Immunohistochemical TACC2 status was significantly associated with Ki‐67 LI (P = 0.047), but no significant association was detected between TACC2 status and other clinicopathological parameters examined, such as patients’ age, menopausal status, stage, status of neoadjuvant chemotherapy, pathological tumor factor (pT), lymph node metastasis, histological grade, ER status, PR status, AR status, and HER2 status. Here, ERBB2 is linked to neoplasm.
