Clinical examinations and imaging methods are not sufficiently reliable for an exact staging of axillary nodes in breast cancer. The sentinel node biopsy concept is a minimally invasive procedure to locate and remove the first and important nodes responsible for draining a tumor. Histologic examinations using immunohistochemical methods permit more accurate staging than hematoxylin and eosin staining alone. Between 4/1997 and 9/1998 a total of 62 patients with 65 breast cancers underwent surgery. The sentinel node procedure with radio tracers and/or blue dye was performed in patients with clinically negative or unclear positive findings in the axilla, with a primary tumor size less than 5 cm; 11 patients had received preoperative chemotherapy. The sentinel node biopsy was followed by axillary dissection in 44 cases. In 58 (89%) cases we found one or more (on an average 1.4) sentinel nodes with radio tracers (in 73%) and/or the blue dye method (in 85%). Axillary nodal status was correctly predicted in 43 of 44 (97.7%) cases; only in one patient was the sentinel node false negative. After preoperative chemotherapy sentinel nodes were found in 9 cases; all of these were predictive. Micrometastases were found in two patients only after cytokeratine staining. Our results concur with the experience of other study groups in regard of sentinel node biopsy. The sentinel node concept is a fascinating method; its importance in breast cancer treatment appears to be comparable with introduction of breast saving surgery in the 1980's. |
