Extent of Microinvasion in Ductal Carcinoma In Situ is not Associated with Sentinel Lymph Node Metastases
Carcinoma, Intraductal, Noninfiltrating
Neoplasm Recurrence, Local
Sentinel Lymph Node Biopsy
Even with large numbers, there was no higher risk of nodal involvement with ≥2 foci of microinvasion compared with 1 focus. Number of microinvasive foci and results of SLNB appear to be used in decision making for systemic therapy. Prognosis is excellent.
