In a previous study, of 9321 colorectal cancer tumors, 1270 (13.6%) were HRD, and in the microsatellite‐stable/proficient mismatch repair (MSS/pMMR) subgroup, HRD tumors had a larger proportion of PD‐L1 positive tumors than non‐HRD tumors.35 This evidence concerns the gene CD274 and colorectal cancer.
