Comparison between using hepatocellular carcinoma (HCC) risk scores and the HCC national guideline to identify high-risk chronic hepatitis B patients for HCC surveillance in Thailand.

The use of HCC risk scores in non-cirrhotic HBV patients reduced the number of patients needing surveillance greatly. HBV cirrhotic patients should have HCC surveillance without the need for risk score calculation. Patients with a family history of HCC should undergo surveillance until proven unnecessary in prospective trials.
