Evaluation of Breast Cancer Surgical Margins Using Optical Spectroscopy
This study will apply optical spectroscopy to intraoperative margin assessment during surgery for breast cancer. We hypothesize that a combination of fluorescence spectroscopy and diffuse reflectance spectroscopy will reliably detect involved surgical margins. Twenty patients with ductal carcinoma in-situ will undergo a standard lumpectomy followed by scanning with a sterile optical spectroscopy probe. Frozen sections from the surgical cavity will be used to evaluate the margins. Optical spectroscopy data will be categorized as benign or malignant using a statistical algorithm and the results will be compared with the frozen and permanent section results.

|Official Title:||A Pilot Study of Intraoperative Margin Assessment Comparing Optical Spectroscopy and Frozen Section Analysis for Ductal Carcinoma In Situ of the Breast|
- The goal of this research is to develop a minimally invasive technology with the capability of rapidly assessing surgical margins for breast cancer patients undergoing breast conserving therapy.
- Two potential benefits from developing this technology are:
- 1. Decreasing operative times by eliminating the need to wait for histologic margin assessment.
- 2 Intraoperative margin assessment will become available for surgeons performing breast conserving therapy in facilities in-house pathologists.
