Axillary Reverse Mapping

Study acronym: ARM
Active, Not Recruiting Phase 2
View on ClinicalTrials.gov →
Summary
We hypothesize that variations in anatomic location of the arm lymphatic drainage system put the arm lymphatics at risk for disruption during a SLNB and / or ALND. Therefore, mapping the drainage of the arm during the procedure would decrease the likelihood of inadvertent disruption of the lymphatics and the subsequent development of lymphedema. A combination of radioactivity and blue dye will be used.
