#2745 Integrative Genomic Characterization Identifies Molecular Subtypes of Lung Carcinoids

Introduction: Lung carcinoids (LCs) are rare and slow growing primary lung neuroendocrine tumors. The WHO classify LCs into atypical and typical carcinoids. Recent studies have shown that the reproducibility of LCs classification and its prognostic efficacy have high interobserver variability

#2280 The BON-SSTR2 Chicken Chorioallantoic Membrane (CAM) Model for the Analysis of Lu-17-DOTATOC Sensitizing Agents

Introduction: Peptide radioreceptor therapy (PRRT) is a promising therapy option for SSTR2-positive pancreatic neuroendocrine neoplasms (NEN). However, therapeutic effects are often not satisfying concerning sensitivity to PRRT. We hypothesize that the slow proliferation of NENs provides sufficient time for the repair of beta-particle induced-DNA damage. The ubiquitin-proteasome-system is involved in DNA damage repair and affected by the proteasome inhibitor bortezomib (Velcade®). The inhibition of DNA damage repair during PRRT may be an option to improve therapy response in NEN. We have recently demonstrated the damage repair inhibitory and pro-apoptotic effect of bortezomib in NEN in vitro (Briest et al., in revision).

#2135 Is the Classification of Functioning-PanNET/Non-Functioning PanNET Properly? Insulinoma/Non-Insulinoma Is More Suitable to Distinguish the Clinicopathological and Prognosis Difference of Localized Insulinoma

Introduction: Pancreatic neuroendocrine tumor (PanNET) is classified into Functioning (F-PanNET) and Non-functioning (NF-PanNET) by hormone secretion. But insulinoma is slowly proliferating with unique features compared with Non-insulinoma F-PanNET (NiF-PanNET).

#2075 Phase 1 Pharmacokinetic and Pharmacodynamic Study of APOC, a New Controlled Release Formulation (CRF) of 15mg Octreotide Acetate in Healthy Male Volunteers

Introduction: Somatostatin analogues (SSAs) are considered the gold standard for systemic therapy of advanced neuroendocrine tumors (NETs). Octreotide is one of the SSAs most widely used in long-term therapies of NETs. There is increasing evidence that clinical benefits could be obtained with higher SSAs circulating levels but remain unreachable with current products without impacting significantly the quality of life of the patients. APOC is a new injectable controlled release technology containing Octreotide invented and developed by Ascil-Biopharm and designed to cover specifically these clinical unmet needs. It is presented as ready-to-use and can easily be manufactured at selected doses and durations in prefilled syringe.

#1645 A Role of TETs and 5-Hydroxymethylcytosine in SI-NETs

Introduction: Small intestinal neuroendocrine tumors (SI-NETs) are rare and slow growing neoplasms. Identification of patients with worse outcome and of novel potential targets for therapy is important goals. The epigenetic mark 5-hydroxymethylcytosine (5-hmC) is severely reduced in various cancers and was recently found by us to discriminate between parathyroid adenoma and carcinoma. A growth regulatory role of TET1 was also found.
