简要总结
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.
详细描述
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

结局指标
主要结局
Initial Symptom Control
时间窗: 6 weeks post-SBRT (or at first post-treatment follow-up)
Evaluation of pain relief per patient report
Local Tumor Recurrence Rate
时间窗: (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.
次要结局
- Late Toxicity Rate(at patient's last follow-up (at least 3 months from treatment) or time of death)
