Association between the Epstein-Barr virus and Hodgkin's lymphoma in the North-Eastern part of Hungary: effects on therapy and survival.
This retrospective study included 109 patients with Hodgkin's lymphoma (HL; 45 females, 64 males). In 47 of the 109 HL patients (43%), immunohistochemical analysis of their formalin-fixed, paraffin-embedded histologic samples revealed Epstein-Barr virus (EBV) by latent membrane protein (LMP) 1. The highest virus association (50%) was found with the mixed cellularity histologic subtype, especially in patients aged 11-20 and >50 years. Virus positivity in nodular sclerosis was 35% (negative cases accumulated in patients aged 15-30 years). Regarding clinical stages, histologic subtypes, general symptoms, treatments employed and response to treatment, the EBV-positive group was not significantly different from the virus-negative group. During the mean follow-up time of 83 months (9-300 months), the overall or event-free survival of EBV-negative patients was more favorable than that of EBV-positive patients, although the difference was not significant (p = 0.16 and p = 0.24, respectively). EBV infection may be involved in the pathogenesis of HL in our Hungarian study cohort, but it does not significantly affect clinical symptoms, therapeutic results or complete and event-free survival of HL patients.
