MRgFUS Versus EBRT in Patients With Metastatic Non-spinal Bone Disease
Secondary Bone Cancer, Bone Metastases
About this trial
This is an interventional treatment trial for Secondary Bone Cancer focused on measuring Bone Metastases
Eligibility Criteria
Inclusion Criteria:
- Men and women age 18 years and older.
- Able and willing to give consent and to attend all study visits
- Patients with bone metastasis or primary bone lesion identifiable by imaging techniques.
- Worst NRS Pain Score of ≥ 4 from the tumor to be treated.
- Each targeted tumor is accessible to both ExAblate and EBRT (ExAblate accessible lesions 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), please see ExAblate "Information for Prescribers".
- Targeted tumor area is smaller than 100cm2.
- Tumor clearly visible by non-contrast MRI.
- No radiation therapy to selected lesion during one month prior to enrollment.
- Radiation therapy to selected lesion is not contraindicated
- Bisphosphonate, chemo or hormone therapy intake should remain stable throughout follow up duration.
Exclusion Criteria:
- Patients who either need pre-treatment surgical stabilization of the affected bony structure
- Targeted tumor is in a vertebra body or in the posterior aspects of the vertebral column other than Lumbar vertebra (L3 - L5) and Sacral vertebra (S1 - S5).
- Targeted tumor is in the skull.
- Patients on anti-coagulation therapy or with an underlying uncontrolled bleeding disorder.
- Patients with life expectancy < 6-Months.
Patients with unstable cardiac status including:
- Unstable angina pectoris on medication.
- Patients with documented myocardial infarction within last 40 days to protocol entry.
- Congestive heart failure NYHA Class IV
- Severe hypertension (diastolic BP > 100 on medication).
- Patients with standard contraindications for MR imaging such as non-MRI compatible implanted ferromagnetic objects/devices.
- Known intolerance or allergies to MRI contrast agent (e.g. Gadolinium or Magnevist)
- KPS score of below 60
- Severe cerebro-vascular disease (multiple CVA or CVA within 6 months)
- Individuals who are not able or willing to tolerate the required prolonged stationary position during treatment (approximately 2 hrs.)
- Target tumor is less then 1cm from spinal cord, skin, or hollow viscera.

MRgFUS

The treatment process begins with the physician acquiring a set of MR images, identifying target volume(s) of tissue to ablate, and then drawing the treatment contours. The therapy planning software computes the type and number of sonications required to treat the defined region while minimizing total treatment time. MR images taken during the sonication provide a diagnostic quality image of the target tissue and a quantitative, real-time temperature map overlay to confirm the therapeutic effect of the treatment
Patient would undergo single fraction of external beam radiation to a dose of 8Gy or a session of 10 fractions of external beam radiations at 3Gy per fraction for two weeks.
