(1) The procedure is highly selective as a method for detecting the lymph node or nodes most likely to harbor metastatic carcinoma, Consequently, the staging of the axilla can be accomplished by this method without the morbidity of a full axillary dissection
It is also well established that between 20% and 25% of patients designated as node negative by routine pathologic examination will eventually develop metastatic disease.[1-6] It is thought that improved detection of occult axillary disease may result in more accurate assessment of the prognosis of breast cancer patients, and several methods that increase the sensitivity of detection of micrometastatic disease in axillary lymph nodes have been studied.[7,16-26] For this reason, the use of the SLN as representative of the rest of the axillary nodes is very appealing; this limited material is amenable to detailed histologic evaluation without the prohibitive labor cost requirements associated with such detailed evaluation of full axillary dissections
