Chintakuntlawar et al. [34] also investigated the prognostic value of the immune checkpoints programmed death-1 (PD-1) and its ligand (PD-L1) in these tumours and verified that PD-1 and PD-L1 are both highly expressed in ATC and are associated with shorter progression-free survival and overall survival in multimodality-treated patients. Here, CD274 is linked to neoplasm.
