as it was inadequate findings on colposcopy. In demographic profile mean age was 43.2 years, majority (95%) were multipara and (57.5%) belonged to low socioeconomic group. A total of 80 women had adequate colposcopic findings on general assessment &were graded according to revised IFCPC 2011. 35 out of 80 (43.7%) had minor changes out of that 32 (91.4%) were confirmed on histopathological analysis as CIN -1 & rest 3 (9.4%) were underdiagnosed on colposcopy as it was CIN-2/3 on histopathology. 14 out of 80 (17.5%) had major changes on colposcopy. Out of which 7 (50%) had CIN2/3 on histopathology. 4 out of 14 (28.5%) had carcinoma cervix. Rest 3 out of 14 (21.4%) had carcinoma in situ. IFCPC 2011 terminology is very effective in distinguishing between minor and major lesions; however, it is sometimes not helpful to distinguish between very early cancer &CIN-2,3 since most of the findings are overlapping. Sensitivity and specificity of Pap test was 38.4% and 87%while of colposcopy was 71.7% and 78.05%
Conclusions : Colposcopic evaluation using IFCPC 2011 terminology is more descriptive and reproducible. Concurrent use of Pap test and colposcopy in evaluation of premalignant lesions of unhealthy cervix should be recommended as they are complementary to each other.

Objectives : To evaluate the efficacy of Swede score in colposcopy for screening carcinoma Cervix in correlation with histopathological examination.
Methods: A Prospective observational study was conducted at Department of Obstetrics and Gynaecology of Sri Ramachandra Institute of Higher Education and Research, Chennai between January 2019–March 2020. A total of 85 sexually active women aged 21–65 years who met the selection criteria were initially included in the study. Colposcopy examination using Swede score was done followed by colposcopy-directed punch biopsies when Swede Score was between 1 and 10 (n = 76). Histopathological examination was compared with Colposcopy using Swede Score to measure the accuracy and validity of the test.
Results : Among 76 patients, Swede score colposcopy revealed 62 patients with score 1–4 suggestive of normal/low-grade lesion (LGL), 8 patients with score 5–6 suggestive of high-grade lesion (HGL) and 6 patients with score 7–10 suggestive of HGL/suspected invasive cancer. Swede score colposcopy was compatible with histopathology results in86.85%of patients. Of the 16 (21.06%) cases of biopsy-proven cervical intraepithelial neoplasia1 (CIN), 12 (19.35%) were rightly identified during colposcopy. Biopsy-proven cases of CIN 2/CIN3/invasive Cancer were rightly identified as HGLs by colposcopy using Swede score in this study with 100% sensitivity and 89.8% specificity for HGL.
Conclusion : Colposcopy impression using Swede score with its good sensitivity and specificity in correlation with histopathological examination is found to be a good screening test for Cervical cancer especially in detecting HGL.
Department of Obstetrics and Gynaecology, National Hospital, Abuja.
Objectives: Colposcopy is a diagnostic procedure with a primary goal of identifying precancerous and cancerous lesions so that they may be treated early. To evaluate the Pap-smear results and colposcopic findings performed in the first 5 years of setting up one of the two colposcopy units of our hospital.
Methods: A study of 137 patients who were referred to the gynaecology clinic for colposcopy during the study period between January 2013 to December 2018 was carried out. Data was extracted from the records department of National Hospital, Abuja and same was analysed using simple statistical methods.
Results: Amongst the one hundred and thirty-seven patients studied, 69.3% were referred on account of abnormal pap smear (49.6% of whom had a result of low-grade squamous intraepithelial lesion and 19.7% for high-grade lesion). 26.2% were referred on account of a suspicious cervix and 4.4% for persistent inflammatory smears. Abnormal colposcopic findings were reported in 49.6% of the study group who subsequently had colposcopically directed biopsies.
Conclusion: The combined use of Pap-smear and colposcopy in the detection of premalignant and malignant lesions of the cervix increases the success and enables early diagnosis and appropriate treatment.
Gandhi Medical College and Sultania Hospital, Bhopal, India
Objectives: Study of colposcopic and histopathological correlation for cervical cancer lesions at tertiary care centre.
Methods: This is a observational study done over one year of all outpatient and inpatient females of age more than 20 years presenting with white discharge, menstrual abnormality, abnormally looking cervix, VIA positive, sexually transmitted disease and abnormal pap smear. Data was collected from cases and analysed. Grouped data was expressed as frequency and percentage, whereas numerical data was expressed as mean and standard deviation. Correlation between colposcopy and histopathological diagnosis was established.
Results: Out of 89 cases of chronic cervicitis, 47.2% cases were diagnosed as inflammation whereas 22.5% were identified as CIN I on colposcopy. However, 18% chronic cervicitis cases were identified as normal on colposcopy. All the histopathological cases of polyp were diagnosed as polyp on colposcopy. Out of 22 cases of CIN I on histopathology, colposcopy revealed CIN I in 32% cases. Similarly, histopatho-colposcopic correlation for CINII and CIN III cases were noted in 41.7% and36.4%cases, respectively. Out of 4 cases of squamous cell carcinoma, none of the cases were diagnosed as cancer on colposcopy. The observed correlation between histopathology and colposcopy was statistically significant (p < 0.01). Diagnostic accuracy, sensitivity, specificity, PPV and NPV was 77.2%, 78.6%, 76.1%, 72.7%, and 81.4%, respectively.
Conclusions: Colposcopy has a good correlation with histopathology for identification of premalignant lesions and may obviate the need for repeated pap smear. Therefore combined approach (PAP's Smear, colposcopy, biopsy under colposcopic guidance is recommended.

Objective: See & Treat at colposcopy has been described for high-grade abnormalities on the Pap smear with high-grade lesions on colposcopy. Visual Inspection with Acetic Acid (VIA) is a low cost screening test for LMICs. Colposcopy and treatment at the same sitting prevents loss to follow-up. The objective in the present study was to evaluate the efficacy of SEE AND TREAT approach by LLETZ in VIA positive women having high-grade lesions on colposcopy.
Design: Prospective Interventional Study.
Method: Women in the age group of 25–50 years and coming to the general gynaecology clinic had opportunistic screening with VIA; those who were VIA positive underwent Colposcopy and SEE and TREAT using LLETZ if the Colposcopy findings were suggestive of a high-grade lesion. Treatment was defined as acceptable if the histopathology showed CIN; overtreatment if there was no CIN.
Results: Colposcopy was performed in 688 women who were VIA positive; of them 101 had a high-grade lesion and underwent LLETZ. All of them had CIN on histopathology; 35 (34.6%) had CIN 1, 55 (54.5%) had CIN 2 and 11 (10.9%) has CIN 3. The SEE and TREAT approach was acceptable in all and there was no overtreatment in any case. There were no major complications.
Conclusion: VIA followed by SEE AND TREAT approach at colposcopy is acceptable and can reduce loss to follow-up.

