Abstract：Objective To investigate the diagnostic value of combined detection of carcinoembry onic antigen (CEA), neuron-specific enolase (NSE), cytokeratin-19-fragment (CYFRA21-1), pro-gastrin-releasing peptide (ProGRP), and squamous cell carcinoma antigen (SCC-Ag) in lung cancer. Methods A total of 158 patients with lung cancer in the Chengdu First People′s Hospital from January to December 2017 were selected as lung cancer group(there were 51 cases of squamous cell carcinoma group, 72 cases of adenocarcinoma group and 35 cases of small cell carcinoma group), and 50 healthy persons during the same period were selected as health group. The levels of CEA, NSE, CYFRA21-1, ProGRP, and SCC-Ag in serum were detected respectively. Logistic regression receiver operating characteristic curve were applied to analyze the data and evaluate the diagnostic values. Results The concentrations of CEA, NSE, CYFRA21-1, ProGRP and SCC-Ag in lung cancer group were significantly higher than those in the healthy group (P < 0.01). The serum levels of NSE and ProGRP were the highest in small cell carcinoma group. The concentration of CEA was the highest in adenocarcinoma group, while that of SCC-Ag and CYFRA21-1 in squamous cell carcinoma group. The levels of five markers in lung cancer patients with stage Ⅲ-Ⅳ were significantly higher than those with stage Ⅰ-Ⅱ, the differences were statistically significant (P < 0.01). The area under the curve of combined detection Logistic regression model was 0.925, which was significantly higher than that of single test. Conclusion The combined of 5 serum tumor markers can improve the accuracy of lung cancer diagnosis.
