Detection of Epstein-Barr Virus in Nasal T-cell Lymphoma

The close relationship between Epstein-Barr virus (EBV) and nasal T-cell lymphoma (NTL) has frequently been reported. However, the status of the infection, either lytic or latent, is obscure. This study involved 16 patients with NTL. Phenotypes of lymphoma cells were examined by immunohistochemical...

Description
Summary:The close relationship between Epstein-Barr virus (EBV) and nasal T-cell lymphoma (NTL) has frequently been reported. However, the status of the infection, either lytic or latent, is obscure. This study involved 16 patients with NTL. Phenotypes of lymphoma cells were examined by immunohistochemical staining using CD3, CD4, CD8, CD20 and CD45RO monoclonal antibodies. EBV-encoded small nuclear RNA (EBER)-1 and EBV Not I tandem repeat region were detected by reverse transcription, using a rapid ( &#104 60 min) in situ hybridization technique. Tumor cells expressed at least one T-cell marker, such as CD3, CD4, CD8 and CD45RO. CD20 was not detected in any of the cases. EBER-1 was identified in all cases; no Not I tandem DNA repeat was demonstrated. All cases demonstrated a T-cell phenotype. These data suggest that NTL is associated with EBV infection in the latent phase.
