#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.

#4597 FIT-NETs: Assessing the effects of an exercise programme on the physical and emotional well-being of patients with advanced G1-2 NETs of GEP or unknown origin

Introduction: Physical activity programs in solid tumours have shown to improve symptom control and even survival, but their impact on NENs remains unexplored. Advanced disease, systemic therapy, and hormonal secretion in these tumours often lead to muscle wasting and sarcopenia.

#4588 Spatial transcriptomics identifies Wnt signalling in multifocal ileal neuroendocrine tumours

Introduction: Ileal neuroendocrine tumours (i-NETs) often present with multiple primary tumours (>30-40%). Recent studies showed no shared somatic mutations in multiple primary tumours, highlighting the need to examine the tumour microenvironment in tumorigenesis. The Wnt signalling pathway is crucial for organ stem cell regulation. While the Wnt/β-catenin pathway influences prostate and pancreatic NET/Cs, its role in i-NETs remains unclear.

#4585 Short-term observation of liver transplantation combined with multidisciplinary integrated treatment of liver metastases from neuroendocrine tumours beyond the Milan criteria

Introduction: The continuous progress of comprehensive treatment enables neuroendocrine tumour liver metastasis (NENLM) that meets Milan criteria to achieve longer survival without liver transplantation (LT). LT often faces high tumour burden, while comprehensive treatment also brings new opportunities for recurrence.

#4544 Spatial and temporal intratumour heterogeneity of pancreatic neuroendocrine tumours (PanNET)

Introduction: Data derived from the study of intertumour heterogeneity have led to propose that PanNET evolution may start either from beta cells with good prognosis, or from alpha cells with sequential alterations of MDA (MENIN-DAXX/ATRX) leading to more aggressive lesions.
