Biomarkers in Tissue Samples From Patients With Newly Diagnosed Breast Cancer Treated With Zoledronic Acid
Estrogen Receptor-positive Breast Cancer, Invasive Ductal Breast Carcinoma, Progesterone Receptor-positive Breast Cancer
About this trial
This is an interventional treatment trial for Estrogen Receptor-positive Breast Cancer
Eligibility Criteria
Inclusion Criteria:
- Postmenopausal women
- Diagnosis of early stage, invasive ductal carcinoma (for which a lumpectomy or mastectomy is planned prior to systemic therapy)
- Estrogen receptor (ER)/progesterone receptor (PR) positive tumor (as confirmed by City of Hope Pathology Department if done on the outside) or
- Biopsy proven ER/PR positive tumor
- Ability to provide informed consent
Exclusion Criteria:
- Tumor that lacks both estrogen and progesterone receptors
- Patients who will receive neoadjuvant therapy prior to definitive surgery
- Bisphosphonate therapy currently or within the past 12 months
- Regular use of anti-inflammatory agents, with the exception of a baby aspirin regimen per principal investigator's (PI's) discretion
- Renal impairment as determined by a creatinine clearance < 60 ml/min as calculated by the Cockcroft-Gault formula using the patient's actual weight
- Current active dental problems including infection of the teeth or jawbone (maxilla or mandibular); dental or fixture trauma, or a current or prior diagnosis of osteonecrosis of the jaw (ONJ), of exposed bone in the mouth, or of slow healing after dental procedures
- Recent (within 6 weeks) or planned dental or jaw surgery (e.g. extraction, implants)

Arms of the Study
Arm 1
Experimental
Treatment (zoledronic acid)
Patients receive a single dose of zoledronic acid 4 mg IV over 15 minutes on day 1. Patients then undergo planned definitive surgery (lumpectomy or mastectomy) on day 10-23. Tissue and blood samples from the initial biopsy and definitive surgery are collected to measure changes in biomarkers of tumor growth and metastasis, immunologic function, and the expression of genes important to breast cancer progression and metastasis. zoledronic acid: Given IV laboratory biomarker analysis: Correlative studies therapeutic conventional surgery: Undergo definitive lumpectomy or mastectomy
