RATIONALE: Stereotactic radiosurgery can send x-rays directly to the tumor and cause less damage to normal tissue. It may also help patients with spinal metastases live more comfortably.

PURPOSE: This phase I trial is studying the side effects and best dose of stereotactic radiosurgery in treating patients with spinal metastases.

Condition Intervention Phase
Metastatic Cancer
Other: questionnaire administration
Procedure: diffusion tensor imaging
Procedure: functional magnetic resonance imaging
Radiation: hypofractionated radiation therapy
Radiation: stereotactic radiosurgery

Primary Outcome Measures:
  • Maximum tolerated dose of CyberKnife® hypofractionated stereotactic radiosurgery [ Time Frame: 6 weeks ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:

  • Spinal cord response as measured by functional MRI [ Time Frame: baseline and then at 6 weeks and 6 months after completion of treatment ] [ Designated as safety issue: No ]

Estimated Enrollment: 36
Study Start Date: January 2009
Estimated Study Completion Date: June 2016
Primary Completion Date: June 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Stereotactic radiosurgery
Radiation: stereotactic radiotherapy Questionnaire administration diffusion tensor imaging functional magnetic resonance imaging hypofractionated radiation therapy
Other: questionnaire administration
prior to radiosurgery, at radiosurgery completion, and then at subsequent follow-ups (3, 6, 9, 12, 18, and 24 months after treatment
Procedure: diffusion tensor imaging
prior to initiating CyberKnife radiosurgery, at 6 weeks after CyberKnife therapy, and at 6 months after CyberKnife therapy
Procedure: functional magnetic resonance imaging
prior to CyberKnife, at 6 weeks, and 3 months after CyberKnife?, every 3 months for the first year, and every 6 months thereafter
Radiation: hypofractionated radiation therapy
two to three consecutive daily sessions within one week
Radiation: stereotactic radiosurgery
two to three consecutive daily sessions within one week

Detailed Description:


  • To implement CyberKnife® technology for improving palliation in patients with spinal metastases.
  • To determine the maximum tolerated dose of CyberKnife® hypofractionated stereotactic radiosurgery in these patients.
  • To evaluate functional and diffusion MRI parameters in the spinal cord and tumor after treatment with Cyberknife® radiosurgery.

OUTLINE: Patients undergo placement of gold fiducial markers at the time of open surgical resection or percutaneous needle biopsy. Patients then undergo CyberKnife® hypofractionated stereotactic radiosurgery over 30-90 minutes daily for 2-3 days.

Patients undergo functional MRI and diffusion tensor imaging at baseline and then at 6 weeks and 6 months after completion of treatment. Patients also complete a pain questionnaire at baseline and then at 3, 6, 9, 12, 18, and 24 months after completion of treatment.

After completion of study treatment, patients are followed periodically for up to 2 years.


Ages Eligible for Study:   18 Years and older

      • Solitary spinal metastasis
      • Two contiguous spinal levels

        • No more than 2 adjacent spinal levels involved by a single tumor
      • Involvement of ≤ 3 separate sites (e.g., C5, T5, and T12)
    • Tumor size ≤ 5 cm
