Abstract

This phase II study was designed to verify the activity and safety of an intensive epirubicin/ifosfamide schedule in untreated soft tissue sarcoma (STS) patients by using both the agents at the identified maximal tolerated doses. 39 adult patients were treated with epirubicin at 55 mg/m2, on days 1 and 2 (total dose per cycle 110 mg/m2) combined with ifosfamide at 2.5 g/m2 days 1-4 (total dose per cycle 10 g/m2), with equidose mesna uroprotection and G-CSF support. Treatment was given on an ambulatory basis, at 3-week intervals. The overall objective response (OR) rate was 59% (95% confidence interval, CI, 43-72%), with 5 complete responses (13%) and 18 partial responses (46%); 12 partial responders were rendered disease-free following surgery. The median survival time was 19 months, being 23 and 13 months, respectively, for responding and non-responding patients. The median time to response was 40 days (range 21-60). Treatment-related toxicity was overall acceptable. The OR of 59% was the highest ever reported in our consecutive studies in advanced STS, confirming that improved therapeutic efficacy can be obtained with intensified regimens in such a disease; both the response duration and survival were also longer. The observed activity proved to be interesting with regard to the high response rate in the lung (86%), as well as the proportion of patients rendered disease-free by early surgery after the achievement of a partial response (55%). Both these findings may be important in the multimodality approach to patients with lesions potentially resectable for cure.
