Discussion: In contrast, analysis of sera or plasma from Japanese subjects with AC,
CH,
LC and
HCC infected with HBV genotype C showed that the percentage of
T1753V mutation increased with progression of
liver disease [Takahashi et al., 1999].
Result: As expected, the frequencies of
C1653T,
T1753V,
A1762T/
G1764A mutations in these 'free' HBV DNAs from both tumor derived and non-tumor derived samples were at the same level as that for the serum derived samples of the
LC group and
HCC group (Table 2).
Result: Meta-analysis of previously published data, both our own and that of others, has shown that the number of mutations of the HBV genome (
C1653T,
T1753V and
A1762T/
G1764A) gradually increased with disease progression and correlated with hepatocarcinogenesis (Table 2).
Result: The frequencies of
C1653T
