Ifosfamide with and without adriamycin in advanced uterine leiomyosarcoma.

Uterine leiomyosarcomas are rare tumours and the results of treatment of advanced disease are poor. Ifosfamide and Adriamycin are both known to be active drugs in soft-tissue sarcomas. We present our experience using ifosfamide alone and in combination with Adriamycin in advanced or recurrent uterine leiomyosarcomas. Ifosfamide alone was given as a 24-h infusion at doses ranging from 5 to 7.5 g/m2, with mesna rescue. In the combination regimen, ifosfamide was given at a dose of 5 g/m2 and Adriamycin, at a dose of 40 or 60 mg/m2. Ten patients were treated with ifosfamide alone, with only one partial response lasting 6 months. In all, 11 patients were treated with ifosfamide and Adriamycin, which resulted in 1 complete response that lasted 11 months. Although many of the patients had extensive disease and some had undergone prior treatment with other chemotherapy, ifosfamide would appear to have only modest activity at the dose and schedule used.
