[Experiences with axillary reverse mapping].

Area of Science:

• Surgical Oncology
• Lymphedema Research
• Lymphatic System Imaging

Background:

• Axillary lymph node dissection (ALND) is a standard procedure for breast cancer staging.
• ALND can lead to significant postoperative morbidity, including lymphedema.
• Preserving lymphatic drainage is crucial for minimizing these complications.

Purpose of the Study:

• To evaluate the efficacy of Axillary Reverse Mapping (ARM) in preserving lymphatic channels and glands.
• To assess the impact of ARM on reducing postoperative symptoms following ALND.
• To determine the added value of ARM in patients undergoing ALND.

Main Methods:

• A randomized multicenter study was conducted.
• Axillary Reverse Mapping (ARM) technique was employed to map lymphatic drainage.
• Lymphatic channels and glands of the upper extremities were preserved during ALND in the intervention group.

Main Results:

• The study demonstrated statistically significant reductions in postoperative symptoms for patients who underwent ARM.
• Preservation of upper extremity lymphatics via ARM led to fewer adverse outcomes.
• ARM proved beneficial for patients requiring ALND.

Conclusions:

• Axillary Reverse Mapping (ARM) is an effective technique for preserving lymphatic function during ALND.
• ARM significantly decreases postoperative morbidity, particularly lymphoedema.
• ARM provides substantial benefits for patients undergoing ALND, despite its declining indication.
