Overview

Brief Summary

The purpose of this study is to investigate the safety and effectiveness of subjects receiving MR-guided Focused Ultrasound (MRgFUS) treatment for painful bone metastases. This study will evaluate treatment response and clinically significant adverse events. Other relevant data may be documented as well.

Detailed Description

This proposed study will be performed in full compliance with all applicable privacy rules and regulations, and their implementations at participating site(s). All subjects planned to undergo the MRgFUS procedure at Taipei Medical University Hospital will be offered informed consent so they can be included in this Study.

•Patients who are suffering from symptoms of bone metastases: Patients who have received radiation without adequate relief from metastatic bone pain as determined by the patient and treating physician, those for whom their treating physician would not prescribe radiation or additional radiation treatments, and those patients who refuse additional radiation therapy.
•Patient with NRS (0-10 scale) pain score ≥ 4 irrespective of medication.
•Targeted bone/tumor interface are ExAblate device accessible and are located in ribs, extremities (excluding joints), pelvis, shoulders and in the posterior aspects of the following spinal vertebra: Lumbar vertebra (L3-L5), Sacral vertebra (S1-S5).
•Patient whose targeted lesion is on bone and the interface between the bone and lesion is deeper than 10-mm from the skin.
•Targeted (treated) tumor clearly visible by non-contrast MRI, and ExAblate MRgFUS device accessible.
•Patients on ongoing chemotherapy regimen at the time of eligibility: 1) with same chemotherapy regimen (as documented from patient medical dossier, 2) worst pain NRS still ≥ 4, and 3) do NOT plan to initiate a new chemotherapy for pain palliation should be eligible for the study. Note: Planned multiple courses of chemotherapy are not considered New Chemotherapy.
•No radiation therapy to targeted (most painful) lesion in the past two weeks.

•Target (treated) tumor is less then 10-mm from nerve bundles, bowels or bladder.
•Patients with acute medical condition (e.g., pneumonia, sepsis) that is expected to hinder them from completing this study.
•Severe cerebrovascular disease (multiple CVA or CVA within 6 months).
