Abstract
Forty-three adult patients with locally advanced or metastatic soft tissue sarcoma entered a pilot study of combination chemotherapy comprising 50 mg of doxorubicin/m2 by intravenous bolus, 850 mg of dacarbazine/m2 by 1-hour infusion, and 5 g of ifosfamide/m2 by 24-hour infusion with mesna uro-protection. The overall response rate in 40 assessable patients was 25% with two complete remissions. Twenty-four episodes of infection occurred in 148 courses (16%). These infections were usually associated with neutropenia (granulocyte count 9/L), which occurred in 70% of the courses. These results do not differ from those elicited by each agent alone, and may reflect inadequacies of dose intensity or scheduling, or evaluation in a study population with adverse prognostic factors.
