Study Description

Brief Summary: This purpose of this study is to assess the feasibility of FLASH radiotherapy for the palliative treatment of painful bone metastases. FLASH radiotherapy is radiation treatment delivered at ultra-high dose rates compared to conventional radiation treatment.

Detailed Description: This clinical investigation is designed to assess the workflow feasibility of FLASH radiotherapy treatment in a clinical setting, as well as the toxicities, and pain relief when used to treat bone metastasis(-es) in the extremities (excluding feet, hands, wrists). FLASH radiotherapy has been shown in preclinical studies to cause less injury to surrounding normal tissues during radiation treatment, while still having similar tumor cell killing. Patients at least 18 years of age with painful bone metastases located in the limbs will be considered for the study. These patients represent an ideal population for a feasibility study of FLASH radiotherapy as they are known to benefit from the palliative effects of radiotherapy using single dose radiation regimens of 8Gy which is what is being used in this investigation. After treatment, patients will be assessed for pain response as well as any adverse side-effects of radiation. The workflow feasibility of the treatment will also be evaluated.
