Abstract

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 ˜3 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 ™2,000 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 ™2,000 IU/mL and basal core promoter T1762/A1764 mutation were

two independent viral factors for HCC.
