To investigate the role and feasibility of sentinel lymph node biopsy (SLNB) in breast cancer patients with a local recurrence and no clinically positive axillary lymph nodes. ⋯ A SLNB in patients with locally recurrent breast cancer, no previous ALND and negative axillary lymph nodes is technically feasible and impacts on the ALND rate. In patients who at primary surgery received ALND, migration rate is significantly lower, aberrant migration is frequent and no clinically useful information has been obtained.
