摘要 目的探讨错配修复基因hMSH2、hMLH1在非霍奇金淋巴瘤中的表达及意义。方法运用免疫组化SP法检测22例B细胞性非霍奇金淋巴瘤及18例NK/T细胞性非霍奇金淋巴瘤中hMSH2、hMLH1蛋白表达情况,并探讨其与非霍奇金淋巴瘤临床病理间的关系。结果NK/T细胞非霍奇金淋巴瘤hMSH2、hMLH1蛋白表达缺失率分别为55.56%、44.44%;B细胞非霍奇金淋巴瘤分别为31.82%、50.00%,两种肿瘤间缺失率比较均无统计学意义。hMSH2、hMLH1蛋白表达缺失与患者性别及肿瘤是否发生于淋巴结无关。结论错配修复基因hMSH2、hMLH1在非霍奇金淋巴瘤肿瘤组织中存在蛋白表达缺失,可导致基因组不稳定,该肿瘤易感。
