Colorectal Tumors

Focused Ultrasound Therapy

Clinical Trials Square

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 colorectal cancer. 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 colorectal cancer to be treated without surgery. While significant preclinical work has been performed, there is still much to be done before this technology will be widely available.

The primary options for treatment of colorectal cancer include medication or invasive surgery.

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 in Canada is using focused ultrasound induced hyperthermia to treat recurrent rectal cancer. This trial is only open to Canadian Citizens.

A clinical trial is underway in London, England is assessing endoluminal focused ultrasound to treat patients with pelvic cancer (including colorectal cancer and other pelvic cancers) when all other treatment modalities have been exhausted.

Regulatory Approval and Reimbursement

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