Abstract:
Objective To investigate the effects of vascular endothelial growth factor receptor-1(VEGFR-1) in the invasion and metastasis of hepatocellular carcinoma(HCC)by detecting the expression of VEGFR-1 in HCC tissues.Methods Paraffin-embedded tissue which containing HCC tissues and adjacent tissues were prepared from patients(n=82)with HCC,then were analyzed by immunohistochemical technique for the expression of VEGFR-1,epithelial marker E-cadherin and mesenchymal marker Vimentin.The relationship between the expression of VEGFR-1 and pathological parameters,and the correlation between VEGFR-1 and E-cadherin,VEGFR-1 and Vimentin were analyzed.Results The expression rates of VEGFR-1 in HCC tissues and adjacent tissues were 89%(73/82)and 0,respectively.The difference of VEGFR-1 expression in portal vein tumor thrombus,tumor capsule,stage,size and differentiation grade of tumor had statistical significance(x2=22.192,15.934,16.751,20.154,6.487,P＜0.05).The expression of VEGFR-1 had effect on the 1-,2-year recurrence rate and 2-year survival rate (x2=0.983,0.958,0.847,P＜0.05),but not on 1-year survival rate(x2=0.359,P＞0.05).The expression of VEGFR-1 was negatively correlated with that of E-cadherin(r=0.765,P＜0.01)but positively with that of Vimentin (r=1.469,P＞0.05).Conclusions VEGFR-1 may play an important role in invasion and metastasis of HCC.Epithelial-mesenehymal transition that induced by VEGFR-1 may contribute to the invasion and metastasis of HCC.
