Fluorescence technique for detecting sentinel lymph nodes during surgery #MedEd

Sentinel lymph node identification in #surgery refers to the process of identifying and removing the first lymph node(s) that cancer cells are most likely to spread to from a primary #tumor. This procedure is commonly performed in oncologic surgeries, particularly in #breast #cancer and #melanoma cases, to determine the extent of lymph node involvement and guide further #treatment decisions. The sentinel lymph node(s) is the initial lymph node that receives lymphatic drainage from the primary tumor site. By localizing and examining this node, surgeons can assess whether cancer cells have spread beyond the primary tumor and into the regional lymphatic system. This technique helps avoid unnecessary removal of non-involved lymph nodes, reducing surgical morbidity while providing accurate staging information. Various methods are employed to identify the sentinel lymph node during surgery. The most commonly used technique involves the injection of a tracer substance, such as a radioactive material or a blue dye, at or near the tumor site. The tracer travels through the lymphatic vessels to the sentinel node(s), allowing surgeons to visually or instrumentally locate and remove it/them. Once the sentinel lymph node(s) is removed, it is sent for pathological examination to determine if cancer cells are present. If the sentinel node(s) is negative for cancer involvement, it is highly likely that the remaining lymph nodes in the area are also disease-free. However, if the sentinel node(s) is positive for cancer, further lymph node dissection or adjuvant therapies may be considered. The sentinel lymph node identification technique has revolutionized the management of certain cancers, providing accurate staging information while minimizing unnecessary surgeries. Learn more at

Indocyanine green

We can also use SentiMag for the same

is this radioactive??

I thought id never see fluorescence tech. in real life, it seems that studying analytical is good after all.

@scientissimum

Very nice 👍👍
