#2875 Immunotherapy as Second-line Treatment in Grade 3 Neuroendocrine Carcinomas: A Prospective Case Series from an ENETS Center of Excellence
Introduction: Metastatic WHO grade 3 extra-pulmonary neuroendocrine carcinomas (EP-NEC) have a poor prognosis and optimal treatment after first-line platinum-etoposide chemotherapy remains unclear. A recent, small phase II study combining ipilimumab and nivolumab showed promising results

#2772 Vitamin Supplementation and a Personalized Diet in Patients with Neuroendocrine Tumors: The DIVIT Study
Introduction: Patients with neuroendocrine tumors (NETs) are at risk for vitamin deficiencies and poor nutritional status due to excessive serotonin production, diarrhea, previous gastrointestinal surgery, and/or treatment with somatostatin analogues (SSA). Little knowledge exists about vitamin deficiency and how patients should be supported for the deficiencies they develop during their long-lasting disease.

#2957 New Evidence of Emerging Nodal Metastasis in Staging System after Surgical pNET Resection as Predictive Factor for Recurrence. Result from Monocentric Retrospective Series

#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.

#3072 Rb and p53 Status Determination by Immunochemistry Is Complementary in Routine Practice to Genetic Testing of Neuroendocrine Neoplasms
Introduction: Rb and p53 status may help distinguishing well from poorly differentiated neuroendocrine neoplasms (NEN) and may predict response to chemotherapy. Studies correlating Rb/p53 genetic and immunohistochemistry were performed on high-quality frozen samples with high throughput techniques efficient for copy number determination. This situation differs from routine practice in which small deletions may be hard to detect on formalin-fixed paraffin-embedded (FFPE) samples with a gene panel approach.

#2902 DNA Methylation Analysis of the PDX1 Gene Can Be Used for PNET Subtyping and Has a Possible Prognostic Value
Introduction: Estimating prognosis of pancreatic neuroendocrine tumor (PNET) patients remains challenging. Mutation status of DAXX/ATRX/MEN1, histone modification patterns and immunohistochemistry for relevant transcription factors, including PDX1, were recently used to perform subtyping and distinguished two main types, A and B. These subtypes are linked to cell-of-origin and associated with clinical outcome.

#3034 Somatostatin Analogs for Pancreatic Neuroendocrine Tumors: Is There Any Benefit When Ki-67 Is ≥ 10%?
Introduction: The antiproliferative effect of first-line long acting somatostatin analogs (SSA) in advanced gastro-entero-pancreatic neuroendocrine tumors (GEP-NETs) was shown in the PROMID and the CLARINET trials. Efficacy data in pancreatic NETs (PanNETs) with Ki-67 ≥ 10% are limited.

#2819 Occurrence of Pancreatic Exocrine Insufficiency in Patients with Advanced Neuroendocrine Tumours Treated with Somatostatin Analogue
Introduction: Neuroendocrine neoplasia (NENs) are heterogeneous tumours caracterized by a relatively indolent rate of growth. Usually, in G1 and G2 GEP-NENs, first-line therapy is SSAs, considering their efficacy, good safety profile, and antiproliferative effects. SSA treatment inhibits the production and excretion of pancreatic enzymes and PEI is known to be an adverse effect of SSA treatment.

#51 Epidemiology of the neuroendocrine tumors diagnosed in Cardarelli Hospital: a retrospective single-institution analysis of 274 cases
Introduction: Neuroendocrine tumors (NETs) are considered rare tumors and are characterized by their ability to produce peptides that cause typical hormonal syndromes. Neuroendocrine tumors consist of a wide spectrum of malignancies with different histology that can arise from distributed neuroendocrine cells in the body. Although these tumors are frequently indolent, they can be aggressive and resistant to therapy. Its incidence in the U.S.A has been rising in the last three decades (Surveillance, Epidemiology, and End Results registry). NETs are more common than generally believed.

#65 Deletions of 11q21-q25 are associated with atypical lung carcinoids and a poor clinical outcome
Introduction: Lung carcinoids comprise a group of smoking-unrelated neuroendocrine tumors, which can be classified in typical (TC) and atypical (AC) carcinoids. Classification is complex and its accuracy to predict disease outcome is variable. In a previous array comparative genomic hybridization (arrayCGH) study, we showed that the average number of chromosomal alterations (≥ 1Mb) was significantly higher in ACs than in TCs (512 v. 226 per tumor) and that the most common region of chromosome loss was 11q21-q25 (Neuroendocrinology 2009;90:136-137).
