A clinical-pathologic study of mixed mullerian tumors of the uterus over a 16-year period—The Medical College of Georgia experience

From 1972 through 1987, 40 patients at the Medical College of Georgia were assessed with a diagnosis of mixed mullerian tumors which constituted 3.5% of all female genital tract malignancies. The mean patient age was 65.3 years; 60% of the patients had stage I disease. Of those patients with clinical stage I disease, more advanced disease was found at celiotomy in 33%. Retroperitoneal nodes were positive for malignancy in 35% of 20 patients who underwent node sampling. Cell washings were positive in 12%, and 9% had omental metastases. Forty-seven percent had homologous tumors; 53% of tumors were heterologous. Relatively poor prognosis was associated with large tumor volume, vascular invasion, nodal metastases, and disease outside the uterus. The overall survival rate was 32%; 14 of 24 patients with stage I disease are dead of disease. Of patients dead of disease, 92.5% had distant metastases. Adjuvant therapy with a combination of VP-16, cisplatin, and irradiation was beneficial in four high-risk patients.
