[Bone metastasis: Efficacy and technical modalities of classical radiotherapy].

Conventional radiotherapy is a pivotal treatment in the management of bone metastasis. It is indicated primarily for palliative, analgesic, or decompressive purposes and in the prevention of severe bone events such as fractures and spinal cord compressions. It should be performed as early as possible from the onset of symptoms or within 14days following a surgical procedure of decompression or bone stabilization. Except in some cases, a pattern of 8Gy single dose is currently recommended, possibly renewable, by being vigilant on associated treatments which some, like antiangiogenics, must be imperatively suspended.
