The sentinel lymph node is the hypothetical first lymph node or group of nodes draining a cancer. In case of established cancerous dissemination it is postulated that the sentinel lymph nodes are the target organs primarily reached by metastasizing cancer cells from the tumor .
The concept of sentinel lymph node biopsy in breast surgery is one of the major contributions of Giuliano to modern day breast cancer management. [3] He inherited the idea of sentinel node biopsy from his mentor Morton in early 1990s, who at that time was using the technique for skin melanoma management.
To locate the draining lymph nodes or sentinel lymph nodes from a breast cancer tumour, a Technetium-99m based radiopharmaceutical is common. This may be a nanocolloid or sestamibi . [ 7 ] Although imaging with a gamma camera may also take place, the idea of a small gamma probe is that it can be used to identify lymph nodes (or other sites ...
The sentinel lymph node biopsy (SLNB) is the standard of care for detecting nodal metastases in cutaneous melanoma patients and has been the most informative prognostic factor to guide subsequent treatment. However, ~85% of patients undergoing this procedure have no evidence of nodal metastasis.
The lymph nodes located in the axilla area that are affected by breast cancer are called the guardian or sentinel lymph nodes. Lymph nodes are essential to the lymphatic/immune system due to their main function of filtering unrecognized particles and molecules. [ 4 ]
The detection of micrometastases in the sentinel lymph nodes (SLN) is the primary indicator of its spread to the regional lymph nodes, bone marrow, peripheral blood and ultimately to distant metastatic sites, since they are the first of the nodes that cancer would travel to. [3]
Donald Lee Morton (September 12, 1934 – January 10, 2014) was an American surgical oncologist who was best known for developing sentinel lymph node evaluation, a procedure that, by some estimates, saves the U.S. healthcare system nearly $4 billion annually in the treatment of melanoma and breast cancer.

These nodes, commonly referred to as "Sentinel Lymph Nodes," are removed and analyzed for the presence of malignant cells. Lymphatic Mapping provides an accurate staging procedure that can help ...
