#4398 The role of chromogranin A as a biomarker in neuroendocrine tumours: Diagnostic and prognostic implications

Introduction: Chromogranin A (CgA) is a widely used serum biomarker for neuroendocrine tumours (NETs), reflecting tumour burden and secretory activity. Despite its clinical utility, the diagnostic sensitivity and prognostic value of CgA remain a subject of debate, especially given its potential for false positives and its variation across different NET subtypes.

#4393 Surufatinib plus trans arterial embolisation (TAE) vs. surufatinib monotherapy in neuroendocrine tumour with liver metastasis: Updated results from the prospective, randomised, controlled trial

Introduction: The liver is the main metastasis site for NETs. Surufatinib (SUR), an oral TKI, is standard therapy for advanced NETs. TAE is the primary local intervention for unresectable hepatic NETs.

#4374 Efficacy and safety of immunotherapy combined with antiangiogenesis agents and temozolomide in neuroendocrine carcinoma

#4312 Developing innovative, genetically modified, proliferation-regulated patient-derived models representing human well-differentiated GEP-NETs for drug screening

Introduction: The slow-growing nature of gastroenteropancreatic neuroendocrine tumours (GEP-NETs) has limited the development of clinically relevant models, hindering the discovery in the field.

#4058 Carcinoid syndrome caused by pulmonary neuroendocrine tumor liver metastases: A case report

Introduction: Neuroendocrine tumors (NETs) comprise a heterogeneous groups of maliganancies that arise from neuroencrine cells throughout the body and most commonly originate from the small intestine, lung,and rectum. Pulmonary NETs originate from pulmonary neuroendocrine cells that occur as individual cells or small pulmonary neuroendocrine cell. Although carcinoid tumors are considered low or intermediate-grade tumors, they metastasize to regional lymph nodes and distant organs, and the most common sites metastases are the liver and bone.
