Description
Background/Aims The role of viral factors in the pathogenesis of hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) is still inconclusive. Whether virological features such as viral load or mutants might change with the progression of HCC remains unknown. A case–control study including patients with early HCC and HBsAg carriers who are presumed to be at the minimal potential of HCC as controls might better identify factors significantly associated with HCC development. Methods Virological features were compared between 59 patients with early HCC (a solitary tumor of size B3 cm) and 101 patients with non-early HCC. A case–control study was performed by comparing 59 patients with early HCC and 1:2 age-matched inactive carriers with persistent normal alanine aminotransferase (ALT) levels. Results HBV DNA levels, HBV genotypes, and the frequency of precore A1896 and basal core promoter T1762/ A1764 mutations showed no significant difference between patients with early HCC and those with non-early HCC. In the case–control study, patients with early HCC had significantly higher HBV DNA levels, and higher frequencies of genotype C HBV and basal core promoter T1762/A1764 mutation, but a similar frequency of precore A1896 mutation. Multiple logistic regression analysis identified HBV DNA levels C2,000 IU/mL and basal core promoter T1762/A1764 mutation as being independent factors for HCC development. Additionally, there was a synergistic effect between high viral load and basal core promoter T1762/A1764 mutation on HCC development. Conclusions Virological features did not change significantly with the progression of HCC. HBV DNA levels C2,000 IU/mL and basal core promoter T1762/A1764 mutation were two independent viral factors for HCC.
