ABSTRACT
Objective@#To investigate the clinicopathological features of EBV-positive T/NK cell lymphoproliferative diseases (EBV+ T/NK-LPD).@*Methods@#The clinical characteristics of 156 cases of EBV+ T/NK-LPD were collected from August 2002 to March 2015 at Beijing Friendship Hospital, Capital Medical University. Immunohistochemical staining, EBER in situ hybridization and clonal analysis of TCR gene were performed. All patients were followed up.@*Results@#There were 106 male and 50 female patients; patients′ age ranged from 1 to 75 years (median 20 years). The course of the diseases before diagnosis ranged from 2 to 540 months (median 20 months). Fever was noted in 122 patients (78.2%), 108 patients had lymphadenopathy (69.2%), and 75 patients had hepatosplenomegaly (48.1%). Thirty-three cases were grade 1, 68 cases were grade 2, and 55 cases were grade 3. TCR gene arrangement analysis was performed in 45 cases, and 33 cases (73.3%) showed clonal rearrangement. The follow-up period ranged from 1-134 months, and 44 patients (28.2%) died. There was a trend of increased death rate associated with increasing grade (P>0.05).@*Conclusions@#There are many types of EBV+ T/NK-LPD, and they can be classified as systemic, relatively localized and localized. The prognosis should be based on a comprehensive analysis of pathology and clinical data. There is no significant correlation between morphological grade and mortality. An important goal of therapy is to prevent serious complications.
