#4134 Assessment of the current and emerging criteria for the histopathological classification of lung neuroendocrine tumors in the lungNENomics project

Introduction: The lungNENomics project analysed 300 lung neuroendocrine tumors (NETs), of which 259 cases were pathologically reviewed by six expert pathologists.

#4086 Prognostic significance of metabolomics clusters in extra-pancreatic NETs: Lung NET sub-analysis

Introduction: Metabolic flexibility is one of the key hallmarks of cancer and metabolites are the final products of this adaptation, reflecting the aberrant changes that support cancer cells proliferation and survival. In a previous metabolomics study carried out by our group, multiplatform untargeted metabolomic profiling (GC-MS, CE-MS and LC-MS) performed on plasma samples from 77 advanced G1-2 extra-pancreatic NET patients demonstrated that these patients have a distinct metabolomic profile, and identified methionine, porphyrin and tryptophan metabolism as the most relevant dysregulated pathways associated with the prognosis of NETs. Furthermore, a 3-metabolite signature was able to stratify patients in 3 distinct prognostic clusters, with cluster 3 associated with the best prognosis.

#4015 Responses to Cabozantinib plus Atezolizumab in a wide population of advanced and progressive neuroendocrine neoplasms (NENs): A prospective multi-cohort basket phase II Trial (CABATEN / GETNE-T1914)

Introduction: Angiogenesis plays a key role in development and progression of NENs and synergism has been observed when combined with immune-checkpoint inhibitors in other tumors.
