We previously investigated the prognostic value of HRs in patients with IBC who underwent neoadjuvant chemotherapy (NAC) and found that HR positivity had no prognostic value for survival after NAC among HR-positive (HR+)/human epidermal growth factor receptor 2–positive (HER2+), HR+/HER2-negative (HER2−), and HR-negative (HR−)/HER2+ subtypes [8]. The gene discussed is ERBB2; the disease is inflammatory breast carcinoma.
