This is a single-arm, prospective, study of an optical imaging device on approximately twenty (20) subjects undergoing lumpectomies at one study site. In vivo and ex vivo imaging will be performed on study subjects with results being compared to final pathology.
The sensitivity and specificity of Optical Coherence Tomography to identify whether or not tumor can be identified ex vivo on breast cancer specimens as compared to post-surgical histology conclusions.
time frame: One week after surgery
Female participants at least 18 years old.
Inclusion Criteria: 1. Women 18 years of age or older 2. Signed ICF 3. Women who have been histologically diagnosed with invasive ductal carcinoma or invasive lobular carcinoma of the breast prior to surgery 4. Planning breast preservation 5. Patients undergoing lumpectomy (partial mastectomy) procedure Exclusion Criteria: 1. Multicentric disease (histologically diagnosed cancer in two different quadrants of the breast) 2. Neoadjuvant systemic therapy 3. All T4 tumors 4. Previous radiation in the operated breast 5. Prior surgical procedure in the same quadrant 6. Implants in the operated breast 7. Pregnancy 8. Lactation 9. Participating in any other investigational study for either drug or device which can influence collection of valid data under this study
|Official title||Real Time Optical Coherence Tomography (OCT) of Human Tissue|
|Description||This study is a single-center, prospective, two-part open label study of an optical imaging device on approximately twenty (20) subjects at one (1) study site. Patients scheduled to undergo a lumpectomy will be recruited by the clinical investigators at the investigational site in accordance with the inclusion and exclusion criteria. The study period per subject is the time it takes to assess the in vivo and ex vivo breast tissue samples using the study device during their lumpectomy. All specimens will be marked with India ink and undergo standard post-operative histology, and digital histology images corresponding to the inked locations will be obtained. The images and the matched digitized post-operative histology images will then be randomized and read by a blinded, independent pathologist. Sensitivity and specificity will be calculated.|
