None of the glandular bladder tumours showed PD-L1 expression in tumour cells, but up to 45% (5/11) of BAC and 30% of UCg cases (3/10) showed PD-L1 expression in immune cells; thus, ICI might be a treatment option for a subset of advanced BAC and UCg. This evidence concerns the gene CD274 and urinary bladder neoplasm.
