Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Patients with operable breast cancer treated with chemotherapy and eligible for SLNB will be included in the study. During surgery, ICG will be injected and used to identify fluorescent sentinel nodes using a hand-held imaging camera; radiotracer and blue dye will also be used as per standard protocols. Intraoperative and clinicopathologic outcomes such as complications, characteristics of nodes, false negative rates and feasibility will be assessed. Patients will be asked to complete standardized patient reported outcome questionnaires (Breast-Q, FACT-B+4, VAS) to define the patient experience with this novel technique.

ICG-SLNB
This is a prospective within-patient clinical study to assess the accuracy of ICG SLNB compared to standard dual-tracer SLNB in breast cancer patients treated with neoadjuvant chemotherapy. For SLNB, triple localization of the sentinel lymph nodes using blue dye, Tc-99m and ICG will be utilized in each patient.
ICG guided sentinel lymph node biopsy
During sentinel lymph node biopsy the surgeon will inject a volume of 0.1ml divided into 2 doses (0.05ml each) of 2.5mg/mL ICG into the periareolar dermis of the involved breast. Technetium and blue dye will also be administered as per standard of care. The surgeon will assess the axilla with the the SPY-PHI near infrared imaging system to identify and remove ICG-fluorescent nodes; Any other sentinel lymph nodes identified will also be removed as per standard of care. If there is no progression of ICG towards the axilla, or if no ICG sentinel lymph node can be identified, an alternate injection technique involving peritumoural injection at 2-3 locations near the cancer site in the subcutaneous or dermal space of 0.05ml will be utilized.
