title: Malignant mixed Mullerian tumours of the uterus--a ten-year experience.
abstract: OBJECTIVE
  To review the clinico-pathological features of malignant mixed Mullerian tumours of the uterine corpus, their prognosis and treatment outcome.
  
  
  METHODS
  A retrospective study of malignant mixed Mullerian tumours of the uterus seen at KK Women's & Children's Hospital from January 1989 to December 1998.
  
  
  CONCLUSIONS
  Twenty-six patients with mean age of 56.5 years were analysed. Twenty (76.9%) were menopausal. None had previous pelvic irradiation. Vaginal bleeding and uterine enlargement were the commonest presenting symptom and sign. Diagnostic dilatation and curettage obtained the diagnosis in 15 patients. Majority of patients had surgery with adjuvant chemotherapy, while adjuvant radiotherapy was offered only recently. Positive peritoneal washings were significantly associated with advanced disease. There were seven patients with stage I, four with stage II, nine with stage III and four with stage IV disease. There were 17 homologous and nine heterologous tumours. Presence of heterologous stromal components did not influence the stage of the disease. Increasing depth of myometrial invasion was associated with poorer survival. Prognosis of patients with stage III and IV disease were poor, with none surviving to two years. All the patients with stage I disease were still alive at the end of the study period. In conclusion, malignant mixed Mullerian tumours of the uterine corpus are aggressive tumours associated with poor prognosis.
