Achieving negative margins is crucial for breast conservation therapy (BCT) success and reducing local recurrence. Advanced imaging and intraoperative pathology assessment can improve margin status in breast cancer surgery.

Area of Science:

  • Surgical Oncology
  • Radiology
  • Pathology

Background:

  • Negative margin status is now essential for breast-conserving surgery (BCS), as positive margins increase local recurrence rates.
  • Historically, consensus on the necessity of negative margins was lacking, but current practice emphasizes their importance for oncologic and cosmetic outcomes.
  • Preoperative factors like large tumor size and positive lymph nodes predict difficulty in achieving clear margins.

Purpose of the Study:

  • To review advancements in margin evaluation techniques for breast cancer surgery.
  • To highlight the role of preoperative imaging and intraoperative assessment in achieving negative margins.
  • To discuss strategies for improving surgical outcomes and reducing recurrence through optimal margin control.

Main Methods:

  • Review of current literature and consensus on margin evaluation in breast cancer surgery.
  • Discussion of preoperative imaging techniques, including RODEO-MRI, for predicting margin status.
  • Exploration of intraoperative assessment methods, such as ultrasound and cytology, for guiding surgical excision.

Main Results:

  • RODEO-MRI can predict the likelihood of achieving negative margins and better define tumor extent for surgical planning.
  • Intraoperative ultrasound may aid in excising non-palpable and palpable tumors.
  • Intraoperative cytological assessment offers potential for real-time feedback to surgeons regarding margin status, unlike frozen section analysis.

Conclusions:

  • Achieving negative margins is critical for successful breast conservation therapy and minimizing local recurrence.
  • Preoperative and intraoperative tools are evolving to enhance the surgeon's ability to obtain negative margins.
  • Improved margin assessment strategies can positively impact breast cancer surgical outcomes and recurrence rates.
