Unanswered Questions About SBRT in Bone Metastases
June 02, 2008
The goal of palliative radiotherapy is to treat symptoms as rapidly and efficiently as possible, with the fewest side effects. For many years, pain medication, radiotherapy, and surgery were the only tools available for the treatment of bone metastases. This has changed significantly over the past 15 years. New systemic agents, including bisphosphonates such as zoledronic acid (Reclast, Zometa), are available to prevent the development of new lesions, strengthen the bone, and improve symptoms. In addition, targeted treatments directed at achieving tumor ablation now include radiofrequency ablation and stereotactic body radiation therapy (SBRT).
