#74 Non-functioning pancreatic endocrine tumors: diagnostic criteria and surgical treatment
Introduction: Neuroendocrine tumors were considered rare tumors several years ago. Several reports published recently have observed increased incidence of NETs suggesting that NETs are more prevalent than previously reported. Non-functioning pancreatic endocrine tumors (NFPETs), better defined as non-hyperfunctioning, are characterized by the absence of clinical or biochemical evidence of hormone hypersecretion. From the clinical standpoint, NFPETs can be either occasionally encountered or manifest clinically similar pancreatic tumors. Since both NFPET treatment and prognosis significantly differ from that of ductal adenocarcinoma and other pancreatic malignant tumors, an accurate differential diagnosis is needed.

#17 Diagnostic efficacy of the secretin stimulation test for the Zollinger-Ellison syndrome: an intra-individual comparison using different dosages in patients and controls
Introduction: The diagnosis of Zollinger-Ellison syndrome is suspected in patients with symptoms of gastric acid hypersecretion, i.e., peptic ulcer disease, malabsorption or diarrhea, or with elevated fasting serum gastrin levels. However, symptoms can be masked by the use of proton pump inhibitors and fasting serum gastrin values are not always conclusive. Therefore, the secretin stimulation test is advocated as the principal diagnostic tool to identify the Zollinger-Ellison syndrome.

#2870 When It Comes to the Diagnostic of Neuroendocrine Neoplasms (NEN), Not All Markers and Clones Were Made Equal. Assessment of 5 Makers in 466 NEN from 10 Anatomical Sites
Introduction: Histological diagnostic of neuroendocrine neoplasms (NEN) relies on morphological criteria and expression of several neuroendocrine marker assessed by immunohistochemistry. Systematic large evaluation of classical (chromogranin A (chrA), synaptophysin (Syn), CD56) and emerging (chromogranin B (chrB), INSM1) markers are lacking.

#1592 Primary Neuroendocrine Carcinoma of the Breast: A Diagnostic Approach to the Special Type of Breast Malignancy
Introduction: WHO classification from 2003 defines primary neuroendocrine carcinomas (NEC) of the breast as a group of tumors with expression of neuroendocrine markers in more than 50% of tumor cells. In the current WHO classification this category is renamed to “carcinomas with neuroendocrine features” without defined clear-cut of the percentage of tumor cells positive for neuroendocrine markers.

#231 Chromogranin A as a Predictor of Progression, Regression or Stable Disease in Ileo-Cecal Neuroendocrine Tumors
Introduction: Chromogranin A is an excellent marker for NET and tumor volume. Plasma CgA is suggested as the most reliable marker in follow-up of patients with some types of NET.

#601 Chromogranin A is a Sensitive Marker of Progression or Regression
Introduction: One of the most common is gastroenteropancreatic (GEP) NET of the pancreas, which constitute about 30% of all GEP NET. CgA is an excellent marker for NET and tumor volume and plasma CgA is suggested as the most reliable marker in follow-up of GEP but only few studies have been published.
