Possible Dose-Response Relationship in Palliative Radiotherapy for Non-bone Painful Lesions

摘要

Aims: Total radiation dose does not predict pain response in conventionally fractionated radiotherapy for bone metastases. By contrast, in radiotherapy for solid painful tumours other than bone metastases, it is unknown whether there is a dose-response relationship. We sought to determine whether a higher total radiation dose predicted a higher pain response rate in palliative radiotherapy for non-bone painful lesions.
