ERBB2 and neoplasm: The expression of FOXA1 was inversely associated with tumour size (P = 0.005), Nottingham Prognostic Index (P = 0.002), histological grade (P = 0.001), vascular invasion (P = 0.012), lymph node stage (P = 0.022) and HER-2 overexpression (P = 0.017), and was directly associated with ERα expression (P < 0.0001) and PR expression (P < 0.0001).
