Reactivated hepatitis B is a potentially serious disorder that can result in liver failure and death. It has been described with a wide variety of immunosuppressive interventions, such as cancer chemotherapy, anti-rejection drugs and the use of tumour necrosis factor-α inhibitors and monoclonal antibody to B-cell antigen. It now appears reasonable to consider transarterial chemoembolization (TAC) for hepatocellular carcinoma as an additional medical intervention associated with hepatitis B reactivation. Pre-emptive antiviral treatment of hepatitis B surface antigen (HBsAg) carriers can prevent serious complications arising from immunosuppressive-induced viral reactivation. Specific recommendations for antiviral prophylaxis in HBsAg carriers undergoing TAC should be added to international management guidelines.
