%X Aim: To evaluate the value of combined detection of plasma cfDNA concentration and integrity in the early diagnosis of NSCLC. Methods: Real-time fluorescence quantitative PCR was used to determine the concentration and integrity of plasma cfDNA in 71 NSCLC patients and 53 healthy people. Results: Combined detection of plasma cfDNA concentration and integrity had higher diagnostic power in differentiating NSCLC patients with stage I/II from healthy people than detection of plasma cfDNA concentration alone or integrity alone. The AUC, sensitivity and specificity of the combined detection of plasma cfDNA concentration and integrity were 0.781, 0.62 and 0.85. Conclusion: Combined detection of plasma cfDNA concentration and integrity could improve the diagnostic value in NSCLC detection.<BR>The discovery of cfDNA has opened up a wide range of new possibilities for the diagnosis of cancer. CfDNA provides a noninvasive diagnostic approach for early screening, early detection and monitoring of patients with cancer. Currently, the application of cfDNA in clinical practice for NSCLC patients has been widely reported, which mainly focused on DNA methylation detection, oncogenic driver gene mutation detection. However, few studies have evaluated the diagnostic value of combined detection of plasma cfDNA concentration and integrity for NSCLC patients. Our study suggests that the combination of plasma cfDNA concentration and integrity has higher AUC value in differentiating NSCLC patients from healthy individuals than plasma cfDNA concentration alone or integrity alone.
