#2995 Prediction of Symptomatic Mesenteric Mass in Patients with Small Intestinal Neuroendocrine Tumors Using a CT Radiomics Approach

Introduction: A mesenteric mass surrounded by fibrosis is a hallmark feature of small intestinal neuroendocrine tumors (SI-NETs) that can induce severe abdominal complications. To improve clinical outcome, there is a need for personalized treatment strategies based on accurate prediction of development of abdominal complications.

#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.

#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.

#585 Global microRNA profiling of small intestine neuroendocrine tumors (SI-NETs) and establishment of a method to study serum microRNA expression from the same tumors

Introduction: MicroRNAs (miRNAs) are important post-transcriptional regulatorsin biological processes and function either as tumor suppressors or oncogenes.
