Abstract

Objective. Because of preliminary observations favoring the use of mitomycin, doxorubicin, and cisplatin (MAP) chemotherapy in leiomyosarcomas, the Gynecologic Oncology Group (GOG) decided to conduct a phase II clinical trial of this combination regimen in patients with advanced disease. Methods. Patients with histologically confirmed uterine leiomyosarcoma who had not previously received cytotoxic drugs were considered for participation in this clinical trial. Eligible patients had measurable disease, GOG performance status 0-2, and adequate bone marrow, renal, and hepatic function according to standard criteria. Mitomycin 8 mg/m2 and doxorubicin 40 mg/m2 were each given by iv injection followed immediately by cisplatin 60 mg/m2 in 1 liter of 0.45% saline plus mannitol 25 g. Patients who remained free from tumor progression or intolerable toxicity received at least three, to a maximum of six, cycles of MAP. Results. Forty-one patients were registered, of whom 4 were determined ineligible (wrong cell type, 2; wrong site of origin, 1; inadequate pathology material, 1). Thirty-five of the 37 were evaluable for response after receiving from one to six (median three) cycles of MAP. Three patients (9%) achieved a complete response and 5 (14%) exhibited a partial response. The most common adverse effects were leukopenia (33 patients) and thrombocytopenia (30 patients). Pulmonary toxicity was seen in 10 patients and was a factor in the clinical deterioration and death of 2. Conclusions. MAP is active against advanced uterine leiomyosarcomas, but not remarkably so. Despite its low therapeutic index, this novel, possibly interactive, combination may serve as a forerunner to regimens that more efficiently exploit the enhancement of sarcoma cell kill under hypoxic conditions.
