Prognostic Value of C-met Expression in Cholangiocarcinoma

Abstract

Aim: To explore the relationship of clinicopathological features and the proteins of C-met expression in the prognosis of cholangiocarcinoma. Methods: Clinical data and the completed follow-up information of patients with cholangiocarcinoma who underwent cholangiocarcinoma operation from January 2004 to December 2010 were analyzed retrospectively. The relationship of clinicopathological features and C-met in the prognosis of the patients was analyzed. Results: Patients with high expression of C-met had significantly shorter overall survival than those with low expression of C-met, the difference being statistically significant ( P = .003). Patients with high C-met expression had significantly shorter disease-free survival time than those with low expression of C-met, the difference being statistically significant ( P = .009). By COX multivariate analysis, high C-met expression in tumor tissues was an independent risk factor in predicting overall survival and disease-free survival for patients with cholangiocarcinoma ( P = .038, .048, relative risk = 1.390, 1.427). Conclusion: Patients with high C-met expression in cancer tissues had shorter disease-free survival and overall survival. High expression of C-met is an independent risk factor for overall survival and disease-free survival.
