#2841 Novelties in Primary and Metastatic GEP-NENs Clinical Outcome Investigation

Introduction: Gastro-entero-pancreatic neuroendocrine neoplasms (GEP-NENs) WHO classification, using strict cut-offs, should reflect their biological features. In real world, strict cut-offs not adequately segregate prognostic groups, in particular on metastasis (M).

#2750 Progression-Free Survival and Clinical Outcomes with Long-Term Use of Telotristat Ethyl in US Clinical Practice

Introduction: Treatment of advanced neuroendocrine tumors aims to relieve symptoms and suppress tumor growth. Primary findings from the TELEACE study suggested telotristat ethyl (TE) may reduce tumor size and impact tumor growth.

#2266 Prognostic Value of the Different Pre-Treatment Biomarkers for Patients with Neuroendocrine Tumors

Introduction: Several inflammatory response materials could be used for prediction of prognosis in cancer patients. The neutrophil lymphocyte ratio (NLR), platelet lymphocyte ratio (PLR), thrombocytosis (the platelets number >400*103/mm3) have been introduced for prognostic scoring system in various cancers.

#2108 Molecular Characterization of Primary and Metastatic Pancreatic Neuroendocrine Tumors

Introduction: Pancreatic neuroendocrine tumours (PNETs) are a heterogeneous group of rare pancreatic neoplasms often diagnosed with distant metastases, which are associated with significantly poorer prognosis. Recurrent somatic mutations, chromosomal aberrations and gene expression signatures in PNETs have been described, but the clinical significance of these molecular changes is still poorly understood, and the clinical outcomes of PNET patients remain highly variable.