Objectives: Swede Score can objectively assess the grade of acetowhite lesions at colposcopy. Determining a cut-off Swede score predictive of high-grade CIN would help triage women to See & Treat Approach by LLETZ.
Design: Prospective Interventional Study.
Method: Women in the age group of 25–50 years and coming to the general gynecology clinic had opportunistic screening with VIA and Colposcopy if VIA positive. Acetowhite lesions at colposcopy were scored by the Swede score; a cut-off for Swede score of ≥ 5 was used to triage women for SEE and TREAT approach using treatment with LLETZ. Predictive value of each score ≥ 5 was calculated by ROC curves using histopathology as the gold standard.
Results: Colposcopy was carried out for 688 women who were VIA positive; 101 had a colposcopy score of ≥ 5 and underwent LLETZ, all had CIN on histopathology. Swede score was between 5–7 in 91 women (90.10%), 36.26% had CIN 1 while 63.74% had CIN 2+. The score was ≥ 8 in 10 (9.90%) of them, 20% had CIN 1 and 80% had CIN 2 + . The predictive value for CIN 2 + was best at a score of > 5.
Conclusion: Swede Score of 5 best identifies a high-grade lesion suitable for SEE AND TREAT approach by LLETZ.

Objective: In the present study, we compared the simplified RCI with Swede score and correlated the findings with the histopathology reports.
Methods: In the present prospective study, 6390 women aged 25 to 65 years were screened by Pap smear and VIA. Colposcopic findings of 147 women were scored by Simplified RCI and Swede score; and compared. Reports and findings of Pap, VIA, Simplified RCI and Swede score were correlated with histopathology reports. Diagnostic performance of pap smear, VIA, Simplified RCI and Swede score was analysed using sensitivity, specificity, positive and negative predictive values, accuracy analysis methods. ROC analysis was also performed to calculate the area under curve (AUC) and sensitivity and specificity at various cutoff values. Pearson’s correlation coefficient was calculated to test the association of Simplified RCI and Swede score.
Results: In present study, for pap smear sensitivity 75.60%, specificity 100%, PPV 100%, and NPV 76.70% with accuracy of 86.49% were calculated. For VIA sensitivity 97.60%, specificity 90.90%, PPV 93%, and NPV 96.80% with accuracy of 94.59% were calculated. ROC analysis showed that Pap and VIA could predict pre-invasive cervical lesions for cervical cancer at 88% and 94%, respectively. Simplified RCI and Swede score had a good correlation with the correlation coefficient (r) 0.983; P < 0.0001. AUC of ROC of both tests showed excellent performance with 0.937 for Simplified RCI and 0.936 for Swede score. At cut-off of 3 for Simplified RCI sensitivity 100%, specificity 69.70%, PPV 80.40%, and NPV 100% with accuracy of 86.49% were calculated. At cut-off of 4 for Swede score sensitivity 97.60%, specificity 60.60%, PPV 75.50%, and NPV 95.20% with accuracy of 81.08% were calculated.
Conclusions: In the present study, we found that Pap smear is less sensitive (76%) as compared to VIA (98%) but more specific (100%) than VIA (91%). Simplified RCI performed well in terms of both sensitivity (100%) and specificity (70%), though Swede score is also very much comparable and acceptable with sensitivity (98%) and specificity (61%). Simplified RCI was easier to document and to recall the colposcopic findings of particular case with formula, which makes follow-up easier. In Swede score, the criterion of size of lesion is measured in millimetres, which is difficult in clinical practice and is extrapolated as number of quadrants. In contrast to this Simplified RCI scoring system is based on lesion findings of each quadrant separately, thus making its use more user friendly.

Objective: To assess the role of direct colposcopy for screening of precancerous and cancerous lesion of cervix.
Methods: A cross-sectional study was done in the department of OBGY and department of pathology, VMMC & SJH for 12 months. An opportunistic screening done in the OPD post which screen positive women either by visual inspection by acetic acid or Lugol’s iodine/PAPS/HPV DNA and followed by colposcopy. Direct colposcopy was done in women having unhealthy-looking cervix. Women with positive findings on colposcopy were subjected to four-quadrant directed cervical biopsy. Pregnant women, women having active vaginal bleeding or any past treatment for cervical lesion were excluded from the study.
Results: A total of 70 colposcopies were done out of which 35 were done in screen positive women (Group 1) and 35 were direct colposcopy for unhealthy looking cervix (Group 2). Demographic data like median age, mean parity, lower socioeconomic status, age < 18 years at first sexual contact, first child birth at age < 18 years, addictions (smoking/tobacco) and contraceptive use was comparable in both groups.
Colposcopy was adequate in all women. Abnormal colposcopy was noted in 75% patients in Group 1 (55% minor grade & 20% major grade) and 60% patients in Group 2 (38% minor grade & 22% major grade). In Group 1 cervical biopsy showed benign pathology in 16, CIN 1 in 6, CIN 2/3 in 3 & malignancy in 1 woman and in Group 2 benign in 14, CIN 1 in 3, CIN 2/3 in 3 and malignancy in 1 woman.
Conclusion: Direct colposcopy is a useful method to detect pre-cancerous and cancerous lesions of cervix.

Objective: Evidence for using colposcopy in absence of a squamous intraepithelial lesion on conventional cytology has an important position in cervical cancer screening. Aim of this study was to evaluate diagnostic accuracy of colposcopy against cytology in unhealthy cervix for timely detection of preinvasive and invasive cervical lesions.
Method: Prospective study. 496 diagnostic colposcopies on women with unhealthy cervix on examination were performed in one year. Concurrently cytology was done as routine protocol. 99 women having high-grade colposcopy (Swede score ≥ 5) underwent guided biopsy and tissue was evaluated histopathologically. Cytology of same patients were compared.
Results: Mean age of women was 42.68 ± 11.69 years and mean age at consummation of marriage 20.94 ± 3.21 years. Cervical erosions were common findings (41.4%) followed by hypertrophied cervix (33.3%) and cervix bleeding on touch (17.2%). 24.14% women with ASCUS cytology had high-grade histopathology (CIN2 +), while 42.3% women with LSIL had high-grade histopathology (CIN2 +). Taking ASCUS and above as cut-off, the sensitivity, specificity of Pap smear was 97.8%, 14.6% and diagnostic accuracy was 55.3%. For overall analysis of colposcopy Swede Score at ≥ 5, colposcopy was 100% sensitive and 41.2% specific and diagnostic accuracy was 69.7%. At swede score ≥ 7, colposcopy was 64.6% sensitive and 100% specific and diagnostic accuracy was 82.8%.
Conclusion: Women with cytology reports of ASCUS and LSIL had CIN 2 + on histopathology thereby highlighting drawbacks of conventional cytology. Colposcopy can be used as a valuable concurrent tool in women with unhealthy cervix and high-grade colposcopy can be taken up for biopsy without awaiting initial cytology in such women.

