#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.

#4074 Clinical, genetic and histopathological characterisation of patients with multiple endocrine neoplasia type 1 in two high complexity hospitals in Medellín, Colombia

Introduction: Limited observational data exist regarding the characterization of patients with Multiple Endocrine Neoplasia Type 1 (MEN-1) in Latin America, particularly in Colombia. This scarcity has led to a reliance on studies that may not precisely depict the actual behaviour of the disease within the population.

#3972 Machine-learning identified optimised classification models for the diagnosis of typical and atypical lung carcinoids based on the genomic variance

Introduction: The current diagnosis of lung typical carcinoids (TCs) and atypical carcinoids (ACs) can be ambiguous for small biopsies containing limited tissues.

#3944 Compare the optimal TNM staging of resectable functional and non-functional pancreatic neuroendocrine tumors

Introduction: At present, the European Neuroendocrine Tumor Society (ENETS) and the American Joint Committee on Cancer (AJCC) are two main tumor TNM staging systems. However, the ENETS and AJCC TNM staging systems are different in some aspects when applied to p-NETs.
