#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.

#4613 Correlation of serum cytokeratin 18, ferritin, cancer antigen 125, and beta-2 microglobulin with tumour grade and stage in pancreatic neuroendocrine tumours

Introduction: Pancreatic neuroendocrine neoplasms (PNENs) remain challenging to diagnose, with limited reliable serum biomarkers available for early detection and prognostication.

#4430 Long-term prognosis of parenchyma-sparing vs. oncologic resections for distal pancreatic non-functional neuroendocrine tumours ≤ 3cm: A real-world data study (CSPAC-NEN-5)

Introduction: Studies show that parenchyma-sparing resections (PSR) for small, non-functional pancreatic neuroendocrine tumours (NF-pNETs) provide long-term outcomes similar to oncologic resections (OR). However, these studies have not fully considered location-based differences in surgical approach and lymphatic drainage.
