Abstract

Objectives.: To determine a recommended dose level (RDL) of paclitaxel, cisplatin and topotecan in women with previously untreated epithelial ovarian or peritoneal cancer as a possible experimental arm in a future Gynecologic Oncology Group phase III study. Methods.: Patients with newly diagnosed stage III or IV disease were treated with paclitaxel 175 mg/m2/3 h, followed 2 h later by cisplatin 50 mg/m2 on day 1. Topotecan was administered on consecutive days as a 30-minute infusion, beginning after cisplatin on day 1, receiving either 5 days beginning at 0.3 mg/m2 (cohort 1), or 3 days beginning at 0.5 mg/m2 (cohort 2). Treatment was given every 21 days for a maximum of 8 cycles. Results.: Forty-five evaluable patients were enrolled in the two cohorts. Thrombocytopenia and prolonged neutropenia were the major dose-limiting toxicities. Dose-limiting neutropenia was seen at the first dose level, thus all subsequent dose escalations included Filgrastim. The RDL of cohort 1 was paclitaxel 175 mg/m2/3 h, cisplatin 50 mg/m2 and topotecan 0.5 mg/m2 daily × 5 with Filgrastim. The RDL of cohort 2 was paclitaxel 175 mg/m2/3 h, cisplatin 50 mg/m2 and topotecan 0.75 mg/m2 daily × 3 with Filgrastim. Conclusion.: In women with previously untreated epithelial ovarian or peritoneal cancer the combination of paclitaxel, cisplatin and topotecan is feasible. However, this treatment requires the use of Filgrastim and attenuated dosing of topotecan in both a 5-day and 3-day topotecan infusion schedule.
