Wide Field OCT + AI for Positive Margin Rates in Breast Conservation Surgery.
This is a multi-center, randomized, two-arm study designed to measure the effectiveness of the SELENE system in reducing the number of unaddressed positive margins in breast lumpectomy procedures when used in addition to standard intraoperative margin assessment.
- Breast Cancer
- Eligible Ages
- Over 18 Years
- Eligible Genders
- Accepts Healthy Volunteers
- Female - Age 18 years or older - Patients undergoing elective breast conservation surgery for the treatment of Stage 0-III invasive ductal and/or ductal carcinoma in situ - May include subjects treated with neo-adjuvant therapy (endocrine and/or chemotherapeutic), but not required for study inclusion - Ability to understand and the willingness to sign a written informed consent document
- Male - Metastatic cancer (Stage IV) - Lobular carcinoma as primary diagnosis - Previous ipsilateral breast surgery for benign or malignant disease (this includes implants and breast augmentation) - Subjects with multi-centric disease (histologically diagnosed cancer in two different quadrants of the breast), unless resected in a single specimen - Subjects with bilateral disease (diagnosed cancer in both breasts) - Participating in any other investigational margin assessment study which can influence collection of valid data under this study - Use of cryo-assisted localization - Currently lactating - Current pregnancy - Subjects for whom the specimen margins have been destroyed, damaged, or are otherwise not intact prior to imaging (device arm only) imaging
- Study Type
- Intervention Model
- Parallel Assignment
- Intervention Model Description
- Multi-center, randomized, double-arm trial
- Primary Purpose
- Triple (Participant, Care Provider, Investigator)
- Masking Description
- The pathologist at each participating site will be blinded to the study arm to ensure that the pathological assessment is unbiased. Additionally, the subject will be blinded to their randomization until the BREAST-Q questionnaire has been completed.
Standard of Care
|Lumpectomy with usual intraoperative margin assessment||
|Imaging of all margins with investigational device||
- Perimeter Medical Imaging

Optical coherence tomography (OCT) -- the optical analogue of high-frequency ultrasound -- is well suited for operative suite decision making because it offers real-time, high-resolution tissue imaging with a penetration depth up to 2 mm. The 2 mm depth of penetration is sufficient to accommodate the current national US (and international) guidelines which state that following resection there should be no tumor "on ink" for invasive cancer and not less than a 2 mm margin for DCIS in the absence of invasive disease. Recently, automated image analysis has demonstrated the potential to both improve diagnostic accuracy and reduce overall assessment time. OCT combined with deep learning algorithms has the potential to aid surgeons in identifying regions of interest on scanned samples, enabling them to make key decisions on margin status intraoperatively.
