#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.

#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.

#4001 Sex differences in survival of neuroendocrine neoplasms (NENs): Comparative study of patients from National Cancer Registration and Analysis Service (NCRAS, UK) and Surveillance, Epidemiology, and End Results (SEER, US) databases

Introduction: It has been reported that sex is an important predictor of survival of NEN patients using data from the UK NCRAS database. The same statistical methods have not been applied to US SEER data.

#4000 Prediction of survival for patients with neuroendocrine neoplasms (NENs) using multivariable cox regression and survival nomograms: Data from National Cancer Registration and Analysis Service (NCRAS, UK) Database

Introduction: Multiple nomograms for predicting survival of NENs from surveillance, epidemiology, and end results (SEER) database have been published. To the best of our knowledge, no survival nomogram has been published from NCRAS database
