A novel optical wire enhances breast-conserving surgery by creating a visible light glowball around small lesions, improving surgical guidance and accuracy for nonpalpable tumors.

Area of Science:

  • Medical Devices
  • Surgical Technology
  • Biomedical Optics

Background:

  • Traditional wire localization is standard for nonpalpable breast lesions.
  • Accurate localization is crucial for effective breast-conserving surgery.
  • Enhancements to current localization methods are needed to improve outcomes.

Observation:

  • A 200-μm optical fiber was integrated with a standard localization wire.
  • The modified optical wire fits through an 18-gauge needle for breast insertion.
  • Radiologists use ultrasound and mammography to anchor the wire at the lesion.

Findings:

  • Illumination of the optical wire tip creates a visible 'glowball' of light around the lesion.
  • Surgeons can easily visualize this glowball in the operating room.

  • The glowball provides clear guidance for lesion identification and resection.

    • Implications:

    • Light-guided lumpectomy offers a simple enhancement to wire localization.
    • This technique can improve the standard of care for small, nonpalpable breast lesions.
    • Enhanced visualization may lead to more precise surgical removal and better patient outcomes.
