Trial ID: NCT04609592

Purpose

The purpose of this study is to learn about the feasibility and safety of using Peptide Receptor Radionuclide Therapy (PRRT) before and after surgical removal of a tumor. PRRT treatment is based on the administration of a radioactive product, 177-Lu DOTA-0-Tyr3-Octreotate (Lutathera®) and its use before and after surgery is thought to increase the overall survival benefit for patients with SSTR-positive gastroenteropancreatic neuroendocrine tumors GEP-NETs.
