FEASIBILITY AND SAFETY OF INDOCYANINE GREEN (ICG) GUIDED SENTINEL LYMPH NODE MAPPING FOR PEDIATRIC SOLID TUMORS - T-LyM (Tumor-Lymph Node Mapping)
The purpose of this study is to assess the feasibility and safety of ICG-guided intraoperative lymphography for detecting sentinel lymph nodes (SLN) in pediatric patients with solid tumors who require retroperitoneal lymph node dissection/sampling.
This trial is a single-site cross-sectional study. The injection of ICG directly into lymphatics draining the primary tumor will take place at the time of operation after the patient is under anesthesia.
Inclusion: Any pediatric patient (under the age of 18 years) being treated at the University of Rochester Medical Center, Department of Surgery; Diagnosed with pediatric solid tumor; Scheduled to undergo lymph node sampling as part of their clinical management.
Exclusion: Patients with extensive prior surgery at the primary site or nodal basin expected to affect the lymphatic drainage; Subjects with a history of iodide allergies; Inability or unwillingness of research participant or parent/legal guardian to give written informed consent; Currently pregnant; Infants under 650 grams.
