Trial size 50 participants
Trial identifier NCT02313116, DxP 2012-02 (Part B)


This intraoperative study is a prospective study analyzing specimens from fifty subjects. Patients scheduled to undergo breast-conserving surgery will be recruited in accordance with the inclusion and exclusion criteria. The study period per subject is the time it takes to assess the ex vivo breast tissue sample using the study device. Image review will be conducted during surgery and compared to the margin status findings in the post-operative pathology report.
