#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.

#4637 Non-functional retroperitoneal paraganglioma in a young patient: A case report

Introduction: Paragangliomas are neuroendocrine tumours arising in the parasympathetic nervous system, outside the adrenal gland. Retroperitoneal location is extremely rare. Non-functional paragangliomas often represent a diagnostic challenge.

#4620 Impact of the extent of surgical resection on the development of post-operative diabetes in patients undergoing distal pancreatectomy for non-functioning pancreatic neuroendocrine tumours (NF-PanNET)

Introduction: Pancreatic neuroendocrine tumours (PanNETs) are often indolent neoplasms. Surgery is the primary curative approach for localised non-functioning (NF) PanNETs, but it poses a risk of long-term complications, such as diabetes, impacting quality of life.

#4549 Alpha-Fetoprotein as a valuable biomarker in neuroendocrine tumours

Introduction: Neuroendocrine tumours (NETs) are a rare group of tumours that pose a significant diagnostic, therapeutic, and prognostic challenge. This complexity arises from the diversity and heterogeneity of these neoplasms, as well as from the limitations of commonly used biomarkers in clinical practice. Alpha-fetoprotein (AFP) is a fetal protein widely used primarily for congenital defects in prenatal diagnostics and in certain malignancies in adults.
