Risk Adapted Spinal Cord/Cauda Constraint Relaxation for High-risk Patients With Metastatic Epidural Spinal Cord Compression Undergoing Spine Stereotactic Radiosurgery
M.D. Anderson Cancer Center
Summary
To learn about the safety of a procedure called cord dose escalated spine stereotactic radiosurgery (CDE-SSRS) in patients with MESCC.
Description
Primary Objectives The primary protocol objectives are to establish the safety of CDE-SSRS alone in participants with MESCC. Specifically, we aim to maintain an RM risk no greater than 1%. RM will be defined as non-functional paresis per the McCormick score (i.e., Grade D). Secondary Objectives Secondary objectives include pain control as measured by the Brief Pain Inventory, quality of life as measured by the EQ-5D, symptom burden as measured by the MDASI-SP, overall survival, toxicity, ambulatory rate and cost-effectiveness. LC will be defined radiographically with serial MRI scans by the s…

Inclusion Criteria: 1. Greater than or equal to 18 years old 2. Radiographically documented spinal metastasis on spine MRI within 4 weeks of registration 3. Proximity of spinal metastasis to spinal cord or cauda equina which precludes achieving a GTV Dmin of at least 14 Gy per the PI 4. All participants must be able to receive single fraction SSRS at the site of interest with 0.01 cc of the spinal cord receiving 14-16 Gy and/or 0.01 cc of the cauda equina receiving 18-20 Gy. The goal of treatment is to select the minimal dose to the organ at risk which will achieve a GTV Dmin of 14 Gy at the…
