Summary
Hepatocellular carcinoma (HCC) is a major global cancer. Hepatitis B and C virus infections are key causes, with HBV vaccination showing promise for prevention.
Area of Science:
- Hepatology
- Oncology
- Infectious Diseases
Background:
- Hepatocellular carcinoma (HCC) is a leading cause of cancer death globally, responsible for over 1 million deaths annually.
- Chronic infections with hepatitis B virus (HBV) and hepatitis C virus (HCV) are primary drivers of HCC development.
- The burden of HCC is significant worldwide, necessitating effective prevention strategies.
Purpose of the Study:
- To review the epidemiology and causative links between viral hepatitis and HCC.
- To discuss current and future prevention strategies for HCC, focusing on vaccination and infection control.
Main Methods:
- Literature review of epidemiological data and etiological studies on HCC.
- Analysis of the impact of HBV and HCV on HCC incidence and mortality.
- Evaluation of the efficacy of HBV vaccination and the need for HCV prevention.
Main Results:
- A definitive causal link exists between chronic HBV infection and HCC.
- HCV infection may contribute to HCC risk similarly to or greater than HBV in certain regions.
- HBV vaccination offers excellent prospects for HCC prevention.
Conclusions:
- Preventing HBV infection through vaccination is a highly effective strategy against HCC.
- Reducing transfusion-associated HCV transmission is crucial for preventing HCV-related HCC in the absence of a vaccine.
- Continued efforts in viral hepatitis prevention are essential to reduce the global burden of HCC.
