Zometa and Circulating Vascular Endothelial Growth Factor (VEGF) in Breast Cancer Patients With Bone Metastasis

Summary

The primary objective of this study is to evaluate the effects of Zometa (zoledronic acid, 1 mg per week versus 4 mg every four weeks) on the circulating vascular endothelial growth factor (VEGF) levels in breast cancer patients with bone metastases. Sixty patients will be randomized into two groups.
