#3320 TGF-β increase caspase activation and migration in typical bronchial carcinoids

Introduction: Typical bronchial carcinoids (TBC) are well-differentiated neuroendocrine neoplasms (NEN) whose management can still be very challenging due to reduced sensitivity to therapy. Previous studies have reported TGF-β’s ability to activate mTOR pathway and induce epithelial to mesenchymal transition (EMT). Moreover, preliminary results show an overexpression of TGF-β signalling and caspase activation in TBC.

#3072 Rb and p53 Status Determination by Immunochemistry Is Complementary in Routine Practice to Genetic Testing of Neuroendocrine Neoplasms

Introduction: Rb and p53 status may help distinguishing well from poorly differentiated neuroendocrine neoplasms (NEN) and may predict response to chemotherapy. Studies correlating Rb/p53 genetic and immunohistochemistry were performed on high-quality frozen samples with high throughput techniques efficient for copy number determination. This situation differs from routine practice in which small deletions may be hard to detect on formalin-fixed paraffin-embedded (FFPE) samples with a gene panel approach.

#3054 Nutritional Status and Considerations for Patients Diagnosed with a Gastroenteropancreatic Neuroendocrine Tumour: Nutrition in NETs Study

Introduction: Gastroenteropancreatic neuroendocrine tumours (GEP NET) can adversely affect nutritional status. Cross-sectional studies report up to 25% of GEP NET patients are malnourished and dietary change may be prevalent. Nevertheless, clinical guidelines lack advice on nutrition management.

#3050 Radioembolization for Neuroendocrine Liver Metastases: An Institutional Case Series, Systematic Review and Meta-Analysis

Introduction: Neuroendocrine liver metastases are clinically challenging and often non-resectable due to their frequent disseminated distribution. Radioembolisation with yttrium-90 labelled microspheres represents an emerging modality for NELM.

#3034 Somatostatin Analogs for Pancreatic Neuroendocrine Tumors: Is There Any Benefit When Ki-67 Is ≥ 10%?

Introduction: The antiproliferative effect of first-line long acting somatostatin analogs (SSA) in advanced gastro-entero-pancreatic neuroendocrine tumors (GEP-NETs) was shown in the PROMID and the CLARINET trials. Efficacy data in pancreatic NETs (PanNETs) with Ki-67 ≥ 10% are limited.
