A Trial to Improve Quality of Life With Stereotactic Body Radiotherapy for Patients With Painful Bone Metastases

Treatment will be prescribed to the periphery of the target, i.e. 80% of the dose should cover 95% of the PTV. The organ at risk (OAR) dose constraints will be in accordance with the recommendations from the report of the American Association of Physicists in Medicine (AAPM) task group 101. Image-guidance will consist of cone-beam CT in combination with 6 degrees of freedom corrections using robotic couch.

In the standard setting, 95% of the PTV should receive 95% of the prescribed dose while near maximum dose (Dnear-max) in the PTV should not exceed 107%. Image-guidance will consist of portal images showing the relevant bony anatomy.
