#2767 Rectal NETs and Rectosigmoid Junction NETs May Need to Be Treated Differently
Introduction: Neuroendocrine tumours (NETs) are heterogeneous, and the incidence of colorectal NETs is rapidly increasing.

#2797 Assessment of Quality of Life in Patients with Neuroendocrine Tumours: Results of a Systematic Literature Review
Introduction: Health related quality of life (HRQoL) is increasingly important as a concept reflecting the patients’ perspective in conjunction with the disease presentation severity and treatment. Understanding the impact of treatment on neuroendocrine tumour (NET) patients’ HRQoL is paramount given the nature of the disease.

#9 Case Management of Metastatic carcinoid of the Foregut,Midgut and Hindgut:the relevance of Ki-67 prognostication
Introduction: The predictive value of tumor grade in the prognosis of carcinoid is insufficient and somehow misleading. The grade and differentiation in carcinoid tumors must be seen in conjunction with the Ki-67 index. The Ki-67 protein is a cellular marker for proliferation, present during all active phases of the cell cycle (G1, S, G2 and mitosis) and absent from resting cells (G0). It is therefore an excellent marker to determine the growth fraction of a given cell population. The Ki-67 labelling index is often correlated with the clinical course of carcinoid.

#22 A Case Illustrative of Phenotypic Heterogeneity and Challenges in the Management of Paraganglioma
Introduction: Paragangliomas (PGLs) are extra-adrenal, usually benign, highly vascularized tumors that originate from neural-crest-derived chromaffin cells. These tumors are subdivided as either sympathetic or parasympathetic, depending on their location and catecholamine production. Sympathetic PGLs are situated along the abdominal sympathetic trunk and usually produce catecholamines, whereas parasympathetic PGLs are located in the head and neck, and these usually do not produce catecholamines. PGLs may present as sporadic or inherited tumor syndrome, including MEN 2, with RET germline mutations, von Hippel-Lindau (VHL) disease due to germline mutations in VHL gene, and pheochromocytoma-PGL syndrome. The latter is frequently a hereditary condition and is caused by germline mutations in the SDHB, SDHC, or SDHC genes. Patients with familial PGLs may present at a younger age, often as multifocal tumors, with an increased risk of recurrence and a higher frequency of malignancy in those with SDHB mutations. SDH mutations induce angiogenesis and tumorogenesis through the inhibition of hypoxia-inducible factors (HIF)-propyl hyroxylase. A younger age at onset, malignancy, and a positive family history are clinical parameters of high specificity, but low sensitivity for diagnosis. Genetic analysis for mutations in SDH genes for the patient and family members, and surveillance for the affected patient and family members, are necessary where there are no clear clinical or family indicators for the syndrome. We present a case of a large abdominal malignant PGL in a 20-year-old pt. that went on without clinical detection for at least three years.

#39 Specialist dietetic input and nutritional outcomes in Neuroendocrine Tumour Patients
Introduction: Neuroendocrine tumors (NETs) are a heterogeneous group of tumors that are complex to manage and require a multidisciplinary approach. The most common primary sites are the small intestine and pancreas. The disease itself, as well as sequelae from surgery and medical therapy, can have a negative impact on patients’ nutritional status. Weight loss is known to be a poor prognostic indicator.

#134 Gastrointestinal neuroendocrine tumors: tumor characteristics and long-term clinical outcome in the German NET registry
Introduction: Prognosis of neuroendocrine tumors (NETs) has been difficult to predict due to heterogenous tumor biology, various classification systems, and lack of reliable and recent data due to the rarity of these tumors.

#271 A Novel Missense Mutation of the TMEM127 Gene that Leads to Pheochromocytoma Phenotype
Introduction: Recently, truncating germline mutations in TMEM127 gene have been identified in 30% of familial cases of adrenal pheochromocytoma (PHEO) and in 3% of apparently sporadic cases.

#357 Alternative Splicing and Differential Gene Expression in Pancreatic NETs
Introduction: Alternative splicing is an important mechanism to increase diversity of the proteome in higher organisms. These protein isoforms can provide as a selective drug target or marker for cancer diagnosis.
We present here a new DNA array that allows identification of splice variation and differential expression of 357 G protein-coupled receptors (GPCR) and 11 proteins of the extracellular matrix.

#363 Clinicopathological characteristics are capable of predicting long-term outcome of gastrointestinal neuroendocrine tumours in Germany
Introduction: Neuroendocrine tumours (NET) are a rare and heterogeneous group of neoplasm. Throughout the last decades the classification of NET has been both difficult and incoherent. Therefore making prognostic straticifation often difficult.
