Diagnostic Photonics, Inc.
  Purpose
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.

Condition Intervention
Breast Cancer Device: Optical coherence tomography

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: Computed Optical Margin Assessment for Breast Cancer Surgery, Phase I (Part A)

Primary Outcome Measures:
  • 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").

  • Number of Margins With False Positive Device Readings [ Time Frame: one week after surgery ]

Enrollment: 50
Study Start Date: December 2012
Study Completion Date: April 2014
Primary Completion Date: May 2013 (Final data collection date for primary outcome measure)
Intervention Details:
    Device: Optical coherence tomography
    Optical coherence tomography was used to image ex vivo breast tissue specimens.
