|Condition or disease||Intervention/treatment||Phase|
|Breast Cancer||Drug: leuprolide Drug: letrozole Drug: zoledronic acid||Phase 2|
- Participants will be given a monthly intramuscular injection of leuprolide. Six to eight weeks after the first leuprolide injection, participants will be instructed to begin taking letrozole pills by mouth at home each day.
- During this research study, participants will also be offered injections of zoledronic acid to preserve bone mineral density. If desire, these injections will be given every 6 months for a total of 4 injections during the course of the research study.
- The treatments in this research study may increase the risk of bone density loss, so vitamin D and calcium supplements will be recommended to participants.
- The following tests and procedures will be performed during the research study: Physical Exam (every visit); Blood tests; Urine test (beginning and end of treatment); Imaging (annual mammograms); Bone Density (DXA) Scan (beginning and end of treatment); Questionnaires (throughout the study).
- Participants will be on this study for about two years.

- Tolerability at One Year of Ovarian Function Suppression (OFS) Using Leuprolide and Letrozole. [ Time Frame: 1 year ]The tolerability at one year of ovarian function suppression (OFS) using leuprolide and letrozole in this patient population. Specifically, the number of patients who discontinued treatment prior to one year due to toxicity.
- Ovarian Function Suppression (OFS) Combined With Aromatase Inhibition Combined With Intravenous Bisphosphonate Therapy on Bone Mineral Density. [ Time Frame: 2 years ]Ovarian function suppression (OFS) combined with aromatase inhibition combined with intravenous bisphosphonate therapy on bone mineral density in this patient population.
- The Effect of OFS Combined With Aromatase Inhibitor Therapy on the Incidence and Severity of Menopausal Symptoms, Sexual Dysfunction, Musculoskeletal Complaints, Other Side Effects and Overall Quality of Life. [ Time Frame: 2 years ]OFS combined with aromatase inhibitor therapy on the incidence and severity of menopausal symptoms, sexual dysfunction, musculoskeletal complaints, other side effects and overall quality of life in this population.
