Abstract

The incidence of hepatocellular carcinoma among patients who have seroconverted to anti-hepatitis B surface antigen (anti-HBs) remains controversial. We report four patients with chronic hepatitis B virus (HBV) infection who had cleared HBsAg and had developed anti-HBs at a later time, but who developed hepatocellular carcinoma (HCC) eventually. The common clinicopathological characteristics of the four patients were: An established diagnosis of precirrhosis or liver cirrhosis more than a decade previously, a long-standing normalization or stabilization at a low level of ALT values due to undetectable HBV DNA by the Amplicore Monitor assay, and a marked reduction of the fibrosis level in the non-tumorous liver obtained at HCC surgery or autopsy compared to the previous histology more than a decade previously. There was no fibrosis in the needle biopsy specimen from one patient. Our findings suggest that HCC due to HBV can occur in the serologically-cured stage if progression to pre-cirrhosis or cirrhosis already has occurred, where the fibrosis level has improved considerably because of the long-term absence of active HBV viremia and inflammation. Active medical intervention to prevent liver cirrhosis for chronic hepatitis B ma...Continue Reading
