CD4 and non-small cell lung carcinoma: In multivariate Cox analysis, we found that ypTNM (p = 0.033, hazard ratio [HR] = 3.48, 95% confidence interval [CI]: 1.11–10.94), post‐chemotherapy TIL (p = 0.014, HR = 0.29, 95% CI: 0.10–0.91), and an increase in CD4+TIL levels post‐chemotherapy (p = 0.019, HR = 0.29, 95% CI: 0.10–0.81) were independent prognostic factors of NCT‐NSCLC (Table 2).
