High-grade carcinomas affecting the ovary or peritoneum may originate from the epithelium of the fallopian tubes. Whilst gynecological cancers are more frequent in post-menopausal patients, 12.1% of ovarian malignancies are diagnosed in pat…

Primary vaginal cancer is a rare malignant tumor; its pathogenesis remains unclear and only a limited number of cases have been documented in the literature. The present report outlines a rare case of primary vaginal endometrioid adenocarci…

Epithelial ovarian cancer (EOC) is a leading cause of mortality among gynecological malignancies, predominantly due to late-stage diagnoses and complex management challenges. Traditional treatment strategies, primarily centered on extensive…

Although ovarian endometrioid carcinoma (OEC), frequently associated with endometrial endometrioid carcinoma (EEC), is often diagnosed at an early stage, the prognosis remains poor. The development of new, effective drugs to target these ca…

Immune escape is a phenomenon in which tumor cells or infections evade detection and clearance by the host immune system in various ways. During an antitumor immune response, cells increase the concentration of pentameric stalk, which enhan…

Skin cutaneous melanoma (SKCM) is a highly aggressive malignancy, and understanding the mechanisms underlying its metastasis is essential for improving patient prognosis. N6-methyladenosine (m6A) RNA modification is involved in tumor progre…

Retroperitoneal squamous cell carcinoma (SCC) is an extremely rare tumor originating from the retroperitoneum, with an unclear etiology and origin. Imaging studies are the preferred diagnostic modality for retroperitoneal tumors. The presen…

High-grade serous ovarian carcinoma (HGSOC), an epithelial ovarian carcinoma, is primarily believed to originate from fallopian tube epithelial cells. This site of origin facilitates the dissemination of tumor cells to retroperitoneal organ…

Ovarian cancer is the most lethal malignancy among female genital cancers, primarily due to the non-specific symptoms, late-stage diagnosis and poor prognosis. Thus, there is a need for accurate and precise diagnostic methods to improve ove…

Ovarian cancer (OC) presents a global health challenge, with well-documented genetic aspects. However, to the best of our knowledge, the role of human papillomavirus (HPV) types 16 and 18 in OC remains unclear. The present meta-analysis ass…

Endometriosis-associated adenocarcinoma of the rectum is rare and is usually misdiagnosed as colorectal carcinoma or other gynecological tumors. In the current report, the clinicopathological features of endometriosis-associated adenocarcin…

Tissue factor pathway inhibitor-2 (TFPI2) is a tumor marker for diagnosing ovarian cancer and ovarian clear cell carcinoma (OCCC); however, its effectiveness as a prognostic marker remains unclear. The present study aimed to investigate the…

Ovarian cancer is a malignant tumor that seriously endangers health. Early ovarian cancer symptoms are frequently challenging to detect, resulting in a large proportion of patients reaching an advanced stage when diagnosed. Conventional dia…

Lymphovascular space invasion (LVSI) is considered to be a poor prognostic factor in endometrial cancer. However, management of patients with early-stage endometrial cancer with positive LVSI remains controversial. The main objective of the…

The incidence of adenocarcinoma-in-situ (AIS) of the uterine cervix is rising, with invasive adenocarcinoma becoming increasingly common relative to squamous cell carcinoma. The present study reviewed a cohort of 84 patients first-time trea…

Gastric cancer is a common tumor of the digestive system, which can occur in any part of the stomach. Kallikrein 6 (KLK6) is a trypsin-like serine protease and has been found to be involved in extracellular matrix remodeling, tumor invasion…

Endometrial carcinoma (EC) is one of the most common malignant gynecological tumors. Dysregulation of microRNAs (miRNAs/miRs) is frequently identified in human tumors, playing key regulatory roles in tumor growth and metastasis. The present…

Endometrial cancer (EC) is a multi-factorial disease of which pathogenesis has not been fully elucidated. The function and underlying mechanism of microRNA-20a-5p (miR-20a-5p) in EC remain poorly understood. The present study aimed to analy…

Gynecological cancers, including breast, ovarian, uterine, vaginal, cervical and vulvar cancers are among the major threats to modern life, particularly to female health. Long non-coding RNAs (lncRNAs) play critical roles in normal developm…

Endocrine-disrupting chemicals (EDCs) are exogenous chemical compounds ubiquitously found in everyday life of the modern world. EDCs enter the human body where they act similarly to endogenous hormones, altering the functions of the endocri…

Ovarian cancer survival is poor, in part, because there are no specific biomarkers for early diagnosis. C-Mannosyl tryptophan (CMW) is a structurally unique glycosylated amino acid recently identified as a novel biomarker of renal dysfuncti…

The present study aimed to compare the accuracy of the Risk of Ovarian Malignancy Algorithm (ROMA) and cancer antigen (CA)125 to discriminate between benign ovarian tumors and early-stage ovarian cancer according to imaging tumor subtypes a…

The aim of the present study was to examine the association between plasma heavy metals and the metabolome in patients with breast cancer (BC), and the association with cancer development. Nuclear magnetic resonance was used to determine th…

Patients with cervical adenocarcinoma (AC) and adenosquamous carcinoma (ASC) have a poorer prognosis than those with squamous cell carcinoma (SCC). Erb-b2 receptor tyrosine kinase 3 (HER3) is a member of the epidermal growth factor receptor…

Chronic hyperinsulinemia due to insulin resistance and elevated levels of insulin-like growth factor (IGF)-1 and IGF-2 are suggestive of a significantly higher risk of endometrial carcinoma. There is a wealth of evidence showing differentia…
