摘  要:目的评价肿瘤标志癌胚抗原(CEA)、神经元特异性烯醇化酶(NSE)、鳞状上皮细胞癌抗原(SCC-Ag)、细胞角蛋白19片断(CYFRA21-1)和p16基因甲基化在肺癌辅助诊断中的价值。方法应用ELISA试剂盒分别测定肺癌患者、非良性疾病患者及健康者血清中的CEA、NSE、SCC.Ag及CYFRA21—1水平,采用甲基化特异性PCR检测血浆中p16甲基化情况;同时运用Fisher判别法探讨该5种肿瘤标志在肺癌辅助诊断中的意义。结果应用Fisher线性判别分析对全部样本判别的灵敏度分别为61.9%(26/42),特异度为92.0%(80/87),准确度为76.7%(99/129),阳性预测值为78.8%(26/33),阴性预测值为75.5%(80/106)。结论该5种肿瘤标志在肺癌辅助诊断方面有一定的参考价值。Objective To investigate the value of detection of five tumor markers ( CEA, NSE, SCC-Ag, CYFRA21-1 and p16 methylation) on the aided diagnosis of lung cancer. Methods The ser- um levels of CEA, NSE, SCC-Ag and CYFRA21-1 were detected in lung cancer patients, malignant dis- ease patients, and healthy people by the kits, p16 was detected by methylation specific PCR. The dis- criminant model was established by Fisher method. Results The sensitivity of the Fisher model for all samples was 61.9% (26/42), the specificity was 92. 0% (80/87), the accuracy was 76. 7% (99/129), the positive predictive value was 78.8 % (26/33), the negative predictive value was 75.5 % (80/106). Conclusions Combined detection of the five tumor markers can provide useful information for the diag- nosis of lung cancer.