Background and Objective: The Reid’s Colposcopy Index (RC) relies on critical analysis rather than on pattern recall. The primary objective was to assess the agreement between colposcopy and histopathological grading of lesions of cervix. The secondary objectives were to correlate social demographic data with incidence of cervical preinvasive and invasive lesions and to determine the diagnostic efficacy of colposcopy.
Methods: One hundred sexually active women above 18 years age with complaints of vaginal discharge, intermenstrual or postcoital bleeding, unhealthy-looking cervices, nonconclusive/abnormal cytology report were included in a single center, prospective, observational study over 2 years. Screen positive women using Pap smear were reffered for colposcopy. Reid’s Colposcopy Index was calculated and biopsy was taken at site with the highest score and sent for histopathology (HPE). Colposcopy diagnosis according to RC were compared with HPE and sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), accuracy and strength of correlation was observed. Statistical significance was derived using weighted Kappa “k” correlation coefficient and p value.
Results: Colposcopy when compared to histopathology had a sensitivity of 100%, specificity of 48.3%, with PPV of 22.4% and NPV of 100%. The p value was 0.001 suggesting a significant strength of agreement between colposcopy diagnosis using Reid’s index and histopathological diagnosis.
Conclusion: Using a scoring system like RCI can help in reducing interobserver variability and may be useful for further follow-up of low-grade lesions, provided site specification is added. Hence, it greatly simplifies learning colposcopy.

Objective: To look for the presence of colposcopic signs inner border, ridge and rag sign in women with abnormal cervical cytology and to correlate the colposcopic findings with histopathology.
Design: Cross-sectional observational study.
Methods: Eighty-two women with abnormal cervical cytology were included. A detailed history was taken and examination done followed by colposcopic assessment of the cervix, with special attention to inner border, ridge and rag signs. Colposcopic-guided biopsies were obtained. Taking histopathology as gold standard the diagnostic accuracy of colposcopic signs was calculated.
Results: Grade 2/3 aceto-white areas were present in 38 cases. Inner border sign was seen in 9 cases, ridge sign in 21 cases and rag sign in 13 cases. The sensitivity, specificity, positive Predictive Value, Negative Predictive Value, diagnostic accuracy of Inner border sign was 28.12%, 100%, 100%, 68.49% & 71.95%, respectively; for Ridge sign was 65.62%, 100%, 100%, 81.97% & 86.59%, respectively; for Rag sign was 37.5%, 98%, 92.31%, 71.01% & 74.39%, respectively.
Conclusions : The presence of these colposcopic signs is highly predictive for high-grade cervical intraepithelial neoplasia. These signs are easy to learn, less time consuming and have better diagnostic accuracy. While cytology remains the gold standard for screening of carcinoma cervix, it is important to complement it with colposcopic pathognomic signs—guided biopsy for early detection and management of cervical carcinoma.

Objective: To find the predictive value of VIA, HPV genotyping and colposcopy for predicting CIN in women screened by opportunistic primary HPV screening.
Design: Cross-sectional observational study.
Method : Testing for high-risk human papillomavirus by conventional PCR was carried out in 1606 sexually active women ≥ 30 years attending the gynaecology clinic, 137 women were HPV positive who had HPV genotyping, Visual Inspection with Acetic acid (VIA), colposcopy and biopsy sequentially. The sensitivity, specificity, PPV & NPV at 95% CI of VIA positivity and AUC for predicting CIN 2 + was compared using histopathology as the gold standard.
Results: The HPV prevalence rate in the 1606 women screened was 8.5%. The sensitivity of HPV 16, 18 genotyping was 82.1% (95% CI 63.11% to 93.94%) for VIA 71.43% (51.33% to 86.78%) and Colposcopy was 96.43% (81.65% to 99.91%). The specificity was 13.04% (95% CI 6.93% to 21.68%) for HPV 16,18; 43.48% (33.17% to 54.22%) for VIA and 30.43% (21.27% to 40.90%) for Colposcopy. ROC area under curve for HPV 16,18 was 0.48 (95% CI 0.38 to 0.57), VIA was 0.57 (95% CI 0.48 to 0.66) and Colposcopy was 0.63 (95% 0.54 to 0.72). Colposcopy missed one case of CIN 2+, HPV 16,18 missed 5 and VIA missed 8.
Conclusion: Direct colposcopy should be considered in women detected screen positive at the health facility to minimize loss to follow-up and detect and effectively treat high-grade CIN.
Hospital Universitario 12 de Octubre, Spain
Objectives : The aim of this study is to analyze the cases assessed in our center between 2013 and 2018 with cervical cytologies suspected of infiltrative injury from the screening program in asymptomatic patients in force in our area and the cytohistological correlation after its study in the cervical pathology unit.
Methods : Retrospective descriptive analysis of a total of 10 patients who, after performing the current population oppotunistic screening, were referred to our cervical pathology unit with the result of cervical cytology suspected of infiltrative injury between 2013 and 2018. The subsequent statistical analysis was performed with SPSS 25.
Results : All cytologies of our study (10) were reported as suspected of malignancy. The result of the subsequent biopsy showed 50% CIN 3, 10% CIN 2, 10% in situ adenocarcinoma, 10% carcinoma, in one case no biopsy was performed and in another case the biopsy was negative.
The subsequent pathological results after conization were the following: two cases of squamous cell carcinoma (20%), one case of adenocarcinoma (10%), and the rest were informed as no cancer (70%). Therefore, of the 10 cytologies that were initially reported as suspected of malignancy, the diagnosis of malignant pathology was confirmed in 30% of them.
Conclusions : In our study group, cyto-histological concordance is lower for suspected infiltration than that described in the literature. However, the small sample size does not allow obtaining statistically significant comparative results. It should also be noted that these cytological findings only come from patients from population screening without prior clinical suspicion.

Objectives: To study the association of human papillomavirus (HPV) with various types of benign and premalignant cervical abnormalities.
Methods: The study was conducted in tertiary care hospital between January 2014 to December 2015. After taking due informed consent, 500 sexually active women reporting to obstetrics and gynecology outpatient department were recruited. Inclusion criteria were clinically detected cervical abnormalities or abnormal cytology or histopathology. Patients diagnosed with malignancy were excluded. Among these, 50 patients were randomly selected for HPV DNA testing with abnormal cervical cytology. Patients having positive VIA; VILI or pap smear findings underwent colposcopy-guided biopsy.
Results: Most common cervical abnormality clinically was erosion (28%), and cevical hypertrophy (25%) bleeds on touch (18%). Most common cervical abnormality on cytology was bacterial vaginosis (32%), candidiasis and trichomonas (15%), squamous metaplasia (12%). Most common cervical abnormality on colposcopy-guided cervical biopsy was chronic cervicitis (65%), mild dysplasia (5%), severe dysplasia in 3%. Among cytologically positive patients 12% had positive HPV DNA. HPV 11 was positive in LSIL lesions and HPV 16 was positive in HSIL lesion. one patient with CIS positive on cytology had HPV 11 + and also one patient with inflammatory smear had HPV11 + . On correlating cervical cytology with HPV sampling, p value was 0.004 and RR was 1.4 which shows good correlation.
Conclusions: HPV positivity was significantly high in benign and premalignant lesion of cervix, so all women with cervical abnormality should be screened for HPV. All inflammatory smears should also be kept in follow-up.

