BACKGROUND: The axillary reverse mapping (ARM) technique, identify and preserve arm nodes during sentinel lymph node biopsy (SLNB) or axillary lymph node dissection (ALND), was developed to prevent breast-cancer related lymphedema (BCRL) remains controversial. METHODS: A comprehensive search of Medline Ovid, Pubmed, Web of Science and the Cochrane CENTRAL databases was conducted from the inception till January 2020. The key word including "breast cancer", "axillary reverse mapping", and "lymphedema". Stata 15.1 software was used for the meta-analysis. CONCLUSIONS: ARM was found to significantly reduce the incidence of BCRL. The selection of patients for this procedure should be based on their axillary nodal status. Preoperative neoadjuvant chemotherapy has no significant impact on the ARM lymph node metastasis rate.
