#975 Electron Microscopy of Pancreatic Beta Cell Neuroendocrine Tumors (NETs) in Multiple Endocrine Neoplasia Type 1 (MEN1) Knockout Mice Reveal an Adenomatous Phenotype with Depletion of Insulin Granules and Increased Mitochondrial Content
Introduction: Insulinomas are ╬▓ cell neuroendocrine tumors (NETs) that secrete insulin, and ~4% of insulinoma patients have multiple endocrine neoplasia type 1 (MEN1). One in ten MEN1 patients present with an insulinoma. Previous reports describe insulinomas as possibly having typical granules (46.4%) or atypical smaller granules (34.3%), both associated with adenomas, or agranular cells (14.3%) associated with carcinomas. MEN1 knockout (Men1+/-) mice develop pancreatic NETs that are mostly insulinomas, and their ultrastructural phenotype is unknown. We hypothesized that these may resemble the adenoma phenotype with atypical granules.

#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.

#263 Chronic Atrophic Gastritis Associated with Hyperparathyroidism: A prospective Study
Introduction: The association of gastric carcinoids (GCs) type 1 and hyperparathyroidism (HPTH) has been reported, whereas a possible association between chronic atrophic gastritis (CAG) and HPTH is still scant.

#272 Plasma Chromogranin A in Patients with MEN I and Pancreatic Endocrine Tumors
Introduction: Circulating chromogranin A(CgA) is considered a useful marker for gastroenteropancreatic endocrine tumors. Data on its pattern in MEN-1 patients with non-functioning pancreatic tumors(NFPT) are scant.

#295 Unusual Behavior of Gastric Carcinoid Type 1
Introduction: Gastric carcinoids (GC) are rare tumors of the stomach. GC type 1 are associated with chronic atrophic gastritis (CAG) and are the most benign type, having low metastatic potential.

#305 Risk Stratification Using Octreotide Test for Patients with Gastroenteropancreatic Neuroendocrine Tumors: Results of Prospective Validation of the Test
Introduction: We recently demonstrated that a plasma CgA decrement >30% after octreotide s.c. injection is a simple criterion for treatment with Somatostatin analogues (SSA) of gastroenteropancreatic endocrine tumors.

#349 Gastrointestinal Stromal Tumor (GIST) Of The Esophagus In A Patient With MEN-1 And-Related Pancreatic Gastrinoma
Introduction: Both Multiple Endocrine Neoplasia type 1 (MEN-1; OMIM #613733)-related-gastrinomas and Gastrointestinal Stromal Tumors (GISTs; OMIM #606764) are rare neoplasms and their association has been rarely reported so far.

#354 Risk Stratification Using Octreotide Test For Patients With Gastro-Entero-Pancreatic Neuroendocrine Tumors: Results Of Prospective Validation Of The Test
Introduction: Criteria for treatment with somatostatin analogs (SSAs) of gastroenteropancreatic neuroendocrine tumors (GEP-NETs) are presence of somatostatin receptors, a positive Octreoscan® or hormonal decrement >50% after octreotide s.c. injection (octreotide test, OT). We demonstrated that a plasma CgA decrement >/=30% after OT is a selection criterion able to predict the clinical response to SSAs.

#418 Chromogranin A (CgA) in the Diagnosis and Monitoring of Patients with Gastroenteropancreatic (GEP) Neuroendocrine Tumors (NET): A Single-Institution Experience
Introduction: Gastroenteropancreatic neuroendocrine tumors (GEP NET) are heterogeneous neoplasms with different malignancy. Plasma chromogranin A (CgA) may play an important role in predicting outcome.
