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.
Conclusion: 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.
