Breast Cancer | Research of Zoledronic Acid and Aromatase Inhibitors as Adjuvant Therapy to Breast Cancer

Breast Cancer research study

What is the primary objective of this study?

Select patients of primary breast cancer whose hormone receptor is positive and accepted postoperative adjuvant aromatase inhibitors for endocrine treatment.Treat them with zoledronic acid 4mg intravenous infusion every six months until the end of the aromatase treatment. Assess the disease-free survival; overall survival; combination of security, as well as the situation of bone loss.
