Study on the clinical value of chest CT and tumor markers in the early screening of lung cancer

Objective To discuss the clinical value of chest CT and tumor markers in the early screening of lung cancer.Methods There were 68 patients with lung cancer diagnosed by chest examination selected as the lung cancer group,and 68 healthy people in the same period as the healthy group.All patients underwent DR chest radiography and then chest CT scan.Comparison was made on the detection rate of lung cancer in DR and chest CT and the levels of tumor markers[carcinoembryonic antigen(CEA),carbohydrate antigen 211(CA211),neuron-specific enolase(NSE)]between the two groups.Results The detection rate of lung cancer in chest CT 97.1%was higher than 83.8%in DR,and the difference was statistically significant(P<0.05).The levels of CEA,CA211 and NSE of lung cancer patients were(8.33±2.75),(2.04±1.78)and(10.62±2.11)ng/ml,which were all higher than(2.85±1.32),(1.32±0.68)and(8.52±2.08)ng/ml of healthy group,and the difference was statistically significant(P<0.05).Conclusion Chest CT and tumor markers detection can effectively screen patients with early lung cancer,and treat them as soon as possible to improve the prognosis of lung cancer patients and increase survival rate,which can be used as an important basis for clinical diagnosis.
