Differential protein expressions in colorectal tumors with different microsatellite instability status

All biomarkers were evaluated using immunohistochemistry

LS Lynch syndrome, MGMT O6-methylguanine DNA methyltransferase, MSI microsatellite instability, H high, Negative low or stable, n/a not available, PD-1 programmed cell death protein 1, PD-L1 programmed-death ligand 1, Topo1 topoisomerase 1, TS thymidylate synthase

p values were calculated using Fisher-Exact two tail tests
