The purpose of this study is to study the differences between CRT and SBRT. The investigator's are assessing radiation oncologists' decision-making during the evaluation of patients with spinal metastases by requesting radiation oncologists complete a questionnaire. Additionally, the investigator's will compare outcomes, including local progression, pain response and overall survival between SBRT and CRT. By collecting this information, the investigator's will develop an evidence-based algorithm that may be used to support medical decision-making for others with spinal metastases in the future.
This is a single institutional registry-based, prospective, observational study to describe radiation oncologists' decision making during evaluation of patients and to compare real-world outcomes of SBRT vs CRT.~A registry-based trial involves observing the effect of something without manipulating it.
