ABSTRACT
Objective@#To investigate the expression and prognostic value of alpha smooth muscle actin(α-SMA) and Ki-67 in retroperitoneal leiomyosarcoma.@*Methods@#Fifty retroperitoneal leiomyosarcoma patients who underwent operation in Chinese People′s Liberation Army General Hospital from May 2002 to December 2015 were retrospectively analyzed. There were 14 males and 36 females form 21 to 79 and an average age of 48. Kaplan-Meier estimations and Cox regression analyses were performed.@*Results@#Of the 50 cases, 45 patients underwent complete resection, and others are not. The overall 1, 3, 5-year survival rates were 86.0%, 46.0% and 28.0%, respectively. Tumor size, extent of resection, pathological stage, and expression levels of Ki-67 and alpha smooth muscle actin (α-SMA) were closely related to the survival of retroperitoneal leiomyosarcoma patients (all P<0.05), respectively. Multivariate analysis showed that pathological grade and degree of surgical resection were independent risk factors in the prognosis of patients (P<0.05).@*Conclusion@#The high expression of α-SMA and Ki-67 are indicators of poor prognosis in retroperitoneal leiomyosarcoma, which can be used as a potential survival predictor in patients with retroperitoneal leiomyosarcoma.
