Limited %R 10.4254/wjh.v5.i1.43 %X Reactivation of hepatitis B virus (HBV) during chemotherapy is a well known complication in patients with chronic hepatitis B and cancer. The clinical manifestations range from subclinical elevation of liver enzymes to severe, potentially fatal fulminant hepatitis. Reactivation can occur in a patient with previous inactive HBV infection; either an inactive carrier or a patient with resolved hepatitis. Everolimus is a mammalian target of rapamycin (mTOR) inhibitor approved in renal cell carcinoma, neuroendocrine tumours and breast cancer. mTOR inhibitors are a new generation of drugs for targeted treatment; therefore, little about their side effects is known. Here, we report a patient with renal cell carcinoma who experienced a flare of hepatitis B infection during treatment with everolimus. Clinicians should be aware of HBV reactivation in patients who are undergoing treatment with everolimus, and screening for hepatitis B infection and prophylactic antiviral treatment should be considered. %K Hepatitis B %K Virus reactivation %K Everolimus %K Mammalian target of rapamycin inhibitors %K Immunosuppressive treatment %K Renal cell carcinoma %U http://www.wjgnet.com/1948-5182/full/v5/i1/43.htm
