#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.

#4203 The diagnostic role of DWI-MRI for liver metastases of neuroendocrine neoplasms (NENs) in comparison with the functional imaging

Introduction: A combination of morphological and functional imaging plays a crucial role for diagnosis, staging and therapeutic decision for neuroendocrine neoplasms (NENs). Diffusion-weighted imaging (DWI) magnetic resonance imaging (MRI) is emerging as a key imaging technique in the NEN field.

#3857 The use of quantitative contrast-enhanced endoscopic ultrasound in the evaluation of pancreatic neuroendocrine tumors – Can we move from quality to quantity? A proof-of-concept study

Introduction: Contrast-enhanced EUS (CE-EUS) is a helpful tool for the diagnosis of pancreatic focal lesions, as pancreatic cancer (PC) and pancreatic neuroendocrine tumor (pNEN). The enhancement of the lesion after contrast medium injection is usually assessed qualitatively and arbitrarily by the endosonographer. Dedicated software has recently been developed to obtain an unbiased quantitative assessment using perfusion parameters.

#3777 The value of the Patient Reported Outcomes Common Terminology Criteria for Adverse Events (PRO-CTCAE) in patients with neuroendocrine tumors (NET) treated with 177Lutetium-DOTATATE (177Lu)

Introduction: The correlation between clinical benefit and toxicity is an unmet need in daily clinical practice. PRO-CTCAE is a questionnaire that allows subjective and detailed symptom reporting directly from patients. This prospective, multicentre study will apply PRO-CTCAE in a cohort of consecutive adult patients with metastatic NET on treatment with 177Lu.
