Awards & highlights


This trial looks at how focused ultrasound (FUS) affects tumor microenvironments. Researchers will compare areas with and without FUS to measure changes in the brain & tumor molecules. It could lead to new ways to study cancer drugs & therapies.

Who is the study for?
This trial is for adults with a suspected or diagnosed diffuse glioma brain tumor, large enough (≥3cm) to be partially targeted by focused ultrasound but small enough for standard surgery. Participants must be able to undergo surgery in Rochester, MN and have an ECOG performance status of 0-2. Pregnant women, prisoners, those mentally handicapped, or anyone with certain cardiac diseases or blood-borne infections are excluded.Check my eligibility
What is being tested?
The study tests the effect of focused ultrasound on brain tumors using InSightec's ExAblate Neuro Model system. It aims to understand how this technique alters the tumor microenvironment by comparing regions treated with FUS against untreated ones through microdialysis catheters.See study design
What are the potential side effects?
Potential side effects may include risks associated with general surgical procedures such as infection and bleeding. Specific side effects related to the use of focused ultrasound and disruption of the blood-brain barrier are not detailed but could involve neurological changes.

Other Research
Common treatments for brain tumors include chemotherapy, which uses drugs to kill cancer cells or stop them from growing; radiotherapy, which uses high-energy radiation to destroy cancer cells; and surgery, which physically removes the tumor. Focused Ultrasound (FUS) is a novel treatment being studied for its ability to disrupt the blood-brain barrier, allowing for better drug delivery directly to the tumor site. This is significant for brain tumor patients as it can potentially enhance the effectiveness of chemotherapy and other treatments by improving drug penetration and altering the tumor microenvironment, leading to better treatment outcomes.
