BACKGROUND: Endometriosis is associated with an increased risk of type I ovarian cancer, yet the prognostic relevance of concurrent endometriosis at diagnosis remains unclear. This cohort study evaluated whether endometriosis independently …

BACKGROUND: Numerous studies have explored the histological overlap between endometrial carcinoma and adenomyosis, yet the clinical implications of their co-occurrence remain ambiguous. This study aims to evaluate the impact of adenomyosis …

BACKGROUND: The impact of the presence of adenomyosis on survival in patients with non-endometrioid endometrial cancer (EC) remains unclear. The aim of this study is to compare the effect of the presence or absence of histologically proven …

BACKGROUND: The diagnosis of rare uterine leiomyosarcoma (uLMS) remains a challenge given the high incidence rates of benign uterine tumors such as leiomyoma (LM). In the last decade, several clinical scores and blood serum markers have bee…

PURPOSE: To assess the clinical characteristics and the risk factors related to the unfavorable prognosis of endometrioid ovarian carcinoma (EOVC) based on data from the Surveillance, Epidemiology, and End Results (SEER) database and two cl…

Abstract Background The main aim of this study was to establish the clinicopathological and prognostic correlations between endometriosis-associated and non-endometriosis-associated primary ovarian cancer, with a view to providing a referen…

BACKGROUND: To evaluate the diagnostic value of adding human epididymis protein 4 (HE4), cancer antigen 125 (CA125) and risk of malignancy algorithm (ROMA) to ultrasound for detecting ovarian cancer in patients with a pelvic mass. METHODS:…

BACKGROUND: Ovarian clear cell carcinoma (OCCC) is a special pathological type of epithelial ovarian carcinoma (EOC). We conducted this research to investigate the clinical characteristics and outcomes of OCCC and to provide additional supp…

BACKGROUND: Endometrial cancer (EC) is the most common malignancy of the female reproductive tract. Despite years of research, the accurate screening strategy is still not available in this disease and it is usually diagnosed only after the…

BACKGROUND: Somatic PTEN mutation occurs in a proportion of ovarian endometrioid carcinomas. However, these cancers have seldom been reported in diseases associated with germline PTEN variants, such as Cowden syndrome (CS). CASE PRESENTATIO…

BACKGROUND: Expression of Nodal, a member of the TGF-β superfamily, is commonly absent in differentiated tissues, while its re-expression occurs in a variety of human malignancy. However, little is known about its involvement in ovarian tum…

BACKGROUND: Endometriosis is a relatively common condition in women of reproductive age. Malignant transformation of intestinal endometriosis is a very rare event. We report a case in which a patient with a history of endometriosis underwen…

BACKGROUND: Laryngeal squamous cell carcinoma (LSCC) is the second most common cancer of the head and neck. In order to identify differentially expressed genes which may have a role in LSCC carcinogenesis, we performed GeneFishing Assay. On…

BACKGROUND: Extra-uterine mullerian adenosarcomas have varying biological behaviours depending on the presence of endometriosis or sarcomatous overgrowth. These behaviours manifest according to the tumours' histological characteristics and …

BACKGROUND: Intravenous leiomyomas are a rare variant of uterine leiomyoma. Although histologically benign, these tumors are associated with a poor prognosis due to propensity for metastasis, high recurrence rate, difficulty of obtaining co…

Background: No screening programs are available for ovarian or endometrial cancer. One reason for this is the low incidence of the conditions, resulting in low positive predictive values for tests, which are not very specific. One way of ad…

BACKGROUND: Medical research studies are becoming increasingly important for optimizing the prevention, diagnosis and treatment of illnesses. Participation in research studies can have many benefits for patients. In randomized and controlle…

BACKGROUND: Ovarian cancer is now recognized as a number of distinct diseases primarily defined by histological subtype. Both clear cell ovarian carcinomas (CCC) and ovarian endometrioid carcinomas (EC) may arise from endometriosis and freq…

BACKGROUND: Epidemiological evidence of relationships between endometriosis and epithelial ovarian cancer (EOC) has been obtained mainly from Western countries. Our goal was to determine the risk of EOC due to endometriosis in Taiwanese wom…

BACKGROUND: Epithelial ovarian cancer (EOC) is the most common cause of gynecological malignancy-related mortality. Ovarian clear cell carcinoma (CCC) has unique clinical characteristics and behaviors that differ from other histological typ…

BACKGROUND: Pituitary tumor-transforming gene (PTTG) is an oncogene that is overexpressed in variety of tumors and exhibits characteristics of a transforming gene. Previous transgenic mouse models to access the tumorigenic potential in the …

BACKGROUND: Malignant transformation of adenomyosis is a very rare event. Only about 30 cases of this occurrence have been documented till now. CASE PRESENTATION: The patient was a 57-year-old woman with a slightly enlarged uterus, who unde…
