Chemotherapy of adult soft tissue sarcoma with combination of doxorubicin and methotrexate.

Abstract

Thirty-six adult patients with measurable advanced soft tissue sarcoma were treated with a combination of doxorubicin (70 mg/m2) and methotrexate (50 mg/m2) iv every 21 days. Partial remission was seen in ten of 33 evaluable patients (30%). Median duration of remission was 23 weeks, and median survival was 42 weeks. Bone marrow toxicity was the main toxic effect; 23% of the patients had a nadir leukocyte count less than 2.0 X 10(9)/L during therapy. These results do not suggest any therapeutic advantage in adding methotrexate to doxorubicin in this context.
