MarginProbe© reduces the rate of re-excision following breast conserving surgery for breast cancer.

Purpose: A positive margin status after breast conserving surgery (BCS) is one of the strongest predictors for local recurrence of intraductal (DCIS) and invasive carcinoma. As much as 20-50 % of patients with BCS need to undergo a second operation to receive free margins. In this study we tested the clinical performance of MarginProbe© (Dune Medical Devices, Paoli, PA, USA), a device for the intraoperative evaluation of surgical margins.
