Focused Ultrasound Therapy
Focused 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 cervical tumors. This novel technology focuses beams of ultrasound energy precisely and accurately on targets deep in the body without damaging surrounding normal tissue.
How it Works
Where the beams converge, focused ultrasound produces precise ablation (thermal destruction of tissue) enabling cervical tumors to be treated without surgery. While significant work has been accomplished, there is still much to be done before this technology will be widely available.
The primary options for treatment of cervical tumors include medication and invasive surgery.
For certain patients, focused ultrasound could provide a noninvasive alternative to surgery with less risk of complications – such as surgical wound healing or infection – at a lower cost. Focused ultrasound can reach the desired target without damaging surrounding tissue, and enhance chemotherapy dose for the target, with less impact to the rest of the patient. It can also be repeated, if necessary.
A clinical trial is recruiting patients with solid tumors with metastatic lesions, including cervical cancer, at the University of Virginia.
A clinical trial is underway in London, United Kingdom that is using focused ultrasound to treat pelvic cancer of many causes, including cervical cancer.
Regulatory Approval and Reimbursement
Focused ultrasound treatment for cervical tumors is not yet approved by regulatory bodies or covered by medical insurance companies.
