abstract

  • The Epstein-Barr virus (EBV) is associated with distinct forms of human lymphoid malignancies, including the endemic (eBL) and sporadic forms of Burkitt's lymphoma (sBL) and acquired immunodeficiency syndrome-associated non-Hodgkin lymphoma (AIDS-NHL). However, whether EBV has a pathogenetic role in these tumors or is a passenger virus has not been conclusively demonstrated. One element to distinguish between these two possibilities is to determine whether EBV infection has preceded and, thus, possibly contributed to clonal expansion, or whether infection has occurred after clonal expansion and thus is unlikely to contribute to pathogenesis. Toward this end we analyzed the structure of the heterogeneous genomic termini of EBV as markers of clonal infection in a panel of eBL (11 cases), sBL (9 cases), and AIDS-NHL (10 cases) biopsies. We show that EBV termini are uniformly clonal in sBL, eBL, and AIDS-NHL, strongly suggesting that EBV infection has preceded and, thus, most likely contributed to clonal expansion in these malignancies.
