Four patients with metastatic ovarian mixed Müllerian sarcoma (2 homologous, 2 
heterologous) were treated with mesna, doxorubicin, ifosfamide, and dacarbazine 
(MAID) chemotherapy. Two of four patients had optimal debulking. Three of four 
patients responded to chemotherapy, with two complete responses of 34- and 
46-month duration. The MAID regimen appears to be active in patients with 
ovarian sarcoma.
