184P Comparison of survival outcomes between repeat sentinel lymph node biopsy and axillary lymph node dissection among patients with ipsilateral breast tumor recurrence: A SEER population-based study

Abstract

Early-stage breast cancer patients are increasingly choosing breast-conserving surgery (BCS) and sentinel lymph node biopsy (SLNB). There is, however, a 14.3% to 20% chance of developing local recurrences. A lack of studies has assessed the survival benefit of repeat sentinel lymph node biopsy (rSLNB) over axillary lymph node dissection (ALND) in patients with ipsilateral breast tumor recurrence (IBTR).
