CD274 and neoplasm: We observed a numerically longer median RFS and OS among patients with high expression levels of PD-L1 (i.e., CPS ≥ 10) in tumor tissues than among those with low expression levels of PD-L1 (RFS: 26.9 vs 13.0 months, hazard ratio [HR]: 0.54 [95% CI: 0.214–1.361] [P = 0.203]; OS: 38.7 vs 21.8 months, HR: 0.57 [95% CI: 0.222–1.485] [P = 0.259]; Fig. 3A, B).
