Table 3 and Table 4 show the OS and RFS results of the PD-L1-positive group obtained via univariate and multivariate analyses (Table S2 summarizes the analysis by GZMB cut off value (1% or 5%). In the univariate analysis, GZMB, tumor diameter, and lymph nodes were associated with OS and RFS. In the multivariate analysis, GZMB was independently associated with RFS and OS (RFS: hazard ratio (HR) = 0.21, 95% confidence interval (CI) 0.07–0.69, p = 0.009; OS: HR = 0.25, 95% CI 0.69, p = 0.009; HR CI 0.07–0.88, p = 0.03). This evidence concerns the gene CD274 and neoplasm.
