Serum chromogranin A as tumor marker in neuroendocrine tumors Abstract #68

Introduction: Serum chromogranin A (CgA) is used as a tumor marker for neuroendocrine tumors (NETs).
Aim(s): Assessment of the sensitivity of the tumor marker CgA in NETs of the gastroenteropancreatic system.
Materials and methods: CgA levels were measured in serum samples from 110 patients with midgut and pancreatic NETs (n=62 and n=48, respectively) in a retrospective single-center series during clinical routine in the years 2000 – 2009. For CgA determination, a commercially available immunoradiometric assay (IRMA, CIS-Bio) was used (""cutoff"" < 98 ng/ml).

#11 Plasma chromogranin - A response to octreotide test: Prognostic value for clinical outcome in endocrine digestive tumors
Introduction: Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) expressing somatostatin receptors may be treated with somatostatin analogues (SSAs). Selection criteria are a positive Octreoscan® or a >50% hormone level decrease after octreotide s.c. injection (octreotide test) (OT). Plasma chromogranin A (CgA) is the best general GEP-NET marker, but data on CgA response to OT are scant.

#12 Chromogranin A as a predictor of progression, regression or stable disease in ileo-cecal (midgut) carcinoid tumors
Introduction: A general characteristic for NETs is their expression of certain proteins, such as chromogranin A (CgA), which is released from the dense core vesicles of NE cells, occasionally together with cell specific hormones, such as gastrin and serotonin. Plasma CgA seems to be closely related to tumor burden of intestinal carcinoid tumors in humans.

#16 Endoglin as indicator of metastatic neuroendocrine tumors of the pancreas
Introduction: Neuroendocrine tumors of the pancreas are rare, highly vascularized tumors. Endoglin, a Transforming Growth Factor-β co-receptor, is a marker for angiogenic endothelial cells. Angiogenesis is required for tumor progression and the development of metastases. Recently, endoglin expression was found to be a prognostic marker in pancreatic carcinomas. However, the role of endoglin in neuroendocrine pancreatic tumors has so far not been studied.

#20 Paraneoplastic antigen Ma2 (PNMA2) auto-antibodies as biomarkers for early small intestine neuroendocrine tumors detection
Introduction: Small intestine neuroendocrine tumors (NETs) comprise well-differentiated NET (benign carcinoid), well-differentiated neuroendocrine carcinoma (malignant carcinoid) and poorly differentiated neuroendocrine carcinoma (NEC). The majority of NET patients have developed liver metastases at the time of diagnosis and surgery is then seldom curative. Novel predictive, diagnostic and prognostic markers are thus needed to improve our capabilities to diagnose and cure these tumors. We have previously identified six novel marker genes for neuroendocrine tumor cells by using Affymetrix microarrays and advanced bioinformatics. One of this markers, the paraneoplastic antigen Ma2 (PNMA2), which is normally expressed only in nervous tissue, can in the process of carcinogenesis be detected in tumors located outside the nervous system. The finding that Ma2 is expressed in small intestine neuroendocrine primary tumors and their metastases made it interesting to screen whether antibodies against Ma2 are present in the serum of NET patients.

#25 Predictors of response to radio-embolization (TheraSphere ®) treatment of neuro-endocrine liver metastasis
Introduction: Neuroendocrine tumors (NET) frequently metastasize to the liver. Most patients have diffuse, and therefore incurable, disease. NET liver metastasis has been shown to respond to yttrium-90 microspheres therapy. This study aims to define factors that predict response to radio-embolization in patients with NET liver metastases.
