Aims and background: The optimal salvage therapy for recurrent ovarian carcinoma has not been clearly established. Response to second-line chemotherapy is low, with a short median survival (8.8-15 months). We investigated the effect of an aggressive approach consisting of surgery followed by intraperitoneal drug delivery and local hyperthermia. Patients and methods: In a phase II clinical study, 27 patients with advanced/recurrent ovarian carcinoma were treated with cytoreductive surgery and intraperitoneal hyperthermic perfusion. Median patient age was 53 years (range, 30-67) and mean follow-up was 17.4 months (range, 0.3-36.0). Patients had been surgically staged and heavily pretreated with cisplatin-based, taxol-based or taxol/platinum-containing regimens. Nineteen (70%) patients were cytoreduced to minimal residual disease <2.5 mm. The intraperitoneal hyperthermic perfusion was performed with the closed abdomen technique, using a preheated polysaline perfusate containing cisplatin (25 mg/m2/L) + mitomycin C (3.3 mg/m2/L) through a heartlung pump (mean flow of 700 mL/min) for 60 min in the hyperthermic phase (42.5 °C). Results: Two-year overall survival was 55%. Median times to overall progression and local progression were 16 months and 21.8 months, respectively. Variables that affected the overall survival or time to progression were as follows: residual disease (P = 0.00025), patient age (P = 0.04), and lag time between diagnosis and cytoreductive surgery + intraperitoneal hyperthermic perfusion (P = 0.04). Treatment-related morbidity, mortality and acute toxicity (grade II-III) rates were 11%, 4% and 11%, respectively. Eight (89%) of 9 patients had ascites resolution. Conclusion: Our results suggest that cytoreductive surgery + intraperitoneal hyperthermic perfusion is a well-tolerated, feasible and promising alternative in the management of selected patients with recurrent ovarian cancer, but further randomized controlled studies are needed in order to confirm our findings.
