Differential Somatostatin and CXCR4 Chemokine Receptor Expression in Primary Gastroenteropancreatic Neuroendocrine Neoplasms (GEP-NEN) and Their Metastases Abstract #1302

Introduction: Somatostatin receptors (SSTR) are known for their overexpression in well-differentiated GEP-NEN, where they serve as molecular targets for different imaging and treatment modalities. The chemokine receptor CXCR4, in contrast, is present mainly in highly proliferative and advanced tumors.
Aim(s): Evaluation of the SSTR, CXCR4 and Ki-67 expression in primary tumors (PT) (n=50) and metastases (MTS) (n=76) of GEP-NEN from 3 different places of origin (small intestine, pancreas, colon/rectum).
Materials and methods: The SSTR and CXCR4 expression was determined by means of immunohistochemistry and rated by means of the Immunoreactive Score (0-12 points).

#2853 Succinate Dehydrogenase B (SDHB) Immunohistochemical Expression in Pancreatic Neuroendocrine Tumours and Correlation with Somatostatin Receptor Immunohistochemistry
Introduction: The established category of succinate dehydrogenase (SDH) deficient neoplasms includes several endocrine tumours with recent evidence that pancreatic neuroendocrine tumours (PNETs) could be included in this tumour group. The SDH complex is composed of four subunits (A-D) but loss of immunohistochemical (IHC) expression for SDHB indicates bi-allelic inactivation of any SDH component and is used as a marker for syndromic disease.

#1038 Co-Expression of Somatostatin and CXCR4 Receptors as Targets for Diagnostics and Treatment in Intestinal Neuroendocrine Neoplasms.
Introduction: Somatostatin receptors (SSTR) are widely distributed in well-differentiated neuroendocrine tumors (NET) and serve as primary targets for diagnostics and treatment. An overexpression of the chemokine receptor CXCR4, in contrast, is considered to be present mainly in highly proliferative and advanced carcinomas.

#1347 Evaluation of the Somatostatin, CXCR4 Chemokine and Endothelin A Receptor Expression in a Large Series of Paragangliomas
Introduction: Paragangliomas are predominantly benign tumors, but in some cases invasive growth and also metastasis is observed. Given the limited number of nonsurgical treatment options, novel target structures for diagnostics and therapy of this tumor entity are urgently needed.
