#2119 Positron Emission Tomography (PET) Predictors of Tumor Response to Peptide Receptor Radionuclide Therapy (PRRT) in Metastatic Neuroendocrine Tumors (NET)
Introduction: Pretherapeutic 68Gallium-DOTA-(0-Tyr3)-octreotate (68Ga-DOTATATE) PET standardised uptake value (SUV) has shown conflicting results in the prediction of tumour response to radionuclide therapy.

#2069 Tumor Absorbed Dosimetry and Response of Radionuclide Therapy in Metastatic Neuroendocrine Tumor
Introduction: Increased tumour lesion absorbed dosimetry (TLAD) from peptide receptor radionuclide therapy (PRRT) is associated with neuroendocrine tumours (NET) response. Responses to PRRT might be impacted by NET grade, site of origin and use of concurrent chemotherapy.

#2217 Prognostic Impact of CHOI Response Criteria Compared to RECIST in Grade 1-2 Advanced Pancreatic Neuroendocrine Tumors (CRIPNET-GETNE Study-NCT02841865)
Introduction: Response Evaluation Criteria In Solid Tumors (RECIST) are not presumably the most optimal option for predicting the benefit of antiangiogenic drugs in neuroendocrine tumors (NETs), given that tumor shrinkage is not frequent, and qualitative changes in tumor tissues are to be expected.

#804 The Plasma Chromogranin A Level Predicts Survival and Tumor Response in Patients with Gastroenteropancreatic Neuroendocrine Tumors
Introduction: The plasma chromogranin A (CgA) level is a reliable biomarker for identifying patients with advanced gastroenteropancreatic neuroendocrine tumors (GEP-NETs).

#898 Evaluation of Tumor Response to Targeted Therapies in Precision-Cut Slices of Human Pancreatic Neuroendocrine Tumors
Introduction: Patients with PNET might benefit from new therapeutic approaches acting on the mTOR signaling pathway. Culture of precision-cut slices could allow testing these molecules in human tumors, allowing personalized treatments.

#62 Genome-wide DNA methylation profiling of pancreatic neuroendocrine tumors identifies distinct methylation profiles and differentially methylated gene promoter regions associated with low, medium and high grade tumors
Introduction: Integration of genetics and epigenetics has emerged as a powerful approach to studying cellular differentiation (Mikkelsen et al, 2009) and tumorigenesis (Shen et al, 2007). The study of DNA methylation is of particular importance in cancer, as causal involvement has been demonstrated and it is the most stable of all epigenetic modifications, making it a desirable marker for both early detection and treatment of tumors. Hypermethylation of CpG sites in gene promoter regions leads to decreased gene expression; if such a gene is a tumor suppressor, this leads to carcinogenesis. To date, there have been no studies of genome-wide DNA methylation profiling of NETs. This study sets out to determine the DNA methylation profiles of low, intermediate and high grade pancreatic NET liver metastases with the intention of identifying dysregulated biological pathways in the development of these tumors. A protocol for the analysis formalin-fixed paraffin embedded tissue (FFPE) has also been developed in order to study these tumors in significant numbers following this pilot study.

#313 Effect of Somatostatin Analogues in the Control of Tumor Growth in Patients with Metastatic Lung Carcinoid Tumors

#994 Predictive Biomarkers of Response in Patients with Extrapulmonary Neuroendocrine Tumors (EPNET) Treated with Platin-based Chemotherapy
Introduction: EPNET, particularly advanced and Grade 3 (G3) tumors are often treated with chemotherapy. While many patients experience tumor response, those rarely live for more than two years. Predictive markers could potentially help us to tailor the best treatment for these patients (pts).

#1118 Is There an Additional Value of Somatostatin Receptor Subtype 2A Immunohistochemistry Over Somatostatin Receptor Scintigraphy in Predicting Gastroenteropancreatic Neuroendocrine Tumor Response?
Introduction: It is not known whether tumoral somatostatin receptor subtype 2a (sst2a) immunohistochemistry (IHC) has additional value over OctreoScan® uptake in predicting response to PRRT in patients with gastroenteropancreatic neuroendocrine tumors (GEP-NETs).

#1471 Chemotherapy for Stage IV Sporadic Pancreatic Neuroendocrine Tumors (pNET): Are Partial Responses to Post-first Line Chemotherapy Predictable by Response/Type of First Line Chemotherapy?
Introduction: Three types of chemotherapy are recommended for stage IV pancreatic neuroendocrine tumors (pNETs): streptozocin (STZ)-, dacarbazine (DCZ)- and oxaliplatin (OX)-based. Whether cross resistance exists is unknown.
