#934 Neuroendocrine Tumors of The Appendix: A Study of Presentation, Investigation and Management
Introduction: Causes of appendicitis include infection, inflammatory bowel disease, faecoliths and neoplasm. Rarer causes of obstruction, such as neoplasm, may present in an identical manner to common causes, such as infection, and remain undiagnosed without histologcal analysis of appendicaecal tissue. Neuroendocrine tumors of the appendix are most commonly detected incidentally by histological analysis of appendicaecal tissue following appendicectomy.

#126 Assessment of the proliferation marker Ki-67 by endoscopic ultrasound guided-Fine Needle Aspiration (EUS-FNA) in pancreatic endocrine tumors: A comparative analysis with histology of the surgical specimen
Introduction: Assessment of the proliferative index by Ki-67 immuno-labelling is an important prognostic parameter for the biologic behavior of digestive neuroendocrine tumors, usually established on the histological specimen obtained after surgery or macro-biopsy. However, small pancreatic endocrine tumors (PET) are more and more often recognized by CT/MRI and diagnosed by EUS. The value of Ki-67 labelling index (Ki-67-LI) on fine needle aspiration (FNA) is not well-established in this setting, although regularly assessed.

#253 Description and Treatment of GEP NETs in a Spanish Hospital During 10 Years
Introduction: In our area the GEP NET incidence is similar to that of gastric and exocrine pancreatic cancers consequently being important to know their characteristics and the most convenient therapeutic approach.

#863 Assessment of Neuroendocrine Tumors' Heterogeneity with Combination of Molecular Imaging Studies
Introduction: Neuroendocrine tumors (NET) are heterogeneous neoplasms. The choice of the appropriate molecular imaging study for assessment of disease extent usually depends on tumor grade.

#2272 Enhancing Diagnostic Precision Through Combined Genomic and Histopathological Analysis of Pancreatic Neuroendocrine Tumors
Introduction: Diagnostic differentiation of uncommon pancreatic malignancies can be challenging, but is essential for accurate clinical management; genomic analysis may provide a tool for making this critical distinction.

#884 Simultanenous Duplicate Malignant Disease-Adenocarcinoma of the Colon and Disseminated Neuroendocrine Tumor
Introduction: Fifty-nine-year old man, under examination due to weight loss, enterorrhagia, general abdominal discomfort. Endoscopy detected tumorous infiltration 20 cm from the anus, bleeding. Histology: adenocarcinoma. CT abdomen detected liver lesion. The lesion was hypervascularized, and the CT picture was atypical for metastatic adenocarcinoma. CT chest: tumor lesion in the left lower segment, metastatic LN in mediastinum. According to the CT, the picture is atypical for metastases.

#1344 Reassessment of Proliferative Activity at Disease Progression in Neuroendocrine Neoplasms
Introduction: Ki67 is a key factor influencing prognosis and treatment in NENs. However, whether repeating histology at time of progression of disease (PD) is debated

#1889 FNA Under Percutaneous Ultrasound or Endoscopic Ultrasound for Pre-Operative Diagnosis and Grading Determination in PanNET. Are They Reliable to Define a Tailored Therapy?
Introduction: Fine-needle aspiration cytology (FNA)under percutaneous ultrasound guided (pUS)or endoscopic ultrasound(EUS)control is a minimally invasive technique allowing diagnosis and grading determination in pancreatic neuroendocrine tumors (PanNET).Obtaining a correct cytological diagnosis is crucial for a tailored therapy

#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.

#114 Downstaging of a gastroenteropancreatic neuroendocrine tumor after combination therapy of temozolomide, Bevacizumab and long-acting somatostatin analogs
Introduction: Patients with gastroenteropancreatic endocrine (GEP) tumors and progressive disease have been treated with several chemotherapeutic regimens with variable responses and considerable toxicity. Recent studies have shown that GEP tumors may respond to therapy with anti-angiogenic agents, mainly as a result of their increased vascularity.
