#4566 Predictive value of high-risk histopathological- and molecular criteria for lymph node metastasis in appendiceal neuroendocrine tumours

Introduction: Appendiceal neuroendocrine tumours (aNET) are rare neoplasms for which consensus is needed for follow-up and additional treatment. To unravel the factors behind aNET which showed lymph node metastasis (LNM) in additional right hemicolectomy (RH), we evaluated high-risk histopathological parameters in aNETs and studied molecular parameters.

#3438 Risk factors for complications after surgery for pancreatic neuroendocrine tumors

Introduction: Surgical resection is the only potentially curative treatment for pancreatic neuroendocrine tumors (pNETs). The choice for the type of procedure is influenced by the expected oncological benefit and the anticipated risk of procedure-specific complications.

#3103 Comparison of 18F-DOPA versus 68Ga-DOTA-TOC as preferred PET imaging tracer in well-differentiated neuroendocrine neoplasms

Introduction: 18F-DOPA and 68Ga-DOTA-TOC are two diagnostic PET tracers used in neuroendocrine neoplasms (NENs). As both tracers utilise different metabolic pathways, lesion detection results often show disparities, but comparative studies are lacking.

#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.
