Clinical Presentation of Endometrioid Epithelial Ovarian Cancer with Concurrent Endometriosis: A Multicenter Retrospective Study

Abstract

In this large series of patients with EEOC, the main presenting symptoms were pelvic pain followed by gastrointestinal symptoms, palpable mass, abdominal distension, vaginal bleeding, and newly developed or exacerbated dysmenorrhea and dyspareunia. Dyspareunia and dysmenorrhea were more frequently detected in patients with endometriosis. Normal CA-125 levels cannot be applied as a marker to exclude EEOC, particularly at the early stages.
