Abstract:
Recently, hepatitis B virus (HBV) genotypes and mutations have been reported to be related to hepatocellular carcinoma (HCC). This cross‐sectional case–control study examined the relationship between HCC and mutations in the enhancer II/core promoter and precore regions of HBV by comparing 135 Korean HCC patients infected with HBV genotype C2 (HBV/C2; HCC group) with 135 age‐, sex‐, and hepatitis B e antigen (HBeAg) status‐matched patients without HCC (non‐ HCC group). Age and sex were also matched between HBeAg‐positive and ‐negative patients. The prevalence of T1653, A1689, V1753, T1762/A1764, T1846, A1850, C1858, and A1896 mutations was evaluated in this population. The prevalence of the T1653 mutation in the box α region, the A1689 mutation in between the box α and β regions, and the T1762/A1764 mutations in the basal core promoter region was significantly higher in the HCC group compared to the non‐HCC group (8.9% vs. 2.2%, P = 0.017; 19.3% vs. 4.4%, P 〈 0.001; and 60.7% vs. 22.2%; P 〈 0.001). Among HBeAg‐negative patients, the frequency of the T1653 mutation was higher in the HCC group. Regardless of HBeAg status, the prevalence of the A1689, and T1762/A1764 mutations was higher in the HCC group than in the non‐HCC group. However, no association was observed between mutations in the precore region and HCC. Upon multivariate analysis, the presence of the T1653, A1689, and T1762/A1764 mutations was an independent predictive factor for HCC. The addition of the T1653 or A1689 mutation to T1762/A1764 increased the risk of HCC. In conclusion, the T1653, A1689, and/or T1762/A1764 mutations were associated with the development of HCC in Korean patients infected with HBV/C2. J. Med.
