Abstract

Despite the best standard treatment, optimal cytoreductive surgery (CRS) and platinum/taxane-based chemotherapy, prognosis of advanced epithelial ovarian carcinoma (EOC) remains poor. Recently, CRS plus hyperthermic intraperitoneal chemotherapy (HIPEC) has been developed to treat peritoneal carcinomatosis (PC). This study was to evaluate the efficacy and safety of CRS+HIPEC to treat PC from advanced/recurrent EOC. METHODS: Forty-six PC patients from advanced EOC (group A) or recurrent EOC (group B) were treated by 50 CRS+HIPEC procedures. The primary endpoints were progression-free survival (PFS) and overall survival (OS); the secondary endpoints were safety profiles. RESULTS: The median OS was 74.0 months[95% confidence interval (CI) 8.5-139.5] for group A versus 57.5 months (95% CI 29.8-85.2) for group B (P = .68). The median PFS was not reached for group A versus 8.5 months (95% CI 0-17.5) for group B (P = .034). Better median OS correlated with peritoneal cancer index (PCI) b 20 (76.6 months for PCI ≤ 20 group vs 38.5 months for PCI N 20 group, P = .01), complete cyroreduction (residual disease ≤ 2.5 mm)[79.5 months for completeness of cytoreduction (CC) score 0-1 vs 24.3 months for CC 2-3, P = .00], and sensitivity to platinum (65.3 months for platinum-sensitive group vs 20.0 for platinum-resistant group, P = .05). Serious adverse events occurred in five patients (10.0%). Multivariate analysis identified CC score as the only independent factor for better survival. CONCLUSION: For advanced/ recurrent EOC, CRS+HIPEC could improve OS with acceptable safety.
