#4611 Management strategies and outcomes for type 1 gastric neuroendocrine tumours measuring > 1cm in diameter

Introduction: Although type 1 gastric neuroendocrine tumours (T1-gNETs) are usually considered indolent diseases, the management and the outcome of tumours >1cm remain not well established.

#4561 Prognostic value of pre-therapeutic and interim SSTR PET in patients with GI-NET receiving peptide receptor radionuclide therapy

Introduction: Baseline and interim (after 2 cycles) somatostatin receptor (SSTR)-directed PET/CTs are essential in patients with gastrointestinal neuroendocrine tumours (GI-NET) undergoing peptide radioreceptor therapy (PRRT).

#4553 The efficacy of “rechallenge” peptide receptor radionuclide therapy (PRRT) may be inferior to that of the initial PRRT, while the safety profile remains comparable

Introduction: Data on efficacy and adverse events of re-challenge PRRT (re-PRRT) for patients with gastrointestinal neuroendocrine tumours (GI-NETs) are limited.

#4515 Prognostic factors for survival in patients with metastatic small intestinal neuroendocrine tumours undergoing primary tumour resection

Introduction: Although guidelines recommend primary tumour resection in metastatic small intestinal neuroendocrine tumours (SI-NETs) to manage symptoms and complications, the survival benefit and optimal surgical approach remain unclear.

#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.
