Objective: To investigate the effect of neoadjuvant chemotherapy on estrogen receptor (ER) and progesterone receptor (PR) expression in breast carcinoma.
Methods: Samples were obtained from 31 patients with breast carcinoma who received neo-adjuvant chemotherapy, ER or PR expressions were analyzed in preoperative core biopsies and final surgical specimens.
Results: ER level was up-regulated in 13 (41.9%) out of 31 cases, PR level was up-regulated in 10 (32.3%). Both ER level and PR level were up-regulated in 8 (25.8%) out of 31 cases.
Conclusions: Neoadjuvant chemotherapy may impact the hormone receptor status, ER and PR expression re-analysis in final surgical specimens is recommended.