Objectives : To correlate Pap smear findings with histopathology reports and to assess the efficacy of Pap smear in cervical cancer screening.
Methods: It was a prospective study conducted in Department of Gynaecologic Oncology at Action Cancer Hospital from March 2018 to February 2019. Total 59 symptomatic sexually active women who had undergone both Pap smear and colposcopy-directed cervical biopsy were included in this study. Correlation between cytology and histopathology was analysed. Qualitative variables were correlated using Chi-Square test/Fisher's exact test. Diagnostic test was used to calculate sensitivity, specificity, negative predictive value (NPV), positive predictive value (PPV). Inter-rater kappa agreement was used to find out strength of study.
Results: Out of 59 Pap smears, maximum patients (35.59%) belonged to age group 41–50 years. Mean age was 43.32 years. On Pap smear,54.24% had NILM,15.25% had LSIL, 15.25% had HSIL,6.78% had ASCUS,5.08% had ASC-H and 3.39% had SCC. 74.58% had HPV testing, out of which 59.09% were positive for high risk HPV DNA. On histopathology, 40.68% had chronic cervicitis (CC), 18.64% had CC with squamous metaplasia, 15.25% had CIN 1,10.17% had CIN 2, 6.78% had CIN 3 and 8.47% had SCC. Overall sensitivity, specificity, PPV, NPV, and strength of study were 83.33%, 80%, 74.07%, 87.5% and 0.621 (Kappa value). Out of 59 cases,48 cases (81.36%) diagnosed on Pap smear correlated on histopathology.
Conclusions : Maximum number of Pap smear findings correlated on histopathology. So Pap smear can be used as a good screening tool for cervical cancer screening.

Objectives: This study aimed to know the prevalence of abnormal Pap smear in pregnant women by liquid-based cytology.
Methods: Cross-sectional study done at a tertiary care hospital, India from August 2017 to January 2019. Six hundred pregnant women attending the OPD at their first visit were enrolled and after taking history and clinical examination, subjected to cervical cancer screening by liquid-based cytology (LBC).
Results: Out of 600 samples,10 samples (1.67%) were unsatisfactory for evaluation due to low cellularity. Among 590 samples, only 2 reported as LSIL (Low-grade squamous intraepithelial lesion) and 588 reported as NILM (Negative for intraepithelial lesion or malignancy). Inflammation of varying degree, mild, moderate and dense was reported in 58.65%, 24.92% and 16.44%, respectively. Infection was reported in 3.73% and Candida, Trichomonas and Gardnerella species were present in 2.71%, 0.51%, 0.51%, respectively. Statistically significant correlation (p value < 0.0001) was seen between level of education and knowledge about cervical cancer screening. A statistically significant correlation (p value 0.013) was also seen between abnormal per speculum cervical findings and prevalence of infection in the LBC report of the screened antenatal women.
Conclusion: Antenatal period can be used as an opportunity to screen women for cancer cervix. There is low number of unsatisfactory smears with liquid-based cytology, only 1.67% of the smears were unsatisfactory for evaluation. Added advantage of doing cervical cytology in pregnancy is that in some women infective organisms can be picked up.

Conclusions: The use of DS in low-risk cytology increases the detection of patients with high-grade.
Department of Pathology, Government Medical College Kottayam, Kerala, India
Objectives: Cervical cancer is one of the leading cause of mortality and morbidity among women worldwide. In India, it accounts for 25% of cancer deaths. Only limited number of studies are available on prevalence of cervical epithelial abnormalities, especially in Kerala. The objective of the study was to estimate the prevalence of cervical cytological pattern in central Kerala, so appropriate screening strategies can be planned.
Methods: A 1-year descriptive study was conducted on Cervical pap smears in study population groups: (1) Camp population from various camps conducted in and around Kottayam and (2) Hospital population and received in the department of Pathology, Government Medical College, Kottayam during the study period of 12 months. Smears were assessed according to the revised Bethesda System 2014. A total of 240 cases of Pap smears were analysed in each group of population (hospital and screening camp).
Results: The mean age of population in the present study was 48.20 ± 10.224 SD in camp and 48.23 ± 11.339 SD in hospital population. Majority belongs to the age group 41–50 years. In both majority of the smears were negative for intraepithelial lesion or malignancy (NIL/M). Epithelial abnormality was seen in 1.25% cases (LSIL) of camp population & 2.5% cases (ASC-US, LSIL and HSIL 0.80% each) of hospital population.
Conclusion: Our study shows a relatively low prevalence of cervical epithelial abnormality similar to developed countries. Pap smear is an effective screening procedure to detect cervical cytological abnormalities. Routine screening should be offered to all women above 21 years. It is recommended to improve awareness about disease among females.
Agartala Government Medical College, India
Objectives : To evaluate feasibility of screening tools VIA& HPV-DNA in detection of premalignant lesions of cervix. To evaluate simultaneous testing feasibility of screening tools of VIA and HPV-DNA in detection of premalignant lesions of cervix taking Pap smear as gold standard.
Design : Cross-Sectional Study.
Method s : Study was done in Department of Obstetrics and Gynaecology OPD, AGMC& GBPH from JANUARY 2018 to JUNE 2019, total 360 patients aged (30–65) were subjected for study and simultaneous test was done.
Result s : PAP positive 17.5%, PAP negative 82.5%. Positive case includes LSIL 6.11%, HSIL 6.94%, malignancy 3.88%. HPV-DNA positive 24.16% and negative cases are 75.83%. VIA positive 20% and 80% were negative. VIA compared to final diagnosis was 57.14% with specificity of 89.89%, PPV of 48.27% and NPV of 77.16%. HPV-DNA compared to final diagnosis was 83.66% with specificity of 89.22%, PPV of 56.16% and NPV of 76.58%. The net sensitivity of both HPV DNA and VIA compared to final diagnosis 95%, specificity 80.1%, PPV 50.42%, NPV 98.75%.
Conclusions : The role of pap smear for cervical cancer screening has long been established in the West but it is not a very feasible test for a resource-limited setting. Alternative methods such as VIA may be very useful in a resource-limited setting but VIA has low sensitivity and may not perform well as stand-alone tests, so adjunctive tests are one way of improving specificity of the test. Our study has confirmed simultaneous assessment of VIA & HPV-DNA gives an excellent positive predictive value in cervical screening.

