#3250 High TMB and MSI-high as independent predictors of survival in NENs

Introduction: To date, there are no validated molecular biomarkers for personalized therapy in NENs. Tumor genome sequencing may help unravel NEN molecular landscape and identify novel targets for an individualized approach.

#2974 MEK/RAF and PARP as Novel Targets in Neuroendocrine Neoplasms – First Results from a Molecular in vitro Tumor Board

Introduction: Neuroendocrine neoplasms (NEN) are a heterogeneous group comprising well differentiated neuroendocrine tumors (NET) and poorly differentiated neuroendocrine carcinomas (NEC). Although, major progress has been made in the development of targeted therapies in various cancers, establishment of a promising personalized therapy in NEN is still pending. So far, a lack of suitable preclinical models represent a major challenge concerning the validation of a mutational based targeted therapy (MBTT)

#2964 Personalized Therapy in a Case of Esophageal NEC Based on Tumor Genome Sequencing

Introduction: High-grade esophageal neuroendocrine carcinomas (NEC) constitute a rare subgroup of neuroendocrine neoplasms, with a particularly aggressive behaviour and unfavourable prognosis. To date, there are no validated biomarkers for personalized therapy and cytotoxic chemotherapy remains the standard of care. However, tumor genome sequencing may help improve NEC molecular landscape knowledge in order to identify novel targets for an individualized approach.

#1638 3D Primary Cell Culture: A New Promising Preclinical Model for Pancreatic Neuro-Endocrine Tumors (pNETs).

Introduction: The lack of adequate in vitro and in vivo preclinical models has hampered the identification of novel treatment options and the development of personalized therapy selection for pNET patients.
