#2999 Aberrant Tryptophan Metabolism in Stromal Cells Is Associated with Mesenteric Fibrosis in Small Intestinal Neuroendocrine Tumours

Introduction: Increased levels of serotonin secretion are associated with mesenteric fibrosis (MF) in small intestinal neuroendocrine tumors (SI-NETs). However, only a proportion of patients with increased serotonin production will develop mesenteric fibrosis.

#2847 Surgical and Survival Outcomes of Early Peptide Receptor Radionuclide Therapy for Downstaging Locally Advanced or Oligometastatic Pancreatic Neuroendocrine Neoplasms

Introduction: Pancreatic neuroendocrine neoplasm (pNEN) patients often present with locally advanced or metastatic disease. The objective response rate of peptide receptor radionuclide therapy (PRRT) in pNENs is 55%. Therefore, PRRT may be a possibility for patients who are not eligible for upfront curative surgery.

#2095 Progression of Mesenteric Metastasis in Small Intestinal Neuroendocrine Tumors

Introduction: A metastatic mesenteric mass is a hallmark of small intestinal neuroendocrine tumours (SI-NETs). However, little is known about the development of a SI-NET associated mesenteric mass over time.

#2092 Palliative Surgery in Advanced Small Intestinal Neuroendocrine Tumors

Introduction: Small intestinal neuroendocrine tumours (SI-NETs) are known to develop mesenteric metastasis and fibrosis. Since this can induce intestinal obstruction, edema and ischaemia, prophylactic palliative resection of the primary tumour and mesenteric mass is often recommended in case of advanced disease but the evidence is disputable.
