Focused Ultrasound Therapy

Clinical Trials SquareFocused ultrasound is an early-stage, noninvasive, therapeutic technology with the potential to improve the quality of life and decrease the cost of care for patients with tumors of the head and neck. This novel technology focuses beams of ultrasound energy precisely and accurately on targets deep in the body without damaging surrounding normal tissue. Where the beams converge, the ultrasound produces precise ablation (thermal destruction of tissue) enabling tumors to be treated without surgery. (Although tumors of the thyroid is located in the neck, please see the section on thyroid tumors for information on this application.)

The primary option for treatment of tumors of the head and neck is invasive surgery, although radiation, chemotherapy or other pharmaceuticals may also be used.

For certain patients, focused ultrasound could provide a noninvasive alternative to surgery with less risk of complications and lower cost.

Advantages:

  • Focused ultrasound is noninvasive, so it does not carry added concerns like surgical wound healing or infection.
  • Focused ultrasound can reach the desired target without damaging surrounding tissue.
  • Enhanced chemotherapy dose for the target, with less impact to the rest of the patient.
  • It can be repeated, if necessary.

Clinical Trials

A clinical trial is recruiting patients with solid tumors with metastatic lesions, including esophagael cancer, at the University of Virginia.

A clinical trial for patients who have cancer with metastases to the lymph nodes in the head and neck is underway at the Sunnybrook Health Sciences Centre, in Toronto, Canada. This study is only open to Canadian residents. 

clinical trial is recruiting patients who have severe, opioid-resistant pain from head and neck cancer at the University of Virginia.

Regulatory Approval and Reimbursement

Focused ultrasound treatment for head and neck tumors is not yet approved by regulatory bodies or covered by medical insurance companies.
