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

Summary

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

Detailed description

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

Arms & interventions

• BiologicalEXTERNAL BEAM RADIATION

  A minimum of three daily radiation therapy treatments are required in any given week. Any missed radiation treatments will be made up at the end of the treatment schedule, such that the total number of delivered 5 Gy fractions remains ten.
