A phase II trial of ifosfamide and mesna in patients with advanced or recurrent mixed mesodermal tumors of the ovary previously treated with platinum-based chemotherapy: a Gynecologic Oncology Group study.
A phase II trial of ifosfamide and mesna in women with mixed mesodermal tumors of the ovary who had previously received platinum-containing chemotherapy was conducted by the Gynecologic Oncology Group (GOG). The starting dose of ifosfamide was 1.2 g/m2 daily iv for 5 days. Mesna was given intravenously with and at 4 and 8 hr following the administration of ifosfamide. Each dose of mesna was 20% of the total daily dose of ifosfamide. Thirty-two patients were placed on the study; 31 were evaluable for toxicity and 28 for response. Twenty-seven patients (87.1%) had previously undergone surgery and three (9.3%) had received radiotherapy before this trial. GOG grade 3 or 4 granulocytopenia occurred in 11 (35.5%) patients, and one (3.2%) developed grade 4 thrombocytopenia. Two patients (6.4%) had grade 3 neurotoxicity. A complete response was observed in one patient (3.6%) and partial responses in four patients (14.3%) for a total response rate of 17.9% (95% confidence interval = 6.1-36.9%). In conclusion, ifosfamide has activity in previously mixed mesodermal tumors of the ovary.
