In the total IBC cohort, only distant disease at diagnosis (HR 3.06, 95%CI 1.79–5.22, P < 0.001), sTIL infiltration (HR 0.46, 95%CI 0.27–0.81, P = 0.006) and nodal status (HR 1.64, 95%CI 1.14–2.35, P = 0.008) remained significant predictors for OS. This evidence concerns the gene STIL and inflammatory breast carcinoma.
