Abstract:【Objective】 To investigate the prognostic value of combined detection of tumor-infiltrating CD3+ and CD4+ T cells and interleukin-17 (IL-17) in non-small cell lung cancer (NSCLC). 【Methods】 A total of 132 NSCLC patients who underwent radical lung cancer surgery in our hospital were followed up for 3 years postoperatively. Factors affecting patient prognosis and survival status were analyzed, and the expression levels of CD3+ and CD4+ T cells and IL-17 were compared between disease-free and recurrent patients, along with their relationship to prognosis. 【Results】 The counts of CD3+ and CD4+ T cells in the disease-free group were higher than those in the recurrence group (P<0.05), and the positive expression rate of IL-17 in the disease-free group was lower than that in the recurrence group (P<0.05). Multivariate logistic regression analysis showed that tumor staging, CD3+ and CD4+ cell counts, and IL-17 positivity were factors affecting disease-free survival in NSCLC patients (P<0.05). Receiver operating characteristic (ROC) curve analysis indicated that the sensitivity of CD3+ T cells, CD4+ T cells, IL-17, and their combination in predicting disease-free survival in NSCLC patients were 72.22%, 75.93%, 70.37%, and 81.48%, respectively, and the specificities were 73.44%, 71.88%, 70.31%, and 90.63%, respectively. The disease-free survival curves for patients with high expression of CD3+ and CD4+ T cells were better than those for patients with low expression (P<0.05), and the disease-free survival curve for the IL-17 negative expression group was better than that for the IL-17 positive expression group (P<0.05). 【Conclusion】 The CD3+ T cells, CD4+ T cells, and IL-17 are associated with the prognosis of NSCLC, and the combined prediction of these three markers has good prognostic value. Patients with low expression of CD3+ and CD4+ T cells and positive expression of IL-17 have a higher risk of poor prognosis.
