Abstract

An association between Epstein-Barr Virus (EBV) infection and lymphoproliferative diseases has been reported with EBV + diffuse large B cell-lymphoma (DLBCL) of the elderly described as a distinct entity. In a cohort of 218 human immunodeficiency virus (HIV)-negative patients with diffuse large B-cell lymphomas, we detected EBV-DNA in 25% of whole blood (WB) samples at diagnosis. Presence and viral load in WB, mononuclear cells or plasma did not predict the presence of EBV in the tumor biopsy. Positive Hepatitis C virus (HCV) serology was associated with a higher frequency of EBV in WB. Patients with EBV-DNA in WB had a significantly shorter progression-free (p = 0.02) and overall survival (p = 0.05) after immunochemotherapy with R-CHOP (Rituximab, Cyclophosphamide, Doxorubicin, Vincristine, Prednisolone). We conclude that detection of EBV in WB is not a surrogate marker for EBV-association in diffuse large B-cell lymphoma, however it associates with worse outcome.
