Pilot Study to Investigate the Metabolic Pathways in Hormone Receptor Positive/HER2 Negative Breast Cancer
To analyze the metabolic activity of Hormone Receptor Positive (HR+)/Her 2 Negative (Her2-) Breast cancer.
• Have hormone receptor (HR) positive \[estrogen receptor( ER)+/progesterone receptor (PR)+, ER+/PR- or ER-/PR+)/Her2 negative breast cancer previously diagnosed by biopsy.
• Have early stage, clinical or anatomic stage I, II or III breast cancer (cT1cN0, cT1cN1, cT2N0, cT2N1, cT3N0)
• Candidates for intended curative primary resection who have not had neoadjuvant therapy (endocrine/hormonal therapy, chemotherapy with or without immunotherapy).
• Willing to undergo mandatory intraoperative small excisional and core biopsies (4-6 passes) of tumor and normal tissue for research purposes at the time of proposed surgical resection.
