Changes in the Epidemiology of Hepatocellular Carcinoma in Asia.

Hepatocellular carcinoma (HCC) is one of the most common cancers worldwide, with high morbidity and mortality, and the incidence is on the rise. HCC imposes a heavy healthcare burden on Asian countries due to the presence of multiple HCC risk factors in this area. Chronic hepatitis B virus (HBV) infection, chronic hepatitis C virus (HCV) infection, non-alcoholic liver disease (NAFLD), aflatoxin and alcohol intake are the causes of HCC that cannot be ignored. Compared with the pre-vaccination era, universal vaccination of newborns reduces the incidence of HCC. Anti-viral therapy with nucleos(t)ide analogues also causes a decline in HCC incidence. Early screening and direct-acting antiviral agent are beneficial to the prevention and treatment of HCV. For HCC caused by NAFLD and other reasons, lifestyle changes are imperative. This paper introduces the epidemiological trends of HCC in Asia and highlight future efforts. Focusing on prevention may be the most effective way to improve the prognosis of this hard-to-treat cancer.
