The clinical significance of the different IPs is as follows: (1) high-TIL counts in the TC represented the most robust indicator for LPBC, with a high proportion of CD8+ T cells, indicating favorable DFS in TNBC; (2) high PIL counts with a high proportion of CD20+ B cells indicated poor DFS similar to TILs mainly in the IM in luminal B subtype IBC; (3) PD-L1 positivity significantly correlated with the IC counts and could be predicted by IPs; and (4) IPs of IBC-NST might be a potential prognosis factor, especially in the TNBC and luminal B subtypes. The gene discussed is CD274; the disease is inflammatory breast carcinoma.
