title: [Surgical treatment of esophageal leiomyosarcoma: a review of the literature and report of 11 cases].
abstract: OBJECTIVE
  To discuss the clinical biocharacteristics, diagnosis, operation and prognosis of esophageal leiomyosarcoma (ELS).
  
  
  METHODS
  Clinical materials and follow-up results of 11 surgically treated ELS patients were analyzed.
  
  
  RESULTS
  All 11 cases received radical resection of tumor. The 5-year survival rate was 54.5% (6/11). Grossly, two types of ELS were observed: the polyp form (4 cases) and invasive form (7 cases). The 5-year survival rate was 75.0% and 42.9%, respectively. Two patients died of local recurrence, another 2 cases died of distant metastasis.
  
  
  CONCLUSIONS
  In patients with ELS surgically treated, prognosis of polyp form ELS is better than that of invasive form ELS. Local recurrence and distant metastasis are the major cause of death.
