Cytoreductive Surgery Combined with Hyperthermic Intraperitoneal Intraoperative Chemotherapy in the Treatment of Advanced Epithelial Ovarian Cancer

Background/Aims. Intraperitoneal intraoperative hyperthermic chemotherapy (HIPEC) has been used in the treatment of ovarian cancer. The purpose of the study is to determine the efficacy of HIPEC after cytoreductive surgery in advanced ovarian cancer. Patients/Methods. From 2006 to 2010 patients with advanced ovarian cancer were enrolled in a prospective nonrandomized study to undergo cytoreductive surgery combined with HIPEC. Clinical and histopathological variables were correlated to hospital mortality, morbidity, survival, and recurrences. Results. The mean age of 43 women was 59.9±13.8 (16–82) years. The hospital mortality and morbidity rate were 4.7% and 51.2%, respectively. Complete cytoreduction was possible in 69.8%. The overall 5-year survival rate was 54%. The prognostic indicators of survival were the extent of prior surgery (=0.048) and the extent of peritoneal dissemination (=0.011). The recurrence rate was 30.2%. Conclusions. Maximal cytoreductive surgery combined with HIPEC is a well-tolerated, feasible, and promising method of treatment in advanced ovarian cancer.
