血清CA19-9、CA125、CEA、CYFRA21-1、CA15-3和Galectin-3在胰腺病变鉴别诊断中的作用

目的探讨血清CA19-9、CA125、CEA、CYFRA21-1、CA15-3和Galectin-3的单项检测和联合检测在胰腺病变鉴别诊断中的作用。方法用雅培ARCHITECT i2000化学发光免疫分析仪分别检测125例胰腺导管腺癌患者和115例胰腺炎患者血清中的CA19-9、CA125、CEA、CYFRA21-1、CA15-3和Galectin-3水平。结果经受试者工作特征曲线(receiver operating characteristic curve,ROC)分析,CA19-9的曲线下面积(area under the curve,AUC)最大,为0.856,灵敏度和特异性分别75.2%和92.2%,其次为CA125(AUC=0.706),CEA(AUC=0.689)和CYFRA21-1(AUC=0.672)。而CA15-3(AUC=0.568)和Galectin-3(AUC=0.537)很难鉴别胰腺癌和胰腺炎。CA19-9、CA125和CEA联合检测的AUC为0.910,灵敏度和特异性分别为77.6%和93.9%,均高于CA19-9单项指标。CA125和CYFRA21-1在胰腺癌晚期组的血清水平明显高于早期组(P<0.05),而其他四项指标没有显著差异(P>0.05)。结论血清CA19-9在胰腺病变鉴别诊断中具有重要的价值,而Galectin-3的价值不高,血清CA19-9、CA125和CEA的联合检测可提高CA19-9单项对胰腺癌的诊断效能。CA125和CYFRA21-1和胰腺癌的肿瘤分期相关。
