Evaluation of Intraoperative Tumor Margin Identification With Fluorescent Dye Imaging
Massachusetts General Hospital
Summary
In this research study we want to learn more about the use of indocyanine green (ICG) during bone or soft tissue mass resections. Indocyanine green (ICG) is a type of dye that is used in medical diagnostics. We want to determine if ICG-guided tumor resection is more effective in obtaining negative margins. Lastly, we want to assess traditional oncologic outcomes of local recurrence, time to metastatic disease, and overall and disease specific survival.
Description
If you are present for a preoperative clinic visit the day before your surgery, ICG may be administered via injection. Otherwise, ICG will be administered in the preoperative unit via IV injection at the time of presentation approximately 4 hours before your surgery. You will be monitored during and after ICG dosing. 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 sur…

Inclusion Criteria: * All patients 18 years of age or older who present to Massachusetts General Hospital Department of Orthopaedic Surgery with a benign or malignant bone or soft tissue mass that is consented for surgery during the study period. Exclusion Criteria: * Pregnant or nursing patients * Patients with previously known anaphylaxis to IV contrast or iodine (other allergies may be considered on a case-by-case basis) * Patients in renal failure who are not cleared for ICG administration by their primary physician or oncologist
Interventions
- DrugIndocyanine 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.
