Drug Administration recently approved Lymphoseek (technetium Tc 99m
tilmanocept) Injection, a radioactive diagnostic imaging agent that helps
doctors locate lymph nodes in patients with breast cancer or melanoma who are
undergoing surgery to remove tumor-draining lymph nodes. U.S.
Lymph nodes filter lymphatic fluid that flows from the body’s tissues. This fluid may contain cancer cells, especially if the fluid drains a part of the body containing a tumor. By surgically removing and examining the lymph nodes that drain a tumor, doctors can sometimes determine if a cancer has spread.
Lymphoseek is an imaging drug that helps locate lymph nodes; it is not a cancer imaging drug. Lymphoseek is the first new drug used for lymph node mapping to be approved in more than 30 years. Other FDA-approved drugs used for lymph node mapping include sulfur colloid (1974) and isosulfan blue (1981).
