#2976 Incidence of Appendiceal NEN and Adherence to Pathological Classification Rules and Treatment Guidelines: Results of the Population Based Cancer Registry in Belgium
Introduction: Classification of appendiceal neuroendocrine neoplasms (aNEN) changed significantly over the years and treatment algorithm remains a matter of debate.

#2965 Molecular Signature of Rectal Neuroendocrine Neoplasia
Introduction: Rectal neuroendocrine tumors are rare neuroendocrine neoplasias (NEN). Little is known about prevalence and type of somatostatin receptor subtypes (sstr) expression and somatic mutations in relation to long-term clinical outcome.

#2804 Claudin-18 Is a Sensitive and a Specific Marker for Gastric Neuroendocrine Tumors
Introduction: Antibody-based cancer therapies are emerging as promising therapeutics in oncology, including one in clinical trials that targets claudin-18, a protein expressed in normal gastric epithelium and some gastric adenocarcinoma. We currently have no markers for gastric well-differentiated neuroendocrine tumors (NETs).

#2836 Prospective Evaluation of the NETest as a Liquid Biopsy for Gastroenteropancreatic and Bronchopulmonary Neuroendocrine Neoplasms: ENETS Center of Excellence Experience
Introduction: There is a substantial clinical unmet need for an accurate blood biomarker for neuroendocrine neoplasms (NENs).

#2927 Systemic Chemotherapy for Inoperable Goblet Cell Adenocarcinomas (GCAs) and the Role of Anti-EGFR Antibodies
Introduction: Appendiceal GCAs (previously Goblet Cell Carcinoids) have variable behaviour. Systemic chemotherapy (Chemo) is often extrapolated from colon cancer. KRAS mutations (KRAS-mut) are rare and more often present in Tang-C/high grade. The role of anti-EGFR antibodies (MoAb) is unknown.

#2953 Temporal Trends in Incidence, Presentation and Work-Up of Neuroendocrine Neoplasms of the Appendix
Introduction: Although temporal trends in incidence and prognosis of neuroendocrine neoplasms have been described in the literature, data regarding trends in Appendiceal Neuroendocrine Neoplasms (ANENs) is limited.

#3005 Comparison between Tang and WHO 5th Edition Grade Classification for Goblet Cell Adenocarcinomas
Introduction: Appendiceal GCAs (previously Goblet Cell Carcinoids) are composed of cells with secretory phenotypes. Several grading systems to predict behaviour are available (e.g.Tang). The latest WHO 5th edition adopted a grading system similar to colon adenocarcinomas.

#47 Plasma CCN2/connective tissue growth factor is associated with right ventricular dysfunction in Patients with Neuroendocrine Tumors
Introduction: Carcinoid heart disease (CHD) is a known complication of neuroendocrine tumors (NETs), particularly of those arising from the small intestine, appendix and proximal colon (previously known as mid-gut carcinoids). CHD is characterized by right heart fibrotic lesions and has traditionally been defined by the degree of valvular involvement, most commonly in the form of tricuspid regurgitation. Right ventricular (RV) dysfunction due to mural involvement may also be a manifestation. Connective tissue growth factor (CCN2) is upregulated in many fibrotic disorders. Increased tumor expression of CCN2 has been shown in patients with small intestinal NETs associated with peritoneal fibrosis. At present, its role in carcinoid heart disease is unknown.

#70 The validity of Ki-67 as a prognostic indicator in patients with appendiceal carcinoid tumor
Introduction: Carcinoid tumors of the appendix are rare and often discovered incidentally through appendectomy. Most are clinically benign but may be associated with metastatic disease. Ki-67, a nuclear protein structurally associated with chromatin, is an excellent marker for measuring cell proliferation and it has been shown to correlate with the outcome in pancreatic and ileocecal carcinoids.

#117 Synchronous appendiceal neuroendocrine carcinoma and mucinous cystadenocarcinoma: a case report
Introduction: Appendiceal tumors with histological features of both carcinoids and adenocarcinomas are very rare. Carcinomas of the appendix are usually mucinous adenocarcinomas with a tendency to produce peritoneal pseudomyxoma and without metastatic spread until late in the disease course. Carcinoid tumors of the appendix are a common incidental finding.
