Abstract

Hepatocellular carcinoma (HCC) is the most common primary neoplasia of the liver. Major risk factors for hepatocellular carcinoma include chronic liver diseases, carcinogenic agents, and genetic alterations as well as vascular endothelial growth factor (VEGF) involved in angiogenesis process. The aim of this study was to evaluate the association ofVEGF-A(C936T and A1154G) with HCC and cirrhosis, in addition to serum levels of VEGF, clinical profile, lifestyle habits, and comorbidities. A total of 346 individuals were studied: 102 with HCC (G1), 117 with cirrhosis (G2), and 127 controls (G3). Polymorphisms were analysed by PCR/RFLP and serum levels of VEGF by ELISA. Alpha error was set at 5%. The wild-type genotype of both polymorphisms prevailed (P>0.05). In G1, 23% of the patients died, with no relation to genetic profile (P>0.05). Increased VEGF level was observed in G1 and G3, related to the mutant allele ofVEGF-C936T andVEGF-A1154G, respectively, and compared with the wild-type genotype (P=0.0285;P=0.0284, resp.) as well as G1 versus G2 and G3 forVEGF-C936T and G1 versus G2 forVEGF-A1154G (P<0.05for both). In conclusion, there is a relationship between mutant alleles ofVEGF-C936T andVEGF-A1154G polymorphisms and higher VEGF level, making them potential markers for HCC.
