Epstein-barr virus-positive diffuse large B-cell lymphoma of the elderly: what we know so far

Jorge J Castillo et al. Oncologist. 2011.

Abstract

Epstein-Barr virus-positive (EBV-positive) diffuse large B-cell lymphoma (DLBCL) of the elderly is a newly described lymphoproliferative disorder recently included as a "provisional" entity in the most current WHO Classification of Tumours of Haematopoietic and Lymphoid Tissues. The objective of this review is to provide a thorough and current summary of the existing knowledge of this subtype of DLBCL. We will review and discuss the incidence of EBV expression in DLBCL, the pathogenesis behind EBV-driven malignant transformation of B cells, the different EBV latency patterns associated with DLBCL, the distinct pathologic characteristics of EBV-positive DLBCL, the potential predictive and prognostic value of EBV tumoral status in patients with DLBCL, and potential strategies for the treatment of this rare entity, which is characterized by a suboptimal response to therapy and poor survival rate.

Pathologic characteristics of EBV-positive DLBCL of the elderly. (A): EBV-positive DLBCL of the elderly infiltrating soft tissue. Hematoxylin and eosin, ×100. (B): Monomorphic pattern displaying large cells with immunoblastic features, characterized by central prominent nucleoli. Hematoxylin and eosin, ×400. (C): Polymorphic pattern displaying large cells admixed with abundant reactive inflammatory cells, mainly small lymphocytes. Hematoxylin and eosin, ×400. (D): CD20. Positivity for CD20 is consistent with a B-cell lineage. Immunohistochemistry, ×400. (E): MUM-1 (nuclear pattern). Most EBV-positive DLBCL of the elderly are positive for MUM-1, consistent with a nongerminal center cell phenotype. Immunohistochemistry, ×400. (F): EBV-encoded RNA (EBER) (nuclear pattern). In situ hybridization, ×400. Abbreviations: DLBCL, diffuse large B-cell lymphoma; EBV, Epstein-Barr virus.
