#1656 A Role for Vitamin D in the Gastro-Entero-Pancreatic Neuroendocrine Neoplasms Outcome: Report on a Series from a Single Institute. 
Introduction: Vitamin D deficiency is hypothesized to represent a risk factor in several neoplasms.

#2147 Nutritional Assessment and Vitamin Deficiencies in Patients with NETs
Introduction: As a result of disease or related to its management, patients with neuroendocrine tumours may have altered gut or pancreatic function that can cause nutritional deficiencies.

#1998 Vitamin D, Bone Mineral Density and Fracture Risk Assessment in Patients with Neuroendocrine Tumors
Introduction: Some papers have recently described an association between neuroendrocrine tumors (NET) and both vitamin D deficiency (VDD) and low bone mineral density (BMD). The ten-year risk of osteoporotic fractures can be calculated with the FRAX algorithm.

#1288 Vitamin D Deficiency as a Risk Factor in Pancreatic Neuroendocrine Neoplasms: Report from a Series at a Single Institute
Introduction: Vitamin D deficiency (VitDdef) is hypothesized to represent a risk factor in several neoplasms. To date, vitamin D levels have not been previously evaluated in patients with pancreatic neuroendocrine neoplasms (pNENs).

#1289 Reduced 25-OH-Vitamin D Levels in Patients with Chronic Autoimmune Atrophic Gastritis
Introduction: Chronic atrophic autoimmune gastritis (CAAG) is characterized by parietal cells disruption leading to hypochlorhydria and vitamin B12 malabsorption. An increased risk of osteoporosis was reported in patients with long-standing hypochlorhydria. Only few studies reported a possible association between CAAG and 25OHVitamin D (25OHvitD) deficiency.

#2078 Self-Reported Side Effects in Neuroendocrine Tumor (NET) Patients Prescribed Somatostatin Analogues – The Role for Specialist Dietitians and Nurses
Introduction: In practice, many patients with NETs report a change in symptoms after starting somatostatin analogues (SSA’s). Many health professionals and NET patient advocates have noticed that some of the side effects experienced by patients are more common than patient information literature suggests. It is therefore important to ask what and how severe experiences are, and compare to literature, to help raise awareness amongst NET health professionals.

#1099 Niacin (vitamin B3) Suppletion in Patients with Serotonin Producing Neuroendocrine Tumors
Introduction: Tryptophan is the precursor of serotonin and niacin (vitamin B3), critical for normal cellular metabolism. Tryptophan and niacin can be deficient in patients with serotonin producing neuroendocrine tumors (NETs). Niacin deficiency can lead to symptoms including pellagra.

#1884 Towards Optimal Personalized Diet and Vitamin Supplementation in NET Patients; A Feasibility Study
Introduction: Patients with a neuroendocrine tumor (NET) often have gastro-intestinal complaints due to somatostatin analogue (SSA), tumor mass, secretion of neuroendocrine amines or treatment. This can lead to impaired absorption of critical food components such as vitamins. Serotonin producing NET patients may also have low plasma tryptophan.

#533 Gastric Neuroendocrine Tumor Type 1 Associated with Autoimmune Polyglandular Syndrome Type 3B: A Case Report
Introduction: Gastric neuroendocrine tumors (GNET) are most commonly associated with pernicious anemia and hypergastrinemia. The coexistence with other endocrinological deficiencies is uncommon.

#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.
