Although carcinosarcoma occurs in various locations throughout the body, it 
rarely originates in the ovary. Chemotherapy has been minimally beneficial. This 
case describes a patient with carcinosarcoma of the ovary who responded 
minimally to chemotherapy used for epithelial carcinomas but had a complete 
response after receiving chemotherapy used for sarcomas. The patient relapsed 
within 1 year after receiving cisplatin therapy. She was treated with mesna, 
ifosfamide, Adriamycin, and dacarbazine (MAID) chemotherapy and after one cycle 
of chemotherapy she had no evidence of tumor. She has received six cycles of 
chemotherapy without evidence of progression 13+ months since beginning MAID 
therapy. MAID chemotherapy may be useful in the treatment of carcinosarcoma of 
the ovary.
