OBJECTIVE: Many epithelial ovarian cancer (EOC) risk factors relate to sex hormones. The association between these factors and the expression of androgen receptor (AR), estrogen receptor-α (ER), and progesterone receptor (PR) in tumors is u…

Our objective was to test whether p53 expression status is associated with survival for women diagnosed with the most common ovarian carcinoma histotypes (high-grade serous carcinoma [HGSC], endometrioid carcinoma [EC], and clear cell carci…

In the 2016 WHO classification of genitourinary tumors Muellerian tumors of the urinary tract (MTUT) comprise clear cell adenocarcinomas and endometrioid carcinomas. Since these rare tumors remained understudied, we aimed to characterize th…

BACKGROUND: PTEN loss is a putative driver in histotypes of ovarian cancer (high-grade serous (HGSOC), endometrioid (ENOC), clear cell (CCOC), mucinous (MOC), low-grade serous (LGSOC)). We aimed to characterise PTEN expression as a biomarke…

OBJECTIVE: Several genetic variants have been validated as risk factors for ovarian cancer. Endometriosis has also been described as a risk factor for ovarian cancer. Identifying genetic risk factors that are common to the two diseases migh…

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…

CONTEXT: In the last two decades, a color based concept of disease activity in peritoneal endometriosis has been in use in the clinical context, with red lesions being considered active and black or white lesions being interpreted as less a…

Background: There is no screening program for ovarian or endometrial cancer. One way to address the problem could be the utilization of risk factors to define sub-populations with a higher incidence. Recently, there were hints that endometr…

OBJECTIVE: An incidental finding of atypical endometrial hyperplasia (AEH) in women who have undergone laparoscopic supracervical hysterectomy (LASH) is a rare phenomenon, and it is unclear whether laparoscopic extirpation of the cervical s…

Objective: The etiology of endometriosis is still a research field in which few consistent data are available. Large case-control studies or even cohort studies are rare, and most of the published data are conflicting. The aim of the presen…
