Brief summary
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.
