title: Bone metastases: approaches to management.
abstract: Cancer commonly metastasizes to bone and up to 80% of breast, prostate, and lung cancer patients will have bone metastases. The site and distribution of bone metastases, and the presence of skeletal complications such as pathologic fracture and spinal cord compression affect the patient's prognosis. In many cases, bone metastases are too advanced to be eliminated through chemotherapy or radiotherapy; in these cases, treatment is given to relieve or prevent further symptoms. Several treatments are used in palliative care, including radiation therapy, systemic radiopharmaceuticals, chemotherapy, hormone therapy, and bisphosphonates. Radiotherapy remains the treatment of choice, and radiation treatment given in a single fraction has proven to be an efficient and cost-effective alternative to traditional multifraction radiotherapy courses. Analgesics are important in palliative therapy because they relieve pain while administering and awaiting the relief of pain from treatment. Furthermore, analgesics will relieve persistent levels of pain if complete pain relief is not achieved with therapy. Currently, bone pain is not adequately treated by many physicians and up to 79% of patients experience severe pain in the period before palliative therapy.
