5种血清肿瘤标志物在肺癌辅助诊断中的应用价值

摘要

目的 探讨糖类抗原(CA)153、CA125、神经元特异烯醇化酶(NSE)、癌胚抗原(CEA)、细胞角蛋白片段(CYFRA)21-1在肺癌中的诊断价值.方法 2014年10月至2016年4月来该院进行诊治的60例肺癌患者纳入肺癌组,60例肺良性疾病患者纳入肺良性疾病组,另选择60例健康体检者作为对照组,收集3组受试者空腹静脉血标本,采用免疫化学发光法检测CA153、CA125、NSE、CEA、CYFRA21-1水平,并进行比较.结果 5项肿瘤标志物对于肺癌检测的灵敏度及特异度存在一定的差异,其中NSE和CA153的特异度是5项肿瘤标志物中最高的2种,其中CEA、CYFRA21-1的灵敏度是5项肿瘤标志物中最高的2种.而通过联合5项肿瘤标志物对患者进行检测,可以使诊断结果更为准确,联合检测结果与单独检测的灵敏度、特异度比较,差异有统计学意义(P<0.05).结论 联合肿瘤标志物对肺癌患者进行诊断,可以在很大程度上提高诊断的灵敏度.%Objective To analyze the value of carbohydrate antigen(CA)153,CA125,neuron specific enolization enzyme(NSE) and carcinoembryonic antigen(CEA),cytokeratin(CYFRA)21-1 in the diagnosis of lung cancer.Methods From October 2014 to April 2016,60 patients were selected into lung cancer group,60 patients were selected into lung cancer group,60 healthy persons recruited into control group,blood specimens from all subjects received chemiluminescence immunoassay detection and analyzed.Results Five tumor markers for lung cancer detection had certain difference in sensitivity and specificity,the specific of NSE and CA153,the sensitivity of CEA and CYFRA21-1 in 5 tumor markers were the highest.The combination of 5 tumor markers could make the diagnosis of lung cancer more accurate,the differences of the specific and sensitivity between the combined detection and single detection were significant (P<0.05).Conclusion The combination detection of these five tumor markers could improve the diagnosis ability in patients with lung cancer.
