Hepatitis C virus (HCV) has emerged as a leading cause of hepatocellular carcinoma (HCC). In most cases, the virus causes HCC in the presence of chronic hepatic inflammation, advanced fibrosis, and cirrhosis. A combination of viral, environmental, and genetic factors are likely to determine the host immune response to the infection as well as the progression to HCC. Clinical and epidemiologic studies have identified many of the risk factors associated with HCC development in patients with chronic hepatitis C. Male sex and older age are considered as independent risk factors for HCC, while alcohol consumption accelerates fibrosis, increasing the risk for progression to HCC. Obesity, diabetes mellitus, nonalcoholic fatty liver disease, aflatoxin exposure and occult hepatitis B infection, all contribute to a higher HCC risk. HCV patients infected with HCV genotype 3 are also more likely to develop HCC and genetic variations such as single nucleotide polymorphisms, which may also alter the risk. Sustained virological response to the antiviral therapy results in significantly more favorable long-term outcomes. The incidence of HCC after HCV eradication is similar between patients treated with peginterferon plus ribavirin and direct-acting antiviral therapy.
