Indocyanine Green (ICG) Guided Tumor Resection
St. Jude Children's Research Hospital
Summary
This is a study to assess the ability of Indocyanine Green (ICG) to identify neoplastic disease. For many pediatric solid tumors, complete resection of the primary site and/or metastatic deposits is critical for achieving a cure. An optimal intra-operative tool to help visualize tumor and its margins would be of benefit. ICG real-time fluorescence imaging is a technique being used increasingly in adults for this purpose. We propose to use it during surgery for pediatric malignancies. All patients with tumors that require localization for resection or biopsy of the tumor and/or metastatic lesions will be eligible. Primary Objective To assess the feasibility of Indocyanine Green (ICG)-mediated near-infrared (NIR) imagery to identify neoplastic disease during the conduct of surgery to resect neoplastic lesions in children and adolescents. NIR imaging will be done at the start of surgery to assess NIR-positivity of the lesion(s) and at the end of surgery to assess completeness of resection. Separate assessments will be made for the following different histologic categories: 1. Osteosarcoma 2. Neuroblastoma 3. Metastatic pulmonary deposits - closed to accrual Exploratory Objectives 1. To compare the ICG uptake by primary vs metastatic site and pre-treated (chemotherapy, radiation, or both) vs non-pre-treated. 2. Assess the sensitivity and specificity of NIR imagery to find additional lesions not identified by standard of care intraoperative inspection and tactile feedback. 3. Assess the sensitivity and specificity of NIR imagery to find additional lesions not identified on preoperative diagnostic imaging. 4. Assess the sensitivity and specificity of NIR imagery for identifying residual disease at the conclusion of a tumor resection. Separate assessments will be made for the following different histologic categories based on their actual enrollment; this includes but is not limited to analyzing multiple arms together: 1. Ewing Sarcoma 2. Rhabdomyosarcoma (RMS) 3. Non-Rhabdomyosarcoma Soft Tissue Sarcoma (NRSTS) 4. Renal tumors 5. Liver tumors, lymphoma, other rare tumors, and nodules of unknown etiology
Description
This trial is a single center open-label study. Patients with a solid tumor or lymphoma who require resection either for therapeutic or diagnostic intent will be included. Indocyanine Green (ICG) is an FDA-approved drug. Prior to surgery, patients will receive a single dose of ICG intravenously. During surgery, after the surgeon identifies the mass through visual (seen with the naked eye) and or tactile methods (palpated), the patient will have his/her tumor field imaged by Iridium system optimized for detection of ICG (EleVision™ IR Platform). The entire procedure will be photo- documented…
