Abstract

Purpose: The impact of neoadjuvant chemotherapy (NACT) on immunohistochemical markers in breast cancer specimens remains controversial. We designed the current study to investigate the potential changes in estrogen receptor (ER), progesterone receptor (PR), HER2, and Ki-67 expression before and after NACT in a cohort of Turkish patients with breast cancer.
