Objective To investigate the risk factors associated with clinical stage in patients with non-small cell lung cancer(NSCLC).Methods The clinical data of 182 patients with non-small cell lung cancer admitted from July 2019 to March 2023 were retrospectively analyzed,and they were divided into stage Ⅰ,stage Ⅱ group(n=73)and stage Ⅲ,stage Ⅳ group(n=109)according to the clinical stage.Inter-group comparison and Logistic regression analysis were used to screen the risk factors affecting the clinical stage of patients,and receiver operating characteristic(ROC)curve was used to analyze the diagnostic value of these risk factors.Results Antinuclear antibody(ANA),fibrinogen(FIB)and cytokeratin 19 fragment(CYFRA21-1)were independent risk factors affecting the clinical stage of NSCLC patients.The optimal cut-off values of FIB and CYFRA21-1 were 4.07g/L and 7.07μg/L,respectively.The area under curve(AUC)of the combined diagnosis of clinical stage was 0.859,the sensitivity was 64.2％,and the specificity was 95.9％.Conclusion ANA,FIB and CYFRA21-1 are independent risk factors for the progression of clinical stage of NSCLC patients.The combined detection of the three indicators has certain reference value for the diagnosis of clinical stage in NSCLC patients.

Lung cancer is one of the most important malignant tumors of human health and life in the world, and is the leading cause of death in the world. At present, it is believed that it is caused by many factors. Circular RNA (circRNA), as a class of non-coding RNA family, has covalently closed loop structure. CircRNA is abundant in different cells. CircRNAs due to the special structure, with a high degree of specificity, conservation and stability, may have a potential clinical value in the development of lung cancer. The biological function of circRNA is multi-faceted, including miRNA sponge, transcriptional and alternative splicing, protein coding , and so on. Currently, the role and mechanism of circRNA in lung cancer is not very clear. In this paper, the characteristics, function, mechanism and the role of circRNAs in the occurrence and development of lung cancer are reviewed.
