Metastatic Epidural Spinal Cord Compression

This study observes the effectiveness of high-precision radiation therapy using the Edge system after surgery for patients with spinal metastases. Spinal metastases can press on the spinal cord and cause pain, weakness, or paralysis. This treatment uses higher doses of radiation in fewer sessions (hypofractionated stereotactic body radiotherapy) delivered precisely by the Edge machine to target remaining tumor cells while protecting the spinal cord. The study aims to see if this approach improves local tumor control, improves neurological function, shortens treatment duration, and improves quality of life in these patients. The study is observational, meaning patients receive standard care, and data is collected to evaluate the outcomes.

The purpose of this study is to see if treating cancer with radiation therapy administered by the Varian Ethos system can control patient's tumor and eliminate the need for surgery used to treat nerves in the spine flattened by pressure (compressed).
