24 patients with advanced epithelial ovarian cancer, who demonstrated a clinical complete or partial response to the induction of intravenous chemotherapy, underwent implantation of a subcutaneous semipermanent port-and-catheter system (Port-A-Cath) for intraperitoneal chemotherapy, which consisted of carboplatin 300 mg/m2 every 4 weeks. The median survival was 27.4 months for minimal residual disease versus 8 months for bulky disease (p = 0.0054). The median progression-free interval was 15.7 months for minimal residual disease versus 1.8 months for bulky disease (p = 0.008). There were 3 complications (12.5%) related to the catheter: 1 perforation of the large bowel and 2 catheter inflow obstructions. Myelosuppression, especially a grade 3 leucopenia in 5 patients (25%) and a grade 4 thrombopenia in 3 patients (15%), was the dose-limiting toxicity. Even with maximum cytoreductive surgery and second-line intraperitoneal carboplatin-based chemotherapy, the 5-year progression-free survival (4.1%) remains very small.
