The biology of hepatocellular carcinoma (HCC) is unique compared with other gastrointestinal tract cancers because most cases are caused by viral agents. It would follow that modulation of factors related to the infection has the potential to alter the natural history of HCC tumorigenesis. Indeed, the use of antiviral therapy in patients with chronic hepatitis B virus (HBV) infection in endemic populations of Asia has been shown to significantly reduce the risk of HCC.1 Despite this well-documented benefit, very little is known about the efficacy of antiviral therapy after a potentially curative resection of HBV-associated HCC. A recent meta-analysis2 identified only 2 studies on this subject and reported a favorable effect on survival, but not recurrence, with adjuvant therapy including antiviral treatments.
