#4474 Follow-up 68Ga-DOTATATE PET/CT post resection of small bowel neuroendocrine neoplasia

Introduction: Surgery remains the mainstay of treatment for resectable neuroendocrine neoplasms (NENs). Post resection, guidelines suggest a risk-based approach to surveillance, with 3-6 monthly imaging based on tumour biology. However, there is a paucity of data regarding the timing of surveillance imaging for resected well-differentiated NEN.

#4462 Clustering of gastroenteropancreatic neuroendocrine neoplasms (GEP-NEN) using machine learning (ML) and comparison with tumour, node, metastasis (TNM) staging: A population-based study using surveillance, epidemiology, and end results (SEER)

Introduction: TNM 8 is the staging system for GEP-NEN, guiding prognosis and treatment. However, it does not include important prognostic factors such as age, sex, race, and morphology.

#4318 Management of asymptomatic, sporadic, small non-functional pancreatic neuroendocrine tumours: Active surveillance or surgery? A retrospective cohort study in the SEER database

Introduction: Non-functional pancreatic neuroendocrine tumours (NF-PanNETs) exhibit a wide heterogeneity of aggressiveness and optimal management of asymptomatic, sporadic, small PanNETs remains controversial.

#4315 The indolent nature of type 1 gastric neuroendocrine tumours under 1cm: Insights from a dual-centre study

Introduction: Current guidelines primarily recommend endoscopic surveillance for type 1 gastric neuroendocrine tumours (g-NETs) measuring ≤10mm, though these guidelines are largely based on expert consensus rather than strong evidence.
