#4670 The efficacy of first-line combination therapy with everolimus plus lanreotide for gastroenteropancreatic neuroendocrine tumour with a poor prognostic factor: Updated and subgroup analysis of the phase III study, STARTER-NET (JCOG1901)

Introduction: Everolimus monotherapy provided a limited median progression-free survival (PFS) for gastroenteropancreatic neuroendocrine tumours (GEP-NETs), there remains a necessity for better therapeutic approaches.

#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.

#4650 Whole exome sequencing in pulmonary neuroendocrine neoplasms: Findings from a pilot investigation

Introduction: The molecular landscape of lung neuroendocrine tumours (NETs) is still poorly characterised. Lung NETs main prognostic factors currently include stage, histotype, grade, location, and demographic parameters, but molecular biomarkers are still not available, limiting the possibility for personalised therapeutic strategies.
