Zoledronate in Preventing Bone Loss in Postmenopausal Women Who Are Receiving Letrozole for Stage I, Stage II, or Stage IIIA Breast Cancer

Summary

RATIONALE: Estrogen can cause the growth of breast cancer cells. Hormone therapy using letrozole may fight breast cancer by lowering the amount of estrogen the body makes. Zoledronate may prevent bone loss in patients who are receiving letrozole. It is not yet known which schedule of zoledronate is more effective in preventing bone loss in patients with breast cancer. PURPOSE: This randomized phase III trial is studying two different schedules of zoledronate to compare how well they work in preventing bone loss in postmenopausal women who are receiving letrozole for stage I, stage II, or stage IIIA breast cancer.
