Palliative radiotherapy in the treatment of skeletal metastases
Abstract
Two-third of patients with metastatic cancer suffer from pain. Pain originating from skeletal metastases is the most common form of cancer pain. Bone pain, often exacerbated by pressure or movement, limits the patient's autonomy and social life. Pathological fracture and spinal cord compression are additional complications caused by bone metastases. Radiotherapy is effective in treating bone pain not adequately controlled by analgesics. Seventy percent of patients benefit from radiotherapy. Single and multifraction regimens are equally effective in relieving pain. Retreatment is needed somewhat more often following single fraction therapy. Most patients benefit from retreatment irrespectively of previous fractionation schedule. Hemibody irradiation and radioisotopes, e.g., strontium-89 and samarium-153 are used in treating scattered painful bone metastases. Radiotherapy is used for preventing pathological fracture by treating osteolytic lesions especially in the weight-bearing bones such as the spinal column and long bones. Radiotherapy is the treatment of choice in spinal cord compression, which is the most serious complication caused by bone secondaries. Radiotherapy provides efficient, well-tolerated and cost-effective palliative care.
