Abstract:

Objective

To explore the value of serum tumor markers ProGRP, carcinoembryonic antigen (CEA), cytokeratin 19 fragment (CYFRA211), neuron specific enolase (NSE), carbohydrate antigen 199 (CA199) and alpha fetoprotein (AFP) in diagnosis of lung cancer.

Methods

Serum samples from 560 patients were collected in Third Peoples Hospital of Kunming City during October 2016 to September 2017. Among them, 280 cases were lung cancer, 180 cases were benign lung disease and 100 cases were routine physical examination. The six tumor markers mentioned above in serum were detected by electrochemiluminescence immunoassay.

Results

The levels of ProGRP, CYFRA211, NSE, CEA and CA199 in lung cancer group were significantly higher than those in benign lung disease group and normal control group (χ2=401.251, 25.475, 35.292, 37.491 and 13.472, P<0.01, respectively). The serum levels of ProGRP, CYFRA211, NSE and CEA in small cell lung cancer group, adenocarcinoma group and squamous cell cancer group were significantly different (χ2=365.073, 15.657, 37.971 and 13.437, P<0.01, respectively). The sensitivity of combined detection of ProGRP and NSE in small cell lung cancer is 97.9%. The sensitivity of combined detection of CEA, CYFRA211 and NSE in adenocarcinoma was 87.7%.

Conclusion

The combined detection of serum tumor markers ProGRP, CEA, CYFRA211, NSE, CA199 and AFP has high clinical value for the diagnosis and monitoring of the curative effect of lung cancer. Combined detection of these markers can further improve the sensitivity and specificity.
