The Utility of Axillary Nodal Evaluation in Women with Ductal Carcinoma In Situ of the Breast with Microinvasion

Abstract

The utility of axillary nodal evaluation in patients with ductal carcinoma in situ of the breast with microinvasion (DCISM) is unclear. Some studies have shown a 6-28% risk of axillary nodal involvement in these patients but others have shown no axillary involvement. In view of this uncertainty, we sought to investigate the risk of nodal involvement in a large cohort of patients treated with breast conserving therapy at a single institution.
