What side effects are associated with this type of intervention?

Common treatments for breast cancer, including partial tumor ablation techniques like the Muse MRgFUS System, can have various side effects. For partial tumor ablation, side effects may include localized pain, swelling, and potential skin burns. Chemotherapy often leads to side effects such as alopecia (hair loss), fatigue, nausea, and increased risk of infections. Radiotherapy can cause skin irritation, fatigue, and in some cases, lymphedema. Hormone therapy may result in hot flashes, mood swings, and an increased risk of blood clots. It is important to discuss these potential side effects with a healthcare provider to manage and mitigate them effectively.

What prior FDA approvals exist?

The FDA has approved various treatments for breast cancer, including surgical options, chemotherapy, radiation therapy, hormone therapy, and targeted therapy. While the Muse MRgFUS System focuses on partial tumor ablation using magnetic resonance-guided focused ultrasound, similar FDA-approved treatments include radiofrequency ablation (RFA) and cryoablation. These minimally invasive techniques aim to destroy cancer cells by applying extreme heat or cold, respectively. Additionally, the FDA has approved several targeted therapies, such as trastuzumab and pertuzumab, which specifically target cancer cells with minimal damage to surrounding tissues.

What other types of research exist?

Promising novel alternatives to the Muse MRgFUS System for breast cancer treatment in 2024 include: 1) Tucatinib-capecitabine-trastuzumab regimen, particularly for HER2-positive patients with brain metastases, due to its significant overall survival benefit. 2) Fam-trastuzumab deruxtecan (T-DXd), especially for patients with stable/treated brain metastases and significant extracranial progression. 3) Trastuzumab-emtansine (T-DM1), depending on prior therapy exposure. These systemic therapies have demonstrated efficacy in both treated and untreated brain metastases and may offer comprehensive treatment options for breast cancer patients.

BreastMRgFUS Trial Summary

This trial is testing a new system that uses MR-guided focused ultrasound to partially ablate breast tumors in order to make them easier to remove surgically. The system is being studied for safety, tolerability, and effectiveness.

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.Check my eligibility

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.See study design

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.

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.
