Implication
Epidemiologic review reveals shifting hepatocellular carcinoma risk in hepatitis B and C infections, highlighting the interplay of viral transmission, host genetics, and environmental factors.
Key Points
- To review the epidemiologic risk factors, transmission patterns, and disease burden associated with hepatocellular carcinoma among populations chronically infected with hepatitis B or hepatitis C virus.
- Synthesized evidence from published epidemiologic studies and meta-analyses examining chronic hepatitis B virus (HBV) and hepatitis C virus (HCV) infections.
- Evaluated global and United States demographic trends, including variations by age, sex, race, host genetics, and environmental cofactors.
- The vast majority of hepatocellular carcinoma cases arise secondary to cirrhosis induced by chronic HBV or HCV infection.
- Demographic and geographic disparities in cancer incidence align with community-level viral prevalence, historical infection timing, and age during initial viral exposure.
- Malignant progression in infected individuals is governed by complex interactions among viral characteristics, host genetic susceptibility, and environmental risks.
