"Mapping the drainage of the arm decreases the chances of unintended disruption of the lymph node system during surgery and reduces the risk of developing swelling in the arm," Klimberg said. "We are the first to study lymph node drainage in the arm and are now using the ARM procedure as standard procedure at UAMS."Klimberg will soon begin conducting training seminars on the procedure throughout the country. The seminars will be sponsored by the global medical device company Ethicon, a branch of Johnson & Johnson
Clinical Trials such as this one at MD Anderson are being planned to test the validity of ARM’s claims to decrease lymphedema.
Lymphazurin is a blue dye used usually in breast cancer surgery to trace the drainage pathway that flows to lymph nodes. The dye will travel to the lymph system and will end up in the lymph nodes that are draining the arm.In this study, lymphazurin will be used to find the drainage routes from your arm, rather than your breast.AXILLARY REVERSE MAPPING:
Before axillary lymph node surgery, your surgeon will inject lymphazurin into your arm. Your surgeon will watch how the dye flows and find the channels and nodes draining the arm. You will then have standard axillary lymph node (lymph nodes found under the arm) surgery. Any lymph nodes found that are dyed blue (lymph nodes that have traveled down the drainage pathways) that would normally be removed will be removed and sent to the pathology department. Pathologists will check the nodes to see if they have breast cancer cells in them. Also as part of routine care, all other axillary lymph nodes draining the breast will be removed and checked for breast cancer cells.This is an investigational study. Lymphazurin is FDA approved and commercially available. The use of lymphazurin with axillary reverse mapping is investigational.Up to 30 patients will take part in this study. All will be enrolled at M. D. Anderson.
