PD-L1 showed significant prognostic value in bladder carcinoma (BLCA, HR=0.37, p=1.3e-05), breast carcinoma (HR=0.5, p=0.0011), esophageal squamous cell carcinoma (ESCC, HR=0.17, p=0.01), OV (HR=0.48, p=3.2e-05), PAAD (HR=1.7, p=0.046), pheochromocytoma and paraganglioma (PCPG, p=0.013), STAD (HR=0.51, p=0.014), KIRC (HR=0.61, p=0.0027) and UCEC (HR=0.44, p=0.026). Here, CD274 is linked to urinary bladder carcinoma.
