Research Question(s)

Clinical Practice

  1. Should SLNB be the recommended standard of care for women and men with proven breast cancer, whose clinical presentation is suggestive of early-stage disease?
  2. How should the results of SLNB be utilized in clinical practice?
    1. Can level I/II axillary lymph node dissection (ALND) be avoided in patients with negative findings on sentinel lymph node biopsy (SLNB)?
    2. Is level I/II ALND necessary for all patients with positive findings on SLNB?
  3. What is the role of SLNB in special circumstances in clinical practice? (special circumstances include large and locally advanced invasive tumours, multicentric tumours, inflammatory breast cancer, ductal carcinoma in situ (DCIS), older age (65 years or more), obesity, male breast cancer, pregnancy, evaluation of the internal mammary nodes, presence of suspicious palpable axillary nodes, prior breast or axillary surgery, and preoperative systemic therapy).

  5. What are the potential benefits and harms associated with SLNB?

Technical Aspects of SLNB

  1. What is the recommended mapping technique for SLNB?
  2. What operative technique is recommended?
  3. What is the recommended technique for pathological processing, handling, and reporting?
