Decreased lncRNA ST7-AS1 expression in BRC was significantly correlated with pathologic stage (OR = 0.74 for Stage III/IV vs. Stage I/II, p = 0.04), HER2 status (OR = 0.58 for positive vs. negative, p = 0.003), and histological type (OR = 2.38 for infiltrating lobular carcinoma vs. infiltrating ductal carcinoma, p < 0.001) (Table 2). Here, ERBB2 is linked to invasive ductal breast carcinoma.
