#3053 The Splicing Machinery Is Dysregulated in Low Grade Pulmonary Neuroendocrine Tumors
Introduction: Alternative splicing dysregulation is increasingly regarded as a novel cancer hallmark influencing all key tumor features. We have shown that neuroendocrine tumors (NETs) overexpress aberrantly spliced variants of neuropeptides and receptors that increase tumor malignancy. More recently, we discovered that the splicing machinery is dysregulated in pituitary and pancreatic NETs. To date, the status of this machinery in low grade pulmonary NETs is largely unknown.

#3320 TGF-β increase caspase activation and migration in typical bronchial carcinoids
Introduction: Typical bronchial carcinoids (TBC) are well-differentiated neuroendocrine neoplasms (NEN) whose management can still be very challenging due to reduced sensitivity to therapy. Previous studies have reported TGF-β’s ability to activate mTOR pathway and induce epithelial to mesenchymal transition (EMT). Moreover, preliminary results show an overexpression of TGF-β signalling and caspase activation in TBC.

#2694 The Incidence of Gastrointestinal Neuroendocrine Tumors in the Russian Population
Introduction: Over the past four decades, the incidence of neuroendocrine tumors (NETs) has increased. The limited choice of treatments, broad clinical variability of the syndrome explains the increased interest in NETs.

#2701 Assessing the Gaps in Experience and Knowledge of Australian Primary Health Care Professionals (GPs), in Treating and Caring for the Increasing Number of Australian Neuroendocrine Tumour (NET) Patients
Introduction: Conservatively,the incidence of NETs is 7 / 000' p.a, however,the prevalence of patients living with NETs is higher,40/000',making it the 2nd most common GI malignancy after colorectal cancer.Patients are living longer,however,with impaired quality of life.Management of debilitating symptoms such as diarrhoea,fatigue,anxiety,and flushing are complex and heterogenous.

#2733 Pancreatic Metastases Originating from Intestinal Neuroendocrine Tumours
Introduction: Pancreatic metastases are rare, accounting for 1 to 2% of pancreatic tumours. Data on pancreatic metastases of intestinal NETs are lacking.

#2820 Efficacy of Peptide Receptor Radionuclide Therapy for Esthesioneuroblastoma
Introduction: Esthesioneuroblastoma (ENB) is a rare malignancy with limited therapeutic options when unresectable or metastatic. The overexpression of cell-surface somatostatin receptors in ENB is a potential molecular target making it amenable to peptide receptor radionuclide therapy (PRRT). High-level evidence supporting PRRT has been published for unresectable gastroenteropancreatic neuroendocrine tumours; however, data is limited for PRRT efficacy for ENB.

#2972 Characteristics and Management of Paragangliomas, 10 Years Experience
Introduction: Paraganglioma (PG) is a rare extra-adrenal neuroendocrine tumor, with common sites of presentation being abdomen, and head and neck region. The majority of PGs appear to be sporadic. However, almost half of cases are associated with an inherited syndrome. The highest malignancy rates are seen in paragangliomas (PGs) associated with SDHB mutations, which are usually abdominal and secretory.

#3015 Biopsy Specimen Diagnosis in Pulmonary Carcinoids, A Shot in the Dark
Introduction: Pulmonary carcinoids (PCs) are rare well-differentiated neuroendocrine tumors, which can be separated into typical carcinoid (TC) and atypical carcinoid (AC). Advised treatment for local carcinoid disease is surgical resection using lobectomy, while parenchymal saving strategies such as sub-lobar or endobronchial resection might be considered for TC. In general, pre-operative diagnosis using a (transbronchial/transthoracic) biopsy sample is performed to demonstrate malignancy. However, TC and AC classification can solely be performed on surgical resection specimens, which may challenge pre-operative treatment decisions.

#3026 IMP3 and Ki-67-Factors of Poor Clinical Outcome in Neuroendocrine Tumors of the Lung
Introduction: Insulin- like growth factor-II messenger RNA- binding protein- 3 (IMP3) is often detected in malignant neoplasm of different sites. Ki-67 proliferative index, although helpful in diagnosing neuroendocrine tumours of lung, has not been recognised as prognostic factor.
