Accordingly, in the KM plotter database, we found that high NDRG1 expression correlated with less relapse-free survival (RFS) in all cases of breast cancer (HR: 1.42; p= 1.6×10-11), luminal B (HR: 1.27; p=0.008), basal-like (according to StGallen guidelines) (HR: 1.58; p=6.6×10-5) and TNBC (ER-, PR-, HER2-) (HR: 1.64; p=0.008) (Fig. 1A; Fig. S1A). Here, ERBB2 is linked to breast cancer.
