#2940 Avelumab in Unresectable/Metastatic, Progressive, Poorly Differentiated, Grade 3 Neuroendocrine Carcinomas (NECs)

Introduction: Poorly differentiated, G3 NECs are associated with poor outcomes and have no effective treatment options apart from cytotoxic chemotherapy.

#2929 Type III Gastric Neuroendocrine Neoplasms: Is Local Excision Sufficient in Selected Cases?

Introduction: As per ENETS Guidelines, patients with type III gastric neuroendocrine neoplasms (t-III g-NEN), need to undergo partial or total gastrectomy. Data for less-extensive resections are limited.

#2760 Management and Outcomes of Duodenal Neuroendocrine Tumours

Introduction: Duodenal NENs (D-NENs) are increasing in incidence often incidentally identified at endoscopy. ENETS guidelines suggest endoscopic resection for duodenal NETs <1cm if not periampullary.

#2711 Gastric Neuroendocrine Neoplasms: Clinical Management and Outcomes in a Cohort of 54 Patients

Introduction: Gastric NENs are increasingly being diagnosed at endoscopy. The majority of these are type 1 gastric NEN. However, around 10-20% can be type 3 or type 4 Gastric NENs.

#2709 Endoscopic Management and Outcomes of Gastro-Duodenal Neuroendocrine Tumours

Introduction: Gastric and duodenal neuroendocrine tumours are increasing in incidence. ENETS guidelines suggest endoscopic resection of type 1 gastric NENs over 10mm and consider endoscopic resection for duodenal NENs. However, the endoscopic techniques are not clearly mandated. There, is evidence to suggest endoscopic mucosal dissection has higher incidence of R0 resections compared with polypectomy or EMR alone.
