ERBB2 and breast neoplasm: As can be seen in Fig 4, high expression of NCOR1 is associated with better relapse free survival in all breast cancer subtypes, including the luminal A subtype: all breast tumors (HR: 0.7, CI: 0.62–0.78; log rank p = 9e-11); luminal B (HR: 0.81, CI: 0.67–0.99; log rank p = 0.04); basal (HR: 0.73, CI: 0.57–0.94; log rank p = 0.016); HER2 (HR:0.72, CI: 0.49–1.05; log rank p = 0.085) and luminal A (HR:0.69, CI: 0.58–0.82; log rank p = 2e-05) (Fig 4A–4E).
