Magnetic marker localisation in breast cancer surgery

Area of Science:

• Oncology
• Surgical Technology
• Medical Imaging

Background:

• Mammographic screening has led to earlier detection of impalpable breast cancers.
• This shift necessitates advanced localization techniques for non-palpable tumors.
• Magnetic markers have emerged as a novel approach for tumor and lymph node localization.

Purpose of the Study:

• To provide an updated review of magnetic marker systems in breast cancer surgery.
• To focus on the Magseed and MaMaLoc systems for localizing breast tumors and axillary nodes.
• To evaluate the safety, reliability, and clinical outcomes of magnetic marker localization.

Main Methods:

• Review of current literature and prospective studies on magnetic marker systems.
• Focus on Magseed and MaMaLoc technologies.
• Comparison of magnetic marker outcomes with traditional localization methods.

Main Results:

• Magnetic marker localization is a safe and reliable method for breast tumor marking.
• Prospective studies show Magseed achieves negative margin and successful localization rates comparable to standard systems.
• Key benefits include no radiation safety requirements and extended deployment times for scheduling flexibility.

Conclusions:

• Magnetic markers represent a viable alternative for breast tumor and lymph node localization.
• Advantages include improved surgical scheduling and elimination of radiation concerns.
• System cost, depth limitations, and probe recalibration frequency are notable drawbacks.
