ARM: Axillary Reverse Mapping
For women undergoing surgery for breast cancer, the removal and analysis of the lymph nodes under the armpit (called sentinel node biopsy and/or axillary node dissection) remains the most important factor in predicting survival. In the past, this procedure removed the lymph nodes and most of the fat and tissue in the armpit, putting the lymph node system at risk of disruption, often leading to ‘lymphedema’, or swelling of the arm.
Dr. V. Suzanne Klimberg, Director of the Breast Cancer Program at UAMS, has pioneered the use of the ARM Procedure at the Winthrop P. Rockefeller Cancer Institute (WPRCI). This procedure distinguishes lymphatics draining the arm from those draining the breast so that the surgeon can identify and preserve the arm lymphatics. We believe that this ‘mapping’ of the drainage of the arm decreases the chances of unintended disruption of the lymph system during surgery, thereby reducing the risk of lymphedema.
Blue dye is injected into the upper arm, then travels through the lymphatics allowing the surgeon to distinguish between those draining the arm and those draining the breast.
The ARM Study is currently enrolling subjects at UAMS/WPRCI. If you are interested in participating, or would like to know more, please contact:
