#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.

#4570 Diagnosis of carcinoid heart disease continues to be late delayed

Introduction: Carcinoid heart disease (CHD) is a serious complication of neuroendocrine tumours. It affects patients with carcinoid syndrome and results from fibrotic deposits on the heart valves. It significantly impacts patient prognosis.

#4465 RET Lys666Asn has low MEN2-related tumours penetrance but may be associated with pheochromocytoma

Introduction: Multiple Endocrine Neoplasia type 2 (MEN2) is caused by germline pathogenic variants (PVs) in the RET proto-oncogene, leading to medullary thyroid carcinoma (MTC), pheochromocytoma, and primary hyperparathyroidism (PHPT). RET c.1998G>C, p.Lys666Asn is a rare PV, with 33 cases described thus far, and is associated with low penetrance of MEN2-related tumours, but its clinical significance remains incompletely understood.

#4352 What can a reference centre offer to patients? Evolution of first visits for neuroendocrine and endocrine tumours and its relation to clinical trials availability.

Introduction: Endocrine and neuroendocrine neoplasia (NEN), which include gastroenteropancreatic neuroendocrine tumours, thyroid cancer and adrenal carcinoma, have a low incidence, making their diagnosis and treatment difficult. Due to this complexity, patients should be managed at specialised centres; however, the lack of official referral networks complicates the concentration of cases.

#4311 Characterisation of patients diagnosed with metastatic head and neck paraganglioma treated at an oncology referral institution in Colombia

Introduction: Head and neck paragangliomas (HNPGL) are rare tumours. Multiple risk factors associated with the risk of metastasis have been described, although much of the available information corresponds to the group of Pheochromocytoma and Paragangliomas, not necessarily extrapolatable to metastatic HNPGLs.