Objective : To know the prevalence of abnormal cytology in women with symptoms of STI (Sexually Transmitted Infections).
Design : Cross-sectional study at a teaching hospital in Northern India.
Methods : All Women attending STI clinic and gynaecology clinic with suspicion of STI, had a detailed history and examination, speculum examination and pap smear taken by LBC using the SurePath sampler. Blood samples for HIV & VDRL were taken from all; women with vaginal discharge had swabs from vagina, urethra & cervix for wet mount, gram & Giemsa stain, microscopy and culture for trichomonas, candida, gonorrhea, chlamydia, bacterial vaginosis, Haemophilus ducreyi and KOH mount for candida.
Results: There were 222 women in the age group of 21-60yrs (mean age 28 yrs). The STIs detected were candida in 58 (26.1%), bacterial vaginosis in 12 (5.4%), syphilis in 13 (5.8%), herpes genitalis in 10 (4.5%), genital warts in 32 (14.4%), HIV in 8 (3.6%), molluscum contagiosum in 34 (15%), trichomonas vaginalis in 2 (0.9%), ureaplasma/mycoplasma in 2 (0.9%). No specific organism were found in 47 (21.1%). Overall 7.6% of these women showed abnormal cervical cytology, inflammatory in 8 (3.6%), ASCUS in 4 (1.8%), LSIL in 2 (0.9%).
Conclusion : Women with STI have high risk of developing cervical cancer and should be screened and followed up regularly.
Dr D.Y.Patil Medical College and Hospital, Pimpri, Pune, Maharashtra, India
Objectives: To compare cytomorphological features and cytologic diagnosis on Conventional Papanicolaou (CP) smears with liquid-based cytology technique, EziPREP™, for cervical smears
Design: A prospective study with consecutive cervical sampling was conducted on 100 women attending the OPD at our institute.
Methods: CP smears were prepared as per the standard technique using Ayre’s spatula. EziPrep™ required sample collection with endocervical brush followed by detaching the head of brush into the fixative vial. The EziPREP™ samples were then processed as per the manufacturer's protocol. Both CP and EziPREP™ smears were stained using standard Papanicolaou as well as H&E staining protocols. Slides were analysed by two pathologists independently.
Results: The unsatisfactory rate for CP was 16%, main cause being obscuring haemorrhage and inflammation, whereas on EziPrep™ samples it was 4%, owing to inadequate cellular material. Staining quality was better in EziPREP™. The morphological details were comparable in both sets of smears. The pathogenic organisms, like Candida and Trichomonas, were better appreciated in EziPREP™ samples. Cellular atypia was better appreciated in CP smears. There was a 98% concordance in cytologic diagnosis between CP and EziPREP™ smears. Screening time was notably reduced in EziPREP™ smears (2 ± 0.5 minutes vs 4 ± 0.5 minutes for CP).
Conclusion : Owing to the better smear quality, reduced number of unsatisfactory smear and reduced screening time, EziPREP can be considered superior to Conventional Pap smear. The availability of such comparatively low-cost devices may help in wider application of liquid-based cytology cervical screening in low-resource countries.
Labaid Specialized Hospital, Bangladesh
Objectives: Cervical cancer is the second-most prevalent cancer of women in Bangladesh. It is one of the major public health problems due to high mortality rate as most patients (80%) are diagnosed in the advanced stage. It is mostly preventable if detected early by screening test. The main purpose of the study is to assess the level of knowledge and awareness of cervical cancer prevention and screening among the women attending OPD of Gynae and Obstetrics.
Methods : This cross-sectional study was performed among the women attending the OPD of Obstetrics and Gynaecology in Shaheed Suhrawardy Medical College Hospital from June 2018–September 2018. A total of 300 respondents were selected by random sampling. All the information collected in a structured questionnaire and data were analyzed using SPSS.
Results : The majority of our respondents reported having very poor knowledge about cervical cancer. Mostly it is related with the women with low levels of general health education & illiteracy. Only 31.23% women reported to have some knowledge about cervical cancer wanted to perform screening. Poor knowledge of husbands, his occupation, unwillingness, monthly income and age of the women observed other associated factors. Majority of respondents (83.31%) had no idea of HPV vaccination. Women aged over 40yrs were unaware about cervical cancer.
Conclusion : Most of the women do not know clearly about cervical cancer prevention strategy, risk factors, screening and vaccination. Health education, promotion of screening program, raising awareness about its vaccination is most cost-effective approach in reducing incidence of cervical cancer in low-resource countries like Bangladesh.
Institute for Rural Health Studies, Telangana, India
Objectives: Cervical cancer is both preventable and curable if detected early. In resource-constrained settings nurse’s role becomes very crucial, where screening and treatment is taken close to their door steps especially in rural and remote areas. We report the role of trained nurse midwives in effective implementation of cervical screening program with remote supervision in a district hospital.
Methods : We have retrospectively analysed various activities undertaken by the trained nurses from an ongoing organized cervical cancer screening program in Mahabubnagar district, Telangana state, India from the year 2007 onwards. Nurses recruited eligible women by providing facts about prevention of cervical cancer, ensured their consent for screening, performed VIA screening, informed the test results, offered appropriate treatment and advice if found abnormal test results, encouraged non-responders to use these services in accordance with their culture, etc.
Results: Over 51,000 women between 25–60 years were motivated and screened opportunistically in the Women’s cancer screening clinic of district hospital during 2007–2019 (12 years). Nearly 300 women with invasive cancers were identified and about the same number of women with pre-cancers were detected and treated. A vast majority of genital infections were also treated.
Conclusion : Intensive training, timely guidance and supervision to the nurses is an ideal solution where public health resources are limited. These nurses are a perfect alternative to a physician in cervical screening and treatment. Their routine work can be easily supervised remotely and guided through if complication arises.
RDT hospital, Bathalapalli, Ananthpur, India
Objectives : Correlation of papanicolaou (PAP) smear and colposcopy in the detection of premalignant lesions of cervix.
Methods : Women aged 20–65 years attending Gynecology OPD. Women with frank lesions, acute PID, and those treated for carcinoma cervix.
Methods: For the study group Pap smear was taken after taking informed consent. Colposcopy was done for women with positive Pap smear (LSIL, HSIL, ASCUS & AGUS) with informed consent and explanation of the procedure. Colposcopy-directed biopsy. Histopathology reports correlated.
Results : Among total study Pap smears, only 4% were abnormal. In this study, positive predictive value (PPV) of pap smear is 74% and colposcopy is 80%. The peak age group was between 41–50 years.
Conclusions : In this study, incidence of cervical intraepithelial neoplastic I (CIN I) was 48%, CIN II 28%, CIN III 20%, squamous cell carcinoma 4%. This emphasizes the use of all 3 methods PAP cytology (conventional method), colposcopy, and histology is complementary to each other and helps to reduce false negative cases. However, strategic approach to cervical screening should be followed considering the resource settings like SEE & TREAT, SCREEN & TREAT strategies.
BRLSABVM Govt. Medical College Rajnandgaon, Chhattisgarh, India
Objectives: The study was undertaken to assess the major barriers that influence the utilization of cervical cancer screening among rural women of central India with the aim of helping health professionals to revise policies and practices.
Methods: It was a cross-sectional questionnaire-based study, conducted from January 2018 to December 2019 in the Department of Obstetrics and Gynecology at Government Medical College Rajnandgaon, the only tertiary care center of the district located in the southwest Chhattisgarh. A total of 897 women aged 21–65 years were included and assessed. Qualitative data were presented as frequencies and percentages by using SPSS version 21.
Results: Of the total,10.9% had heard of cervical cancer, while 6.8% had heard about cervical cancer screening. Unfortunately, only 0.6% women were screened by Pap test. None of them were ever heard of HPV vaccination. Although importance of screening and prevention had been thoroughly explained, despite the fact only 40% showed willingness to undergo cervical cancer screening in the future and HPV vaccination of their teenagers. However, it was very difficult to counsel and educate asymptomatic older population than symptomatic younger ones.
Conclusions: Intensive health education could be the major step to cross the major barrier of ignorance among rural population as well as healthcare provider’s. There is also a need of community-based interventions to increase and promote HPV immunization coverage. Finally, subsidization will go a long way in lessening the financial burden, as well as increase utilization by rural population to change the current scenario.
All India Institute of Medical Sciences, Rishikesh, Uttarakhand, India
Objectives: To compare the accuracy of various screening methods (Pap smear, VIA, VILI and Colposcopy) in cervical cancer in a limited-resource setting and to assess the knowledge, attitude and practice of the study population towards cervical cancer screening.
Methods: A total of 150 patients presenting to the gynaecology OPD at AIIMS Rishikesh were recruited from January 2019 till December 2019 and were sequentially screened with Pap smear, VIA, VILI and colposcopy. Suspicious lesions on colposcopy were subjected to cervical biopsy and KAP questionnaire was filled in the same sitting.
Results: Pap test showed a sensitivity of 40%, specificity 96.4%, positive predictive value 44.4%, negative predictive value 95.7% and diagnostic accuracy 92.67%. For VIA sensitivity was 57.1%, specificity 93.7%, positive predictive value 30.7%, negative predictive value 97.81%, and diagnostic accuracy 92%. For VILI sensitivity was 37.5%, specificity 95%, Positive predictive value 30%, negative predictive value 96.4% and diagnostic accuracy 92%. Only 4.6% had adequate knowledge, 11.3% were completely unaware of cervical cancer screening, 84% had suboptimal knowledge of cervical cancer screening. 62% showed favourable attitude towards screening and less than one percent were ever screened and none received the HPV vaccination.
Conclusion: All the three screening modalities Pap smear, VIA and VILI have similar diagnostic accuracy thus VIA and VILI can be used in resource-limited setting. The present study showed maximum sensitivity with VIA. It also showed that inadequate knowledge is the main barrier in utilisation of cervical cancer screening and vaccination services.
Geetai Nursing Home, Amravati, Maharashtra India
Objectives: To evaluate the impact of mobile cancer screening vehicle in screening for cancer cervix and cancer breast.
Methods: Cervical and Breast cancer is preventable by health education and early detection. Preventive services are sparsely available at community levels. We need to reach out to the under priviledged with the help of community /NGOs. For this purpose with the help of Rotary Club Of Amravati Midtown a van was designed to provide Pap smear collection and mammography testing services. The reading of Pap smears was done by cytology department Dr PDM medical College Amravati. Beginning from 2018 this van is visiting places and arranging screening camps all over India with the help of local Rotary clubs or other NGOs.
Results: From January 2018 we have covered all of Maharashtra, Madhya Pradesh, Chhattisgarh, Gujarat, Telangana reaching 31,943 women. 8102 mammography and 19,554 Pap smears were done. Out of these 657 abnormal Mammography and 1005 abnormal Pap smears were detected.
Conclusions
Mobile van is a very good tool for attracting crowds. It provides good opportunity for health education with the help of slide shows, poster exhibition and speeches by local Gynaecologists. Linkages between smear collection and receiving reports in time needs to be streamlined. Active collaboration between FOGSI, ISCCP. IMA members and NGOS would prove meaningful. Follow-up and treatment of abnormal lesions is most important and will be strengthened.

