Hepatitis C virus genotypes and the development of hepatocellular carcinoma

OBJECTIVE: The aim of this study was to investigate the prevalence of hepatitis C virus (HCV) infection in patients with hepatocellular carcinoma (HCC) in our geographic area, and to determine if there is a correlation between HCV genotypes and the development of HCC. METHODS: Thirty-six patients with HCV-related HCC and 35 controls with HCV-associated cirrhosis without HCC were studied. The diagnosis of HCV infection was performed by the enzyme-linked immunosorbent assay test for the detection of anti-HCV antibodies and by reverse transcription-polymerase chain reaction for the detection of HCV-RNA. HCV genotyping was performed by line probe assay-Inno-LIPA HCV II. The diagnosis of underlying disease in the patients with HCC was performed on the basis of clinical, biochemical or histological evidence. RESULTS: Genotype 1b was found in 28 (77.77%) patients with HCC, and in 16 (45.71 %) controls. There was significant difference in the prevalence of genotype 1b between the patients with H CC and those with cirrhosis without HCC (P < 0.05). Having analyzed the diagnosis of underlying diseases, underlying cirrhosis in 29 (80.55%) and chronic active hepatitis in 7 (19.44%) patients with HCC was found. CONCLUSION: Results of the present study suggest that there is a correlation between HCV genotype 1b and the development of HCC. Our findings also add support to the hypothesis that cirrhosis is a major step in liver carcinogenesis associated with HCV, which suggests an indirect role of HCV in the pathogenesis of HCC.
