Summary

This trial is testing the Muse MRgFUS System, which uses sound waves guided by MRI to partially destroy breast tumors. It targets breast cancer patients with multiple tumor sites. The sound waves heat and kill part of the tumor while MRI ensures precise targeting. This noninvasive technique has been shown to treat both benign and malignant tumors.

Who is the study for?
This trial is for women under 50 with unilateral, unifocal invasive breast cancer planning a lumpectomy. They must be able to lie prone for 90 minutes, have no severe allergies to gadolinium contrast or sedatives, and not have had prior radiation in the affected breast or certain other cancers within the last two years. Participants should not be pregnant and must use effective contraception if of childbearing potential.
What is being tested?
The study tests the Muse MRgFUS System's safety and effectiveness in partially ablating breast tumors before surgical removal. Patients will undergo ablation of half their tumor followed by standard surgery. The trial aims to ensure that partial ablation does not delay or affect subsequent care while evaluating treatment outcomes through imaging and tissue analysis.
What are the potential side effects?
While specific side effects are not listed, they may include discomfort from lying prone during treatment, reactions to MRI contrast agents like gadolinium (if allergic), or issues related to sedation required for the procedure.

Experimental Treatment
Group I: Muse MRgFUS SystemExperimental Treatment1 Intervention
Subjects will undergo partial ablation of half (≤50%) of one of their tumors (if multifocal or multicentric disease) followed by surgical resection per standard of care.

Other Research
The Muse MRgFUS System uses focused ultrasound waves guided by magnetic resonance imaging to ablate part of the tumor tissue, offering a non-invasive approach to reduce tumor size while preserving healthy tissue. Other common treatments include surgery to remove the tumor, radiation therapy to kill cancer cells with high-energy rays, chemotherapy to target rapidly dividing cells, and hormone therapy to block hormones that fuel certain breast cancers. These treatments are essential for managing and potentially eradicating breast cancer, providing tailored strategies based on the tumor's characteristics and the patient's condition.
