In this study, Data of 100 patients with spinal metastatic tumor who received stereotactic radiotherapy or conventionally-fractionated image-guided intensity-modulated radiotherapy in the multi-center of the research group from July 2019 to June 2021 will be collected, as well as their follow-up data.The metastases were treated with SBRT.Using multimodal image fusion to outline the target area.PTV = GTV + 0-10mm Target volume radiation dose: The range of BED value of radiotherapy was 60-72 when the distance between the tumor and gastrointestinal tract or spinal cord was more than 5 mm (alpha/beta=10) and 51.3-59.5 when the distance between the tumor and gastrointestinal tract or spinal cord was less than 5 mm (alpha/beta=10).The metastases were treated with Conventionally-fractionated image- guided Intensity modulated radiotherapy.Using multimodal image fusion to outline the target area.The dose of the target volume radiotherapy dose is 30 Gy/10f or 40Gy/20f.Previous treatment and follow-up data will be analyzed to evaluate the clinical efficacy comparison of stereotactic radiotherapy and conventionally-fractionated image-guided intensity-modulated radiotherapy for spinal metastatic tumors, local control rate and side effects, and to clarify the effectiveness and safety of different doses of radiotherapy.
