Sentinel lymph node removal

What is a sentinel lymph node biopsy? A sentinel lymph node biopsy (SLNB) is a procedure in which the sentinel lymph node is identified, removed, and examined to determine whether cancer cells are present. It is used in people who have already been diagnosed with cancer.

Your Recovery

Your breast and underarm area may be slightly swollen. This may last a few days. You should feel close to normal in a few days. The incision the doctor made usually heals in about 2 weeks.

How many lymph nodes removed in sentinel node biopsy?

Typically, there are a few sentinel nodes, and all are removed. The sentinel nodes are sent to a lab where they are examined under a microscope for signs of cancer. Often the sentinel node biopsy is done at the same time as surgery to remove the cancer.

What is the difference between a sentinel node and a lymph node?

Sentinel nodes are the first lymph nodes where cancer cells might spread from a tumor. Lymph nodes are small organs that “filter” fluid in the body and help protect you from illness. The word “sentinel” means a guard or someone keeping watch.

What happens if sentinel node is positive?

A positive result means there are cancer cells in the sentinel nodes. This means the cancer has started to spread. Your doctor will talk to you about further treatment. You'll also have scans to see if the cancer has spread anywhere else.

What are the long-term side effects of sentinel lymph node removal?

Lymphedema. A possible long-term effect of lymph node surgery is swelling in the arm or chest called lymphedema. Because any excess fluid in the arms normally travels back into the bloodstream through the lymph system, removing the lymph nodes sometimes blocks drainage from the arm, causing this fluid to build up.

How many sentinel nodes should be removed?

The mean number of SLNs removed at surgery in breast cancer patients ranges from 1.2 to 3.4 SLNs, and the total number from 1 to 15 SLNs. Because of the multiple factors involved in SLND, the number of SLNs that should be removed to accurately predict lymph node status remains controversial.

Do lymph nodes grow back after removal?

A team including University of Georgia researchers has for the first time documented the regrowth of surgically removed pathways in the lymphatic system, a network of vessels designed to pump away inflammatory fluids and defend the body against infection.

How many sentinel nodes are in each breast?

Sentinel node biopsy has become a cornerstone of breast cancer management and has been shown to accurately stage the axilla in patients with breast cancer. Although the median number of SLNs identified is 2, more than 3 SLNs are found in 17.9% of cases.

What percentage of sentinel lymph node biopsy is positive?

A preoperative negative axilla will undergo sentinel lymph node biopsy and, in around 25–30% of cases, there are metastasis within the axillary lymph nodes and the patient will be deemed to have a positive axilla.

What precautions should be taken after sentinel lymph node removal?

Avoid strenuous activities, such as biking, jogging, weightlifting, or aerobic exercise, until your doctor says it is okay. This includes housework, especially if you have to use your affected arm. You will probably be able to do your normal activities in 3 to 6 weeks.

How long does it take for lymph nodes to heal after radiation?

You may start to notice side effects about 2 weeks after you start treatment. They may get worse during treatment, but they will slowly get better over several weeks after you finish treatment.

How long does pain last after lymph node removal?

Some mild swelling after surgery is normal. This swelling may last for up to 6 weeks. It's often temporary and will gradually go away. You may also feel pain or other sensations such as twinges and tingling after your surgery.

What to expect after lymph node removal?

Right after the surgery you will probably feel weak, and your shoulder area will feel sore and stiff for a few days. It may be hard to move your arm and shoulder in all directions. Your doctor or physical therapist will teach you some arm exercises. You now have a higher chance of swelling in the affected arm.

How do you sleep after lymph nodes removal?

Sleep in a position that is comfortable for you. Consider placing your arm on a pillow when you are sleeping. Avoid sleeping directly on your chest.

Do lymph nodes grow back after removal?

A team including University of Georgia researchers has for the first time documented the regrowth of surgically removed pathways in the lymphatic system, a network of vessels designed to pump away inflammatory fluids and defend the body against infection.

How painful is sentinel node injection?

During mapping, the injection of a radioactive tracer or isosulfan blue dye to differentiate the SLN is acutely painful. The use of the eutectic mixture of lidocaine and prilocaine (EMLA) cream to reduce tracer injection pain has been reported anecdotally.
