We defined TILs using CD8 positivity only and found slightly higher levels in the HER2‐positive cohort C patients, but essentially low to intermediate numbers of TILs in the study population overall (mean 14.9%) The review by Pellegrino et al suggests that identifying TILs by FOXP3 positivity and CTLA‐4 expression in both tumor cells and TILs was associated with worse disease‐free and overall survival. This evidence concerns the gene CTLA4 and neoplasm.
