Abstract
- Summary. The aim of the study was to investigate the prevalence of mutations of basal core promoter (BCP) and precore (PreC) region of hepatitis B virus (HBV) and their association with hepatocellular carcinoma. A total of 341 untreated older HBV patients were divided into three groups: chronic hepatitis B (CHB, 185), cirrhotic hepatocellular carcinoma (LC-HCC, 113) and non-cirrhotic hepatocellular carcinoma (non-LC-HCC, 43). HBV BCP and PreC mutations and genotypes were determined by direct sequencing. Using univariate analysis, age (≥45 years), single mutations including A1896 and A1899 and multiple mutations T1762/A1764 + A1896, T1762/A1764 + A1899 and T1762/A1764 + A1896 + A1899 were more frequently detected in LC-HCC and non-LC-HCC patients than in CHB patients. BCP T1762/A1764 mutations were highly detected in LC-HCC patients than in CHB patients. Multivariate logistic regression analysis (adjusted for age and gender) revealed that among HBeAg-positive patients, BCP T1762/A1764 mutations (OR, 5.975; P = 0.05), PreC A1899 mutation (OR, 4.180; P = 0.013) and multiple mutations T1762/A1764 + A1899 (OR, 6.408; P = 0.006) were independently associated with the development of LC-HCC; PreC A1899 mutation (OR, 7.347; P = 0.034) was also independently associated with the development of non-LC-HCC. On the other hand, among HBeAg-negative patients, PreC A1896 mutation (OR, 5.176; P = 0.002) and multiple mutations T1762/A1764 + A1896 (OR, 4.149; P = 0.007) were independently associated with the development of non-LC-HCC. These results indicated that older age (≥45 years) was associated with LC-HCC and non-LC-HCC development. BCP T1762/A1764 mutations and PreC A1899 mutation were associated with the LC-HCC development in HBeAg-positive patients. PreC A1896 mutation was associated with the non-LC-HCC development in HBeAg-negative patients. [ABSTRACT FROM AUTHOR]
