#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.

#4655 A novel nonpeptide drug conjugate (NDC) for the treatment of somatostatin receptor 2-expressing tumours

Introduction: Somatostatin receptor 2 (SST2) is an established target for the treatment of NETs and potentially other solid tumours.

#4647 Crosstalk between cancer-associated fibroblasts and small intestinal neuroendocrine tumour cells in a 3D spheroid model

Introduction: At diagnosis, over 50% of small intestinal neuroendocrine tumours (SI-NETs) have metastasised to the mesentery where they often induce extensive fibrosis. Recent studies highlight the crucial interaction between SI-NET cells and cancer-associated fibroblasts (CAFs) in the pathogenesis of mesenteric fibrosis (MF).

#4534 Development of new 3D in vitro models for pancreatic neuroendocrine tumours (PanNETs)

Introduction: Current PanNET in vitro models struggle to accurately replicate the tumour’s biology and microenvironment, limiting understanding of the mechanisms underlying PanNET behaviour and drugs response.

#4531 The role of metabolism in neuroendocrine tumour cell models and patients

Introduction: It is recognised that the adipose tissue plays a major role in cancer through a metabolic coupling that supports tumour cell growth. Recent evidence suggests that altered metabolic pathways drive the development and influence the clinical outcomes of gastroenteropancreatic neuroendocrine tumours (GEP-NETs).
