Sentinel lymph node biopsy in patients with ductal carcinoma in situ

Abstract
Sentinel lymph node (SLN) biopsy for the treatment of ductal carcinoma in situ (DCIS) is not necessary and generally should be limited to those patients with a core needle biopsy diagnosis of DCIS who are undergoing mastectomy. Used in this way, SLN biopsy will spare the majority of patients with occult invasive tumor the need for axillary lymph node dissection.
