[Radiotherapy for metastatic bone tumor].

There is good evidence that radiotherapy is effective in relieving bone pain due to metastatic tumor. For localized bone pain, external beam treatment will be successful in reducing pain in some 80% of patients. Many prospected randomized trials show single fractions as effective as more prolonged regimens both in terms of incidence and duration of pain relief. For scattered painful metastases, wide-field hemibody irradiation or the systemic administration of radioisotopes is effective.
