Palliative Radiotherapy (including SBRT)

External beam radiation therapy (SBRT if applicable) may be considered when bone metastases cause persistent pain, there is a risk of pathological fracture or spinal cord/nerve compression, or local control is needed after surgery/ablation. The decision is influenced by the primary tumor type, lesion location and number, prior radiation history, systemic treatment plan, and organ tolerance, and is determined by a comprehensive specialist assessment.
