Study summary

This multi-center, prospective, open label study analyzed specimens from fifty subjects at two study sites. Patients scheduled to undergo breast-conserving surgery were recruited in accordance with the inclusion and exclusion criteria. The study period per subject was the time it took to assess the ex vivo breast tissue sample using the study device. Image review was conducted after surgery and compared to the margin status findings in the post-operative pathology report.

What researchers measure

Primary outcomes

  1. Patients With All Positive Margins Correctly Identified With the Device

    In this study, a patient had "positive margins" if tumor was identified at the true margin (i.e., the final margin or new margin) surface of at least one specimen by histology (0 mm, "tumor on ink").

    Time frame: one week after surgery

  2. Number of Margins With False Positive Device Readings

    Time frame: one week after surgery
