Hepatitis B surface antigen and primary liver cancer
Summary
Hepatitis B infection, indicated by hepatitis B surface antigen (HBsAg), is significantly more common in patients with primary liver cancer (PLC). This highlights a potential link between HBsAg and liver cancer development.
Area of Science:
- Hepatology
- Oncology
- Virology
Background:
- Hepatitis B virus (HBV) infection is a global health concern.
- The association between HBV and primary liver cancer (PLC) is well-established but requires further investigation in diverse populations.
Purpose of the Study:
- To determine the incidence of hepatitis B surface antigen (HBsAg) in patients with primary liver cancer (PLC).
- To explore the relationship between HBsAg and different types of liver disease associated with PLC.
Main Methods:
- Radioimmunoassay was used to detect HBsAg in the sera of 184 patients (92 with PLC, 92 controls).
- Histological examination of liver disease was performed in 56 PLC patients.
Main Results:
- HBsAg was detected in 31 of 92 PLC patients, significantly higher than in 8 of 92 controls (P < 0.01).
- HBsAg prevalence was higher in patients with post-collapse cirrhosis (66.6%) compared to chronic Budd-Chiari syndrome (22.2%) among PLC patients.
Conclusions:
- Hepatitis B infection is significantly associated with primary liver cancer.
- The role of hepatitis B in PLC pathogenesis may vary geographically and depend on the type of underlying liver disease.
