OBJECTIVES: The goal of this study was to evaluate the long-term outcome after consolidation intraperitoneal (IP) chemotherapy in patients with a negative second-look laparotomy (SLL) following first-line intravenous chemotherapy for advanced ovarian cancer. METHODS: This study included patients with FIGO stage III-IV ovarian cancer who entered into four prospective trials (1984-1995) including intravenous chemotherapy based on cisplatin (six cycles) and anthracycline, early debulking surgery after three cycles of chemotherapy in the case of initial residual disease >2 cm, SLL, and IP consolidation chemotherapy. Among 218 patients, 68 with biopsy-negative SLL received every 4 weeks three consolidation cycles of IP chemotherapy (mitoxantrone, cisplatin, etoposide) via a totally implantable port. Long-term outcome of these patients is reported. RESULTS: Mean age was 56 years (33-72 years). Overall, 51% of the patients had at least a grade 3 or 4 toxic effect. Main toxic effects were leukopenia, abdominal pain related to the catheter, and nausea and vomiting. Only 13 patients (19%) did not receive the full three cycles. The median progression-free survival (PFS) for the whole population is 34 months, 34% of the patients being estimated to be free of disease at 5 years. The median overall survival is 73 months, and the 5-year survival is 58%. CONCLUSIONS: In this selected population treated with IP consolidation chemotherapy, prolonged survival was observed. However, the occurrence of late relapses in this most favorable patient category underlines the need to improve the consolidation therapy options in ovarian cancer.
