Abstract
Objective To investigate the EB virus (EBV) infection and its clinical significance in angioimmunoblastic T-cell lymphoma(AITCL).Methods 62 patients diagnosed as AITCL between 2008 Jan and 2011 Dec were retrospective analyzed.All cases were re-confirmed and classified with the histology and immunology according to 2008 WHO Classification.In situ hybridization of EBV encoded RNA (EBV-EBER) was performed.Clinical characteristics and follow-up data of patients were collected.Results 42 ％ (26/62) AITCL cases were EBER-positive.EBV infection was found to be significant correlation with age over 60 years and poor response to therapy (P =0.025,P =0.049,respectively).However,EBV infection had no relationship with the overall survival,the presence of B symptom and the Ann Arbor stage.Conclusion In AITCL,EBV infection seems not to be associated with the overall survival,B symptom and Ann Arbor stage,but it may have impacts on theraputic response. Key words: Lymphoma, T-cell, angioimmunoblastic; EB virus; EBER; Prognosis
