[A pilot study of high-dose zorubicin in advanced stages of soft tissue sarcoma in adults].
High-dose anthracyclines, doxorubicin 75 mg/m2 and epirubicin 150-180 mg/m2, are the most active drugs in the treatment of advanced soft tissue sarcoma. These dosages are associated with significant hematological toxicity for both drugs and a high risk of cardiotoxicity for doxorubicin. The aim of this pilot study was to investigate the activity of zorubicin in advanced soft tissue sarcoma, with a dosage supposed to be equihematotoxic to epirubicin 180 mg/m2. Twenty of 21 patients who had been included in the study were evaluable for response, 15 males and five females, median age 41 (range 20-67) years. All patients received zorubicin 600 mg/m2 per cycle divided in 3 days, the intercycle interval being 4 weeks. The cardiac function was monitored by determinations of left ventricular ejection fraction before each cycle. Therapeutic response was the following: 2/20 patients (10%) complete response, 6/20 (30%) partial response, 6/20 (30%) stable disease and 6/20 (30%) progressive disease, the overall response rate being 8/20 (40%). Complete responses were observed in a patient with undifferentiated sarcoma of the mediastinum and in a patient with unresectable angiosarcoma of subcutaneous tissues. The major toxicity was hematological, with granulocytopenia grade 4 occurring in 42/66 cycles, and the nadir on day 10 of the treatment cycle. Nine of 66 cycles were complicated by febrile neutropenia and stomatitis of any grade was recorded in only 1/66 cycles. No cumulative cardiotoxicity was observed up to a total cumulative zorubicin dose of 3,000 mg/m2.
