Abstract

Abstract: Objective: To identify factors predictive of poor prognosis in women with stage III nonserous epithelial ovarian cancer (EOC) who had undergone maximal or optimal primary cytoreductive surgery (CRS) followed by six cycles of intravenous carboplatin/paclitaxel chemotherapy. Methods: A multicenter, retrospective department database review was performed to identify patients with stage III nonserous EOC who had undergone maximal or optimal primary CRS followed by six cycles of carboplatin/paclitaxel chemotherapy at seven gynecological oncology centers in Turkey. Demographic, clinicopathological and survival data were collected. Results: A total of 218 women met the inclusion criteria. Of these, 64 (29.4%) patients had endometrioid, 61 (28%) had mucinous, 54 (24.8%) had clear‐cell and 39 (17.9%) had mixed epithelial tumors. Fifty‐five (25.2%) patients underwent maximal CRS, whereas 163 (74.8%) had optimal debulking. With a median follow‐up of 31.5 months, the 5‐year progression‐free survival (PFS) and overall survival (OS) rates were 34.8% and 44.2%, respectively. Bilaterality (hazard ratio [HR] 1.44, 95% CI 1.01–2.056; P = 0.04), age (HR 2.25, 95% CI 1.176–4.323; P = 0.014) and maximal cytoreduction (HR 0.34, 95% CI 0.202–0.58; P < 0.001) were found to be independent prognostic factors for PFS. However, age (HR 2.6, 95% CI 1.215–5.591; P = 0.014) and maximal cytoreduction (HR 0.31, 95% CI 0.166–0.615; P < 0.001) were defined as independent prognostic factors for OS. Conclusion: The extent of CRS seems to be the only modifiable prognostic factor associated with stage III nonserous EOC. Complete cytoreduction to no gross residual disease should be the main goal of management in these women.
