Analysis of the Proteomics of Serum Circulating Exosomes in Gastro-Entero-Pancreatic Neuroendocrine Neoplasms Abstract #2144

Introduction: Gastro-entero-pancreatic neuroendocrine neoplasms(GEP-NENs) are intractable, heterogeneous tumors, characterized by secreting serotonin metabolites or polypeptide hormones. There are currently little targets for the diagnosis and treatment of GEP-NENs. Serum circulating exosomes (scrExos) are extracellular vesicles secreted by all cells especially neuroendocrine cells to some extent, circulating in the blood with proteins and nucleic acids.
Aim(s): To explore the proteomics of scrExos as potential diagnostic and theraputic target in GEP-NENs.
Materials and methods: A total of 8 GEP-NENs patients and 8 healthy subjects were involved to detect the discrepant proteins in scrExos by iTraq analyses. Then, cancer tissues and peri-cancer tissues (>5cm distant from cancer) of 43 GEP-NENs patients were included to explore the biofunction of target protein.

#2936 Mutational Landscape of 109 High-Grade Gastroenteropancreatic Neuroendocrine Neoplasms G3
Introduction: Gastroenteropancreatic (GEP) neuroendocrine neoplasms (NEN) G3 are rare with a poor outcome. Molecular data for GEP NEN G3 is limited and the 2019 WHO classification is based on morphology and proliferation rate.

#2970 Characteristics, Treatments and Inflammatory Biomarkers in Patients (pts) with G3 Gastroenteropancreatic (GEP) Neuroendocrine Neoplasms (NENs)
Introduction: Well-differentiated neuroendocrine tumors G3 (NETsG3) pts have a different biological behavior compared to those with neuroendocrine carcinomas (NECs). Sensitivity to platinum depends on Ki67 and there is no standard second line (2L). Neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) are predictive factors of cancer survival, but with limited evidence in NENs.

Introduction: MicroRNAs (miRNA) are small noncoding RNA molecules implicated in the pathophysiology of myriad neoplasms. Clinically useful biomarkers are needed in SB NET to ascertain disease aggressiveness, select treatment strategy, detect early recurrence and monitor response.