Tata Medical Centre, Kolkata, India
Objective: To evaluate HPV test for primary cervical screening in identifying factors of HPV persistence. Identify feasible triaging strategies for colposcopy referral and follow-up in primary HPV cancer screening.
Design: Prospective analysis of 2502 women (25–65yrs) screened with primary HPV test and longitudinal follow-up from January 2018–February 2021 at TMC, Kolkata.
Results: A total of 253/2502 (10.1%) women screened HPV positive and 226 (89%) underwent colposcopy. On directed biopsies, 46.1% had no CIN, 44.6% had koilocytosis and CIN1, 7.5% had CIN2 and 1.7% had CIN3 lesions. 232 (91.6%) women with ≤ LSIL were observed and 175 were retested for HPV between 12 to 24 months, 72% women tested HPV negative and 28% remained HPV positive at a median of 12 months of repeat HPV test. 21/232 women underwent an ablative/excisional procedure and 100% (14) in this follow-up period tested HPV negative. For triage strategy for ≥ CIN2 according to the different genotype: for HPV 16 (21.3%) the PPV was 11.1%, HPV 18 (14.6%) PPV was 13.5%. The PPV for ≥ CIN2 for any HPV genotype, 16&18 and HPV 16/18/31/33/45/52/58 was 8.3%, 11.6% and 9.3%, respectively.
Conclusion: In resource-limited setting, though HPV screening is highly sensitive and specific, a single round of HPV testing may create a burden on colposcopy resources. Persistence of HR-HPV infections plays an important role in the development of cervical cancer, hence, both screening and triage at a single visit or stratification of risk will be an effective strategy to reduce colposcopy referrals.
Malabar Cancer Care Society, South Bazar, Kannur, India
Objectives : In the present study, we analyzed our experience in cervical cancer screening from 2002 to 2020 as part of community-based screening.
Design: Retrospective analysis of prospective database of cervical cancer screening from 2002 to 2020 done by Malabar Cancer Care Society in Kerala.
Methods : The data on demography, type of screening, detection of precancerous and cancerous lesions was analyzed. Descriptive statistics were used to analyze the data.
Results: A total of 48,307 individuals were screened over 18 years. 55% were premenopausal. 33% were fully asymptomatic and remaining 66% had white discharge per vaginum (25%), bleeding per vaginum (14%) or combination of symptoms (25%). 18% had abnormal per speculum findings (bleeds on touch, discharge, etc.) 86% had unhealthy cervix.26% (12,650) had VIA/VILI and 74% (35,658) had pap smear. The pap smear findings were normal (41%), atrophic (17%), inflammatory (40%) and 2% had pre-cancerous/ cancerous changes. Of these lesions, 46% were HSIL, 36% were LSIL, 5% ASUS and 13% were squamous cell carcinoma (52 cases). 0.04% had invasive carcinoma detected by colposcopic biopsy after VIA/VILI whereas 0.015% was detection rate with pap smear.
Conclusion: Cervical Cancer screening in large scale in low-resource setting is feasible in India by both pap smear and VIA/VILI.
Department of Obstetrics and Gynaecology, Federal Medical CenterBirnin-Kebbi, Kebbi State, Nigeria, End Cervical Cancer Nigeria Initiative, Birnin Kebbi, Nigeria, Department of Pathology, Federal Medical Center, Birnin Kebbi, Nigeria, Cephas Health Research Initiative, Ibadan, Nigeria. MEDBOOM Empire, Lagos, Nigeria.
Background: Cervical cancer is a disease of inequality, with low-resource settings bearing the highest burden of the disease. More than 80% of new cases and 90% of cervical cancer-related deaths occur in low-resource settings. Cervical cancer patients in low-resource settings typically present late; hence, the observed high case-fatality ratio. Understanding the factors responsible for the late presentation will inform evidence-based planning of interventions to promote early diagnosis while advocating for national screening program to reduce the incidence.
Objective: To adopt best practices used in maternal mortality reduction strategies to cervical cancer prevention strategy in low-resource settings.
Methods: A multi-staged mixed methods study of factors responsible for late presentation of cervical cancer patients in Nigeria modelled on the well-documented reasons for maternal mortality in low-resource settings. A hypothetical clinical course of a typical patient presenting late at Federal Medical Centre, Birnin-Kebbi, was constructed using combined history of –patients with confirmed cases of cervical cancer that presented to the hospital from January 2020 to January 2021. Factors causing late presentation were listed and were modelled using the delay concept of maternal motility.
Results: There are striking similarities between the factors causing late presentation of cervical cancer patients and causes of maternal mortality in low-resource settings. Both are preventable, associated with low socio-economic status, related to inequality in access to quality healthcare and have evidence-based preventive interventions. Also, these interventions have successfully been implemented in developed countries while developing countries have not been able to take advantage of these proven interventions to reduce their burden of these conditions.
Conclusion: The causes of late presentation of cervical cancer patients can be categorized into the delay model of causes of maternal mortality with potential of promoting better understanding of causes of late presentation of cervical cancer patients in low-resource settings. This knowledge can be applied to downstage cervical cancer thereby improving clinical outcome of management in low-resource settings.
Raja Rajeshwari Medical College and Hospital, Bengaluru, India
Objectives: To calculate the accuracy of Pap smear, VIA, VILI in detecting precancerous lesions of cervix, reference standard being biopsy cervix. The objective was to calculate the sensitivity, specificity, positive predictive value, negative predictive value of these tests and compare the results.
Methods: This cross-sectional study for a period of 18 months was carried out at Raja Rajeshwari Medical College and Hospital, Bengaluru for a sample size of 100. Cervix was closely inspected for macroscopic abnormalities. Pap smear was taken, and then visual inspection using 5% acetic acid was done. After VIA, Lugol’s iodine was applied to the cervix and naked eye examination was done. Careful examination of cervix and the transformation zone was carried out. All women were subjected for colposcopy-directed biopsy and HPE. Colposcopy-directed biopsy result was taken as gold standard. The results of Pap smear were compared with VIA and VILI findings taking colposcopy-directed biopsy as gold standard.
