Summary
Brief summary (as posted)
The purpose of this study is to test the safety of stereotactic body radiation therapy (SBRT) followed by surgical stabilization within 1 week. All participants will have metastatic cancer in the bone (bone metastases), and they will be at risk of pathologic fracture (broken bone caused by a disease). Another purpose of this study is to see if the treatment approach of SBRT followed by surgical stabilization within 1 week prevents cancer from returning to the bone.

- Preoperative Stereotactic Body Radiotherapy (SBRT)
- description
- Target lesions will be treated with preoperative SBRT consisting of biologically effective dose (BED10) of 50.4 - 81.6 Gy delivered in either three fractions or a single fraction. Active sparing of the intended surgical approach will be incorporated into the radiation plan by creating an avoidance structure. Surgical stabilization will proceed within 1 week of completion of radiotherapy. Pathologic specimens will be obtained intraoperatively via existing surgical access for histologic and molecular analysis. An optional research MRI with perfusion will be performed within 30 days prior to radiation simulation and within one-week after radiation therapy using 3T scanner. If patients receive radiation simulation at a non-MSK Manhattan site, MRI with Perfusion will not be performed.
