One-Time radiation blast aims to relieve spinal cord pressure from cancer

NCT ID NCT01254903

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing This study
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

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
