One-Time radiation blast aims to relieve spinal cord pressure from cancer
NCT ID NCT01254903
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-phase study tests whether a single, precise session of radiation (spine stereotactic radiosurgery) can safely treat spinal cord compression caused by cancer that has spread to the spine. The study includes 43 adults with inoperable tumors pressing on the spinal cord. Researchers will monitor how many patients remain able to walk and whether any develop radiation-related spinal cord injury.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Greater than or equal to 18 years old 2. Radiographically documented metastatic epidural compression on spine Magnetic resonance imaging (MRI) within 4 weeks of registration, defined radiographically, ranging from minimal canal compromise and thecal indentation to actual displacement of the spinal cord. 3. Maximum of 3 contiguous vertebral levels involved with metastasis in the spine to be irradiated in a single session 4. Signed Informed consent 5. Diagnosis of cancer (not one of the more radiosensitive histologies, see exclusion criteria) including but not limited to non-small cell lung cancer, breast, prostate, renal cell, melanoma, gastrointestinal, sarcoma, thyroid, head and neck primary, and unknown primary tumors 6. Motor Strength \>/= 4 out of 5 in extremity or extremities affected by the level of the spinal cord compression 7. Karnofsky performance status (KPS) \>/= 40 8. Patients deemed to be inoperable by patient refusal, by neurosurgical evaluation, or for any reason Exclusion Criteria: 1. Patient with radiosensitive histologies (lymphoma, multiple myeloma, small cell carcinoma, germ cell tumors) as conventional radiation is likely to be effective 2. Prior irradiation of the spine site and level to be treated 3. Inability to tolerate lying flat on treatment table for greater than 30 minutes. 4. Patients unable to undergo MRI of the spine 5. Patients who are pregnant 6. Patients who have cord compression from bone components or configuration
