title: [Diagnostic of uterine sarcoma, review of 11 cases].
abstract: BACKGROUND
  Uterine sarcomas are rare but extremely aggressive malignant uterine pathology; mostly incidentally diagnosed at an advanced stage, with a higher aggressiveness and poor prognosis.
  
  
  OBJECTIVE
  To determine the epidemiological profile of women with this diagnosis in Ginecopediatria Hospital, UMAE 48 of IMSS and its correlation with the literature.
  
  
  METHODS
  A retrospective and observational study was done from 2007 to 2014 in UMAE 48, IMSS León, Guanajuato, in which the clinical records of patients with such diagnoses were reviewed.
  
  
  RESULTS
  A total of 11 cases with age range 21-66 years had abnormal bleeding (82%), abdominal pain (64%), enlarged uterus (64%) and isolated elevation of lactic dehydrogenase (55%). The leiomyosarcoma accounted for 55%, sarcoma mixed Mullerian (SMM) 27% and endometrial stromal sarcoma (SEE) in 22% of cases. The stage I was the most frequent (55%) and histological type, which presented a more advanced stage was the SMM (stage IIIC). The hysterectomy with pelvic and paraaortic lymphadenectomy was the most common treatment (67%). The 45% of patients had tumor activity subsequent to treatment and the use of radiotherapy and chemotherapy was not associated with activity.
  
  
  CONCLUSIONS
  Clinical features, risk factors and distribution of the presentation of the various sarcomas were according with previous studies, requiring further research to improve prognosis and survival in this type of tumor.
