Sentinel lymph node biopsy has become an importatnt tool for axillary lymph node staging in women with early-stage breast cancer. The sentinel node (SN), "guardian node," is the first node that drains the tumor. It is assumed that this node is the first location to which the tumor spreads by lymphatics. In certain cases, more of these nodes may be present. In breast cancer, the sentinel node is usually found in the axilla, although in a small percentage of cases it can be present wherever in the lymphatic system of the breast. The procedure is associated with much less morbidity than axillary dissection, and it has become the axillary staging procedure of choice for many surgeons. It appears that blue dye or radiocolloid, or both, may be used to identify the sentinel node effectively. A variety of injection techniques have been verified succesfully, and many factors previously thoughtto affect the accuracy of the procedure have been shown to be of limited signficance. The indications for the procedureare expanding, and the histopathological evaluation of the sentinel node have been clarified. The positive result of imunohistochemical evaluation of the sentinel node have prognostic significance and should alter the therapy. The aim of the model phase was to test if the location of the tumor and its sentinel...
