(44) reported that PD-L1 expression in tumor cells (PD-L1 (T))-positive MSI-H CRCs did not correlate with budding graded 2 or 3 (p = 0.34); however, PD-L1 expression in tumor-infiltrating myeloid cells in stroma (PD-L1 (I))-positive MSI-H colorectal cancers significantly correlated with budding grades 2 or grade 3 (p = 0.043). Here, CD274 is linked to colorectal cancer.
