Answer

Chronic hepatitis B infection is the major contributor to the development of approximately 50% of cases of hepatocellular carcinoma (HCC) worldwide. [34] Studies indicate that the level of hepatitis B virus (HBV) DNA, which indicates viral replication, is a strong predictor for cirrhosis and HCC regardless of other viral factors. [34] Approximately 9% of patients in western Europe who have cirrhosis develop HCC due to hepatitis B infection at a mean follow-up of 73 months. The probability of HCC developing 5 years after the diagnosis of cirrhosis has been established at 6%, and the probability of decompensation is 23%.
