Meanwhile, in order to exclude the influence of follow‐up treatment, we reanalyzed the prognostic value of various TIL after eliminating the patients who received subsequent epidermal growth factor receptor or anaplastic lymphoma kinase tyrosine kinase inhibitor treatment because of the important influence on OS, and the result was consistent with that of all patients (Figures S2 and S3), which also illustrated that the TIL is independent prognostic factor of OS for NSC‐NSCLC. The gene discussed is EGFR; the disease is non-small cell lung carcinoma.
