CD274 and colorectal cancer: Positive PD-L1 status (HR=1.914, 95% CI:1.031-3.553, p=0.040), positive A2aR expression (HR=2.400, 95% CI: 1.264-4.558, p=0.007), distant metastasis (HR=15.151, 95% CI: 6.502-35.303, p<0.001), and TNM stage (HR=4.195, 95% CI: 1.869-9.415, p=0.001) could be independent prognostic predictors for colorectal cancer patients.
