CYFRA21-1、NSE、CEA和CA125联合检测对肺癌诊断的价值分析

目的探讨细胞角蛋白-19片段抗原(CYFRA21-1)、神经元特异性烯醇化酶(NSE)、癌胚抗原(CEA)和糖类癌抗原125(CA125)联合检测对肺癌患者的诊断价值。方法从2012年1月至2014年1月该院相关科室共选取研究对象200例,其中肺癌患者100例、肺良性病变患者53例、健康体检者47例。采用电化学发光方法或酶联免疫吸附测定(ELISA)检测患者血清CYFRA21-1、NSE、CEA、CA125的水平,评价不同检测项目组合在肺癌诊断中的灵敏度、特异度和准确度。结果 CYFRA21-1在单项指标检测中对肺癌的诊断的灵敏度和准确度最高,而CA125特异度最高(95.0%)。联合检测的准确度和灵敏度均高于单项检测。4项联合检测的灵敏度为92.0%,特异度为72.0%,准确度为87.0%。结论在肺癌的临床诊断中,多项血清肿瘤标志物联合检测的灵敏度和准确度明显高于单项检测,值得临床推广。

Analysis on the value of combined detection of CYFRA21-1,NSE,CEA,CA125 in lung carcinoma

Objective To investigate the value of combined detection by using tumor markers cytokeratin‐19 fragment antigen (CYFRA21‐l) ,neuron‐specific enolase (NSE) ,carcinoembryonic antigen (CEA) and carbohydrate cancer antigen 125(CA125) in lung cancer diagnosis .Methods 200 people who treated in the hospital in related departments from January 2012 to January 2014 were enrolled in the study .100 of them suffered from lung cancer ,53 suffered from benign lung disease ,the rest 47 were healthy people .Electrochemiluminescence method or enzyme‐linked immunosorbent assay(ELISA) were used to detect serum tumor mark‐ers CYFRA21‐1 ,NSE ,CEA ,CA125 and the sensitivity ,specificity and accuracy of different combinations of test items were evalua‐ted .Results In the single detection of those tumor markers for the diagnosis of lung cancer ,CYFRA21‐1 detection got the highest sensitivity and accuracy ,while CA125 got the highest specificity(95 .0% ) .The sensitivity and specificity of combined detection were both significantly higher than single detections .The sensitivity ,pecificity and accuracy of the combined detection of the 4 tumor markers were 92 .0% ,72 .0% ,and 87 .0% respectively .Conclusion In the clinical diagnosis of lung cancer ,the combined detection of several serum tumor markers get higher sensitivity and accuracy than single detection ,which is worthy of clinical promotion .
