The concept of the sentinel lymph node is important because of the advent of the sentinel lymph node biopsy technique, also known as a sentinel node procedure. This technique is used in the staging of certain types of cancer to see if they have spread to any lymph nodes, since lymph node metastasis is one of the most important prognostic signs .
Such spread typically results in Troisier's sign, which is the finding of an enlarged, hard Virchow's node. [1] The left supraclavicular nodes are the classical Virchow's node because they receive lymphatic drainage of most of the body (from the thoracic duct) and enters the venous circulation via the left subclavian vein. The metastasis may ...
Sentinel systems involve a network of reporting sites, typically doctors, laboratories and public health departments. Surveillance sites must offer: [3] commitment to resource the program; a high probability of observing the target disease, a laboratory capable of systematically testing subjects for the disease, experienced, qualified staff.

The sentinel node market experienced high growth in the early and mid-1990s, starting with melanoma sentinel node surgical search and breast cancer sentinel node staging; both are currently considered standards of care. [4] The use of a radioactive tracer, rather than a coloured dye, was proposed in 1984. [5] [6]
