The role of sentinel lymph node biopsy in ductal carcinoma in situ

Axillary lymphadenectomy is an overtreatment for patients with DCIS. Performing a SLNB during the initial procedure may avoid a second operation in some DCIS patients who are diagnosed with occult invasive disease at their definitive operation. When predictors of hidden invasive disease are clarified by further study, SLNB may be used in the management of selected high-risk DCIS patients.
