#27 Combined treatment of rapidly progressing neuroendocrine tumors by transcatheter arterial chemoembolisation of the liver and peptide-receptor radiotherapy is save and effective. Report of thirty consecutive patients
Introduction: Patients with rapidly progressing neuroendocrine tumors presenting with high tumor load and/or severe clinical syndromes are clinically challenging and with limited life expectany. Peptide receptor radiotherapy (PRRT) and transcatheter arterial chemoembolization (TACE) have demonstrated efficacy in the treatment of neuroendocrine tumors. However, there are no reports that both therapies have been applied in combination.

#1003 Signalling Pathways in Bronchial Neuroendocrine Tumor Disease and Its Translation to Innovative Targets: The New Kid on the Block
Introduction: Bronchial neuroendocrine neoplasias comprise a wide spectrum of well-differentiated tumors (typical/atypical carcinoids) to undifferentiated carcinomas such as small (SCLC) and large cell (LC) neuroendocrine carcinomas with a fatal prognosis. Therapeutic options are unsatisfactory.

#1172 Dual Inhibition of PI3K and mTORC1/C2 by PKI-587 (PF-05212384) as a Promising Therapeutic Option for Gastroenteropancreatic Neuroendocrine Tumor Disease and Its Effect on AKT-Signaling
Introduction: Gastroenteropancreatic neuroendocrine neoplasms (GEP-NEN) are heterogeneous in their clinical behavior and therapeutic options are still not satisfactory. The “crosstalk” of different signaling pathways in NEN cells appears to be more complex as known already. PKI-587 is a highly potent novel dual inhibitor of PI3K and mTORC1/C2.

#1199 Tumor Infiltrating Lymphocytes and PD-L1 Expression Differ in Low and High Grade Neuroendocrine Tumors
Introduction: Although much progress has been made in the past 2-3 years in terms of understanding signaling pathways in gastroenteropancreatic neuroendocrine tumors (GEP-NENs), approved treatment options are still limited. Cancer Immunotherapy has been announced as the breakthrough of the year in 2013 and might become an integral part of the clinical management strategy for solid tumors including GEP-NENs. Therefore, to develop immunotherapeutic strategies against NENs we need to know which immune escape mechanisms are relevant in high and low grade NEC/NENs.

#1404 The Proteasome Inhibitor Bortezomib Is a Highly Effective Treatment Option for Gastroenteropancreatic Neuroendocrine Neoplasms and Sensitizes to DNA Damaging Therapy In Vitro
Introduction: Gastroenteropancreatic neuroendocrine neoplasms are fairly rare tumors with very heterogeneous behavior and molecular characteristics. Their generally slow proliferation render them virtually resistant to many DNA damaging therapeutic approaches. Bortezomib has been shown to be effective in GEP-NENs in vitro but has been withdrawn from clinical assessment due to a small phase II study on bortezomib monotherapy in 2004.

#1507 The CDK4/6 Inhibitor Palbociclib Induces Anti-proliferative Mechanisms in Gastroenteropancreatic Neuroendocrine Neoplasms In Vitro
Introduction: Gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs) are rare tumors with heterogeneous molecular backgrounds and mostly unknown druggable driver mutations. Especially for the midgut NENs effective treatment options are limited. The retinoblastoma pathway is often inactive due to CDK4/6 overexpression in pancreatic NENs. Palbociclib is a FDA approved (ER-positive and HER2-negative breast cancer) cyclin-dependent kinases 4 and 6 inhibitor and might impair cell cycle progression and proliferation.

#1524 Is mTOR Pathway Activity a Good Predictor for Everolimus Therapy? A Pilot Study to Build Up a Phase II Trial in Pancreatic Neuroendocrine Neoplasias (pNENs)
Introduction: Everolimus (EVE) is an approved treatment for progressive well-differentiated pNENs and usually induces stable disease. Until now, there is no reliable biomarker for the response to EVE.

#1542 Selective Inhibition of PI3Kalpha (BYL719) - Promising Therapeutic Option for Neuroendocrine Tumors?
Introduction: Neuroendocrine tumors are heterogeneous, often functional malignancies and their therapeutic options are limited. As the PI3 kinase signaling is ­in GEP-NENs, selective PI3Kalpha inhibitors may be more potent than panPI3K inhibitors.

#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.

#2275 Analysis of Gene Expression Patterns of Rectum Neuroendocrine Tumors (NET) Versus Healthy Tissue Reveals Alterations in the MAPK and WNT Signaling Pathways
Introduction: The neuroendocrine tumors (NETs) of the rectum are rare but increasing in incidence, by means of improved endoscopic techniques and histological reporting. They often occur as small polypoid lesions and G1, and in most cases an incidental finding at endoscopy.
