OBJECTIVES: The objective of this study was to determine the association of 19 mutations with frequencies ≥ 10 %
in the core promoter region of hepatitis B virus (HBV) with chronic hepatitis B (CHB), liver cirrhosis,
and hepatocellular carcinoma (HCC).
METHODS: Eight hundred forty-six asymptomatic hepatitis B surface antigen carriers (ASCs), 235 CHB patients,
188 cirrhosis patients, and 190 HCC patients with intact data of HBV genotyping, DNA sequencing,
and serological parameters were studied. Nucleotides with the highest frequencies in HBV genotypes
B and C from all ASCs were treated as wild-type nucleotides.
RESULTS: Mutations at nt.1674, nt.1719, nt.1762, nt.1764, nt.1846, nt.1896, and nt.1913 in genotype
C were signifi cantly associated with CHB, cirrhosis, and HCC, as compared with ASCs. C1673T,
A1726C, A1727T, C1730G, C1766T, T1768A, C1773T, and C1799G in genotype C were signifi -
cantly associated with cirrhosis compared with the CHB patients, whereas these mutations were
inversely associated with HCC compared with the cirrhosis patients. Multivariate regression analyses
showed that age, male, abnormal alanine aminotransferase (ALT), T1768A, A1762T / G1764A, and
A1846T were independently associated with cirrhosis compared with ASCs and the patients with
CHB. Age, abnormal ALT, HBV DNA ( ≥ 10 4 copies / ml), genotype C, C1653T, T1674C / G, T1753V, and
A1762T / G1764A were independently associated with HCC compared with those without HCC. Haplotypic
carriages with two or more HBV mutations were signifi cantly associated with HCC. T1674C / G,
C1653T, and T1753V were specifi c for HCC. A1762T / G1764A had a moderate sensitivity and
specifi city for HCC.
CONCLUSIONS: C1673T, A1726C, A1727T, C1730G, C1766T, T1768A, C1773T, and C1799G in genotype C are
specifi c for cirrhosis. A1846T and T1674C / G are novel factors independently associated with cirrhosis
and HCC, respectively.
