Abstract

The role of survivin in gallbladder cancer (GBC) has not been evaluated. We investigated survivin protein expression in serum of patients with gallbladder diseases (cholelithiasis, n = 30; GBC, n = 39) and compared with healthy controls (n = 25). Clinicopathological parameters, diagnosis and prognosis of patients with GBC were correlated with the expression of serum survivin by enzyme-linked immunosorbent assay. Significantly higher (P < 0.0001) expression of survivin protein was observed in GBC as compared to cholelithiasis and control. Increased survivin expression was significantly associated with higher tumor stage (stage III vs. stage II; P < 0.0001) and cellular differentiation (poor and moderate vs. well differentiated; P < 0.0001) in GBC. No significant correlation was observed with any of the other clinico-pathological parameters studied. The cutoff value of survivin protein of 79 pg/ml with sensitivity of 81.16 % and specificity of 80 % differentiated the diseased group (cholelithiasis or GBC) from control group were as the cutoff value of 109 pg/ml differentiated GBC from cholelithiasis with a sensitivity of 82.05 % and specificity of 93.33 %. Though not significant, increased expression of survivin was associated with median overall survival (12 vs. 18 months; P = 0.05) in GBC patients. Our study suggests that survivin protein in serum could be both a useful diagnostic marker and an important prognostic factor for GBC.
