Fluorescence-guided surgery offers strong promise for improving surgical resection of soft-tissue sarcomas (STSs). However, our preclinical and clinical work shows no single reporter fluoresces all areas of the tumor, thereby compromising our ability to reliably detect residual cancer left behind after initial resection. In this work, we develop an innovative strategy for identifying residual tumor following sarcoma removal by optimizing tumor distribution and contrast using multiple near-infrared fluorophore reporters, all with similar emission wavelengths, simultaneously in complementary combinations and test it in a murine xenograft model of STS.
