Detection of sentinel lymph node in breast cancer recurrence may change adjuvant treatment decision in patients with breast cancer recurrence and previous axillary surgery.

Use of sentinel lymph node dissection in patients with ipsilateral breast cancer recurrence is still controversial. The objective of this study is to evaluate the feasibility of the sentinel lymph node in breast cancer recurrence (SLNBR) and whether the positivity had impact in the adjuvant treatment. Between 2008 and 2012 we performed SLNBR in patients with ipsilateral breast tumor recurrence.