Results: The sensitivity calculated for visual inspection methods was 100% and specificity 62.5%, positive predictive value 10% and negative predictive value 100%. The sensitivity for Pap smear in this study was 75%, specificity 96.8%, positive predictive value 50% and negative predictive value 98.9%.
Conclusion: Sensitivity for visual inspection studies was greater than that of Pap smear. Thus, in a low-resource country like ours where adequate number of cytologists and facilities are not available, visual Inspection with Acetic acid and Lugol’s iodine can be used as an effective screening technique for cervical cancer.
Department of Obstetrics & Gynaecology, KGMU, Lucknow, India
Background: Lack of availability and high cost of cytology, primary HPV-based screening has led WHO, to recommend VIA and VILI for screening of cervical cancer in poor resource settings.
Methods: 210 women were screened with VIA, VILI in camp setting in remote area of Uttar Pradesh. Demographics details, awareness of women about cervical cancer and barriers for screening were recorded. Sensitivity, specificity and positive predictive value of each test calculated.
Results: Out of 210 women screened, 29 (13.81%) were VIA positive, and remaining 181 women (86.19%) had normal VIA,24 patients (11.43%) were VILI positive and remaining 186 women (88.57%) had normal VILI. Screen positives were called at tertiary care for Colposcopy and if required biopsy. Of the 29 VIA-positive cases, 16 (55.17%) had CIN on HPE 3 (15.79%) patients who had negative VIA but positive on VILI were reported to have positive HPE. Of the 24 VILI-positive cases, 17 (i.e., 70.83%) had CIN on HPE and 2 cases (10.53%) that were missed on VILI but positive on VIA had positive HPE. The sensitivity, specificity, positive predictive value and negative predictive value for VIA (84.20%, 55.20%, 55.2%, 84.20%), VILI (89.5%,75.9%,70.80%,91.7%). 83% women were not aware about cervical cancer and its sign and symptoms,79% reported lack of awareness, availability as barrier to screening and 63%reported fear and anxiety as barrier to screening.
Conclusions: In a resource-constrainted setting VIA and VILI can prove a very helpful tool for screening and simultaneously it gives opportunity to interact with underprivileged women and impart information, Education and Counselling about cervical cancer and its prevention.
Department of Obstetrics and Gynaecology, J.N.MC.H, Aligarh, India
Introduction: Worldwide, cervical cancer is the fourth most common cancer in women.80% of the cases are from the developing countries. Various alternative strategies such as unaided visual inspections of the cervix after the application of 3–5% acetic acid (VIA) and visual inspection after the application of Lugol’s iodine (VILI) have been developed for screening in developing countries. However, the efficacy of these methods is in the presence of genital infection needs to be evaluated.
Objectives: To compare the sensitivity, specificity, positive predictive value, negative predict value of Per speculum examination, VIA, VILI, Pap smear in detecting premalignant and malignant lesions of cervix in the presence of infection.
Methods: This was a cross-sectional, comparative study in which 330 patients attending gynaecological OPD were enrolled. Per speculum examination, cervical swab for culture followed by Pap smear, VIA, VILI was done. Colposcopy and biopsy confirmation was done if tested positive by any of the above methods.
Results: Of the 330 patients, 132 (40%) patients had cervical culture positive. Among the culture positive 122 (92.4%) had positive per speculum, 21 (15.9%) had positive Pap test, 36 (27.2%) had positive VIA and 38 (27.9%) had VILI positive. On biopsy 17 had CIN, 2 had squamous cell carcinoma. Sensitivity, specificity, positive predictive value and negative predictive value of Per speculum was 78.9%, 5.3%, 12.5%, 60%, respectively, for Pap they were 73.5%, 93.8%, 70%, 95.4%, respectively, for VIA they were 78.94%, 81.41%, 41.6%, 95.8%, respectively, and for VILI they were 78.94%,80.53%, 40.54%, 95.8%, respectively.
Conclusions: VIA and VILI are effective screening tests even in the presence of genital infection.
Bhandara, Maharashtra, India
India is a country with large variation in social, religious, cultural and resource access.
However, due to the intimate nature of the examinations and due to the cost involved, many candidates refuse screening in spite of the wide prevalence.
It requires a coordinated multidisciplinary approach involving primary healthcare workers, nurses, ASHA workers and doctors. The costs can be reduced and the sensitivity of testing improved by an algorithm that combines the use of LBC with HPV DNA detection and confirmation of type with PCR where required.
Department of Obstetrics and Gynaecology, All India Institute of Medical Sciences New Delhi
Objective: To assess factors affecting participation and outcomes of a second round of cervical cancer screening.
Design: Cohort study.
Methods: Women aged 30–59 years from a semi-urban area of Delhi who had been screened with cytology, HPV testing (HC2) and VIA were recalled for screening with HPV and VIA after 5 years. Their awareness about cervical cancer was assessed at both times.
Results: Of 1007 women screened during round-1, 133 (13.9%) women were screen positive on any test: cytology ≥ ASCUS, 54 (5.3%); VIA +, 50 (4.9%); HPV+, 54 (5.3%). CIN1, CIN2 and CIN3 lesions were found in 18, 3 and 5 women, respectively. Among CIN2/3 cases, 6/8 were detected by HPV test, 3/8 by cytology and 2/8 by VIA. All received treatment as per standard-of-care. Five years later, only 714 (70.9%) women were still available for round-2 screening, of whom 298 (41.7%) declined participation: on duty (n = 144), said repeat screening is not required (n = 102), husband refused (n = 8), no reason (n = 44). In round-2, 61 (14.6%) women were screen-positive on any test; VIA + , 49 (11.7%); HPV + , 24 (5.7%). Of 133 screen-positive women of round-1, only 43 (32.3%) underwent screening. Of previously diagnosed CIN1 and CIN2/3, only 4/18 and 4/8 participated in screening, only one was found to have CIN1. New CIN3 lesions were diagnosed in 2 women in round-2, both were positive on VIA and HPV.
Conclusions: Repeated rounds of screening are not feasible or acceptable. A single round of screening with primary HPV testing will be the most effective screening strategy.

