For patients with triple-negative breast cancer subtype (n = 39), FOXF2low patients had poorer 3-year DFS (P = 0.013), 5-year DFS (P = 0.002), and overall DFS (P = 0.002) than FOXF2high patients, whereas there was no significant correlation between DFS in patients with luminal and HER2+ breast cancer subtypes and FOXF2 mRNA expression levels (Fig. 1). Here, ERBB2 is linked to breast carcinoma.
