#2795 Molecular Correlation of the Activity of Evofosfamide (EVO) in Combination with Sunitinib (SUN) in Pancreatic Neuroendocrine Tumors (pNETs) in the SUNEVO GETNE Trial

Introduction: MEN1, DAXX, ATRX, and PI3K/AKT/mTOR pathway genes are frequently mutated in pNETs. Sunitinib is approved and widely used in the metastatic setting but unfortunately, no validated predictive biomarker has been identified to guide therapy yet. The SUNEVO phase II trial of the Spanish Task Force Group for Neuroendocrine and Endocrine Tumours (GETNE) trial combined the pro-drug of EVO under SUN-induced hypoxic conditions.

#2283 Ultra-Deep Targeted Resequencing Reveals Recurrent DAXX and CYFIP2 Mutations and Implicates Novel Pathways in Pancreatic Neuroendocrine Tumors

Introduction: Recent studies in pancreatic neuroendocrine tumors have identified mutations in DAXX/ATRX, MEN1, and genes involved in the phosphoinositide-3-kinase/Akt/mammalian target of rapamycin (PI3K-Akt-mTOR) pathway. However, these studies focused on abundant mutations.

#1939 Antiproliferative Effects of Lanreotide in Neuroendocrine Tumors

Introduction: Neuroendocrine tumors of the lung (BP-NETs, typical (AC) and atypical Carcinoids (ATC)) are rare tumors with heterogeneous behavior and molecular characteristics. For the intermediate proliferating BP-NETs treatment options are limited and unsatisfactory. Somatostatin analogues have not only anti-secretory effects, but also display antiproliferative features, as shown by PROMID and CLARINET trial. Nevertheless, their value in BP-NET is undefined so far.

#1869 Synergistic Effects of Combining Hsp90 and PI3K Inhibitors with Everolimus in Pancreatic Neuroendocrine Tumors

Introduction: The development of the first molecular targeted therapies for neuroendocrine tumors (NET) was a milestone in the treatment of patient. Nevertheless, these therapies eventually fail and patients become resistant to the treatment. One way of escaping this dilemma might be the combination of targeted drugs to prevent resistance development.
