Ovarian Tumors

Focused Ultrasound Therapy

Focused ultrasound is a rapidly evolving, noninvasive, therapeutic technology with the potential to improve the quality of life and decrease the cost of care for patients with ovarian 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). This destruction can be done to completely destroy the target or to partially treat it, and partial treatment is believed to stimulate the patient’s immune response, which may have a broader impact.

The primary options for treatment of ovarian cancer 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. It can reach the desired target without damaging surrounding tissue and is repeatable, if necessary. Focused ultrasound also offers enhanced chemotherapy dose for the target, with less impact to the rest of the patient.

Clinical Trials

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

Regulatory Approval and Reimbursement

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