Influence of viral load and genotype in the progression of Hepatitis B-associated liver cirrhosis to hepatocellular carcinoma.
Liver Int 2005; 25(2):220-5LI

Abstract

AIM/BACKGROUND

Hepatitis B virus (HBV) is an important factor in the development of hepatocellular carcinoma (HCC). We studied the influence of HBV viral load on HCC occurrence in HBV related liver cirrhosis (LC).

PATIENTS AND METHODS

Ninety-one LC patients were followed up over a period of 7 years. Twenty three patients received Interferon (IFN) therapy.

RESULTS

In 7 years, 23 patients developed HCC. Of them twenty-two (95.6%) were of genotype C. HBV DNA was found to be the only significant variable associated with HCC occurrence on both univariate (P = 0.029) and multivariate analysis (odds ratio 2.33; P < 0.033). The cumulative survival at 5 years was 83% and the annual rate of hepatitis B surface antigen clearance was 0.9 %. All of 17 HCC patients observed over a period of 5 years or more belonged to the continuously high HBV DNA group (annual average >3.7 log copies/ml) and all but one belonged to the continuously high alanine aminotransferase group (annual average >40 IU/l).

CONCLUSION

Patients with genotype C and a continuously high HBV DNA for 5 years or more are at a high-risk group for HCC development. Maintaining continuously low HBV DNA for 3 years or more with anti-viral therapy, may be useful in preventing or delaying HCC occurrence.
