Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy for First Relapse of Ovarian Cancer.

Background: To assess impact of surgery and hyperthermic intraperitoneal chemotherapy (HIPEC) in patients treated for a first relapse of ovarian cancer (FROC).

Patients And Methods: Patients with a FROC treated with second-line chemotherapy, surgery and HIPEC were retrospectively included from 13 Institutions. Studied parameters were interval free between the end of initial treatment and the first relapse, second-line chemotherapy, peritoneal cancer index and completeness of surgery, HIPEC, mortality and morbidity, pathological results and survival.

Results: From 2001 to 2010, 314 patients were included. The main strategy was secondary chemotherapy followed by surgery and HIPEC (269/314-85.6%). Mortality and morbidity rates were respectively 1% and 30.9%. Median follow-up was 50 months, 5-year overall survival was 38.0%, with no difference between platinum-sensitive or -resistant patients and 5-year disease-free survival was 14%.

Conclusion: HIPEC allows encouraging survival in the treatment of FROC, better in case of complete surgery, with acceptable mortality and morbidity rates.
