Abstract

To investigate hepatitis B virus (HBV) reactivation and survival in patients with multiple myeloma (MM) receiving bortezomib-containing regimens, we analyzed 139 patients with MM receiving bortezomib-containing regimens in our hospital. Twenty-seven/139 patients were hepatitis B surface antigen positive (HBsAg+) with nine having DNA levels > 500 IU/mL, including four > 1000 IU/mL. All but five HBsAg+ patients were treated with lamivudine or entecavir before chemotherapy until at least 6 months after chemotherapy or autologous stem cell transplant (ASCT). HBV reactivation occurred in six HBsAg+ patients and two HBsAg− patients, including six who received ASCT. Overall survival and progression-free survival of HBsAg− patients were significantly longer than for HBsAg+ patients (both p < 0.01). From these results, we confirmed that the incidence of HBV reactivation was notable in patients with MM receiving bortezomib-containing regimens, especially those who underwent ASCT. HBsAg+ patients with MM had a poorer prognosis than HBsAg− patients. Prophylactic treatment should be prescribed to all patients with HBsAg+ MM for a minimum duration of 12 months.
