Palliative Dose Escalated Radiation for Painful Non-Spine Bone Metastases and Painful Non-Bone Metas

Overview

The investigators hypothesize that with dose escalation to 40-50 Gy in ten fractions, the complete pain response rate at one month can be increased to 40-50% in painful non-spinal bone metastases. Additionally, the investigators hypothesize that utilizing a fractionation scheme with an escalated biologically equivalent dose (BED) will result in a higher proportion of participants responding to treatment, and will also lead to more durable responses. Furthermore, the investigators hypothesize that with dose escalation to 40-50 Gy in ten fractions, the complete pain response rate at one month can be increased to 35-45% in painful non-bone metastases

The purpose of this study is to prospectively evaluate dose escalation and pain response in patients with painful non-spinal bone metastases and painful non-bone metastases treated with radiation therapy. Primary Objective: To evaluate improvement of complete pain response rate in painful non-spine bone metastases and painful non-bone metastases with dose escalated radiation using a ten fraction radiation regimen Secondary Objectives: To evaluate best pain response To evaluate mean pain scores To evaluate the duration of pain response To evaluate the changes in quality-of-life following radiation To evaluate the rates of retreatment with radiation secondary to disease or symptom progression To evaluate treatment related toxicity
