Surgery Overview
Lymphadenectomy is surgery to remove cancerous
lymph nodes. 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 done to cure
melanoma that has spread only to the lymph nodes and
to prevent melanoma from spreading farther (metastasizing).
General anesthesia is 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.
What To Expect After Surgery
Recovery depends upon the extent of the surgery and the site where
the lymph nodes were removed.
Why It Is Done
Lymphadenectomy may be done for stage II or III melanoma to remove
lymph nodes that have melanoma in them.
How Well It Works
Not all studies show that lymphadenectomy increases survival. But
many experts believe it gives the best chance of a cure for people who have
melanoma with involvement of regional lymph nodes but with no evidence of
distant metastases.1
Risks
Surgery to remove lymph nodes can cause many side effects. The
risks of lymphadenectomy include:
- Buildup of fluid at the site of surgery
(seroma).
- Infection.
- 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.
What To Think About
The decision to have a lymphadenectomy is not simple. It depends on
your age, the location and thickness of the primary melanoma, results of the
sentinel node biopsy, and other possible treatments.
Discuss these issues with your health professional before deciding whether to
have a lymphadenectomy.
Not all lymph node enlargement indicates 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, elastic stockings,
massage, and
diuretics.
Lymphadenectomy usually is not needed if melanoma has not spread to
the lymph nodes.