Conclusion: Cervical Cancer screening in large scale in low-resource setting is feasible in India by both Pap smear and VIA/VILI.
Department of Gynaecological oncology, Chittaranjan National Cancer Institute, Kolkata, India
Objectives: The strategies to prevent cervical cancer should be country specific, affordable and feasible in the population. The community-based project primarily assessed the utility of “Screen and Treat” strategy by using low-cost VIA method with 5% acetic acid and /or HPV DNA detection test. Secondary objective was to evaluate the response and compliance of the participants.
Methods: A prospective study (approved by Institutional Ethics Committee) was conducted by the Department of Gynaecological Oncology, Chittaranjan National Cancer Institute (CNCI) from January 2016 to April 2017. Eligible women were tested for HPV DNA test and/or by VIA with 5% acetic acid. VIA positive women were treated by either Cryotherapy or thermal ablation following a punch biopsy at same visit. Rest were referred to CNCI for excision. The HPV-positive women were recalled for VIA followed by biopsy and treatment. The results were analysed by Stata version 14.
Results : A total number of 6592 women were recruited with 4.96% VIA positive and 4.24% HPV DNA positive. Colposcopy and biopsy followed by treatment was done in 82.1% women. Acceptability of Thermal ablation was higher than Cryotherapy with less pain (3.1% vs 6.6%). Women who were exposed to unnecessary treatment was 61.9%. Only 43.1% women had their follow-up.
Conclusion: In a resource-constrained setup, utilisation of available resources with cost-effective strategies like “Screen and Treat” can help to reduce the burden of cervical neoplasia with increased chances of overtreatment.
Department of Gynaecological Oncology, Chittaranjan National Cancer Institute, Kolkata, India
Objective: Paucity of resources and trained professionals makes it difficult to implement a cervical cancer screening program in India. This study aims to evaluate the feasibility of self-sampling for detection of human papillomavirus (HPV) DNA in a community-based cervical cancer screening project.
Methods: Women (30–60 years) were assigned to do self-sampling or get their samples collected by healthcare workers in outreach clinics. The samples were brought to the institute and were tested by hybrid capture2 (HC2) test for 13 high-risk HPV types. HC2 positive women were brought to the institute where they underwent colposcopy, biopsy and treatment by Thermal ablation, Cryotherapy or Loop Electrosurgical Excision Procedure (LEEP). A focussed group discussion was done with health workers involved with this project in the form of a questionnaire.
Results: From May 2017 and December 2020, 15,311 women were recruited. Amongst them, 4916 (32.1%) had self-sampling and 10,395 (67.9%) had health-worker collected sample. The HC2 positivity rates in both groups were 269 (5.5%) and 652 (6.3%), which was not significantly different statistically (P = 0.06). The colposcopy rates and Cervical Intraepithelial Neoplasia (CIN) 2 and 3 detection rates were also similar. All women were comfortable with self-sampling with no sample inadequacy or wastage of collection kits. The health workers rated both procedures as acceptable. The advantage of self-sampling was that no examining table or light source was required and the screened women were less “shy” while sample collection.
Conclusion: Self-sampling for HPV may increase participation in cervical cancer screening programs, especially in the COVID19 era.
Gombe State University/ Federal Teaching Hospital, Gombe, Nigeria
Background : Cervical cancer is the second most common cancer in women in Sub Saharan Africa with 570,000 women diagnosed with cervical cancer in 2018. Eighty-five percent of these occur in low and middle-income countries, with 311,000 women dying from the disease worldwide. Nigeria has recorded a 5-year prevalence of 21.6% with 10,000 new cases and 8,000 deaths annually. With the launch of the WHO Global Strategy to Accelerate the Elimination of Cervical Cancer in November 2020, it became pertinent to employ the use of screen and treat with Visual inspection with acetic acid and Lugol’s iodine (VIA/VILI) in low-resource setting. Perhaps successful implementation of wide screening and treatment of precancerous lesions could reduce the number of new cases of the disease and related deaths in Gombe.
Aim: To determine the prevalence of VIA/VILI positive cervical lesions among 1000 women screened for cervical precancer lesions in Gombe.
Methods : This was a cross-sectional study of women who attended the free cervical precancer screening with VIA/VILI in Gombe from 11 th of January, 2021 to 10 th of February, 2021 at Federal Teaching Hospital Gombe.
Results : One thousand women had speculum examination of the vagina and 954 women had visual inspection of the cervix with acetic acid ± Lugol’s iodine. Of these 222 (22.3%) women had VIA/VILI positive lesions of the cervix. Three women had frank invasive carcinoma of the cervix. The age range was between 30–80 years. The mean age was 40.35 years ± 8.28 years. The mean parity was 3.74 ± 2.98 children. The average age at coitarche was 20.97 ± 5.32 years.
Conclusion : VIA/VILI positive lesions of the cervix are quite common among women 30 years and above in Gombe and implementation of screening with “See and treat” can reduce cervical cancer incidence and its mortality.
