#39 Specialist dietetic input and nutritional outcomes in Neuroendocrine Tumour Patients
Introduction: Neuroendocrine tumors (NETs) are a heterogeneous group of tumors that are complex to manage and require a multidisciplinary approach. The most common primary sites are the small intestine and pancreas. The disease itself, as well as sequelae from surgery and medical therapy, can have a negative impact on patients’ nutritional status. Weight loss is known to be a poor prognostic indicator.

#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.

#88 EpCam expression and detection of circulating tumor cells in neuroendocrine tumors
Introduction: Using the CellSearchTM system, circulating tumor cells (CTCs) can be reproducibly enumerated according to expression of EpCAM and cytokeratins 8, 18 or 19 and the absence of the haemopoietic marker CD45. The number of CTCs detected in 7.5 mls blood has been shown to correlate with prognosis in breast, colon and prostate cancer and can predict response to therapy. Neuroendocrine tumors (NETs) have not previously been reported to express EpCAM and have not been systematically assessed for presence of CTCs. We have therefore explored the expression of EpCAM in NETs and the detection of NET cells in the circulation.

#124 Management and outcomes of malignant paragangliomas and phaeochromocytomas
Introduction: Chromaffin-cell tumors include phaeochromocytomas and paragangliomas, represent a rare group of neuroendocrine tumors and are located in adrenal medulla or extra-adrenal sites, respectively. Ten percent of phaeochromocytomas and 15-35% of paragangliomas are malignant.

#129 Grade according to Ki-67 or mitotic count in gastroenteropancreatic neuroendocrine tumors
Introduction: Gastroenteropancreatic neuroendocrine tumors (NETs) are uncommon tumors with a reported incidence of 2.5-5 per 100000 population. The recent classification system of NETs proposed by the European Neuroendocrine Tumor Society (ENETS) uses both Ki-67 labelling index and mitotic index to assign grade (low, intermediate, high). It has been adopted into routine practice but there is limited data on the relationship between these indices and their effect on classification.

#130 Lanreotide Autogel for malignant carcinoid syndrome: an 8-year experience
Introduction: Somatostatin analogues provide symptomatic relief in carcinoid syndrome and recently have been shown to inhibit tumor growth in metastatic gastroenteropancreatic neuroendocrine tumors (NETs). Lanreotide compounds are reported to have similar efficacy to Octreotide compounds. There is limited long-term data available on Lanreoitde Autogel.

#205 Integrated Genome-Wide DNA Methylation and mRNA Expression Analysis of Pancreatic NETs Identifies Differential Activation of the Hypoxia Inducible Factor (HIF) Pathway Between Low and Intermediate Grade Tumors
Introduction: This is the first study to integrate DNA methylation and mRNA expression analysis in NETs. It is a powerful approach with which to identify disrupted biological pathways in NET pathogenesis.

#230 Long-term Follow-up of Tissue Valve Prostheses in Carcinoid Heart Disease
Introduction: Development of carcinoid heart disease (CHD) increases morbidity and mortality. Cardiac valve replacement surgery improves functional class, but tissue prosthesis degeneration can occur early in CHD.

#243 Morbidity and Mortality Associated with Desmoplasia in Midgut Neuroendocrine Tumors (NETs)
Introduction: The clinical course of midgut NETs may be heavily complicated by problems related to mesenteric desmoplasia, causing symptoms secondary to mesenteric artery/vein occlusion and bowel obstruction.

#244 Challenges in the Management of VIPoma Patients
Introduction: VIPomas are a rare neuroendocrine tumor (NET). 90% are pancreatic. 40-70% are metastatic at presentation. The VIPoma syndrome is characterized by secretory diarrhoea, hypokalaemia and achlorhydria.
