摘要 目的探讨M2-PK在消化系统肿瘤实验室诊断上的应用价值。方法收集正常对照、良性消化系统疾病及消化系统肿瘤患者病例,用酶联免疫法测血浆M2-PK水平,用电化学发光法测CEA、CA19-9、CA72-4水平,并对它们进行比较。结果M2-PK在胃癌、胰腺癌、结直肠癌患者血浆中明显升高,较正常对照组及良性消化系统疾病组有显著差异(P<0.01);M2-PK在胃癌和结直肠癌中阳性率最高(分别为52.4%、78.6%),且较另外3个标志物的阳性率有显著性差异(P<0.01),特异性则比之较低(79.2%);M2-PK分别与CEA、CA19-9、CA72-4联检能提高诊断的敏感性和特异性。结论M2-PK对消化系统肿瘤具有一定的诊断价值,且与其它标志物联检可提高诊断的敏感性和特异性。
