title: Skeletal metastases.
abstract: This synthesis of the literature on radiotherapy for skeletal metastases is based on 171 scientific articles, including 13 randomized studies, 24 prospective studies, and 79 retrospective studies. These studies involve 13054 patients. Radiotherapy has been well documented as a method for alleviating pain, but the mechanisms underlying this effect are largely unknown. When used for pain palliation, radiotherapy achieves freedom from pain, or substantial alleviation of pain in nearly all cases, with few side effects. Half-body irradiation is effective in treating multiple metastatic sites and should be considered for use more frequently. However, this increases the requirements on equipment, dosimetry, and hospital beds. Systemic radiotherapy with radionuclides may be indicated for generalized skeletal pain. The role of radiotherapy in preventing or healing fractures is not fully evaluated. Optimum dose levels and fractionation schedules have not been established. Early radiotherapy for spinal cord compression may prevent symptoms from worsening, but the effects on existing paralysis are modest.
