The role of ifosfamide in the treatment of adult soft tissue sarcomas, Ewing's sarcoma, and osteosarcoma: a review.

Ifosfamide is an analogue of cyclophosphamide that has been extensively investigated in sarcomas. Like doxorubicin and dacarbazine, it belongs to the class of drugs active against advanced soft tissue sarcomas; its optimal use in combination regimens has not been identified. In the treatment of osteosarcoma and Ewing's sarcoma, ifosfamide has been identified as an effective drug. Nonetheless, in these diseases, too, its optimal place in combination therapy has not yet been determined.
