Abstract:
:Advanced age and high hepatitis B virus (HBV) DNA level are risk factors associated with the development of HBV-related hepatocellular carcinoma (HCC). However, little is known about the role of viral load in the carcinogenesis of HCC in young people. A total of 183 HBV-related HCC patients and 202 HBV carriers were therefore enrolled to compare serum viral loads in young (=40 years of age) and old (>40 years of age) age groups. Other factors associated with the development of HCC were also analysed. The results showed that serum alanine aminotransferase (38.7 +/- 24.1 vs 58.4 +/- 65.4 IU/L, P = 0.006) and HBV DNA levels (log(10) titre: 4.20 +/- 1.33 vs 4.80 +/- 1.39, P = 0.053) were lower in young HCC patients than in old HCC patients. There was a positive correlation between age and serum HBV DNA level in HCC patients but a negative correlation in HBV carriers. Young HCC patients with HBV genotype B infection had higher viral loads than those with genotype C infection (log(10) titre: 4.79 +/- 1.34 vs 3.27 +/- 0.60, P = 0.001). By multivariate logistic regression analyses, high serum HBV DNA level was associated with the development of HCC in old patients [odds ratio (OR) 1.584, 95% confidence interval (CI) 1.075-2.333] rather than in young patients (OR 0.848, 95% CI 0.645-1.116). In conclusion, viral factors in association with the development of HBV-related HCC in young patients may be different from their old counterparts. The complicated interplay between host and virus could be responsible for the emergence and aggressive outcome of early-onset HCC.
