Basic Information

• Recruitment Status: COMPLETED

Brief Summary

RATIONALE: Stereotactic body radiation therapy may be able to send x-rays directly to the tumor and cause less damage to normal tissue. Vertebroplasty may help prevent fractures and spinal cord compression caused by spinal metastasis. Giving stereotactic body radiation therapy together with vertebroplasty may help lessen pain and improve quality of life of patients with spinal metastasis.

PURPOSE: This phase II trial is studying how well giving stereotactic body radiation therapy together with vertebroplasty works in treating patients with localized spinal metastasis.

Detailed Description

OBJECTIVES:

Primary

• To determine the efficacy of stereotactic body radiotherapy in reducing pain at 3 months in patients with localized spinal metastasis.

Secondary

• To determine the duration of pain response at the treated site(s) scored as the time of maximal pain relief to an increase of 2 points on the Visual Analogue Scoring System.
• To determine the functional preservation of improvement as measured by the Brief Pain Inventory.
• To prospectively assess quality of life using the FACT-G and EQ-5D questionnaires.
• To determine the long-term stability of the treated vertebral bone (e.g., fracture, sclerotic change, vertebral body height, or malalignment) as measured by MRI, CT scan, and plain radiographs.

OUTLINE: Patients are assigned to 1 of 2 treatment groups according to prior radiotherapy to the planned treatment site(s).

• Group 1 (prior radiotherapy): Patients undergo 5 fractions of stereotactic body radiotherapy (SBRT) over 30-90 minutes each.
• Group 2 (no prior radiotherapy): Patients undergo 1 fraction of SBRT over 30-90 minutes.

Within 1 month after the initiation of SBRT, patients in both groups undergo percutaneous vertebroplasty.

Patients complete pain and quality-of-life questionnaires at baseline and periodically during study. Patients also undergo MRI and CT scan at baseline, at 1, 3, and 6 months, and then every 6 months for 3 years to assess changes in vertebral bone strength and stability.

After completion of study therapy, patients are followed at 2 weeks, at 1, 3, and 6 months, and then every 6 months for 3 years.

Study Groups

Radiation followed by Vertebroplasty

Intervention:

This study is one arm. All patients will undergo radiotherapy followed by vertebroplasty. Patients who had prior radiotherapy will undergo 5 fractions of stereotactic body radiotherapy (SBRT) over 30-90 minutes each. Patients has no prior radiotherapy will undergo 1 fraction of SBRT over 30-90 minutes. The full patient population will then undergo vertebroplasty*.

*Vertebroplasty may not be possible for certain patients due to tumor location or safety. In such cases, patients will omit the vertebroplasty but receive all other protocol care and follow-up.

• For women of childbearing age a negative pregnancy test is required
• Patients considered for the retreatment arm, must not of had prior radiation to the proposed spinal site within a 3 month interval prior to treatment
• Zubrod score of 0-2

Exclusion:

• Patients who have been non-ambulatory for more than 7 days
• Patients with compression fractures
• Spine instability requiring fixation
• Patients with paraspinal extension
• Patients with bony fragments
