#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

#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).

#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.
