#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.

#4112 Sexual dimorphism in small intestinal NETs: Any association with development of mesenteric metastases?

Introduction: Small-intestinal neuroendocrine tumors (SI-NET) are rising in incidence and complications such as mesenteric and hepatic metastases are associated with increased morbidity and mortality. It has recently been suggested that mesenteric metastases risk increases in women around menopause.

#4041 Mesenteric fibrosis in small intestinal neuroendocrine tumors (SI-NETs): Pathogenesis and therapeutic targets

Introduction: Mesenteric fibrosis (MF) affects up to 50% of small intestine neuroendocrine tumor (SI-NET) patients, causing significant morbidity and mortality. MF pathophysiology is poorly understood, limiting treatment development and biomarker identification.

#3651 Mesenteric fibrosis in small intestinal neuroendocrine tumors (SI-NETs) – Steps towards understanding its pathogenesis

Introduction: Mesenteric fibrosis (MF) occurs in 50% of patients with SI-NETs, causing significant morbidity and mortality. The pathogenesis of MF in SI-NETs is incompletely understood with no biomarkers or radiological criteria to predict long-term complications of SI-NET associated MF.
