Title: Expression of VEGF, HIF-1 alpha and EGF in hepatocellular carcinoma
Abstract: Objective To investigate the expressions of vascular endothelial growth factor (VEGF) , hypoxia inducible factor 1 alpha (HIF 1α) and epidermal growth factor (EGF) in hepatocellular carcinoma (HCC) and their clinical significance. Methods The expressions of VEGF, HIF 1α and EGF in 36 cases of HCC and corresponding paraneoplastic tissues and normal liver tissues (6 cases) were studied by immunohistochemistry assay. ResultsThe expression rate of VEGF, HIF 1α and EGF in HCC tissue was 89%, 67% and 75% respectively, higher than those in paraneoplastic tissues and normal liver tissues ( P 0 05). The expression of VEGF and HIF 1α in HCC with microscopic venous invasion were significantly higher than those in HCC without microscopic venous invasion ( P 0 05). The 1, 2 year survival rates were 100% in VEGF negative HCC group, 87% and 22% in VEGF slight positive group, 54% and 0 in VEGF strong positive group. The differences of the survival rates among the three groups were significant ( P 0 05). The 1, 2 year survival rates were 100% and 60% in EGF negative HCC group,70% in EGF slight positive group and 27% and 0 in EGF strong positive group ( P 0 05). Conclusions There are overexpression of VEGF, HIF 1α and EGF in HCC. The expressions of VEGF, HIF 1α and EGF in HCC are closely correlated with the malignant behaviors and poor prognosis of HCC.
