#2868 Differential Gene Expression May Predict Response to Somatostatin Analogues (SSAs) in Gastrointestinal (GI) Neuroendocrine Tumors (NETs)

Introduction: SSAs are commonly used to treat GI NETs as they have anti-secretory and antiproliferative effects. However, genetic markers predicting response to SSAs are lacking.

#2819 Occurrence of Pancreatic Exocrine Insufficiency in Patients with Advanced Neuroendocrine Tumours Treated with Somatostatin Analogue

Introduction: Neuroendocrine neoplasia (NENs) are heterogeneous tumours caracterized by a relatively indolent rate of growth. Usually, in G1 and G2 GEP-NENs, first-line therapy is SSAs, considering their efficacy, good safety profile, and antiproliferative effects. SSA treatment inhibits the production and excretion of pancreatic enzymes and PEI is known to be an adverse effect of SSA treatment.

#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.

#1734 Efficacy of Lanreotide (LAN), Both Alone and in Combination with Targeted Therapies in a Preclinical Model of Pancreatic Neuroendocrine Tumors (pNETs)

Introduction: CLARINET trial has proven the antiproliferative effects of LAN in patients with non-functioning gastro-entero-pNETs. However, the combination of LAN with targeted therapies is widely used in clinical practice and should be further evaluated.

#1001 Forkheadbox Proteins as Novel Drug Targets in Gastroenteropancreatic Neuroendocrine Tumor Disease: Inhibition of FoxM1 Exerts Antiproliferative Effects in GEP-NEN Cell Lines

Introduction: Forkheadbox proteins (Fox proteins) are transcriptions factors. They are highly conserved key players in a large number of cellular processes. Fox proteins have been described as acting as both tumor suppressors and oncogenes. Most notably, they operate in the context of the majority of cancer-related pathways. Information about the fuunction of these proteins in gastroenteropancreatic neuroendocrine neoplasias is scant.
