Eligible breast cancer patients with bone metastases will be treated with FSRT. 9-10 Gy x 3Fx or 6-7 Gy x 5Fx image-guided fractionated stereotatic radiation therapy will be used.
Fractionated stereotatic radiation therapy (FSRT) that very precisely delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. The purpose of this study is to find out if FSRT is safe and effective in the treatment of metastatic spinal tumors of breast cancer.
