Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
During surgery ICG fluorescence using a near-infrared imager will be performed at the time of and immediately following primary tumor resection. The imager will evaluate the primary tumor to ensure appropriate tumor fluorescence. Once the primary resection is complete and the surgeon believes that he/she has achieved negative or planned positive margins, fluorescence measurements of the tumor bed will be performed. If areas of positive signal remain, these areas will be resected if possible and sent to pathology for histologic evaluation. It will be recorded if the surgeon perceived negative margins but the device detected positive margins.
Tumor specimens and residual fluorescence positive samples will be evaluated using fresh frozen and permanent histology. Permanent samples will be evaluated for tumor and local fluorescence using confocal microscopy with an ICG cube. Positive fluorescence signal and its correspondence with neoplasm will be noted, a will tumor that does not fluoresce.
Tissue being removed is 1-2 mm from non-structurally important tissue that either has or does not have signal positivity for additional pathologic assessment. It should have no impact on patient outcome, does not represent intervention on sensitive areas (such as neurovascular structures), and can further be used as potential margin around the tumor.

ICG Dye and use of SPY-PHI Imaging
ICG will be administered in the pre-operative unit via IV injection at the time that they present to the pre-operative unit, which is approximately 4 hours before surgery. ICG Angiography (SPY PHI) will be performed to detect any residual signal
Indocyanine green
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.
