C-Index values were higher in TNBC (RCB: 0.73, 9CI [0.68–0.77]; Neo-Bioscore: 0.71, CI [0.66–0.75]) and HER2-positive tumours (RCB: 0.64, CI [0.56–0.73]; Neo-Bioscore: 0.64, CI [0.56–0.73]) compared to luminal tumours (RCB: 0.61, CI [0.55–0.67], and Neo-Bioscore: 0.60, CI [0.53–0.67]) (Fig. 2e-h). This evidence concerns the gene ERBB2 and neoplasm.
