#4456 Characteristics and clinical outcomes after endoscopic or surgical resection of localised sporadic type III gastric NETs: A national study from the French Group of Endocrine Tumors and ENDOCAN-RENATEN network

Introduction: Type III gastric neuroendocrine tumours (gNETs) are rare indolent tumours with increasing incidence. Endoscopic resection has recently been described to be a safe strategy to remove small, localised type III gNETs.

#4446 Uncommon ophthalmic presentation of a small bowel neuroendocrine tumour: Case report

Introduction: Neuroendocrine tumours (NETs), including carcinoid tumours, are slow-growing neoplasms commonly originating in the gastrointestinal tract or bronchus, but they can also arise in other sites. Due to their indolent nature, the majority of NETs are diagnosed at an advanced stage, typically to the lymph nodes, liver, or bones.

#4391 Clinicopathologic characteristics, therapy and outcomes of gastroenteropancreatic neuroendocrine tumours: A single-centre experience

Introduction: Gastroenteropancreatic neuroendocrine tumours (GEP-NETs) are tumours derived from neuroendocrine cells that can occur anywhere along the gastrointestinal tract and comprise a heterogeneous family of neoplasms with a wide and complex spectrum of clinical behaviour.

#3401 Characterising aggressive pulmonary carcinoids through integrative omics analysis

Introduction: Atypical carcinoids, and our recently identified supra-carcinoids (Alcala et al. 2019) belong to the pulmonary carcinoid (PCA) group of low grade lung neuroendocrine tumors. Little is known about the underlying biology of these tumors, nor why some patients are prone to metastatic disease and tumor recurrence. To date, molecular analysis of these tumors has been limited, particularly with regard to whole-genome sequencing (WGS).
