Overview
Brief Summary
This study will evaluate the local control rate as well as acute and late toxicity rates of stereotactic body radiotherapy (SBRT) for the treatment of spine metastases and benign spine tumors.
Detailed Description
This study is a single site, non-randomized, prospective, phase IV trial. Patients are composed of 2 groups:Spine Metastases OR Benign Spine Tumors. Data collected will include patient demographics, pathology data, tumor stage, SBRT dose fractionation scheme, dose received by adjacent critical normal tissues, tumor recurrence data, and acute and late toxicities. Follow up data will be collected during the patient's standard office visits. The anticipated duration of this study is 5 years

Eligibility Criteria
Inclusion Criteria
- Not provided
Exclusion Criteria
- •Lesion involving \> 3 adjacent vertebral levels
- •Overt spinal instability
- •Neurologic deficit due to bony fragments/bony compression of neural structures
- •Prior radiotherapy at the involved level(s) within 3 months of radiosurgery, more than one prior course of radiotherapy at the involved level(s), or more than 45 Gy previous radiation exposure at the involved level(s)
- •Rapidly progressive spinal cord compromise or neurological deficit
- •Paralysis, or otherwise compromised motor function due to radiographically confirmed cord compression
- •Patient unable to undergo an MRI
- •Pregnant or lactating women, due to potential exposure of the fetus to RT and unknown effects of RT on lactating females
- •Patients with psychiatric or addictive disorder that would preclude obtaining informed consent
Outcomes
Primary Outcomes
Initial Symptom Control
Time Frame: 6 weeks post-SBRT (or at first post-treatment follow-up)
Evaluation of pain relief per patient report
Local Tumor Recurrence Rate
Time Frame: (1) At 1 year post-SBRT, (2) At patient's last follow-up or time of death
Local recurrence is defined as tumor recurrence or progression within the planning target volume. Local control rate will be evaluated by imaging techniques and/or clinical symptoms (worsening or no improvement in pain or neurologic compromise). If follow-up imaging is available, a local recurrence will be defined as an increase of \> 20% in tumor size.
Secondary Outcomes
- Late Toxicity Rate(at patient's last follow-up (at least 3 months from treatment) or time of death)
