#3052 Unique Metastatic Patterns in Neuroendocrine Neoplasms of Different Primary Origin

Introduction: Neuroendocrine neoplasms (NEN) can originate in different organs, e.g. in the gastro-enteric tract (GE), pancreas (P) or lung (L). Despite similarities in clinical and pathological characteristics in tumors of another origin, differences also exist. This might apply to metastatic patterns as well, but only limited data is available so far.

#2845 Primary Tumour Resection and PRRT of NEN Stage IV - Are There Differences in Grading?

Introduction: The resection of primary tumours (PT) in patients with stage IV NEN is still a matter of debate. The resection of tumours with a low proliferation index (G1/G2) is more accepted then the resection of high proliferative tumours (G3-NET / G3-NEC).

#2725 Upfront Surgery in Patients with High-Grade GEP NEN and MINEN: A Nordic Multicenter Study of 201 Patients

Introduction: Surgery is the principal treatment for loco-regional gastroenteropancreatic (GEP) neuroendocrine tumors (NET). However, whether surgery is beneficial in high-grade neuroendocrine neoplasms (NEN) and mixed neuroendocrine-non neuroendocrine neoplasms (MiNEN) is not known.

#2256 Assessment of the Serum Levels of the Soluble Vascular Cellular Adhesion Molecule-1 (sVCAM-1) in Patients with Neuroendocrine Neoplasms

Introduction: Tumor growth and the ability to metastasize is a multistage process involving interactions between cancer cells and the vascular endothelium. These interactions have been reported to be mediated by various molecules including sVCAM-1. We have previously shown elevated serum concentration of sVCAM-1 in 82 neuroendocrine neoplasms (NEN) compared to controls. Here, we present results of the extension of the previous study.

#2202 Assessment of the Clinical Utility of the NETest in a US Registry-Based Study

Introduction: The clinical relevance of molecular biomarkers in oncology management has been recognized in breast and lung cancer. Current biomarkers in NET disease have limited clinical utility.
