Radiofrequency Ablation in Treating Patients With Bone Metastases
A Phase I/II Study of Percutaneous Radiofrequency Ablation of Bone Metastases Using CT Guidance

RATIONALE: Radiofrequency ablation may be effective in decreasing pain from bone metastases.

PURPOSE: Phase I/II trial to study the effectiveness of radiofrequency ablation in decreasing pain in patients who have bone metastases.


  • Determine the side effects of radiofrequency ablation in patients with bone metastases.
  • Determine the effect of this regimen on pain in these patients.
  • Determine the effect of this regimen on mood in these patients.
  • Determine the effects of narcotic usage in patients treated with this regimen.
  • Determine the relationship between laboratory and imaging features of this treatment and the effects of the treatment in these patients.

OUTLINE: This is a multicenter study.

Patients undergo percutaneous CT-guided radiofrequency ablation directly to the metastatic lesion over approximately 12 minutes.

Pain and mood are assessed at baseline, daily for 14 days after treatment, and at 1 and 3 months after treatment.

Patients are followed at 1 week and then at 1 and 3 months.

PROJECTED ACCRUAL: Approximately 75 patients will be accrued for this study within 12.5 months.
