Abstract:

Objective

To evaluate the application of CEA, CA125 and cytokeratin 19 fragments (CYFRA21-1) in the diagnosis, pathological types and TNM stages of lung cancer.

Methods

It was collected 288 cases of hospitalized patients clinical data in Tang Du hospitals between January 2017 and April 2018. The concentrations of tumor markers in serum were detected by electrochemical immunofluorescence.It was analyzed the relationship between CEA, CA125 and CYFRA21-1 which were about lung cancer diagnosis, pathological types and TNM stages.

Results

Serum levels of CEA, CA125 and CYFRA21-1 in the lung cancer group were higher than those in the benign lung lesions group. CYFRA21-1 is the most valuable single tumor marker in different pathological types of lung cancer. The positive rates and serum levels of CEA and CA125 were of high application value in different TNM stages of lung cancer. Serum levels of CEA, CA125 and CYFRA21-1 are of great value in the early and late differentiation of lung cancer.

Conclusion

The CEA, CA125 and CYFRA21-1 are significant in the diagnosis of lung cancer. Among different pathological types, CYFRA21-1 is of great diagnostic value. The CEA, CA125 and CYFRA21-1 have different diagnostic values in TNM stage of lung cancer.

Key words: Bronchogenic lung cancer, Lung tumor markers, TNM staging
