肺癌临床诊断中肿瘤标志物检验分析

Analysis of Tumor Markers in Clinical Diagnosis of Lung Cancer

目的：探究肺癌临床诊断中肿瘤标志物的应用效果。方法选取我院2014年3月～2015年4月期间收治的50例肺癌患者，将其设为观察组，选取同期体检的50例健康人群，将其设为对照组。对比两组受检人员肿瘤标志物检验结果。结果两组受检人员经检查后，其观察组的胞角蛋白19片断21-1、CA125、癌胚抗原以及神经元特异性水平高于对照组，P＜0.05，具有统计学意义。结论肿瘤标记物是诊断肺癌患者的主要参考依据，具有较高的敏感性以及特异性，同时准确率较高，能提升诊断的可靠性。

Objective To explore the effect of tumor markers in clinical diagnosis of lung cancer.Methods Fifty patients with lung cancer who were treated in our hospital from March 2014 to April 2015 were selected as the observation group,and 50 healthy people were selected as the control group. The test results of tumor markers in the two groups were compared.Results Two groups by inspectors after examination,and the observation group of cel keratin 19 fragment 21-1,CA125,cancer embryo antigen and neuron specific level was significantly higher than that of the control group,P〈 0.05, with statistical significance.Conclusion Tumor markers are the main reference for the diagnosis of lung cancer patients,with high sensitivity and specificity,and higher accuracy,can improve the reliability of diagnosis.
