[Detection of Epstein-Barr virus in T cell lymphoma and clinicopathologic analysis]

Abstract

Background: To study the relationship of Epstein-Barr virus (EBV) and T cell lymphoma.

Methods: Sixty cases of T cell lymphomas were examined for the presence of EBV using in situ hybridization for EBV encoded RNA (EBERs).

Results: EBERs were detected in tumor cells in 37(69.8%) of 53 cases with peripheral T cell lymphoma, but in none of seven cases of precursor T lymphoblastic lymphoma. The total detected EBERs were 37(61.6%) in 60 cases of T cell lymphomas. By Revised European-American Lymphoma(REAL) classification, EBERs were detected in 2/2 angioimmuno-blastic T cell lymphoma,17/18 angiocentric lymphoma, 4/6 anaplastic large cell lymphoma and 14/27 peripheral T cell lymphoma, unspecified (51.9%). The frequency of EBERs among the extranodal peripheral T cell lymphoma was higher than the nodal (P less than 0.01) there was no significant correlation with the sex, age and clinical stage.

Conclusions: This study indicated that high incidence of EBV was observed in peripheral T cell lymphoma, with predilection for angiocentric lymphoma and extranodal presentation.
