Brief Summary

The goal of this clinical study is to learn the feasibility of using a single session of radiation, known as spine stereotactic radiosurgery (SSRS), to treat metastatic epidural spinal cord compression.

Detailed Description

Spinal cord compression is often treated with surgery followed by radiation in small doses everyday for a number of days. When a patient cannot or will not have surgery, radiation is given daily. With increased accuracy and precision, higher doses of radiation can be given in a single session. Giving a higher dose in a single session may increase the chance that the tumor will stop growing into the spinal canal and will prevent spinal cord injury. This study will also help to identify the tolerance of the spinal cord to radiation in a single session.

Spine Stereotactic Radiosurgery:

You will lie in the mold that was made for you for 45-120 minutes while you receive your radiation treatment.

Follow-up Visits:

You will have follow-up visits at Months 3 (+/-2 weeks ), 6 (+/-4 weeks), 9 (+/-4 weeks), 12 (+/-8 weeks), 18 (+/-8 weeks), and 24 (+/-8 weeks) and then every 6 months after that. At each follow-up visit:

• Your medical history will be recorded, including any use of steroids.
• You will have a neurological exam.
• You will complete the 3 questionnaires about health, symptoms you may be having, and about pain.
• You will have an MRI of the spine (except for Month 1).

If you are unable to return for follow-up clinic visits, you will be called and asked about your medical history, and you will complete the 3 questionnaires about your health, symptoms you may be having, and about pain. This call should take about 20 minutes.

Length of Study:

Your treatment will last 1 day. You will continue having follow-up visits or phone calls for as long as possible.

This is an investigational study. SSRS is FDA approved. The use of SSRS to treat metastatic epidural spinal cord compression is investigational.

Up to 36 patients will take part in this study. All will be enrolled at M. D. Anderson.

Eligibility Criteria

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

Exclusion Criteria

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

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

• Minimum Eligible Age: 18 Years
