Prognostic implication of programmed cell death 1 protein and its ligand expressions in endometrial cancer

Monoclonal antibodies targeting programmed cell death-1 (PD-1)/programmed death ligand 1 (PD-L1) demonstrated promising clinical response. The predictive/prognostic value of PD-1/PD-L1 immunohistochemistry (IHC) has been evaluated in many cancer types. However, the prognostic value of PD-1/PD-L1 IHC has not been evaluated in endometrial cancer.We conducted a retrospective study to quantify the IHC CD8, PD-1, and PD-L1 expressions in immune cells...
