What is Lymphoseek?

Lymphoseek is a radioactive diagnostic agent indicated with or without scintigraphic imaging for: Lymphatic mapping using a handheld gamma counter to locate lymph nodes draining a primary tumor site in patients with solid tumors for which this procedure is a component of intraoperative management.

Is lymphoseek radioactive?

Lymphoseek is a radioactive drug and should be handled with appropriate safety measures to minimize radiation exposure [see Warnings and Precautions (5.2)]. Use waterproof gloves, effective radiation shielding, and appropriate safety measures when preparing and handling Lymphoseek.

What is a lymphoscintigraphy?

Lymphoscintigraphy is a special type of nuclear medicine imaging that provides special pictures of the lymphatic system, which transports fluid throughout your immune system. Lymphoscintigraphy is often used to identify the sentinel lymph node, or the first node to receive the lymph drainage from a tumor.

How does lymphoseek work?

LYMPHOSEEK transits through the lymphatic vessels and accumulates in lymph nodes draining from a primary tumor. The mannose components of LYMPHOSEEK have a high affinity for the CD-206 receptor protein, which are found in high concentrations on the surface of macrophages and dendritic cells.

What is a sentinel node injection?

The sentinel nodes are the first few lymph nodes into which a tumor drains. Sentinel node biopsy involves injecting a tracer material that helps the surgeon locate the sentinel nodes during surgery. The sentinel nodes are removed and analyzed in a laboratory.

What are sentinel lymph nodes?

A sentinel lymph node is defined as the first lymph node to which cancer cells are most likely to spread from a primary tumor. Sometimes, there can be more than one sentinel lymph node.

What is NM lympho injection?

Lymphoscintigraphy is a special type of nuclear medicine imaging that provides pictures called scintigrams of the lymphatic system. Nuclear medicine uses small amounts of radioactive material called radiotracers.

Is lymph node mapping painful?

Sentinel lymph node biopsy (SLNB) has been reliably accurate as a minimally invasive surgical alternative for identifying lymphatic breast metastasis. During mapping, the injection of a radioactive tracer or isosulfan blue dye to differentiate the SLN is acutely painful.

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.

Do lymph nodes grow back after removal?

The surgery reconnects the system. “As the reconnected lymph nodes start working, they send signals to the body to start recreating channels that have not been working,” Dr. Manrique says. “The procedure sets in motion the regeneration of the lymphatic system and ultimately the circulation of the lymphatic fluid.

Can a surgeon tell if a lymph node is cancerous?

Lymph nodes deep in the body cannot be felt or seen. So doctors may use scans or other imaging tests to look for enlarged nodes that are deep in the body. Often, enlarged lymph nodes near a cancer are assumed to contain cancer. The only way to know whether there is cancer in a lymph node is to do a biopsy.

What are the signs that you have a cancerous lymph node?
