5项血清肿瘤标志物联合检测在肺癌诊断中的价值

目的检测肺癌及肺良性病变患者血清血清癌胚抗原(CEA)、神经元特异性烯醇化酶(NSE)、非小细胞肺癌相关抗原21-1(CYFRA21-1)、糖类抗原125(CA125)及铁蛋白(Fer)的水平,探讨其在肺癌诊断中的应用价值。方法采用电化学发光法检测103例肺癌和32例肺良性病变患者及40例健康人群血清中的CEA、NSE、CYFRA21-1、CA125及Fer水平,并进行比较。结果肺癌组CEA、NSE、CYFRA21-1、CA125及Fer的水平分别为(110.2±95.5)ng/mL、(50.6±43.4)ng/mL、(32.8±29.5)ng/L、(122.7±110.4)U/L、(854.6±497.2)ng/mL,明显高于对照组和肺良性病变组(t=6.21、5.71、6.75、6.62、7.74,P0.05;t=5.26、4.86、5.81、5.20、6.26,P0.05);CEA、NSE、CYFRA21-1、CA125及Fer诊断肺癌的灵敏度分别为39.81%、24.27%、71.84%、68.93%、77.66%,5项指标联合检测灵敏度为96.12%、特异度为95.00%。结论 5项肿瘤标记物联合检测能明显提高肺癌的检出率,有利于肺癌的早期诊断,可以广泛应用于临床中。

The clinical value of combined detection of five serum tumor markers in diagnosis of lung cancer

Objective To evaluate the clinical value of serum carcinoembryonic antigen(CEA),neuron specific enolization enzyme(NSE),21-1 non-small cell lung cancer associated antigen(CYFRA21-1),carbohydrate antigen 125(CA125) and ferritin(Fer) in the diagnosis of lung cancer.Methods The levels of CEA,NSE,CYFRA21-1,CA125 and Fer were measured by electrochemlium-inescence in 103 patients with lung cancer,32 patients with benign lung diseases and 40 healthy people.Results The serum levels of CEA,NSE,CYFRA21-1,CA125 and Fer in patients with lung cancer(110.2±95.5)ng/mL,(50.6±43.4)ng/mL,(32.8±29.5)ng/L,(122.7±110.4)U/L,(854.6±497.2)ng/mL] were significantly higher than those in patients with benign lung diseases and those in healthy people(t=6.21,5.71,6.75,6.62,7.74,P<0.05;t=5.26,4.86,5.81,5.20,6.26,P<0.05).The sensitivity values of CEA,NSE,CYFRA21-1,CA125,Fer and the combined determination containing five tumor markers were 39.81%,24.27%,71.84%,68.93%,77.66% respectively.The sensitivity and specificity of the combined determination containing five tumormarkers were 96.12%,95.00%.Conclusion The joint detection in the diagnosis of lung cancer could improve the sensitivity significantly,to help for early diagnosis of lung cancer,which is value to widely applied in clinic.
