Overview

Bone metastases are a cause of significant morbidity in cancer patients. In patients who die from breast, prostate, and lung cancer, autopsy studies have shown that up to 85% have evidence of bone metastases at the time of death (1). These metastases frequently give rise to complications that reduce patients' quality of life. These include: pain, fractures, and decreased mobility, ultimately reducing performance status. Radiofrequency ablation therapy with cementoplasty/vertebroplasty for painful bone metastases has been shown to be feasible, efficacious, and safe. However, patient reported outcomes have yet to be determined.

Outcomes

Primary Outcomes

Pain response

To determine the complete and partial pain response rates in patients who undergo radiofrequency ablation (RFA) and/or cementoplasty/vertebroplasty for spinal/pelvic metastases.

Time frame: Baseline to 6 weeks post treatment

Secondary Outcomes

Functional Interference

To investigate how functional interference of pain changes

Time frame: Baseline - 6 weeks post treatment

Quality of Life

To investigate quality of life changes

Time frame: Baseline - 6 weeks post treatment

Side-effects

To investigate acute side effects of treatment

Time frame: Baseline-6 weeks post treatment
