Ina parallel study, a NIR-labeled construct of the anti-VEGFR antibodybevazucimab was administered intravenously to 20 patients with primaryinvasive breast cancer and followed by fluorescence-guided surgery,where all but one tumor showed specific uptake (NCT02583568).53 These studies using NIR analogues of commercialantibodies will accelerate the efficient delineation of tumor marginsusing intraoperative imaging. Here, KDR is linked to neoplasm.
