Abstract: ObjectiveTo investigate the expressions of Livin and vascular endothelial growth factor (VEGF) in pancreatic carcinoma and their cilinical significances. MethodsThe expressions of Livin and VEGF proteins were tested by immunohistochemistry in 68 cases of pancreatic carcinomas and 44 cases of adjacent paracancerous tissues.ResultsThe positive rates of Livin in pancreatic carcinomas and adjacent paracancerous tissues were 73.5% and 4.5% respectively, and the difference was statistically significant (χ2=48.137, P<0.001). The positive rates of VEGF in pancreatic carcinomas and adjacent paracancerous tissues were 69.1% and 13.6% respectively, and the difference was statistically significant (χ2=29.147, P<0.001). The expressions of Livin and VEGF were related with tumor differentiation (χ2=6.061, P=0.014; χ2=6.592, P=0.010), TNM stage (χ2=4.175, P=0.041; χ2=9.992, P=0.002), lymph node metastasis (χ2=11.731, P=0.001; χ2=12.002, P=0.001) and neural invasion (χ2=9.950, P=0.002; χ2=7.433, P=0.006). Significantly positive correlation was found between the expressions of Livin and VEGF by using Spearman correlation analysis (r=0.320, P=0.008). Survival analysis showed that the expressions of Livin and VEGF were independent prognostic factors in pancreatic carcinoma. ConclusionLivin and VEGF involve in the development, migration and metastasis of pancreatic carcinoma. Livin may upregulate the expression of VEGF, which may lead to the angiogenesis and migration in pancreatic carcinoma.
