BACKGROUND: The axillary reverse mapping (ARM) technique has been proposed to prevent arm lymphedema. We conducted this study to assess the feasibility of the technique and the outcomes of patients with neoadjuvant chemotherapy (NAC).
METHODS: From July 2009 to May 2010, a prospective study was performed in 36 patients with breast cancer undergoing an ALND. The ARM technique was performed injecting 3 cm(3) of Patent Blue in the ipsilateral arm. Of the 36 patients, 29 patients received NAC previously to the ARM and 7 patients had an ALND and ARM performed as first treatment for positive axillary nodes.
RESULTS: The identification rate of blue nodes was 83.3% (30 patients). Sentinel lymph node (SLN) was performed in 15 of 29 (42%) patients in the NAC group. Of these 15, two patients (13%) had a concordance between the blue and the hot node. Blue nodes were positive in 4 (13%) of the 30 patients.
CONCLUSIONS: The ARM technique is feasible in patients undergoing NAC. Patients with extensive nodal involvement have increased risk of having positive blue nodes. More studies are needed to assess the subgroup of patients with positive axilla that may have the blue node spared without compromising the oncological treatment.
