#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.

#4439 Survival of 10,418 lung neuroendocrine tumours after surgical resection: Who needs follow-up and for how long?

Introduction: Surgical resection is the primary treatment for lung neuroendocrine tumours (NETs). The optimal follow-up period is debated in these patients.

#4282 A first-in-human phase I trial with antibody drug conjugate ADCT-701 in neuroendocrine tumours and carcinomas

Introduction: Neuroendocrine neoplasms (NENs) consist of neuroendocrine tumours and neuroendocrine carcinomas, which are rare malignancies found in various anatomical sites, including the gastrointestinal tract, pancreatic islets, lungs, and adrenal glands. Poorly differentiated NECs are classified as high-grade carcinomas that bear resemblance to small-cell lung cancer; however, these patients experience a high risk of relapse and demonstrate a limited response to additional systemic therapies. Adrenocortical carcinoma (ACC) is another rare cancer and currently, no targeted therapies have demonstrated significant effectiveness for this condition. Preclinical investigations have indicated that Delta-like non-canonical notch ligand 1 (DLK1) is expressed in various neuroendocrine neoplasms, including ACC, SCLC, neuroblastoma, pheochromocytoma, and paraganglioma.

#4016 Factors influencing emergency admissions in patients with neuroendocrine neoplasms (NEN) in England 2016-2017

Introduction: Diagnostic delays in neuroendocrine neoplasms (NEN) are common, with NENs presenting as emergencies in a subset of cases. Emergency presentations (EP) may cause poor outcomes and should be avoided.
