#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.

#4639 Prevalence and characteristics of incidental NET of the Meckel’s diverticula: Retrospective cohort study at a tertiary centre

Introduction: Meckel’s diverticulum is a rare finding in adults but can harbour malignancies such as leiomyosarcoma or neuroendocrine tumours (NET). The clinical presentation and tumour characteristics, including grading, have shown high variability in recent studies for NET.

#4599 Endosonography guided coloenterostomy for management of malignant small bowel ileus

Introduction: Small-bowel ileus (SBI) is often decisive for the prognosis in midgut neuroendocrine tumours (NET) and other peritoneally metastasised neoplasias. Conventional procedures of palliative care deliver unsatisfying results.

#4567 Malignant pheochromocytoma with late distant metastases and secondary hypercalcaemia

Introduction: Pheochromocytoma is a rare neuroendocrine tumour of the adrenal medulla. Malignant variants occur with a very low frequency and can be diagnosed only after the spread of distant metastasis.

#4541 Prognosis analysis of metastatic rectal neuroendocrine tumour: Liver-directed trans arterial embolisation may play a pivotal role

Introduction: Rectal neuroendocrine tumour (rNET) is prone to metastasis, and distant metastasis is associated with worse prognosis. However, factors influencing the prognosis of metastatic rNET and the recommended treatments remain controversial.
