#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.

#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.

#4441 Gastric neuroendocrine neoplasms in younger patients: A retrospective single-centre study

Introduction: Gastric neuroendocrine neoplasms (gNENs) are rare neoplasms arising from stomach enterochromaffin-like (ECL) cells. Type I gNENs are the most common type, typically indolent and arising in the context of chronic atrophic gastritis (CAG). While type I gNENs are generally diagnosed in pts over 50, their occurrence in younger pts raises concern about the onset of CAG-related complications at an earlier age, potentially affecting tumour growth and clinical outcomes. Young-oriented studies on type I gNETs are still lacking in literature.

#4419 Real-world outcomes in patients with gastroenteropancreatic neuroendocrine neoplasms at a cancer centre in a middle-income country

Introduction: Gastroenteropancreatic (GEP) neuroendocrine neoplasms (NENs) are rare tumours that are increasing in prevalence. However, the epidemiology of GEP-NENs in Latin America is not well understood.

#4356 Assessment of medium- and long-term side effects of Lu-177 treatment in patients with neuroendocrine tumours

Introduction: PRRT with Lu-177 has advanced the treatment of neuroendocrine tumours (NETs), adding a valuable tool against them. This study aims to assess its long-term impact, especially on the most radio-exposed organs—kidneys and bone marrow—and the reproducibility of in vivo clinical trial results (PFS).
