BACKGROUND: The purpose of this study was to evaluate the incidence rate of endometrial disease, particularly endometrial carcinoma, in patients with primary peritoneal serous papillary carcinoma (PSPC). METHODS: Retrospective review of clinical and histological data from 32 women undergoing surgery (with hysterectomy) for stage III or IV PSPC. RESULTS: Six patients underwent primary debulking surgery and 26 underwent interval debulking surgery after 3 or 4 courses of platinum-based chemotherapy. Six patients (18%) had endometrial disease (hyperplasia in four). Two patients had endometrioid adenocarcinoma of the uterine body (stage IA grade 1 in one case, and stage IB grade 1 in the other) associated with the PSPC. CONCLUSIONS: Endometrial carcinoma of the uterine body may be associated with PSPC (6% cases in the present series). This result suggests that systematic hysterectomy should be performed at the time of debulking surgery in PSPC, even in the absence of peritoneal spread within pelvic cavity.
