Computed Optical Margin Assessment for Breast Cancer Surgery, Phase I (Part A)

December 12, 2014 updated by: Diagnostic Photonics, Inc.
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.

Measure Description
Time Frame
Patients With All Positive Margins Correctly Identified With the Device
Time Frame: one week after surgery
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").
one week after surgery
