Kaplan‐Meier survival analysis demonstrated that high expression of tumor‐intrinsic PD‐1, determined by IHC staining, was significantly associated with shorter OS (20.0 months vs. N.A., p = 0.017, HR = 3.093, 95% CI: 0.989‐9.672, Figure S1A, Supporting Information) and reduced RFS (9.0 months vs. 29.0 months, p = 0.003, HR = 3.463, 95% CI: 1.278‐9.385, Figure S1B, Supporting Information). This evidence concerns the gene PDCD1 and neoplasm.
