Hepatitis B virus core-related antigen is useful for surveillance of
hepatocellular carcinoma recurrence in a patient with occult hepatitis B
virus infection: Case report
A 73-year-old woman with occult hepatitis B virus (HBV) infection was
diagnosed with hepatocellular carcinoma (HCC). Serum HBV core-related
antigen (HBcrAg) was elevated and HBV covalently closed circular DNA
(cccDNA) was presented in the liver tissue. This report shows HBcrAg
might be a predictive factor for development of HCC.
