Patients with estrogen receptor positive (ER+) and/or progesterone receptor positive (PR+) breast cancer do not achieve good responses with pre-operative chemotherapy. The sensitivity of breast cancer to chemotherapy is often determined by the underlying gene expression pattern and the molecular subtype of the tumor. In addition, not all patients tolerate chemotherapy well. Pre-operative endocrine therapy has emerged as an effective strategy to improve outcomes in patients with early-stage hormone receptor positive breast cancer. This study will assess the role of neo-adjuvant palbociclib (CDK 4/6 inhibitor) in combination with letrozole (aromatase inhibitor) +/-Goserelin (GnRH analogue) to improve overall response and surgical feasibility in post and pre-menopausal hormone receptor positive and Her-2 negative subjects with stage IIA-IIIC breast cancer.
