Abstract
Abstract Intraoperative delineation of the tumor with minimal negative margins is the holy grail of lung cancer surgery. Segmentectomy is a minimal resection surgery required for elderly patients or small sized early-stage lung cancer patients, in which accurate detection of tumor margins with simultaneous identification of the lung intersegment plane is the key to success. However, non-small cell lung cancer is difficult to detect intraoperatively, and the identification of intersegmental plane is challenging during minimal resection surgery. Here, we report dual-channel image-guided lung cancer surgery using renal clearable and physiochemically stable targeted fluorophores to visualize the tumor margins and intersegmental plane separately with different colors but simultaneously: cRGD-ZW800-PEG (800 nm channel) allows for tumor-specific targeting and ZW700-1C (700 nm channel) for discrimination of segmental planes. Armed with the dual-channel imaging, image-guided surgery enables complete tumor resection with minimal negative margins that can reduce the recurrence rate and increase the survival rate of lung cancer patients.
