Prospective Study Evaluating Oncological Safety of Axillary Reverse Mapping

Background Axillary reverse mapping (ARM) is a new technique developed with the aim of reducing lymphedema rates by preserving lymphatic drainage of the upper limbs during sentinel lymph node biopsy and axillary lymph node dissection (ALND). However, it is unclear whether preservation of these lymph...

Description
Summary:Background Axillary reverse mapping (ARM) is a new technique developed with the aim of reducing lymphedema rates by preserving lymphatic drainage of the upper limbs during sentinel lymph node biopsy and axillary lymph node dissection (ALND). However, it is unclear whether preservation of these lymph nodes affects oncological risk. The present study evaluated the presence of metastases in ARM nodes. Methods A total of 45 patients underwent ARM during ALND. Blue dye was used for ARM nodes localization. All axillary lymph nodes, including ARM nodes, were removed and sent separately for pathological evaluation of metastases. Results ARM identification was achieved in 40/45 patients (88.9 %). The average number of removed ARM nodes was 1.9. ARM nodes metastasis occurred in 10 of 40 patients (25 %). Patients with an axilla extensively affected by cancer had an elevated risk of metastasis to the arm’s lymph nodes ( p
