However, there was a statistical trend toward higher frequency and MFI in CD3 + TILs expressing ICs in CMS1 (containing mainly MSI tumors) versus the other subgroups (significant for Tim-3 (Dunn’s multiple comparisons test, p = 0.0382) and TIGIT (Kruskal–Wallis test, p = 0.0446)) ( Figure S3A,B ).
We observed an overall trend towards an increase in all five ICs in stage II CRC and a decrease in stage III, although these trends were not statistically significant (except for Tim-3 in terms of frequency, p = 0.011), probably due to the high inter-patient variability within the pTNM stages.
