The Lymph Node Locator is an entirely new type of device for use in the surgical
pathology gross lab: a mechanical device for efficient lymph node harvesting.
The Lymph Node Locator is a portable, hand operated device that is easy to use
and modernizes lymph node harvesting. The Lymph Node Locator reduces
bench time by making manual palpation unnecessary. It improves patient care
by facilitating the retrieval of 100% of lymph nodes from cancer resection
specimens – not the current yield of approximately 50% of resected lymph
nodes. Lymph node staging for cancer becomes more accurate with near zero
false negative staging. Cost and time savings accrue from the use of the Lymph
Node Locator : reduced numbers of cassettes for many cases, no “second look“
procedures, and reduced occurrence of delayed case sign out.
The Lymph Node Locator is multifunctional : it reduces tissue volume ,
facilitates serial sectioning, and facilitates easy loading of cassettes. The first
step of processing reduces the tissue volume by 90% and sizes the remaining
tissue into a precisely sized block with dimensions calibrated to fit into standard
tissue cassettes. The second step facilitates serial sectioning of the tissue block
with one cut per each section (no additional time consuming trimming of tissue
is necessary). The final step, cassetting, involves only picking up cross sections
and placing them into a cassette. Cassetting of the serial sections can be in
sequence rather than random (sequential sections reduce the possibility of
double counting of lymph nodes and/or metastases).
The Lymph Node Locator is especially useful and effective for rectal carcinoma
resections following neoadjuvant therapy. Achieving the recommended minimum
of 12 lymph nodes is often difficult after neoadjuvant therapy, but the Lymph
Node Locator ensures evaluation of 100% of the resected lymph nodes,
regardless of their size post therapy. The device permits evaluation of all of the
small (5 mm or less) lymph nodes where there is a high possibility of metastatic
colorectal cancer, but a low probability of this size lymph node being detected
by manual palpation ( very small lymph nodes with and without metastases are
often not detected by manual palpation, and therefore, are not evaluated
histologically).
