Although, it has also been shown that when positive PD-L1 expression was assessed using the combined positive score (CPS ≥10) defined as the number of PD-L1 staining cells (tumor cells, macrophages, and lymphocytes) divided by the total number of viable tumor cells and multiplied by 100, PD-L1 positivity was found in 40.0% (2/5) of MPUC and in 100.0% (5/5) of UCSD [22]. Here, CD274 is linked to neoplasm.
