#670 The Relationship Between the Ki-67 Protein and IGF-Related Genes in Gastroenteropancreatic Neuroendocrine Tumor Patients with Normal and Elevated Serum Chromogranin-A
Introduction: GEP-NETs are rare, heterogeneous neoplasms with a distinct biological and clinical behavior. Both IGF-system and Ki-67 indices have been reported as important stimulating factors in carcinogenesis and/or tumor progression. The tumor marker CgA is an independent predictor for survival as well. Currently no data are available about a possible interaction between IGF-system (IGF(-R)s, IRs, BPs) and Ki-67 protein in GEP-NET patients with normal and elevated serum CgA.

#1118 Is There an Additional Value of Somatostatin Receptor Subtype 2A Immunohistochemistry Over Somatostatin Receptor Scintigraphy in Predicting Gastroenteropancreatic Neuroendocrine Tumor Response?
Introduction: It is not known whether tumoral somatostatin receptor subtype 2a (sst2a) immunohistochemistry (IHC) has additional value over OctreoScan® uptake in predicting response to PRRT in patients with gastroenteropancreatic neuroendocrine tumors (GEP-NETs).

#1480 Systemic Treatment Sequences across Europe for Patients (pts) with Advanced Non-functional (NF) Well-Differentiated Pancreatic Neuroendocrine Tumours (WD pNETs)
Introduction: Different systemic therapies (ST) are available for pts with advanced WD pNETs; however, the best treatment modalities and optimal sequencing are currently unknown.

#1517 Additional Value for Urinary 5-Hydroxyindoleacetic Acid as Prognostic Marker in Neuroendocrine Tumors?
Introduction: 5-Hydroxyindoleacetic Acid (5-HIAA) is of value for diagnosis of NETs and correlates with severity of carcinoid syndrome. However its value for determining prognosis is uncertain, particularly in combination with other biomarkers

#1543 Is True Non-Secretion of Chromogranin A an Unfavorable Prognostic Factor in Patients with ENETs TNM Stage IV Gastroenteropancreatic Neuroendocrine Tumors?
Introduction: Chromogranin A (CgA) is the best available serum marker for the work-up of gastroenteropancreatic NETs (GEP-NETs) and correlates with tumor volume & biological activity. During diagnosis & follow-up we found patients with elevated CgA levels and patients without elevated CgA levels (=‘true non-secretors’). We postulated that lack of secretion is a sign of dedifferentiation with a poorer prognosis.
