Outcomes for women with ductal carcinoma-in-situ and a positive sentinel node: a multi-institutional audit.
A positive sentinel lymph node (SLN) has been reported in 6% to 13% of patients with ductal carcinoma in situ (DCIS). Although it is well established that nodal status for invasive disease is prognostically important, the clinical relevance of a positive SLN in patients with DCIS remains undetermined. ⋯ SLN biopsy for high-risk DCIS patients is a mean of detecting those who may have unrecognized invasive disease and therefore are at risk for distant disease.
