Abstract
A 49-year-old-man, a healthy carrier of hepatitis B virus (HBV), received chemotherapy with a rituximab/cyclo- phosphamide/doxorubicin/vincristine/prednisolone (R-CHOP) regimen for non-Hodgkin's lymphoma. At the first course of chemotherapy, not only the liver function but the HBV DNA level was elevated. These symptoms were diagnosed as hepatic injury induced by HBV reactivation, and, therefore, entecavir (ETV) was started. As a result, although the treatment with ETV decreased the HBV DNA level, liver function values were remarkably elevated again (over 3 times the levels before beginning ETV). ETV was discontinued because of suspicion regarding the onset of hepatic injury it caused. After switching to lamivudine (LVD), the liver function quickly improved and no problems were observed with renewal of the R-CHOP regimen. In addition, the HBV DNA level decreased and 3 courses of R-CHOP were performed successfully. In our case, the hepatic injury was induced by ETV, although anti-HBV medicine was used for the treatment of HBV reactivation according to the guideline. Therefore, the medical staff must carefully and consistently observe patients with HBV infection after chemotherapy.
