摘要 目的 评价肿瘤相关抗原(TAA)微阵列检测在胃癌诊断中的应用价值.方法 采用ELISA法检测58例胃癌患者(胃癌组)和60例健康志愿者(对照组)血清中的6种TAA水平,包括癌胚抗原(CEA)、糖蛋白抗原19-9(CA19-9)、糖蛋白抗原12-5(CA12-5)、糖蛋白抗原24-2(CA24-2)、糖蛋白抗原72-4(CA72-4)和血管内皮生长因子(VEGF),对单一和微阵列检测结果进行流行病学筛选试验进行评价,并确定最佳微阵列组合.结果 胃癌组患者6种血清TAA水平高于对照组(P均<0.05);单一TAA检测时,灵敏性在37.93%~ 56.90%,正确指数为0.313~0.436;多种TAA微阵列检测的灵敏性和正确指数高于单一抗体检测,其中6种TAA微阵列检测为最佳组合,灵敏性为89.66%,特异性为81.67%,正确指数为0.713.结论 联合6种TAA微阵列检测对胃癌具有较高的诊断价值,可提高胃癌的检出率,有助于早期诊断.
