To review the clinicopathological characteristics and prognosis of patients with malignant mixed Mullerian tumor (MMMT) of the uterus. METHODS: Retrospective clinical study was done on 26 patients diagnosed with the MMMT of the uterus at our hospital from Janurary, 1994 to December, 2004. Demographic data, pathologic findings, stages, treatment, prognosis and survival time were reviewed. RESULTS: The median age of patients was 59 years. Most of the patients (76.9%) were in the postmenopausal state. The most common symptom was vaginal bleeding (65.4%). There were 17 patients (65.4%) with stage I, 3 patients (11.6%) with stage II, 4 patients (15.4%) with stage III, 2 patients (7.6%) with stage IV disease in this study. Of the hysterectomy specimens, 4 (15.4%) of them were heterologous tumors, 22 (84.6%) of them were homologous tumors. Overall 5 year survival rate of all stages was 60% and the patients with advanced stages (III, IV) showed poorer prognosis than the patients with early stages (I, II) (P=0.001). Myometrial invasion depth was also significant prognostic factor (P<0.001). CONCLUSION: The MMMT of the uterus is a highly malignant tumor and the significant prognostic factor is the FIGO stage and myometrial invasion depth.
Key Words: Malignant mixed Mullerian tumor, Prognosis, FIGO stage, Myometrial invasion depth
