Comparative Effectiveness of HIPEC Following Interval Debulking Surgery in Patients With Advanced-stage Ovarian Cancer

GOG 172 trial showed a dramatic improvement of overall survival in patients with stage III disease treated with intraperitoneal cisplatin and paclitaxel compared with those with intravenous administration. Currently, prospective cohort study showed a survival benefit of intraperitoneal chemotherapy compared with intravenous chemotherapy. Despite this improvement, intraperitoneal chemotherapy is not widely used as standard therapy owing to the high rate of adverse effects and inconvenience of administering therapy intraperitoneally. Hyperthermic intraperitoneal chemotherapy (HIPEC) is a multi-modal approach with combined intraperitoneal chemotherapy and hyperthermia. It maintains the theoretical benefit of intraperitoneal chemotherapy and reduces most of the adverse events from catheter-related problems with delivery of the chemotherapeutic agent at the end of surgery. In addition, hyperthermia increases the penetration of chemotherapy at the peritoneal surface and chemo-sensitivity. In this trial, we aim to evaluate the efficacy and safety of HIPEC procedures performed after interval debulking surgery in patients with advanced ovarian cancer.
