摘    要:目的探讨EB病毒(EBV)在不同类型淋巴瘤中的表达差异及对用于检测EBV表达的3种实验方法(免疫组织化学、原位杂交、PCR)进行比较分析。方法收集明确诊断淋巴瘤石蜡组织57例,包括结外NK/T细胞淋巴瘤(NK/TCL)鼻型12例、血管免疫母细胞性T细胞淋巴瘤(AITCL)13例、霍奇金淋巴瘤(HL)12例、弥漫大B细胞淋巴瘤(DLBCL)20例,应用免疫组织化学(IHC)、原位杂交(ISH)、聚合酶链反应技术(PCR)分别检测淋巴瘤中EBV蛋白(LMP-1)、EBV潜伏相关RNA(EBERl)、EBV(DNA)的表达情况。结果57例淋巴瘤组织中EBV蛋白(LMP-1)、EBER1、EBVDNA总阳性表达率分别为17.5%(10/57)、47.4%(27/57)、50.9%(29/57)。其中NK/TCL鼻型为8.3%(1/12)、83.3%(10/12)、91.7%(11/12);AITCL为30.8(4/13)、53.8%(7/13)、61.5%(8/13);HL为33.3%(4/12)、41.7%(5/12)、41.7%(5/12);DLBCL为5.00%(1/20)、25.0%(5/20)、25.O%(5/20)。PCR及原位杂交检测方法比免疫组化更敏感(P〈0.05)。结论EBV感染在不同类型的淋巴瘤中表达存在差异,3种检测方法之间的阳性表达率也不同且ISI-I和PCR检测方法优于IHC。

Abstract:Objective To investigate the expression of EBV in different types of lymphomas and comparative three different detection methods(IHC,ISH,PCR). Methods We collected 57 lymphomas including extranodal NK/T cell nasal type lymphoma 12 cases,angioi- miunoblastic T cell lymphoma 13 cases, Hodgkin's lymphoma 12 cases and diffuse large B - cell lymphoma 20 cases. The expression of EBV protein LMP - 1, EBER1 mRNA and EBV DNA in 57 lymphomas were analyzed by immunohistoehemistry (IHC) ,in situ hybridiza- tion(ISH) and Polymerase chain reaction(PCR). Results The positive results of EBV LMP- 1 protein expression,EBER1 mRNA ex- pression and EBV DNA expression were 17.5% (10/57) ,47.4% (27/57) ,50.9% (29/57) respectively in 57 cases of lymphoma, inclu- ding 8.3% ( 1/12 ) , 83.3% ( 10/12 ) , 91.7% ( 11/12 ) in extranodal NK/T cell nasal type lymophoma, 30.8 (4/13) , 53.8% ( 7/13 ) , 61.5% (8/13)in AILCL,33.3% (4/12) ,41.7% (5/12) ,41.7% (5/12)in HL,5.00% (1/20) ,25.0% (5/20) ,25.0% (5/20) in DL- BCL. The expression rate of EBV by PCR and ISH was higher than IHC. Conclusion There was a close association between EBV infec- tion and lymphomas,with variation among different types of lymphomas. The expression rate of EBV by IHC, ISH, PCR was variation. The expression rate of EBV by PCR and ISH was higher than IHC.
