Abstract
BackgroundSurgical management remains the cornerstone in the management of gastro-entero-pancreatic neuroendocrine tumors (GEP-NETs), yet surgical indications and procedures are often inconsistent. To inform the development of a research agenda to strengthen the evidence in NETs surgical care, we conducted a scoping review to map the existing literature on surgery for gastro-entero-pancreatic (GEP) NETs.Materials and MethodsThe scoping review was conducted following the expanded framework of Arksey and O'Malley. A literature search was run on MEDLINE, Embase, and Scopus in October 2024 for studies published since 2000 reporting on any surgical intervention, performed under general or loco-regional anesthesia on adults with GEP-NETs at any stage.ResultsAmong the 10,000 studies screened, 260 were included.
