#4639 Prevalence and characteristics of incidental NET of the Meckel’s diverticula: Retrospective cohort study at a tertiary centre

Introduction: Meckel’s diverticulum is a rare finding in adults but can harbour malignancies such as leiomyosarcoma or neuroendocrine tumours (NET). The clinical presentation and tumour characteristics, including grading, have shown high variability in recent studies for NET.

#4566 Predictive value of high-risk histopathological- and molecular criteria for lymph node metastasis in appendiceal neuroendocrine tumours

Introduction: Appendiceal neuroendocrine tumours (aNET) are rare neoplasms for which consensus is needed for follow-up and additional treatment. To unravel the factors behind aNET which showed lymph node metastasis (LNM) in additional right hemicolectomy (RH), we evaluated high-risk histopathological parameters in aNETs and studied molecular parameters.

#4496 ATRX, DAXX, and menin immunohistochemistry identify prognostic relevant non-functioning neuroendocrine tumours subgroups

Introduction: Non-functioning pancreatic neuroendocrine tumours (NF-pNETs) are rare tumours with a variable prognosis. Recent studies have identified prognostic subgroups based on ATRX, DAXX and MEN1 mutations along with chromosomal aneuploidies.

#4300 A retrospective comparison of preoperative characteristics and surgical outcomes in small intestine neuroendocrine neoplasms (SiNENs) and small intestine adenocarcinoma

Introduction: SiNENs are complex tumours with unique behaviour. Despite 30 years of progress, limited data and diagnostic challenges hinder understanding, complicating assessment of their biology and outcomes.
