Value of combined detection of serum TSGF,NSE,CYFRA21-1,SCCAg in diagnosis of lung cancer / 国际检验医学杂志

ABSTRACT

Objective To investigate the clinical value of tumor specific grow th factor(TSGF),neuron specific enolase(NSE),cytokeratin 19 fragment(CYFRA21-1),squamous cell carcinoma antigen(SCCAg)in the diagnosis of lung cancer.Methods 20 patients with lung cancer,42 patients with lung benign diseases and 54 healthy people undergoing the physical examination in this hospital from September 2014 to November 2016 were served as the lung cancer group,benign diseases group and healthy control group respectively.The Abbott microparticle chemiluminescence instrument was used to detect CYFRA21-1 and SCCA levels,the Roche electrochemical luminescence instrument was used to detect the NSE level and the TSGF level was de-tected by using the Olympus 5400 biochemical analyzer.Then the detection results were statistically analyzed. Results The levels of serum TSGF and NSE in the lung cancer group were higher than those in the lung be-nign diseases group and healthy control group,and the differences were statistically significant(P< 0.05). The serum CYFRA21-1 level of the lung benign disease group was higher than that in the healthy control group(P<0.05).The sensitivity and specificity of TSGF,NSE,CYFRA21-1 and SCCAg combined detection were 90.00% and 93.00% respectively.The area under the ROC curve was 0.959.Conclusion TSGF posses-ses wide spectrum marker characteristics,has a certain value for screening lung cancer,moreover its combined detection with NSE,CYFRA21-1 and SCCAg can increase the accuracy in diagnosis of lung cancer.
