CD274 and neoplasm: Multivariable Cox regression analyses showed that tumor category pT4 (hazard ratio [HR] = 2.23; 95% confidence interval [CI]: 1.278–2.3.896; P = 0.005), positive LNs (HR = 1.79; 95% CI: 1.083–3.232; P = 0.021), and positive PD-L1 on TIICs (HR = 2.03; 95% CI: 1.186–3.461; P = 0.010) were significantly associated with an increased risk of tumor recurrence.
