#4610 The last 10 years – Single centre experience of gastrointestinal NEN

Introduction: Neuroendocrine neoplasms (NEN) are rare and heterogeneous, comprising 2% of all malignancies, with progressively increasing incidence. Most arise sporadically and the most frequent primary sites are gastrointestinal and lung.

#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.

#4551 Characterisation and management of neuroendocrine tumours: Findings from a prospective study in Algeria

Introduction: Gastrointestinal neuroendocrine tumours are characterised by varied clinical presentations and behaviours. Their increasing incidence highlights the need for better understanding and management strategies.

#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.
