#990 Prolonged Progression-Free Survival with Extended Cycle Streptozotozin/5-FU Chemotherapy in Patients with Metastatic Pancreatic Neuroendocrine Tumors
Introduction: The treatment of pancreatic neuroendocrine tumors with streptozotocin-based chemotherapy is well-established.
Conference: 11th Annual ENETS Conference (2014)

Keywords: chemotherapy
#1183 Establishment of a New Human Pancreatic Neuroendocrine Tumour Cell Line
Introduction: The development of new therapeutic strategies for patients with pancreatic neuroendocrine tumours is impaired by the paucity of suitable pre-clinical models. Although the two available tumour cell lines BON and QGP have a neuroendocrine phenotype, the proliferation rate is too high for a well differentiated neuroendocrine tumour.

#1553 A Novel In Vitro Model of a Highly Proliferative Pancreatic Neuroendocrine Neoplasia
Introduction: Transformation of well-differentiated neuroendocrine tumors into highly proliferative neuroendocrine neoplasms is a rare, but clinical relevant phenomenon. So far, it is unclear whether these tumors should be treated in analogy to neuroendocrine tumors or as bona fide neuroendocrine carcinoma.

#1573 Regulation of Neuroendocrine Differentiation by Growth Factor Induced Proliferation in a Well-differentiated Pancreatic Neuroendocrine Tumor Cell Line
Introduction: The regulation of neuroendocrine differentiation in NET tumor cells is poorly understood. Clinical experience suggests a correlation between proliferation and neuroendocrine de-differentiation.

#1850 Influence of VEGF Splicing on Microvessel Density and Architecture in Pancreatic Neuroendocrine Tumours
Introduction: Hypoxia in human tumours is associated with a poor prognosis and is characterized by the stabilization of HIF1α, upregulation of VEGF, and a high microvessel density (MVD). Interestingly, although pancreatic neuroendocrine tumours (pNETS) showing hypoxia signalling also have a poor prognosis, they paradoxically display a low MVD. We hypothesized that this paradoxon might be explained by alternative splicing of VEGF.

#1867 Establishment of the First Well-Differentiated in Vivo Human Pancreatic Neuroendocrine Tumor Model
Introduction: The development of new therapeutic strategies for cancer patients relies on the in vitro and in vivo testing of novel substances in the pre-clinical setting. So far, this has not been possible for pancreatic neuroendocrine tumors (pNET) due to lack of suitable animal models resembling the disease course in human patients.

#1869 Synergistic Effects of Combining Hsp90 and PI3K Inhibitors with Everolimus in Pancreatic Neuroendocrine Tumors
Introduction: The development of the first molecular targeted therapies for neuroendocrine tumors (NET) was a milestone in the treatment of patient. Nevertheless, these therapies eventually fail and patients become resistant to the treatment. One way of escaping this dilemma might be the combination of targeted drugs to prevent resistance development.

#1911 Histological Differentiation Provides Useful, Additive and Independent Prognostic Information to Proliferation Index in G2 and G3 Gastroenteropancreatic Neuroendocrine Neoplasms (GEP-NENs)
Introduction: The WHO 2010 classification has provided a valuable tool to stratify NEN prognosis based on an objective measure, the proliferation index. However, morphology and, in particular, tumor differentiation, is emerging again as a relevant feature that should not be dismissed due to its important clinical implications.

#2120 One Year Experience with Lutetium-DOTATATE for Disseminated NETs in the Gregorio Marañon Hospital
Introduction: The main curative therapy for NET is surgical resection when the disease is localized. But high percentage of patients is diagnosed with advanced disseminated disease and the peptide receptor radionuclide therapy (PRRT) with somatostatin analogs (SSA) is an emerging effective treatment.

#2270 Development of Pre-Clinical NEN Models – Limitations and Opportunities
Introduction: Pre-clinical research in neuroendocrine neoplasia (NEN) has long been impaired by the paucity of NET and NEC cell lines. Furthermore, established models have not been widely available or displayed unusual features (eg. p53 and ras mutations, high proliferation rate).
