What Is a Sentinel Node Biopsy?

A sentinel lymph node biopsy is a type of surgery sometimes recommended for skin cancer patients with melanoma. The purpose of the surgery is to find out if melanoma has spread to the lymph nodes. A sentinel lymph node biopsy is usually performed in a hospital operating room and is done at the same time as the surgical removal of the melanoma.

Before the surgery, a radioactive dye is injected into the skin at the site of the cancer. Sensors are used to follow the path of the dye to the lymph nodes. This process identifies which lymph nodes are most likely to have melanoma if the skin cancer has spread there. Then your surgeon removes the melanoma and the lymph nodes identified by the dye. The lymph nodes are checked under the microscope for the presence of skin cancer cells.

Sentinel lymph node biopsy is not usually recommended for melanomas with a Breslow’s depth of less than 1 mm. If the Breslow’s depth of the skin cancer lesion is greater than 1 mm, a sentinel lymph node biopsy may be recommended.

Not all physicians agree about how important it is for skin cancer patients to have a sentinel lymph node biopsy performed, as the procedure has not been shown conclusively to increase the chances of curing melanoma. It does, however, provide valuable information for predicting how likely it is that the melanoma could result in death.
