Abstract:

?目的:检测基质金属蛋白酶抑制剂2(tissueinhibitorofmetalloproteinases2,timp2)在肺癌患者血浆中的蛋白水平及其临床意义。方法:通过对214例血浆样本,包括114例肺癌患者、100例健康人,采用酶联免疫吸附试验(enzymelinkedimmunosorbentassay,elisa)进行检测,测定timp2蛋白的血浆浓度,检验其诊断肺癌的敏感性和特异性。结果:elisa检测结果显示,肺癌患者血浆中timp2蛋白浓度为(74.56±16.70)ng/ml,显著低于正常对照人群(170.98±48.61)ng/ml(p<0.01)。且timp2蛋白在晚期(ⅲ+ⅳ期)肺癌患者血浆中的水平(81.57±15.62)ng/ml显著高于早期(ⅰ+ⅱ期)肺癌患者(69.16±15.63)ng/ml(p<0.01);在肿瘤直径小于或等于3cm肺癌患者血浆中timp2蛋白水平显著低于肿瘤直径大于3cm的肺癌患者(p<0.01),并且与肺癌的远处转移相关(p<0.01)。当cutoff值定为103.29ng/ml时,timp2检测肺癌的敏感性为97.4%,特异性为82.8%。结论:检测血浆中timp2的蛋白水平有助于肺癌的诊断。
