MethodsOne hundred and fiftyone cases of HCC tissues and 89 cases of healthy liver tissues were chosen to compare the expression of NRP1 by immunohistochemistry. Then the relationships between different clinical factors and the expression of NRP1 were analyzed by univariate and multivariate statistical analysis. Moreover, the survival rates were compared by survival analysis between different expressions of NRP1 in HCC patients. ResultsEleven cases were lost to followup or died for non HCC disease, and the effective cases in the final study were 140 cases. The positive expression rates of NRP1 in HCC and normal liver tissues were 65.00% and 35.96% respectively, and the difference was statistically significant (χ2=18.843, P<0.001). According to the expression level of NRP1, 140 patients with HCC were divided into negative expression group (n=49) and positive expression group (n=91). Univariate analysis showed that the expression of NRP1 in HCC was correlated with tumor number (χ2=8.025, P=0.005), TNM stage (χ2=26.467, P<0.001), differentiation degree (χ2=15.296, P<0.001), portal vein invasion (χ2=9.054, P=0.003) and hepatic vein invasion (χ2=5.928, P=0.015). Multivariate statistical analysis showed that TNM stage (OR=1.392, 95%CI: 1.1211.730, χ2=8.950, P=0.003), differentiation degree (OR=1.469, 95%CI: 1.1021.958, χ2=6.862, P=0.009), portal vein invasion (OR=1.829, 95%CI: 1.1572.893, χ2=6.665, P=0.010) and hepatic vein invasion (OR=2.161, 95%CI: 1.1723.987, χ2=6.084, P=0.014) were important factors for NRP1 expression. The median survival time of NRP1 negative HCC patients was significantly longer than that of positive group (44 months vs. 23 months), and the difference was statistically significant (χ2=21.922, P<0.001). ConclusionNRP1 is overexpression in HCC tissue and related to the malignant progress of HCC, and this suggests poor prognosis in patients with HCC.
