Clinical features of advanced ovarian mixed mesodermal tumors and treatment with doxorubicin- and cis-platinum-based chemotherapy

Records of 15 patients with stage III and IV malignant mixed mesodermal tumors of the ovary treated between 1977 and 1988 were reviewed. All patients had primary surgery; 13 were given postoperative chemotherapy including doxorubicin and cis-platinum. Median survival for patients receiving chemotherapy is 16 months; 62% were alive at 12 months and 31% at 24 months. Progression-free responses were seen in 85% of treated patients and 55% of these recurred. All recurrences involved the pelvis and were predominantly mesenchymal. Serum CA-125 values accurately reflected tumor presence in 82% of tested patients. Cytoreductive surgery followed by treatment including doxorubicin- and cis-platinum-based chemotherapy is effective in treatment of disseminated ovarian mixed mesodermal tumors, but additional components must be added to achieve durable responses and consistently prolonged survivals.
