#4667 Clinical outcomes in patients with typical (TC) and atypical bronchial carcinoids (AC): A 15-year retrospective study from an ENETS Center of Excellence

Introduction: Bronchial neuroendocrine neoplasms (NENs) can be subdivided into TCs, ACs and neuroendocrine carcinomas (NECs). Although a few studies have explored treatment approaches and oncological outcomes, most focus on surgical cohorts, small sample sizes, or mixed groups including TC, AC, and NECs. Real-life cohort data are lacking.

#4661 Comparison of preoperative chemotherapy and radio ligand therapy on prognosis after surgical resection for locally advanced or hepatic metastatic pancreatic neuroendocrine tumours

Introduction: The role of preoperative treatments in improving the rate of radical resection and survival of either locally advanced (LA) or hepatic metastatic (HM) pancreatic neuroendocrine tumours (panNETs) is unclear.

#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.

#4652 Clinical response to somatostatin analogues in patients with DIPNECH: Findings from a new longitudinal registry

Introduction: Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH) often presents with symptoms of cough and dyspnoea. DIPNECH remains understudied, and response to somatostatin analogues (SSAs) has been reported in a few small series.

#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.
