#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.

#88 EpCam expression and detection of circulating tumor cells in neuroendocrine tumors
Introduction: Using the CellSearchTM system, circulating tumor cells (CTCs) can be reproducibly enumerated according to expression of EpCAM and cytokeratins 8, 18 or 19 and the absence of the haemopoietic marker CD45. The number of CTCs detected in 7.5 mls blood has been shown to correlate with prognosis in breast, colon and prostate cancer and can predict response to therapy. Neuroendocrine tumors (NETs) have not previously been reported to express EpCAM and have not been systematically assessed for presence of CTCs. We have therefore explored the expression of EpCAM in NETs and the detection of NET cells in the circulation.

#90 The prognostic value of FDG-PET scan in neuroendocrine tumors: a retrospective analysis of 46 patients treated in one center
Introduction: Neuroendocrine tumors (NETs) are rare and generally indolent. For diagnostic purposes, the sensitivity of FDG-PET scan is known to be low in this setting, though when positive, its prognostic value is not well-defined in NET.

#141 Incidence of second primary tumors in patients with neuroendocrine tumors
Introduction: Based on epidemiological data from SEER 1950-1999, 22.4% cases of non-carcinoid second primary tumors have been described in patients diagnosed with neuroendocrine tumors. The incidence of this type of tumors varies, depending on the series assessed.

#194 Pancreatic Neuroendocrine Tumors: Experience of Endocrinology Department of the University Hospital of Coimbra
Introduction: Pancreatic neuroendocrine tumors (PNETs) are uncommon neoplasms, comprising 1-2% of all pancreatic tumors. The majority are nonfunctional. Of the functional tumors, insulinomas are the most common.

#397 Swiss Neuroendocrine Tumor (SwissNET) Registry: Update After Three Years
Introduction: To improve epidemiological data on patients with neuroendocrine tumors (NETs) in Switzerland, the Swiss registry for NETs (SwissNET) was established in 2008. Here we present the current state of the registry in 2011.

#544 Second Primary Tumor in Patients with Gastroenteropancreatic Neuroendocrine Tumors (GEPNETs): Data From a Retrospective Observational Unicentric Study
Introduction: It is known that GEPNETs are associated with a high incidence of second primary tumors, especially in the context of inherited syndromes and synchronous injuries to the intestine.
