[HBS Ag-positive hepatocellular cancer (pathomorphologic study)].

K Bardadin, M Kobushevska-Farina

    Arkhiv Patologii
    |January 1, 1979
    PubMed
    Summary

    Hepatitis B surface antigen (HBsAg) was found in both cirrhotic and hepatocellular carcinoma tissues. Its presence was significantly higher in cirrhotic tissue than in tumor cells, indicating a link between HBsAg and liver cancer development.

    Area of Science:

    • Hepatopathology
    • Oncology
    • Virology

    Context:

    • Primary hepatocellular carcinoma (HCC) is a major global health concern.
    • Hepatitis B virus (HBV) infection is a leading cause of HCC.
    • Understanding the role of HBsAg in HCC pathogenesis is crucial.

    Purpose:

    • To investigate the presence and distribution of Hepatitis B surface antigen (HBsAg) in hepatocellular carcinoma and surrounding cirrhotic liver tissue.
    • To correlate HBsAg expression with tumor differentiation and cirrhosis morphology.

    Summary:

    • Pathomorphological and histochemical analysis of 7 autopsy cases of primary HCC was conducted.
    • Direct immunofluorescence and Shikata's orsein staining detected HBsAg in hepatocytes and tumor cells.
    • HBsAg was abundant in cirrhotic nodes but scarce in tumor tissue, primarily in well-differentiated areas. All HCC cases exhibited well-differentiated tumors associated with active large nodular cirrhosis.

    Impact:

    • This study highlights the differential expression of HBsAg in HCC development.
    • Findings suggest HBsAg plays a role in the progression from cirrhosis to HCC.
    • Further research into HBsAg's role in specific tumor microenvironments is warranted.
