Abstract
Objective:To discuss the diagnostic value of combined detection of CYFRA21-1,CEA, NSE and CA125 in non small cell lung cancer.Method:92 cases of NSCLC and 95 cases of lung benign lesions from January 2010 to June 2015 in our hospital were selected as the research objects,92 cases of NSCLC were divided into 42 cases of lung squamous cell carcinoma group and 50 cases of lung adenocarcinoma group according to the different pathological types.The levels of CYFRA21-1, CEA, NSE and CA125 in all patients were measured by electrochemical luminescence method.Result:The CYFRA21-1,CEA,NSE and CA125 in NSCLC group were significantly higher than those in benign lung disease group,the differences were statistically significant (P<0.05).The sensitivity and specificity of CYFRA21-1 were respectively 71.40% and 89.10% in lung squamous cell carcinoma group,the sensitivity and specificity of CEA were respectively 60.00% and 84.30% in lung adenocarcinoma group.The sensitivity of CYFRA21-1 in the diagnosis of NSCLC was 46.53%,specificity was 85.26%.The sensitivity of CEA in the diagnosis of NSCLC was 42.58%,specificity was 81.05%.The sensitivity of NSE in the diagnosis of NSCLC was 57.43%,specificity was 76.85%.The sensitivity of CA125 in the diagnosis of NSCLC was 48.51%,specificity was 66.32%.Combined determination of the four parameters sensitivity was 93.26%,specificity was 98.25%.Conclusion:CYFRA21-1,CEA,CA125 and NSE have certain value for the early detection and diagnosis of NSCLC,and the combined detection of the four has obvious complementarity, which can significantly improve the diagnostic rate of NSCLC.关键词
