title: Sentinel lymph node biopsy in the management of breast cancer.
abstract: Sentinel node localization is the second most important development in this century after conservative lumpectomy for the treatment of early breast cancer. The sentinel node mapping is a new multidisciplinary approach for staging of axilla in an accurate and less morbid way as compared to axillary node dissection. Sentinel lymph node biopsy in patients with breast cancer has been adopted rapidly into clinical practice. The accuracy of sentinel lymph node biopsy is more than 95%, when performed meticulously (by an experienced multidisciplinary team) with proper patient selection. Sentinel lymph node biopsy is most widely used for both palpable and non-palpable T1 and T2 tumors. Recent studies show application of sentinel lymph node technique in patients with locally advanced breast cancer and after neoadjuvant chemotherapy. Therefore, sentinel lymph node biopsy technique has application in developing countries and other countries where screening for breast cancer is not common and most patients present relatively in advanced stage of the disease. Several aspects of the sentinel lymph node biopsy including technique, case selection, pathologic analysis and accuracy with supportive important studies published in the literature will be discussed in this review.
