    Abstract:
    BACKGROUND: Limited data are available on the use of cytoreductive surgery with hyperthermic intraperitoneal chemoperfusion (HIPEC) in patients with recurrent stage III ovarian cancer. METHODS: Patients with recurrent, heavily pretreated ovarian cancer were enrolled onto a phase II multimodal protocol consisting of extensive cytoreduction followed by HIPEC. RESULTS: Forty-two women were treated from October 2002 until January 2009. Chemoperfusion was performed with cisplatin in 59% and oxaliplatin in 41% of patients. A macroscopically complete resection was achieved in 50% of patients. No mortality occurred, and the major morbidity rate was 21%. After a mean follow-up of 21 months, median overall survival (OS) was 37 months (95% confidence interval 12.2-61.8) and median progression-free survival was 13 months (95% confidence interval 6.9-19.1). In univariate analysis, OS was influenced by completeness of cytoreduction, type of chemoperfusion drug, nodal status, and tumor grade. In a Cox regression model, only completeness of cytoreduction (hazard ratio 0.06-0.8, P=.022) and tumor grade (hazard ratio 1.23-12.6, P=.021) were independent predictors of OS. CONCLUSIONS: In selected patients with heavily pretreated recurrent ovarian cancer, cytoreduction combined with HIPEC may provide a meaningful OS with acceptable morbidity. Optimal results are achieved in patients with a macroscopically complete resection and biologically favorable disease.
