Abstract

Objective To explore the diagnostic value and application effect of the combined detection of CEA (carcinoembryonic antigen), SCC (squamous cell carcinoma antigen), CYFRA21-1 (soluble fragment of cytokeratin 19), NSE (neuron specific enolase) and proGRP (gastrin releasing peptide precursor) in early lung cancer. Method 66 patients who admitted to the hospital from April 2019 to February 2024 were selected as the early stage lung cancer group and the other 159 patients were selected as the benign lung group, in which all subjects were tested for NSE, CEA, ProGRP, CYFRA21-1, and SCC levels and were confirmed by histopathological analysis. In ROC analysis, the cut-off point, AUC, accuracy, sensitivity and specificity between single and combined detection indicators are analyzed. Result The size of cut-off point, AUC, accuracy, sensitivity, specificity, positive and negative detection rate and accuracy rate is 0.3072, 0.790, 89.33%, 0.894, 0.893, 89.40% (59/66), 89.31% (142/159) and 89.33% ((142+59)/225) respectively and it is obviously superior to those of single detection method. Meanwhile, indicator of SCC showed the worst performance by single detection. Conclusion The combined detection indicators have high diagnostic value in early diagnosis of lung cancer, and the sensitivity, positive detection rate, AUC value and accuracy have been significantly improved.
