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 ...
The first draining lymph note, the "sentinel", represents an existing or non-existing tumour of an entire lymph node region. The method has been validated using radionuclides and/or blue dye for breast cancer, malignant melanoma and also gastrointestinal tumours and gives a good detection rate and sensitivity.
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 ...
Lymphogram. Lymphography is a medical imaging technique in which a radiocontrast agent is injected, and then an X-ray picture is taken to visualise structures of the lymphatic system, including lymph nodes, lymph ducts, lymphatic tissues, lymph capillaries and lymph vessels. Lymphangiography is the same procedure, used only to visualize the ...
Donald Morton. 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.

MSOT may provide a non-radioactive, non-invasive alternative for examination of the metastatic status of the sentinel lymph node. Initial studies have shown that MSOT can detect sentinel lymph nodes based on indocyanine green (ICG) accumulation after injection in the tumor, as well as melanoma metastasis inside the lymph nodes.

CP-GEP. CP-GEP is a non-invasive prediction model for cutaneous melanoma patients that combines clinicopathologic (CP) variables with gene expression profiling (GEP). CP-GEP is able to identify cutaneous melanoma patients at low-risk for nodal metastasis who may forgo the sentinel lymph node biopsy (SLNB) procedure.
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; in a radical lymph node dissection ...
