Although the reactivities of the labeled antibodies were not always the same, and a direct comparison was not possible, a similar distribution of the leukocyte infiltrations was observed in the tumor tissue in our study and a previous study with a distribution median of 218 CD45+ TIL/mg of tumor tissue (interquartile range: 85–445 CD45+ TIL/mg)32. This evidence concerns the gene PTPRC and neoplasm.
