Abstract: The prevalences of infections with hepatitis C virus (HCV) and hepatitis B virus (HBV) were determined in 110 Thai patients with liver cancer, of whom 80 and 30 had histological diagnoses of hepatocellular carcinoma (HCC) and cholangiocarcinoma (CCA), respectively. Hepatitis B surface antigen was detected in 63.8% of HCC patients and 16.7% of those with CCA. Antibodies to HCV, detected by a third-generation enzyme immunoassay, were found in 11.3% of HCC patients and in no CCA patient. HCV ribonucleic acid (RNA) was detected by polymerase chain reaction in 6 anti-HCV positive patients, and also in 2 patients who had no detectable anti-HCV antibody. A total of 11 patients had evidence of HCV infection 8 of whom were infected with HCV alone. HCV genotypes were determined in all 8 patients who had HCV RNA; genotype 3a was the most common (62.5%). These results demonstrate that, in Thailand where both HBV and HCV are endemic, HBV infection is still the most important risk factor for HCC, but HCV also has an important role in those without HBV infection. In addition, the genotypic distribution of HCV in HCC in Thailand is similar to that in the general population. No specific association between genotype 1b and HCC was observed.
