title: Radiation-induced hepatitis B virus reactivation in hepatocellular carcinoma: A case report.
abstract: Hepatitis B virus (HBV) reactivation associated with radiotherapy is rare. The present study reports the case of a 46-year-old man that experienced fatal HBV reactivation. The patient suffered from hepatocellular carcinoma (HCC) with portal vein tumor thrombus, which was treated by radiotherapy at a daily fraction of 2 Gy over 5 weeks, up to a total radiation dose of ~50 Gy. The patient presented with fatigue, yellow sclera and abdominal distension ~8 weeks subsequent to the administration of radiotherapy. The liver function tests, including the level of total bilirubin and prothrombin time, suggested acute-on-chronic liver failure. The serum HBV-DNA level had also increased between undetectable levels and 7.2×104copies/ml. Although the present patient with HCC was treated with 0.5 mg/day entecavir for 8 weeks, in addition to radiotherapy, radiation-induced HBV reactivation occurred. The condition of the patient worsened gradually. The present study emphasizes the importance of liver function and HBV-DNA screening and pre-emptive antiviral prophylaxis prior to radiotherapy in patients with HCC.
