#3771 Epidemiological profile and survival of neuroendocrine tumors of the ampulla of Vater

Introduction: Duodenal neuroendocrine tumors are rare, they represent nearly 2% of digestive NETs. Their incidence is increasing due to better detection. The diagnosis is often late because of the non-specific symptomatology of the tumor. The 5-year survival of duodenal NETs is 68% when the tumor is diagnosed at an early stage.

#3503 Neuroendocrine neoplasms of the biliary tract: A single ENETS Centre of Excellence case series

Introduction: Neuroendocrine neoplasms (NENs) of the biliary tract are rare. They represent approximately 2% of all NENs. They can arise from the gallbladder, extra-hepatic biliary tract (EHBD) and ampulla of Vater (AoV).

#3215 Mixed neuroendocrine non-neuroendocrine neoplasm of the ampulla of Vater: Case Report

Introduction: Mixed neuroendocrine non-neuroendocrine neoplasm (MiNEN) is defined as a tumor composed of both neuroendocrine and non-neuroendocrine components. MiNEN of the ampulla of Vater is a rare neuroendocrine tumor of the gastrointestinal tract.

#2738 Patient-Derived Organoid Models of Human Neuroendocrine Carcinoma

Introduction: Gastroenteropancreatic neuroendocrine carcinoma (GEP-NEC) is a poorly understood disease with limited treatment options. Due to its low incidence and wide tissue distribution few representative preclinical models are available
