Can Sentinel Lymph Node Biopsy (SLNB) be Performed in a Patient that has had Breast Conservation with SLNB?


  • In 2014, updated The American Society of Clinical Oncology (ASCO) Guidelines were published on the use of SLNB for early-stage breast cancer:
      • A strong recommendation was made for reoperative SLNB:
        • In women who have undergone prior breast or axillary surgery.
      • There are now multiple reports of successful second SLNB in patients with a local breast cancer recurrence following a previous SLNB or even axillary lymph node dissection (ALND):
        • A recent systematic review and meta-analysis of studies on repeat SLNB in locally recurrent breast cancer found that sentinel node identification:
          • Was successful in 452 of the 692 patients (65.3%):
            • This percentage was significantly higher in patients who had undergone previous SLNB compared to previous ALND:
              • 81.0% vs 52.2%.
          • In most of these studies:
            • A dual tracer technique, with use of blue dye and radiocolloid, was performed.
          • Aberrant drainage pathways:
            • Were demonstrated in 43% of patients:
              • More frequently after previous ALND than after previous SLNB:
                • 69.2% vs 17.4%.
              • Lymphoscintigraphy, including examination of the contralateral axilla, should be performed if repeat SLNB is planned:
                • Given that these patients often have alternate drainage patterns.
