- Scientific TitleEvaluation of a Clinical Prototype Near-InfraRed Fluorescence (NIRF) Imaging Device for Sentinel Lymph Node (SLN) Detection in Breast Cancer Patients: a Technical Feasibility Study.
- hypothesisThis technical feasibility study hypothesizes that an ICG enhanced near-infrared fluorescence (NIRF) imaging camera enables the detection of the sentinel lymph node (SLN) in breast cancer patients.
- Healt Condition(s) or Problem(s) studiedBreast cancer
- Inclusion criteriaWomen above the age of 21 with biopsy-proven breast cancer, and who are planning to undergo sentinel lymph node mapping for staging and treatment of their disease.

- InterventionsPatients with stage I-II biopsy proven breast cancer who undergo a standard lumpectomy combined with a sentinel lymph node (SLN) procedure, will receive an peritumoural injection with indocyanine green (ICG). Simultaneously with the localization of the SLN by the standard detection procedure (i.e. radioactive colloid detection by a hand-held gamma probe and visual observation of the presence of Patent blue), a NIRF camera system will capture images of the operative field for the detection of the NIRF signal derived from ICG present in the lymphatic vessels and lymph nodes.
- Primary outcomeThe main endpoints of this feasibility study are ergonomics and function of the imaging system. The NIRF imaging system should not interfere with the standard SLN mapping procedure and used safely by the surgeon while detection of ICG takes place. Safely is defined as: no increased risk of infection, no interference with the standard procedure and no excessive prolongation of the operative procedure (i.e. more than 2,5 hours).
- Secondary outcomeThe secondary endpoint of this feasibility study is the number and location of detected sentinel lymph nodes compared to the standard detection of SLNs with the use of patent blue and technetium-99 labeled colloid.

- Brief summaryRationale: This project consists on the realization followed by the clinical validation of a medical instrument dedicated to sentinel lymph nodes identification and localization in the case of breast cancer. An intra-operative near-infrared fluorescence imaging camera will be evaluated for its technical feasibility to detect the sentinel lymph node (SLN) in patients with breast cancer. The sentinel lymph node technique, based on the propagation of cancer cells in the lymphatic system, allows for a better evaluation of tumor staging, prognosis and therapeutic strategy determination. The end-goal of this intra-operative imaging instrument, designed by physicians and physicists, is to improve the detection and efficiency of the technique significantly in order to reduce the false negative rate and then the recurrence risk, as well as the operative morbidity. Clinical oncologist surgeons and fundamental physics applied to medical imaging researchers are involved in this project.
