摘要 目的:比较原位杂交技术(Insuithybridization,ISH)和免疫组织化学方法(Immunohischemical,IHC)检测B细胞性淋巴瘤(B-celllymphoma)和反应性增生病变(Reactivehyperplasia,RH)中免疫球蛋白轻链限制性的灵敏度和精确度。方法:收集112例淋巴结病变[B-celllymphom(an=62)和RH(n=50)],用ISH和IHC法检测免疫球蛋白轻链κ、λ的限制性。结果:ISH法,62例B细胞性淋巴瘤轻链有限制性45例(72.58%),50例淋巴结反应性增生病变没有限制性表达。IHC法,62例淋巴瘤有轻链限制性29例(46.77%),50例反应性增生病例6例有限制性表达(12%)。统计检验两种方法检测的结果显示表达有显著性差异(χ2=8.9338,P<0.05)两种方法差异有显著性。结论:在诊断与鉴别诊断B细胞性淋巴瘤和反应性增生病变中,用ISH法检测轻链κ、λmRNA的基因序列,比用IHC法检测免疫球蛋白轻链蛋白κ、λ限制性更灵敏和精确。
