Bracketing wires in breast cancer surgery help surgeons remove calcifications but do not guarantee clear margins for malignancy. This technique is mainly for larger, suspicious lesions.

Area of Science:

  • Radiology
  • Oncology
  • Surgical Oncology

Background:

  • Preoperative needle localization is crucial for guiding breast lesion excision.
  • Bracketing wires, defined as multiple wires delineating a single lesion, are a specific technique within needle localization.
  • Understanding the efficacy of bracketing wires is important for optimizing surgical outcomes.

Purpose of the Study:

  • To evaluate the outcomes of using bracketing wires during preoperative needle localization for breast lesions.
  • To assess the impact of bracketing wires on lesion excision and margin status.

Main Methods:

  • A prospective study examined 1057 lesions undergoing needle localization and surgical excision.
  • Mammograms were classified using Breast Imaging Reporting and Data System (BI-RADS) categories.

  • Bracketing wires were used in 103 lesions; these cases were reviewed for lesion characteristics, surgical findings, and margin status.

    • Main Results:

    • Bracketing wires were primarily used for larger lesions (median 3.5 cm), often calcific (90.3%) and BI-RADS category 5 (63.1%).
    • Of the 75 cancers identified, bracketing wires achieved clear histologic margins in 44.0%.
    • Complete removal of calcifications was achieved in 81.0% of calcific lesions with available postoperative mammograms.

    Conclusions:

    • Bracketing wires are employed for preoperative localization of larger, calcific lesions, particularly those highly suggestive of malignancy.
    • While bracketing wires may aid in the complete excision of calcifications, they do not ensure clear surgical margins for cancer.
    • Further research may explore techniques to improve margin status when using bracketing wires.
