About

The primary purpose of this protocol is to assess the ExAblate 2100 MR guided high intensity focused ultrasound device as an intervention for treatment of advanced stage pancreatic adenocarcinoma.

Full description

Primary Objective: The primary endpoints for this study will be 1) feasibility of ablation and 2) safety of ablation.

Secondary Objective: 1.)Pain reduction after ablation. 2.) Evidence of inflammation at ablation site based on histology, or in blood after ablation

Enrollment: 1 patient

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Men and women ≥ 18 years of age
• Patients willing to sign a written informed consent document
• Patients with unresectable, locally advanced or metastatic pancreatic adenocarcinoma
• Patients with upper abdominal pain rating at least 4 out of 10 in severity on BPI
• Tumor must be visualized on CT or MRI, obtained within 30 days of enrollment
• Tumor must be accessible to the ExAblate MRgFUS device

Exclusion criteria

• Previous pancreatic surgery

• Patients with contraindication for MR imaging such as implanted metallic devices that are not MRI-safe, size limitations, claustrophobia, etc.

• Patients with known intolerance or allergy to MR contrast agent (gadolinium chelates) including advanced kidney disease (GFR <30 mL/min/1.73 m2) or on dialysis

• Pregnant and nursing patients will be excluded from the study because of a contraindication to administering MRI contrast agents to these patients

• Target is:

  1. NOT visible by non-contrast MRI, OR
  2. NOT accessible to ExAblate device

• Individuals who are not able or willing to tolerate the required prolonged stationary position during treatment (can be up to 6 hrs of total table time)

• Patients with acute medical condition (e.g. pneumonia, sepsis) that is expected to hinder them from completing this study

• Patients with unstable cardiac status including:

  1. Unstable angina pectoris on medication
  2. Patients with documented myocardial infarction within six months of protocol entry
  3. Congestive heart failure requiring medication (other than diuretic)
  4. Patients on anti-arrhythmic drugs
  5. Patients with severe hypertension (diastolic BP > 100 on medication)
  6. Patients with severe hematologic, neurologic, or other uncontrolled disease (e.g. platelets < 50,000/microL, INR > 1.5)

• Patients who are taking anti-thrombotic medication
