Intraoperative Tumor Margin Identification With ICG Dye Imaging

The SPY PHI and its dye Indocyanine Green dye (ICG) is a non-invasive device that is connected to a light source tower that is already available in the hospital in the operating room under Gynecology and Obstetrics Equipment. This is a special light source lamp that allows to test for vascularity in the soft tissues intraoperatively. Previous research in animal models proved the concept that the increased vascularity in tumors can be used to use this device to improve intraoperative assessment of tumor margins during resection. Our study will help to establish a correlation between activity with the dye and histological findings. This information has the potential to help sarcoma patients by avoiding staged surgeries, decreasing hospitalization times, and decreasing the likelihood of local recurrence by improving margin quality.
