摘要 目的探讨甲状腺转录因子1(TTF-1)、细胞角蛋白7(CK7)和天门冬氨酸蛋白酶A(Napsin A)联合检测对肺腺癌的诊断价值。方法选择非小细胞肺癌患者100例,组织病理学诊断为肺腺癌42例、肺鳞癌58例。采用免疫组化法检测肺腺癌及肺鳞癌组织TTF-1、CK7和Napsin A表达。以病理检查结果为金标准,分析三者单项或联合检测诊断肺腺癌的效能。结果肺腺癌组织与鳞癌组织TTF-1阳性表达率分别为92. 86%(39/42)、1. 72%(1/58),CK7阳性表达率分别为100%(42/42)、36. 21%(21/58),Napsin A阳性表达率分别为85. 71%(36/42)、0。肺腺癌组织TTF-1、CK7、Napsin A阳性表达率均明显高于肺鳞癌组织(χ~2分别为84. 298、42. 529、77. 679,P均<0. 01)。TTF-1单项检测诊断肺腺癌的敏感性和特异性分别为92. 86%、98. 28%,诊断准确率为96. 00%。CK7单项检测诊断肺腺癌的敏感性和特异性分别为100%、63. 79%,诊断准确率为79. 00%。Napsin A单项检测诊断肺腺癌的敏感性和特异性分别为85. 71%、100%,诊断准确率为94. 00%。联合检测时,三项均阳性诊断肺腺癌的敏感性和特异性分别为83. 33%、100%,诊断准确率为93. 00%;三项中至少一项阳性诊断肺腺癌的敏感性和特异性分别为100%、62. 07%,诊断准确率为78. 00%。结论 TTF-1、CK7、Napsin A单项检测均可用于鉴别非小细胞肺癌组织学类型;三者联合检测有助于提高肺腺癌诊断的敏感性或特异性,同时还能使诊断准确率保持在较高水平。
