摘要 目的探讨糖类抗原(CA)19-9联合癌胚抗原(CEA)检测老年胃癌的诊断价值。方法老年胃癌患者72例作为病例组,同时随机选取非胃癌患者72例作为对照组,应用电化学发光免疫分析法分析两组CA19-9及CEA水平,分别计算CA19-9、CEA单独及联合诊断胃癌的敏感性、特异性及准确性。结果胃癌组CA19-9及CEA的平均水平分别为(92.35±36.71)U/L、(17.15±7.14)μg/L,显著高于对照组〔(36.65±18.26)U/L及(3.58±2.64)μg/L〕(P<0.05)。随着胃癌临床分期的加重、肿瘤分化级别的减低,CA19-9、CEA的水平进行性升高(P<0.05)。CA19-9单独检测胃癌的灵敏度、特异度分别为45.8%、93.1%,而CEA单独检测的灵敏度、特异度分别为50.0%、90.3%,二者联合检测时为84.7%、86.1%,准确性为85.4%。结论血清CEA、CA199联合检测有助于提高胃癌诊断的敏感性及准确性,对胃癌的早期诊断有重要价值。
