      PURPOSE: To assess antitumor response and time to progression (TTP) with docetaxel compared with doxorubicin in first-line treatment of advanced and/or metastatic soft tissue sarcoma. PATIENTS AND METHODS: Patients with measurable soft tissue sarcoma lesions and adequate bone marrow, liver, and renal function were entered onto the study. They were randomized to either docetaxel 100 mg/m(2) given as a 1-hour intravenous infusion every 3 weeks or doxorubicin 75 mg/m(2) given as a bolus injection every 3 weeks. A maximum of seven cycles of treatment were scheduled. The study was designed as a randomized phase III study evaluating TTP by log-rank model. There was a clause for premature closure of the trial if fewer than five responses were observed among the first 25 assessable patients in the docetaxel treatment arm. RESULTS: Eighty-six patients were entered onto the study; 85 were assessable for toxicity and 83 for response. The rate of severe granulocytopenia was not significantly different between the two arms. Nausea (P =.001), vomiting (P <.001), and stomatitis (P =.005) were more common with doxorubicin therapy, whereas neurotoxicity was more frequent with docetaxel treatment. The response rate to doxorubicin therapy was 30% (95% confidence interval, 17% to 46%), whereas no responses to docetaxel therapy were seen (P <.001). In view of this, the trial was closed prematurely and the phase III study part was not conducted. CONCLUSION: Docetaxel is inactive in soft tissue sarcomas and cannot be recommended for further use in treatment of this disease.
