摘要 目的探讨联合测定血清糖蛋白抗原199(CA199)、血清糖蛋白抗原125(CA125)、癌胚抗原(CEA)及胃蛋白酶原(PG)对胃癌早期诊断的临床价值。方法应用化学发光法对142例住院患者血清中CA199、CA125、CEA、PGⅠ、PGⅡ水平进行了检测,观察胃癌组患者各项水平与健康对照组的差异,并用ROC曲线计算各指标的敏感性和特异性。结果胃癌组与健康对照组和其他疾病组比较CA199、CA125、CEA、PGⅠ、PGⅡ、PGⅠ/PGⅡ均有显著差异,萎缩性胃炎组与健康对照组比较仅PGⅠ、PGⅡ、PGⅠ/PGⅡ有显著差异,单项检测中PGⅠ/PGⅡ的敏感性(74.2%)和特异性(88.9%)最高,四项联合检测时敏感性和特异性分别为94.3%和92.3%。结论 CA199、CA125、CEA、PGⅠ/PGⅡ的联合检测对胃癌早期诊断具有较高的临床价值。
