CD96 is reportedly enriched in tumor‐infiltrating T cells and NK cells in various cancers.[14, 15] However, the role of CD96 in solid tumor cells is hardly known.[16] Thus, we examined the expression pattern of CD96 in solid tumors using co‐immunofluorescence‐mediated evaluation of CD96 and various cell specific markers across 616 clinical samples from patients with BC (Table S1, Supporting Information). This evidence concerns the gene CD96 and breast cancer.
