Hepatitis B virus infection in patients with aggressive B-cell non-Hodgkin lymphoma, indolent B-cell non-Hodgkin lymphoma and multiple myeloma / 白血病·淋巴瘤

ABSTRACT

Objective To analyze the infection rate of hepatitis B virus (HBV) in aggressive B-cell non-Hodgkin lymphoma (B-NHL), indolent B-NHL and multiple myeloma (MM) and its relationship with clinicopathological features. Methods The clinical data of 293 aggressive B-NHL, 181 indolent B-NHL and 261 MM patients in Tianjin Medical University Cancer Institute and Hospital from January 2009 to April 2017 were retrospectively analyzed. The difference of HBV infection was compared among three groups. Serum samples from all patients were tested for HBV markers, including hepatitis B surface antigen (HBsAg), hepatitis B surface antibody (HBsAb), hepatitis B e antigen (HBeAg), hepatitis B e antibody (HBeAb) and hepatitis B core antibody (HBcAb) by using chemiluminescence immunoassay. Results The positive rate of HBsAg was 9.2% (27/293), 5.5% (10/181) and 3.8% (10/261), respectively in the aggressive B-NHL group, indolent B-NHL group and MM group. The positive rate of HBsAg in the aggressive B-NHL group was higher than that in the indolent B-NHL group and MM group (χ2＝6.987, P＝0.030), and there was no statistical difference of HBsAg positive rate between the indolent B-NHL group and MM group (P ＞ 0.05). The positive rate of HBsAg, HBeAg, HBcAb in the aggressive B-NHL group was higher than that in the indolent B-NHL group and MM group [4.1% (12/293), 0, 0.8% (2/261); χ2＝ 14.976, P＝ 0.001], and there was no significant difference in the positive rate of HBsAg, HBeAg and HBcAb between the indolent B-NHL group and MM group (P ＞ 0.05). Compared with HBsAg negative aggressive B-NHL patients, HBsAg positive aggressive B-NHL patients showed, higher ratio of stage Ⅲ-Ⅳ [70.4% (19/27) vs. 49.2% (131/266), χ 2 ＝ 4.377, P＝0.036], more frequent involvement of spleen [51.9% (14/27) vs. 23.7% (63/266), χ 2＝ 10.039, P＝ 0.002], more frequent of B symptom [55.6% (15/27) vs. 32.0% (85/266), χ 2 ＝ 6.073, P＝ 0.014], more frequent of elevated total bilirubin [29.6% (8/27) vs. 14.3% (38/266), χ 2 ＝ 4.360, P ＝ 0.037] and more frequent of reduced albumin [55.6% (15/27) vs. 35.7% (95/266), χ 2＝ 4.115, P＝ 0.042]. Conclusions The infection rate of HBV in aggressive B-NHL patients is higher than that in the indolent B-NHL and MM patients. HBsAg positive aggressive B-NHL patients are associated with adverse clinical characteristics.
