#2246 Diffuse Idiopathic Pulmonary Neuroendocrine Cell Hyperplasia (DIPNECH): Characterisation of Prevalence and Prognosis in the Pulmonary Carcinoid Population
Introduction: DIPNECH is considered a rare condition and the natural history is poorly described. It is thought to give rise to pulmonary carcinoids (PCs) (>5mm) or tumourlets (≤5mm).

#30 Diffuse Idiopathic Pulmonary Neuroendocrine Cell Hyperplasia
Introduction: Normal adult lungs contain scattered pulmonary neuroendocrine cells (PNEC). Reactive PNEC hyperplasia is commonly observed in persons who live at high altitude, in cigarette smokers, and in numerous lung diseases. Diffuse Idiopathic Pulmonary Neuroendocrine Cell Hyperplasia (DIPNECH) is a rare entity in which PNEC hyperplasia appears without predisposing conditions. According to the 1999 WHO lung tumor classification, DIPNECH is thought to be primarily a neuroendocrine proliferative process, which can be associated with carcinoid tumors and with a clinical picture of constrictive obliterative bronchiolitis. To date, available data regarding the treatment and the prognosis of this rare condition is limited.

#3084 Diffuse Idiopathic Pulmonary Neuroendocrine Cell Hyperplasia (DIPNECH): A Case Report and Review of Literature
Introduction: Majority of euroendocrine tumorsare found in the gastrointestinal tract and bronchopulmonary. Multifocal disease is common among patients with low-grade NET. One example of this is diffuse idiopathic pulmonary neuroendocrine cell hyperplasia. DIPNECH is an extremely rare but indolent disease with predilection for nonsmoking, middle-aged women.

#855 Extrapulmonary Small Cell Neuroendocrine Carcinoma of the Colon in an 18-Year-Old Girl
Introduction: Extrapulmonary small cell carcinoma (EPSCC) is a very rare aggressive malignant tumor typical for older age. Prognosis of EPSCC remains very poor, with three years OS 38% and five years OS less than 13%. The median survival for GI localised EPSCC is only five months. Initial extent of disease is the most sensitive prognostic factor.

#3074 Medullary Thyroid Carcinoma and DIPNECH: An Unexpected Association
Introduction: Medullary thyroid carcinoma (MTC) is a neuroendocrine tumour of the C-cells of thyroid gland. Diffuse idiopathic pulmonary neuroendocrine cells hyperplasia (DIPNECH) is a rare condition, thought to be primarily a neuroendocrine proliferative process which can develop into carcinoid tumours.

#2862 Concurrent Metastatic Pulmonary Neuroendocrine Tumor and Pituitary Macroadenoma
Introduction: The coexistence of a sellar mass in a patient with a neuroendocrine tumor, while rare, can paint the clinical picture of either a genetic syndrome, most notably multiple endocrine neoplasia syndrome type 1(MEN1) or pituitary metastasis recently more frequent probably due to the longer survival of cancer patients.

#212 Reduced MEN1 Gene Expression in Pulmonary Carcinoids Is Associated With Metastatic Disease
Introduction: Lung carcinoids are neuroendocrine tumors that can be classified as typical (TC) or atypical (AC) carcinoids. Previously, MEN-1 mutations and associated LOH of 11q13 have been implied in tumorigenesis.

#685 A Small Mixed Adenocarcinoma and Neuroendocrine Tumor of the Duodenum with Multiple Liver Metastases
Introduction: Mixed adenocarcinoma and neuroendocrine cancers (MANECs) are rare specific type of tumors that are composed of two histologic components: a neuroendocrine carcinoma and an adenocarcinoma. There are only a few reports regarding MANEC of the stomach, colon and rectum in the literature.

#2782 Clinical Efficacy of Peptide Receptor Radionuclide Therapy in Patients with Neuroendocrine Neoplasm
Introduction: Peptide receptor radionuclide therapy (PRRT) is an established treatment of metastatic neuroendocrine neoplasms (NEN) with positive effects on both progression free survival (PFS) and overall survival (OS). Only a few previous studies have investigated the effect of a second series and hence a retreatment with PRRT.

#3049 Organoid Models of Neuroendocrine Cell Growth and Tumorigenesis
Introduction: A paucity of in vitro and in vivo models has limited the study of Neuroendocrine neoplasms (NENs). Moreover, little is known about normal neuroendocrine (NE) cells and how they contribute to NEN formation.
