[Divergence Analysis of Hepatitis Virus Infection between Aggressive and Indolent B Cell Non-Hodgkin's Lymphoma].

ABSTRACT

OBJECTIVE: To investigate the prevalence rate of hepatitis B virus(HBV)and hepatitis C virus(HCV)between aggressive and indolent B cell non-Hodgkin's lymphoma (B-NHL), and to compare the different infection rate of Hepatifis Virus between the 2 groups. METHODS: Integrated clinical information of 733 newly diagnosed indolent B-NHL patients and 148 aggressive B-NHL patients from January 1994 to January 2014 was retrospectively analyzed. The difference of hepatitis virus infection was compared between the 2 groups. RESULTS: The positive rate of HCV-Ab was 1.8% in 881 newly diagnosed B-NHL patients. The HCV prevalence was 1.9% and 1.35% in the indolent and aggressive B-NHL group respecitvely. Compared with general population, the HCV positive rate was significantly higher in the whole B-NHL group and the indolent group(1.8% vs 0.4%,1.9% vs 1.4%)(P<0.01), while it was not significantly different in the aggressive group (1.35% vs 0.4%)(P=0.068). The positive rate of HCV-Ab was not significantly different between the indolent and the aggressive group (1.9% vs 1.35%)(P=0.639). The HBs-Ag positive rate in the whole B-NHL group was 9.0%, which was significantly higher than that in the general population (9.0% vs 7.2%)(P<0.05). The positive rate of HBs-Ag in the indolent and aggressive B-NHL group was 7.9% and 14.2%, respectively. It was significantly higher in the aggressive group than that in the indolent one (14.2% vs 7.2%)(P<0.01). Compared with the general population, the aggressive group had significantly higher prevalence rate of HBV. However, it was not significantly different between the indolent group and the general population (7.9% vs 7.2%)(P>0.05).In the aggressive B-NHL group,the co-expression of HBs-Ag,HBe-Ag and anti-HBc-Ab was 4.4%, which was higher than that in the indolent one (4.7% vs 1.2%)(P<0.01). However, compared with the indolent group, the co-expression of HBs-Ag, anti-HBe-Ab and anti-HBc-Ab was not significantly different in the aggressive group (5.5% vs 6.1%)(P>0.05). CONCLUSION: The HCV is more relevant with indolent B-NHL, the HBV has more relevance with the aggressive patients.
