Lymphadenectomy is surgery to remove
lymph nodes. This surgery is done to see if cancer has spread to a lymph node. Some lymph nodes are located near the surface of the body, while others are deep in the abdomen or around organs, such as the heart or liver. Lymphadenectomy is also done to remove melanomathat has spread only to the lymph nodes and to prevent melanoma from spreading farther (metastasizing).
General anesthesiais usually used for a lymphadenectomy. An incision is made in the skin over the lymph nodes to be removed. The type and depth of the incision varies depending upon the location of these lymph nodes. The lymph nodes are removed along with nearby lymphatic tissue and some underlying soft tissue.
Recovery depends on the extent of the surgery and the site where the lymph nodes were removed.
Lymphadenectomy is done to remove lymph nodes that may have melanoma in them.
Wide local excision and lymphadenectomy may cure some melanomas that have spread to the nearby lymph nodes but no farther.
Surgery to remove lymph nodes can cause many side effects. The risks of lymphadenectomy include:
- Buildup of fluid at the site of surgery (seroma).
- Swelling of a limb affected by removal of the lymph nodes (lymphedema).
- Numbness, tingling, or pain in the surgical area.
- Breakdown (sloughing) of skin over the area.
The decision to have a lymphadenectomy is not simple. It depends on your age, the location and thickness of the melanoma, results of the
sentinel node biopsy, and other possible treatments. Discuss these issues with your doctor before deciding whether to have a lymphadenectomy.
Not all lymph node enlargement means involvement with melanoma. Other conditions that cause lymph node swelling, such as acne or infection, could occur at the same time as the melanoma. Such conditions should be ruled out before lymphadenectomy is done.
Swelling after surgery (
lymphedema) can be prevented or controlled by use of antibiotics, support stockings (also called compression stockings), massage, and diuretics.
Lymphadenectomy usually is not needed if melanoma has not spread to the lymph nodes.
