#2213 Imaging Modality Depending on the Levels of Tumor Markers
Introduction: 18 F-Fluorodihydroxyphenylalanine(18F)-FDOPA positron emission tomography (PET)/computed tomography (CT) has the advantage of being a noninvasive test and is by far the most promising imaging modality for neuroendocrine tumors (NETs).

#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.

#442 Low Diagnostic Accuracy of Tumor Markers for the Annual Screening of Pancreatic Neuroendocrine Tumors in MEN-1 Patients
Introduction: The use of tumor markers for annual screening for pancreatic neuroendocrine tumors (pNET) in Multiple Endocrine Neoplasia type 1 (MEN-1) is debatable because of low-level evidence and high costs.

#2279 Expression of FOXM1 in G3 Neuroendocrine Tumors (NET G3) and G3 Neuroendocrine Carcinomas (NEC G3) of the Pancreas and the Intestine
Introduction: G3 gastroenteropancreatic neuroendocrine tumors (G3 NET) and carcinomas (G3 NEC) differ considerably concerning their biological behavior and patients outcome. Whereas the WHO2017 classification for pancreatic NETs proposes a distinction of both groups using the Ki-67 proliferation marker (Klöppel et al. Reviews and Reports 2017), a useful marker for the subclassification of G3 intestinal NETs have not been recommended until now.

#994 Predictive Biomarkers of Response in Patients with Extrapulmonary Neuroendocrine Tumors (EPNET) Treated with Platin-based Chemotherapy
Introduction: EPNET, particularly advanced and Grade 3 (G3) tumors are often treated with chemotherapy. While many patients experience tumor response, those rarely live for more than two years. Predictive markers could potentially help us to tailor the best treatment for these patients (pts).

#2197 Tumor Necrosis of Primary Malignancy Affects Survival and Outcome in Patients with Liver Metastases from Neuroendocrine Tumors
Introduction: Reliable biomarkers represent a crucial unmet need in the management of neuroendocrine tumors. Tumor necrosis has been suggested to have a prognostic value in selected solid tumors but is not included in established WHO NET Grading Systems. However, little is known regarding the influence of tumor necrosis on tumor progression and prognosis in patients with liver metastasis from neuroendocrine tumors.

#804 The Plasma Chromogranin A Level Predicts Survival and Tumor Response in Patients with Gastroenteropancreatic Neuroendocrine Tumors
Introduction: The plasma chromogranin A (CgA) level is a reliable biomarker for identifying patients with advanced gastroenteropancreatic neuroendocrine tumors (GEP-NETs).
