Interventional Procedures

interventional procedures

Sentinel lymph node mapping and sentinel lymph node biopsy (SLNB) is a minimally invasive technique which allows the surgeon to excise and meticulously examine the primary draining lymph nodes after those have been identified by radionuclide procedure. The principle underlying sentinel node surgery is rooted in the concept that the sentinel node is the first draining lymph node from a tumor and is predictive of lymph nodal metastasis.

The use of radio-nuclide injection close to or into the tumor, nuclear imaging to visualize the sentinel lymphnode, detection and excision with the help of a handheld gamma probe to identify sentinel lymph nodes and its histopathological examination completes the procedure. It is helpful in early breast cancer and head neck malignancies. SLNB provides more accurate prognostic information for these patients and identifies those patients that may benefit from additional treatment to the lymphatics.
