Detection of different clonal EBV strains in Hodgkin lymphoma and nasopharyngeal carcinoma tissues from the same patient

Abstract

The ubiquitous herpesvirus Epstein-Barr virus (EBV) is linked to the development of several malignancies, including nasopharyngeal carcinoma (UCNT) and Hodgkin lymphoma (HL). Despite the well-known oncogenic properties of the EBV latent membrane protein 1 (LMP-1), the different oncogenic pathways involved in the pathogenesis of each disease remain unclear. This study reported, for the first time, the case of a patient with sequential development of UCNT and HL. Polymerase chain reaction was used to determine the LMP-1 gene sequence and demonstrate that the two tumours contained different clonal viral genomes, suggesting a central and specific role of EBV infection. © 2008 The Authors.
