#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.

#4382 Sensitivity of endoscopic ultrasound in detecting small gastrointestinal neuroendocrine tumours

Introduction: Small gastrointestinal neuroendocrine tumours (GI-NETs) are often difficult to detect using conventional imaging modalities, leading to delayed diagnosis and suboptimal treatment outcomes. Endoscopic ultrasound (EUS) has emerged as a promising tool for the early detection and precise localisation of these tumours. However, its sensitivity in identifying small lesions remains to be thoroughly evaluated.

#4292 Predictors based on the radiologic characteristics for aggressiveness of small (＜20 mm) non-functioning pancreatic neuroendocrine tumours

Introduction: The management of small non-functioning PNETs remains controversial due to their heterogeneity. Results from some retrospective surgical reports found that a subset of small NF-PNETs may show aggressive behaviour, for which surgical resection is recommended.

#4045 Radio-guided surgery with a new generation β-probe for radiolabelled somatostatin analogue, in patients with small intestinal neuroendocrine tumors – A Phase II surgical trial

Introduction: Radio-guided surgery (RGS) proved to be promising in neuroendocrine tumors (NETs). Previous studies showed high sensitivity but low specificity using gamma probes to detect radiation emitted by radio-labelled somatostatin analogues.

#3976 Radiologic tumor border status can further stratify patients with pancreatic neuroendocrine tumor

Introduction: Recently, pattern-based classifications of the tumor border of pancreatic neuroendocrine tumor (PanNET) have been attempted by independent groups for patient stratification, which are only available in the post-operative setting.
