This observational study finds that axillary reverse mapping reduces lymphedema severity in breast cancer, implying careful case selection is essential.
Arm width difference was less in the ARM group as compared to the non-ARM group at serial follow-ups. Hence, ARM reduces the severity of lymphedema but does not completely prevent it. It is difficult to make it a routine due to lymphatic cross over and incomplete oncologic clearance. Proper case selection is needed to derive the benefit of ARM.
