Eligibility Criteria
You may qualify if:
- Men and women age 18 and older
- Patients who are able and willing to give consent and able to attend all study visits
- Patients who are suffering from symptoms of bone metastases
- One to 3 painful lesions.
- Targeted tumor(s) 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)
- Patients with persistent distinguishable pain associated with up to 3 tumors of which a maximum of 2 tumors will be treated:
- o If patient has pain from additional sites that are not planned for treatment, the pain from the additional sites must be evaluated as being less intense by at least 2 points on the NRS compared to the site(s) to be treated.
- Patient with NRS (0-10 scale) pain score ≥ 4 at the targeted tumors (i.e: both tumors targeted for treatment must have NRS ≥ 4) irrespective of medication
- Targeted tumors (most painful) size up to 8 cm in diameter
- Patient whose targeted (most painful) tumors are on bone and bone-lesion interface is deeper than 1cm from the skin.
- Targeted (most painful) tumors clearly visible by non-contrast MRI, and ExAblate MRgFUS device accessible
- Able to communicate sensations during the ExAblate MRgFUS treatment
- At least 2 weeks since chemotherapy
- No radiation therapy to targeted (most painful) tumors in the past two weeks
You may not qualify if:
- Patients who either
- Need surgical stabilization of the affected weight bearing bony structure (\>7 fracture risk score, see Section 6.9) OR
- Targeted tumor is at an impending fracture site of the weigh bearing bone (\>7 on fracture risk score, see Section 6.9).
- o Patients with surgical stabilization of tumor site with metallic hardware
- More than 3 painful lesions or more than 2 requiring immediate localized treatment
- The targeted tumor(s) is (are) less than 2 points more painful compared to other non-targeted painful lesions on the site specific NRS.
- Targeted tumor is in the skull
- Patients on dialysis
- Patients with life expectancy \< 6-Months
- Patients with an acute medical condition (e.g., pneumonia, sepsis) that is expected to hinder them from completing this study.
- Patients with unstable cardiac status including:
- Unstable angina pectoris on medication
- Patients with documented myocardial infarction within six months of protocol entry
- Congestive heart failure requiring medication (other than diuretic)
- Patients on anti-arrhythmic drugs
- +16 more criteria
