“Potential explanations supported by these data include increasing early detection of hepatocellular carcinoma, application of curative or locoregional therapies, and, because hepatitis B is the principal cause of hepatocellular carcinoma worldwide and among Asian Americans, effectiveness of vaccination programs and the efficacy of antiviral therapy for hepatitis B in preventing the development of hepatocellular carcinoma.”
However, they noted, “it is unclear how these trends are, or will be, affected by direct-acting antivirals for hepatitis C virus ... eradication of hepatitis C virus will prevent the development of cirrhosis and its complications, potentially changing these trends in the next 5-10 years. However, therapy for hepatitis C viral infection cannot modify the statistically significant trends observed related to alcohol or the expected increase in the burden of nonalcoholic fatty liver disease.”
