Study of PRRT in Metastatic, World Health Organization (WHO) Grade 1 or 2, SSTR Positive, GEP-NET Who Are Candidates for Cytoreductive Surgery
Pilot Phase 1 Study of Perioperative Peptide Receptor Radionuclide Therapy (PRRT) in Metastatic, WHO Grade 1 or 2, SSTR Positive, Gastroenteropancreatic Neuroendocrine Tumors Who Are Candidates for Cytoreductive Surgery
Stanford University

INTERVENTIONAL
Conditions
Summary
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.
Eligibility
Inclusion Criteria9
