TPS、NSE和CEA联合检测对肺癌的诊断价值

目的探讨组织多肽特异性抗原(TPS)、神经元特异性烯醇化酶(NSE)和癌胚抗原(CEA)三项标志物联合检测对肺癌的诊断价值。方法应用酶联免疫吸附试验检测72例肺癌患者和114例健康对照者的TPS、NSE和CEA三项标志物。结果肺癌组三项指标均显著高于健康对照组(P<0.001)。TPS对肺癌诊断的敏感性为84.7%,特异性为89.4%;NSE敏感性为54.1%,特异性为91.2%;CEA敏感性为45.8%,特异性为91.4%;三项标志物联合敏感性为100%。结论TPS、NSE和CEA对肺癌的诊断有一定的价值,三者联合检测有明显的互补性,可显著提高肺癌诊断的敏感性。

Diagnostic value of combined detection of TPS, NSE and CEA in lung cancer

Objective To study the diagnostic value of combined detection of 3 tumor markers, namely tissue polypeptide specific antigen (TPS), neuro-specific enolase (NSE) and carcinoembryonic antigen (CEA), in patients with lung cancer. Methods The serum levels of TPS, NSE and CEA were determined by enzyme-linked immumosorbent assay in 72 patients with lung cancer and 114 healthy adults. Results The levels of the 3 tumor markers in the patient group were significantly higher than those of the healthy control group (P<0.001). The sensitivity of TPS for lung cancer detection was 84.7% with specificity of 89.4%, which were 54.1% and 91.2% respectively for NSE, and 45.8% and 91.4% respectively for CEA. The combined detection of the 3 tumor markers for lung cancer diagnosis had a sensitivity of 100%. Conclusions TPS, NSE and CEA employed separately are helpful in the diagnosis of lung cancer, and their combined detection may significantly improve the sensitivity for lung cancer detection, due to the obvious complementarity of the 3 markers.
