Multi-Omic Characterization and Evolution of Neuroendocrine Neoplasm Organoids
Introduction:
Molecular characterizations of neuroendocrine neoplasm (NENs) have unveiled candidate alterations associated with aggressiveness and suggested that the molecular link between neuroendocrine tumors (NETs) and neuroendocrine carcinomas (NECs) might be subtler than initially thought. For example, we have recently unveiled a new entity of pulmonary carcinoids (supra-carcinoids) with carcinoid-like morphology yet the molecular and clinical features of large cell neuroendocrine carcinoma (LCNEC). Testing hypotheses to explain aggressiveness and the possibility of progression or transition from NET to NEC through the accumulation of genetic anomalies requires in vitro and in vivo experimental models.

Resource Use in Patients with Carcinoid Syndrome: A Retrospective Analysis Using the French Health Insurance National (SNDS) Database
Introduction:
About 20% of patients (pts) with neuroendocrine tumors (NET) suffer from carcinoid syndrome (CS), mainly from ileum and lung NET. Pts with CS experience symptoms such as diarrhea, flushes and cardiac complications. The diarrhea occurs in almost all pts with CS and can be truly debilitating. Therefore, on top of the tumor, the burden of the symptoms further impairs quality of life and is associated with additional costs related to symptom management and pts follow-up.

Aberrant Tryptophan Metabolism in Stromal Cells Is Associated with Mesenteric Fibrosis in Small Intestinal Neuroendocrine Tumours
Introduction:
Increased levels of serotonin secretion are associated with mesenteric fibrosis (MF) in small intestinal neuroendocrine tumors (SI-NETs). However, only a proportion of patients with increased serotonin production will develop mesenteric fibrosis.

Prediction of Symptomatic Mesenteric Mass in Patients with Small Intestinal Neuroendocrine Tumors Using a CT Radiomics Approach
Introduction:
A mesenteric mass surrounded by fibrosis is a hallmark feature of small intestinal neuroendocrine tumors (SI-NETs) that can induce severe abdominal complications. To improve clinical outcome, there is a need for personalized treatment strategies based on accurate prediction of development of abdominal complications.

The PanNENomics Project: A Call for an International Collaborative Effort Built on the Success of the LungNENomics Project
Introduction:
Neuroendocrine tumors are rare understudied diseases at the molecular level, especially those occurring in sites outside the lung and the gastrointestinal track. This lack of knowledge has strong implications for the clinical management of these diseases (Rindi et al. Mad Pathol 2018).
