title: Ifosfamide plus doxorubicin in metastatic adult sarcomas: a multi-institutional phase II trial.
abstract: Between April 1986 and March 1987, 42 patients with advanced sarcoma were entered in this multi-institutional trial evaluating ifosfamide plus doxorubicin. The majority of patients had leiomyosarcoma and malignant fibrous histiocytoma although two patients with sarcomas of osseous origin were included. Doxorubicin was administered at a dosage of 60 mg/m2 by continuous push and ifosfamide 5.0 g/m2 by continuous infusion over 24 hours with mesna (7.5 g2 over 36 hours) with courses repeated every 3 weeks until progression, toxicity cumulative doxorubicin dosage of 450 mg/m2. Overall, 15 (36%) patients demonstrated objective remissions including three complete and 12 partial remissions (95% confidence limits, 21.5% to 52.0%). The median duration of remission was 7.0 months and the median survival time for all eligible patients was 8.0 months. Toxicity was predominantly hematologic with the median leukocyte nadir being 1,300 per microliter of blood and documented sepsis in six patients. These data support activity for ifosfamide plus doxorubicin in patients with advanced sarcoma, but the actual contribution of ifosfamide needs to be evaluated through prospective randomized trials which are currently underway.
