#2905 DNA Methyltransferase Inhibitor Hydralazine Induces Upregulation of Somatostatin Type 2 Receptors in Human Neuroendocrine Tumor Cells
Introduction: Epidrugs like DNA methyltransferase inhibitors (DNMTi) can increase somatostatin receptor type 2 (SST2) expression in neuroendocrine tumor (NET) cells in vitro and in vivo. This effect could be used for NET patients with low SST2 expression who are currently ineligible for somatostatin analogue (SSA) treatment. However, the DNMTi known to stimulate SST2 have either a high toxicity profile or are not yet approved.

#2988 Epigenetic Treatment with Histone Deacetylase Inhibitor Enhances Uptake of [111In]In-DOTA-TATE by Increased SST2 Expression on Neuroendocrine Tumor Cells
Introduction: The somatostatin-2 receptor (SST2) is a target for peptide receptor radionuclide therapy (PRRT) in neuroendocrine tumors (NETs). By using epigenetic drugs, which can regulate gene transcription, PRRT efficacy may be further improved due to enhanced SST2 expression.

#3030 Targeting CXCR4 and Thioredoxin Reductase in Theranostics of Atypical Carcinoid and Neuroendocrine Carcinoma
Introduction: Atypical carcinoid and small cell lung cancer (SCLC) are currently incurable. There is thus a critical need for new diagnostic and therapeutic strategies for lung neuroendocrine neoplasms (LNEN). Chemokine receptor 4 (CXCR4), a G protein coupled receptor and theranostic target, plays a crucial role in metastases of LNEN. We hypothesize combination of thioredoxin reductase (TR) inhibitor represents a metabolic strategy to enhance cytotoxicity in peptide-receptor radionuclide therapy (PRRT) of LNEN.

#1559 MTOR Controls an Epigenetic Program Leading to Autophagy and Cell Growth Control
Introduction: Makroautophagy represents an evolutionary highly conserved process involved in the clearance of proteins and organelles. The induction of this central cellular process is tightly connected with programs regulating cell growth control. While the cytoplasmic machinery that orchestrates autophagy is relatively well understood the key epigenetic events that initiate autophagy-related cell growth programs remain largely unknown.

#2793 A Phase II, Open-Label, Multicenter Trial of Avelumab in Patients with Advanced, Metastatic High Grade Neuroendocrine Carcinomas NEC G3 (WHO 2010) Progressive after First-line Chemotherapy (AVENEC)
Introduction: High grade Neuroendocrine Neoplasias (NEN) are rare tumors with a poor prognosis and no established second line therapy.

#2874 Role of FOXM1 in Aggressive Pancreatic / Pulmonary Neuroendocrine Carcinomas and Anti-Tumor Effect of the FOXM1 Inhibitor Thiostrepton
Introduction: DNA-targeting agents are the main treatment of aggressive pulmonary and pancreatic neuroendocrine carcinomas (NEC). FOXM1 is a transcription factor controlling cell proliferation and DNA repair pathways, playing therefore an important role in tumor progression and chemoresistance.

#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)

#2796 Avelumab for Advanced Merkel Cell Carcinoma in the Netherlands; A Nationwide Survey
Introduction: Merkel cell carcinoma (MCC) is a rare, tumor of the skin associated with high recurrence rates and poor survival. Clinical trials have shown activity of checkpoint inhibitors targeting programmed death-(ligand)-1 (PD-(L)1). Avelumab is the only PD-L1 inhibitor that has been approved in the Netherlands for advanced/metastatic MCC (mMCC).

#2822 Outcome of Systemic Therapy in Secondary High-Grade Pancreatic Neuroendocrine Tumors
Introduction: Platinum-based chemotherapy has been the recommended treatment for metastatic high-grade pancreatic neuroendocrine neoplasms (panNEN). This strategy has been questioned for pancreatic neuroendocrine tumor grade 3 (panNET G3). The most optimal treatment strategy for low/intermediate grade panNETs that show progression to a high grade (secondary panNET G3) is unknown.

#2983 Differential TGF-β Signalling in Typical and Atypical Bronchial Carcinoids
Introduction: Typical and atypical bronchial carcinoids (TBC and ABC) are well-differentiated neuroendocrine neoplasms (NEN). Metastatic BC having low to moderate mitotic count may still be treated with somatostatin analogues and mTOR inhibitors; however, TBC and ABC have been reported to respond very differently to therapy and an effective treatment algorithm is still lacking. TGF-β is known for its ability to activate mTOR pathway and induce epithelial mesenchymal transition, affecting cell pathophysiological capabilities such as proliferation, migration and tissue invasiveness.
