摘要 目的探讨癌胚抗原(CEA)、血清神经元特异性烯醇化酶(NSE)、细胞角蛋白19片段(CYFRA21—1)在肺癌中的临床诊断价值。方法采用电化学发光免疫分析技术测定85例肺癌患者(肺癌组)、36例肺良性疾病患者(良性病变组)血清中的CEA、CYFRA21—1和NSE水平。结果NSE、CEA、CYFRA21-1在肺腺癌患者血清中的浓度分别为(8.80±1.53)μg/L、(83.30±3.52)μg/L、(5.90±0.58)μg/L,在鳞癌中分别为(8.60±1.47)μg/L、(14.30±3.25)μg/L、(8.30±1.03)μg/L,在小细胞未分化癌中分别为(33.80±4.24)μg/L、(13.60±1.95)μg/L、(34.80±5.64)μg/L均高于良性病变组的(7.80±1.58)μg/L、(7.90±1.12)μg/L、(1.86±1.53)μg/L,差异有统计学意义(均P〈0.01)。CYFRA21-1在鳞癌的敏感度最高(72.2%);NSE在小细胞未分化癌敏感度最高(63.6%);CEA在腺癌中的敏感度最高(69.8%)。3项指标联合检测肺癌的敏感度为72.9%。特异度为91.4%。结论血清CYFRA21—1、CEA和NSE的联合检测有助于临床对肺癌的诊断,并对组织分型有较高的参考价值。 Objective To explore the diagnostic value of 3 tumor markers, Carcinoembryanic antigen(CEA), Cytokeratin fragment 21-1 (CYFRA21-1) and Neuron-specific enolase(NSE), in different histological lung cancers. Methods Concentration ofNSE, CEA andCYFRA21-1 were (8.80±1.63)μg/L, (83. 30 ±3. 62) μg/L, (6.90± 0.68) μg/L in patients with adenocarcinoma; ( 8.60 ±1.47) μg/L, ( 14.30 ±3.25 ) μg/L, (8.30±1.03 )μg/L in patients with squamous cell carcinoma and (33.80 ±4.24) μg/L, ( 13.60 ± 1.95 ) μg/L, (34.80 ±5.64)μg/L in patients with undifferentiated small cell cancer. The concentration of these three tumor markers in lung cancer group were significantly higher than those in benign disease group [ (7.80 ± 1.58) μg/L, (7.90 ± 1. 12) μg/L, ( 1. 86 ± 1.53 ) μg/L, (P 〈 0.01 ) ]. The sensitivity of CYFRA 21-1 in squamous cell carcinoma was 72.2% ; CEA in adeno- carcinoma was 69.8% ; NSE in undifferentiated small cell cancer was 63.6%. The sensitivity and specificity of associated tumor markers were 72. 9% and 91.4%. Conclusion CYFRA21-1, CEA and NSE are useful for diagnosis of lung cancer with different histological type, especially with combined detection of the 3 serum tumor markers.
