In each breast cancer subtype, the proportion of unstained TILs tended to be higher in patients with TNBC than in other breast cancer subtypes (p=0.055), but there was no relationship between CD8+ TILs and FOXP3+ TILs and breast cancer subtypes (p=0.838 and p=0.570, respectively). The gene discussed is CD8A; the disease is breast cancer.
