The objective of this phase II trial was to assess the therapeutic activity and toxicity of doxorubicin plus ifosfamide in previously untreated patients with advanced soft-tissue sarcoma. Treatment consisted of an intravenous bolus injection of doxorubicin at a dose of 50 mg/m2 followed by a 24-h infusion of ifosfamide at 5 g/m2 plus mesna, with therapy being repeated every 3 weeks until disease progression or unacceptable toxicity occurred. Of the 203 patients entered, 175 were evaluable for response. The overall response rate was 35% (95% confidence interval, 28%-42%), with 9% of patients achieving complete responses and 26% showing partial responses. The median time to progression was 29 weeks for all evaluable patients and 67, 40, and 28 weeks for complete and partial responders and patients with stable disease, respectively. The median duration of survival was 58 weeks. Myelosuppression was the dose-limiting toxicity, resulting in leukopenia (World Health Organization grades 3 and 4) in 73% of the evaluable patients. Other side effects were rare and usually well manageable.

Abstract

The objective of this phase II trial was to assess the therapeutic activity and toxicity of doxorubicin plus ifosfamide in previously untreated patients with advanced soft-tissue sarcoma. Treatment consisted of an intravenous bolus injection of doxorubicin at a dose of 50 mg/m2 followed by a 24-h infusion of ifosfamide at 5 g/m2 plus mesna, with therapy being repeated every 3 weeks until disease progression or unacceptable toxicity occurred. Of the 203 patients entered, 175 were evaluable for response. The overall response rate was 35% (95% confidence interval, 28%-42%), with 9% of patients achieving complete responses and 26% showing partial responses. The median time to progression was 29 weeks for all evaluable patients and 67, 40, and 28 weeks for complete and partial responders and patients with stable disease, respectively. The median duration of survival was 58 weeks. Myelosuppression was the dose-limiting toxicity, resulting in leukopenia (World Health Organization grades 3 and 4) in 73% of the evaluable patients. Other side effects were rare and usually well manageable.
