    Hepatitis B virus (HBV) is closely linked to liver cancer. This study found Hepatitis B surface antigen in non-cancerous liver tissue, suggesting HBV can cause cancer even before cirrhosis develops.

    Area of Science:

    • Hepatology
    • Oncology
    • Virology

    Background:

    • Post-hepatitic cirrhosis is the most common precursor to hepatocellular carcinoma.
    • Hepatitis B virus (HBV) infection is strongly associated with hepatocellular carcinoma (HCC).
    • HCC can develop not only in cirrhosis but also in less advanced liver fibrosis.

    Purpose of the Study:

    • To investigate the presence of Hepatitis B surface antigen (HBs Ag) in liver tissue of patients with hepatocellular carcinoma and liver fibrosis.
    • To explore the role of HBV in the development of HCC beyond established cirrhosis.

    Main Methods:

    • Detection of HBs Ag in non-cancerous liver tissue samples from patients diagnosed with liver fibrosis and HCC.
    • Histopathological examination of liver tissue.

    Main Results:

    • HBs Ag was detected in the non-cancerous liver tissue of 40% of cases studied.
    • This indicates that chronic viral hepatitis contributes to liver fibrosis.
    • Hepatocellular carcinoma can arise from chronic persistent hepatitis, not solely post-hepatitic cirrhosis.

    Conclusions:

    • Hepatitis B virus is carcinogenic and can initiate hepatocellular carcinoma development even in early stages of liver disease.
    • Chronic persistent hepatitis, associated with HBV, is a potential precursor for hepatocellular carcinoma.
    • These findings underscore the importance of HBV screening and management to prevent liver cancer.
