#4523 Preoperative evaluation of tumour border using radiomics and its surgical guidance in pancreatic neuroendocrine tumours

Introduction: Pancreatic neuroendocrine tumours are a heterogeneous group of tumours originating from peptidergic neurons and neuroendocrine cells with variable survival outcomes. Surgical resection is the mainstay of treatment. However, there is an ambiguous insight into the real need to execute the standard surgery in small pancreatic neuroendocrine tumours. The tumour border is a powerful determinant of survival prognosis in many tumours and is often used as a safety guarantee for parenchyma-sparing resections. However, there are no studies evaluating tumour border with or without preoperative imaging in pNETs.

#4457 Primary mixed hepatocellular carcinoma-neuroendocrine carcinoma: A case report

Introduction: Mixed epithelial neoplasms (MiNENs) are characterised by the coexistence of neuroendocrine and non-neuroendocrine components within a single tumour, each discernible histologically and immunohistochemically, with a minimum tumour proportion of 30%. Primary hepatic MiNENs are exceedingly rare entities.

#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.

#4377 Characteristics of endoscopic ultrasonography in patients with gastrointestinal and pancreatic neuroendocrine tumours

Introduction: Neuroendocrine tumours are most commonly found in the gastrointestinal tract. With the development of endoscopic ultrasound, the incidence of GEP-NENs has increased year by year.
