Abstract
Previous epidemiological studies suggest an association between hepatitis B virus (HBV) infection and B-cell non-Hodgkin lymphoma (B-NHL). The aim of our study was to evaluate clinical characteristics and serological indicators of HBV activity in patients who were diagnosed with both HBV infection and indolent or aggressive B-NHL. Seventy-two patients with current or resolved HBV infection and B-NHL were identified between 2000 and 2017 at our institution. Forty-five (63%) and 27 (37%) patients were identified with aggressive and indolent B-NHL, respectively. In indolent B-NHL, the proportion of HBsAg-positive patients was significantly higher compared with aggressive B-NHL (59% vs 38%, P=.03). HBV-DNA levels were significantly higher in patients with indolent compared to aggressive B-NHL (P=.01). In the subgroup analyzes of follicular lymphoma (FL) and diffuse large B-cell lymphoma (DLBCL), the rate of HBsAg positivity in FL is significantly higher than that in DLBCL (83% vs 44%, P=.04), and HBV-DNA levels were significantly higher in FL compared with DLBCL (P=.007). Our results suggest that serological HBV activity is higher in patients with both HBV infection and indolent B-NHL compared to those with aggressive B-NHL.
