Brief Summary
This pilot clinical trial studies biomarkers in tissue samples from patients with newly diagnosed breast cancer treated with zoledronic acid (ZA). Studying samples of tumor tissue in the laboratory from patients receiving ZA may help doctors learn more about the effects of ZA on cells. It may also help doctors understand how well patients respond to treatment.

Outcome Measures
Primary Outcomes (1)
Mean (SE) Change From Pre-Treatment Baseline in (Log)pg/mL of Biomarker, by Time, Adjusted for Level at Baseline
After the trial's premature closure, no data were collected for the primary endpoints; however, data on 14 of 30 secondary endpoints were obtained and are summarized below. Serum level (pg/mL) per biomarker was log-transformed. Change from baseline over time was evaluated using a generalized linear mixed model where follow-up time was represented by terms for the sequence of post-baseline samples or for (log)day on study. To recognize regression to the mean across repeated samples, a term for biomarker level at baseline, with or without interaction by time, was included when it improved the model's fit to the observed data. With 14 biomarkers sampled twice after baseline, there were 28 evaluations of change in biomarker level with exposure to study drug. Therefore, to control the False Discovery Rate (FDR), only evaluations that maintained the study's FDR at no more than 5 percent were accepted as true.
"48-72 hrs" and "Surgery (10-23 days)"
Study Arms (1)
Treatment (zoledronic acid)
EXPERIMENTALPatients 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
Interventions

Undergo definitive lumpectomy or mastectomy
Eligibility Criteria
You may qualify if:
- 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
You may not qualify if:
- 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)
