#4610 The last 10 years – Single centre experience of gastrointestinal NEN

Introduction: Neuroendocrine neoplasms (NEN) are rare and heterogeneous, comprising 2% of all malignancies, with progressively increasing incidence. Most arise sporadically and the most frequent primary sites are gastrointestinal and lung.

#4598 I ain’t missing you at all – Vanishing extra-abdominal small intestinal neuroendocrine carcinoma metastasis

Introduction: Small intestinal neuroendocrine neoplasms (siNEN) are the most common small bowel malignancy. Almost 50% present with distant metastasis.

#4497 Complex management of a long-term gastrinoma survivor with multimodal treatment approaches

Introduction: The prognosis of pancreatic gastrinomas is influenced by tumour burden, extent of metastasis, and treatment response, with 5-year survival rates ranging from 20% to 40%. Treatment for well-differentiated tumours typically include locoregional therapies, long-acting somatostatin analogues, molecular targeted agents, radionuclides, and chemotherapy.

#4253 New insight in the environment immunephenotyping of gastroenteropancreatic neuroendocrine neoplasms: CD 90 expression

Introduction: Neuroendocrine neoplasms (NEN) represent a particular model of host-tumor interaction. CD90 (Thy-1) is a glycoprotein involved in cell–cell/cell–matrix interactions and is associated to stem phenotype and metastatic potential.
