Membranous tumoral PD‐L1 expression was identified in 9 of 100 (9%) CRC cases, including 1 of 34 (2.9%) RC cases, but PD‐L1 immunopositivity was not associated with any clinicopathological factors, with the exception of deficient mismatch repair (dMMR) status. This evidence concerns the gene CD274 and colorectal carcinoma.
