#4656 Development of a 3D patient-derived extracellular matrix hydrogel model of small intestinal neuroendocrine tumour and mesenteric fibrosis

Introduction: The pathogenesis of mesenteric fibrosis in small intestinal neuroendocrine tumours (SI-NETs) is poorly understood, limiting development of effective treatments and biomarkers. A major barrier to research is the lack of disease models.

#4546 Epigenetic exploration of mesenteric fibrosis indicates epigenetic disruption of DAXX is driving metastatic potential in small intestinal neuroendocrine tumours

Introduction: Up to 50% of patients diagnosed with small intestinal neuroendocrine tumours (SI-NETs) are affected by mesenteric fibrosis (MF) which has significant pathological effects and impacts patient mortality.

#4256 Epigenetic prediction of aging and metabolic traits provides insight into tumor biology in multi-focal ileal neuroendocrine tumors

Introduction: Approximately half of small intestinal neuroendocrine tumors (siNETs) are multifocal, and recent investigations into the genetic architecture of these tumors have found that they are not clonal. Due to the low mutational rate and slow growing nature of these small tumors, the ‘timing’ of the development of individual tumors has not been possible.

#2169 Patient and Clinician Perspectives on Symptom Priorities Across the Spectrum of Neuroendocrine Tumors (NETs)

Introduction: NETs are associated with a range of symptoms, and symptom reduction is a common treatment target. Identifying priority symptoms across NETs can help inform clinical trial endpoints.
