#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.

#4566 Predictive value of high-risk histopathological- and molecular criteria for lymph node metastasis in appendiceal neuroendocrine tumours

Introduction: Appendiceal neuroendocrine tumours (aNET) are rare neoplasms for which consensus is needed for follow-up and additional treatment. To unravel the factors behind aNET which showed lymph node metastasis (LNM) in additional right hemicolectomy (RH), we evaluated high-risk histopathological parameters in aNETs and studied molecular parameters.

#4455 Multicentric ENETS morphological and molecular appraisal of high-grade gastroenteropancreatic neuroendocrine neoplasms (HG-GEP-NEN): Distinguishing NET G3 from NEC

Introduction: HG-GEP-NEN are classified into neuroendocrine tumours grade 3 (NET G3) and neuroendocrine carcinomas (NEC). This distinction is crucial as it affects patient prognosis and treatments but can be challenging.

#4447 Efficacy and safety analysis of XELOX plus bevacizumab in the treatment of metastatic NETs

Introduction: For patients with advanced NETs, standardised treatment protocols based on guideline consensus form the foundation, yet individualised interpretation and flexible application of these guidelines are essential.

Introduction: SDHB pathogenic variants predispose to aggressive and metastatic paragangliomas (mPGLs). International consensus recommends temozolomide treatment (low-grade evidence). Capecitabine and temozolomide (CAPTEM) has shown advantage over temozolomide in the treatment of neuroendocrine tumours (NETs). Evidence for its use in mPGLs remains scarce.
