Postoperative Edge (RapidArc) Stereotactic Body Radiotherapy for Spinal Metastases

NCT07801274 · Status: RECRUITING · Type: OBSERVATIONAL · Enrollment: 50

Last updated 2026-09-03

No results posted yet for this study

Summary

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.
