PURPOSE:: Given the potential for improved outcomes, a phase I trial was initiated to develop a paclitaxel/cisplatin regimen that could be delivered every two weeks to women with newly diagnosed advanced ovarian cancer.
PATIENTS AND METHODS:: From 1992 to 1994, 29 (28 eligible) patients were enrolled in a dose-seeking trial. All received 60 mg/m2 of cisplatin preceded by paclitaxel infused over three hours. The paclitaxel dose was excalated from an initial level of 90 mg/m2 by 10 mg/m2 increments in successive cohorts of patients.
RESULTS:: At 120 mg/m2 of paclitaxel, the dose-limiting toxicity was granulocytopenia which prevented retreatment on time. The recommended dose level was therefore paclitaxel 110 mg/m2 infused over three hours with cisplatin 60 mg/m2, repeated bi-weekly for eight cycles.
CONCLUSION:: This bi-weekly schedule of paclitaxel/cisplatin provides no advantage in terms of dose-intensity nor total dose of paclitaxel in comparison to more common regimens given tri-weekly.
