title: [A clinical analysis of 153 uterine sarcomas].
abstract: OBJECTIVE
  To evaluate the prognostic factors and treatment methods of 153 uterine sarcomas.
  
  
  METHODS
  153 cases of the uterine sarcoma were eligible for this retrospective study. Of the 153 cases, 48 were leiomyosarcomas, 47 mixed mesodermal sarcomas, 37 endometrial stromal sarcomas, 8 carcinosarcomas, 4 sarcoma botryoides, 1 fibrosarcoma, and 8 malignant lymphomas. 81 cases were in stage I, 11 stage II, 33 stage III and 11 stage IV. 38 cases were treated by surgery alone, 24 by surgery combined with radiation therapy, 50 by surgery plus chemotherapy, 23 by surgery plus radiation therapy and chemotherapy, 4 by radiation therapy alone, 3 by chemotherapy alone, and 11 by radiation therapy plus chemotherapy.
  
  
  RESULTS
  The overall 5-year survival rate was 49.0%, and that of leiomyosarcomas, mixed mesodermal sarcomas and endometrial stromal sarcomas was 46.9%, 34.1% and 69.3% respectively (P < 0.01). The 5-year survival rate of lesions limited to the uterus (stage I + II), and that of pelvic cavity invasion (stage III) and distant metastases was 59.6%, 25.6% and 10.0% respectively (P < 0.01. When the uterus was smaller than a 3 months pregnant uterus, the 5-year survival rate was 49.9%. When the uterus size larger than a 3 months pregnant uterus, the survival rate was 18.8% (P < 0.05). Premenopausals surviving 5-year accounted for 56.3% and post-menopausal 28.9% (P < 0.01).
  
  
  CONCLUSIONS
  The prognosis of uterine sarcoma is significantly associated with histologic type, clinical and surgico-pathological stage, uterine size and pre- or post-menopausal status. Radiation or chemotherapy alone is palliative. Postsurgical adjuvant radiotherapy significantly decreased vaginal and pelvic recurrences rates. A combination of surgery, radiotherapy and chemotherapy can reduce pelvic recurrence as well as enhance survivals.
