Sentinel node biopsy or limited oriented axillary dissection (LOAD) in early breast cancer

The oriented limited axillary dissection technique, combined with frozen section histological examination, avoids the usually unnecessary secondary operations in small breast cancers, in which axillary lymph node invasion rarely exceeds more than two nodes. This technique requires surgeons experienced in axillary surgery and conventional sentinel lymph node biopsy. It needs to be validated on a larger scale by a multicentre randomized prospective trial comparing LOAD to conventional axillary lymph node dissection.
