Summary

Hepatitis C antibody is common in patients with hepatocellular carcinoma (HCC) who are negative for hepatitis B. This suggests hepatitis C may be a frequent cause of HCC, though some cases remain unexplained.

Area of Science:

  • Hepatology
  • Viral Hepatitis
  • Oncology

Background:

  • Hepatocellular carcinoma (HCC) is a significant global health concern.
  • A notable proportion of HCC patients in the US are serologically negative for hepatitis B virus (HBV).
  • The role of hepatitis C virus (HCV) in HBV-negative HCC requires further investigation.

Purpose of the Study:

  • To determine the prevalence of hepatitis C antibody in HBV-negative HCC patients.
  • To explore potential causative agents for HCC in the absence of HBV infection.
  • To assess the association between hepatitis C and underlying liver conditions in HCC patients.

Main Methods:

  • Retrospective analysis of 59 HBsAg-negative HCC patients without other known liver diseases.
  • Serological testing for hepatitis C antibody and hepatitis B core antibody.

  • Comparison with control groups: HBsAg-positive HCC patients, cryptogenic cirrhosis patients, and blood donors.

    • Main Results:

    • Hepatitis C antibody was detected in 34% of HBV-negative HCC patients (HCV Ab+/HBc Ab-).
    • All patients positive for HCV antibody had underlying cirrhosis.
    • Hepatitis C antibody prevalence was 14% in HBsAg-positive HCC, 44% in cryptogenic cirrhosis, and 0.5% in blood donors.

    Conclusions:

    • Hepatitis C antibody is prevalent in HBV-negative HCC patients, indicating HCV as a potential common cause.
    • A subset of HCC patients, negative for both HCV and HBV markers, lack an identifiable cause.
    • Advanced serological tests may identify HCV in currently undetected cases.
