Expression analysis of survivin and XIAP in gallbladder cancer: A case-control study in indo-gangetic plain

Abstract

Purpose Gallbladder cancer is a highly mortal disease with poor prognosis because of late presentation of disease. Survivin and X-linked inhibitor of apoptosis (XIAP) are one of the two important members of inhibitors of apoptosis. Thus, this study aimed to look at the expression of Survivin and XIAP in gallbladder cancer patients. Methods Survivin and XIAP expression were investigated in tissues of gallbladder cancer patients (40 cases) and compared with cholelithiasis as control (40 cases) by using immunohistochemistry. Their expression was correlated with clinicopathological parameters. Results Significantly higher (p < 0.05), Survivin protein was expressed in gallbladder cancer (n = 67.5%) than control (n = 35%). But it did not show any significant association with any of the clinicopathological parameter while XIAP was not expressed in the GBC patients (p > 0.05). Conclusion Overexpression of Survivin in gallbladder cancer suggests its possible role and association with poor prognosis. But XIAP has not been found to be associated with gallbladder carcinogenesis. © Springer Science+Business Media, LLC 2017.
