#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.

#1150 Platelet Serotonin But Not Dopamine Concentrations Are Lower in Pancreatic Neuroendocrine Tumor and Renal Cell Carcinoma Patients Compared to Healthy Individuals.
Introduction: Platelets carry VEGF-A, serotonin and dopamine. Serotonin stimulates and dopamine inhibits tumor angiogenesis. We hypothesized that platelets are activated in tumor vasculature and release angiogenic factors, resulting in lower platelet serotonin and dopamine.

#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.

#2772 Vitamin Supplementation and a Personalized Diet in Patients with Neuroendocrine Tumors: The DIVIT Study
Introduction: Patients with neuroendocrine tumors (NETs) are at risk for vitamin deficiencies and poor nutritional status due to excessive serotonin production, diarrhea, previous gastrointestinal surgery, and/or treatment with somatostatin analogues (SSA). Little knowledge exists about vitamin deficiency and how patients should be supported for the deficiencies they develop during their long-lasting disease.
