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 sentinel node procedure (also termed sentinel lymph node biopsy ...
Sentinel node. In computer programming, a sentinel node is a specifically designated node used with linked lists and trees as a traversal path terminator. This type of node does not hold or reference any data managed by the data structure.
A linked list is a sequence of nodes that contain two fields: data (an integer value here as an example) and a link to the next node. The last node is linked to a terminator used to signify the end of the list. In computer science, a linked list is a linear collection of data elements whose order is not given by their physical placement in memory.
Axillary lymph nodes. The axillary lymph nodes or armpit lymph nodes are lymph nodes in the human armpit. Between 20 and 49 in number, they drain lymph vessels from the lateral quadrants of the breast, the superficial lymph vessels from thin walls of the chest and the abdomen above the level of the navel, and the vessels from the upper limb.
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.
Gamma probe. A gamma probe is a handheld device containing a scintillation counter for intraoperative use following injection of a radionuclide to locate sentinel lymph nodes by their radioactivity. [1] It is used primarily for sentinel lymph node mapping and parathyroid surgery. Gamma probes are also used for RSL (radioactive seed localization ...
Supraclavicular lymph nodes. Supraclavicular lymph nodes are lymph nodes found above the clavicle, that can be felt in the supraclavicular fossa. The supraclavicular lymph nodes on the left side are called Virchow's nodes. [1] It leads to an appreciable mass that can be recognized clinically, called Troisier sign. [2]
Lymph node dissection. ICD-9-CM. 40.2 - 40.5. [ edit on Wikidata] Lymphadenectomy, or lymph node dissection, is the surgical removal of one or more groups of lymph nodes. [ 1 ] It is almost always performed as part of the surgical management of cancer. In a regional lymph node dissection, some of the lymph nodes in the tumor area are removed ...
