Primary central nervous system lymphoma occurs more often in patients with AIDS. Epstein-Barr virus (EBV) has been detected in these tumours, but the degree of association has not been defined because of both the highly restricted expression of EBV in malignant tissue and the lack of a technique that is reliable in formalin-fixed paraffin-embedded specimens. EBV-transformed lymphocytes contain short non-protein coding EBV transcripts (EBERs), which are expressed in much higher quantity than other EBV-latency transcripts. We describe a new strategy for detection of latent EBV with these transcripts as targets for in-situ hybridisation. 18 cases of Al DS-related primary CNS lymphoma from a consecutive necropsy series together with specimens from 3 further cases were studied. In each case, a strong positive signal over tumour cells indicated abundant expression of the EBV-EBER1 transcript. This 100% association suggests that the pathogenesis of these AIDS-associated lymphomas may differ from the systemic disease in which only 30-50% of tumours are associated with EBV. A pathogenetic role for EBV was further supported by showing expression of a viral protein (the latent membrane protein) that is implicated as an effector for EBV-associated lymphomagenesis. EBV might have a role as a tumour marker in the diagnosis and management of AIDS-related primary CNS lymphoma.
