#2832 Lymph Node Merkel Cell Carcinoma without Primary: Long Term Survival
Introduction: Merkel cell carcinoma (MCC) is a rare aggressive cutaneous neuroendocrine carcinoma with a high rate of metastasis. Approximately 5% of MCC are found in the lymph nodes (LNs) without a primary tumor on the skin.

#2736 Second Primary Neoplasms in Patients with Neuroendocrine Neoplasms (NEN): DATA from a Retrospective Multicentric Study
Introduction: Patients with sporadic gastro-entero-pancreatic neuroendocrine neoplasms (GEP-NEN) may exhibit a higher risk of second primary tumors than the general population.

#2835 Primary Hepatic Neuroendocrine Carcinoma: Case Report and Literature Review
Introduction: Primary hepatic neuroendocrine carcinoma (PHNEC) is an extremely rare neuroendocrine carcinoma (NEC) that originate from the liver. The diagnosis of PHNEC remains challenging because of its rarity, and its lack of unique clinical features. Available treatment options for PHNEC include surgical resection of the liver tumor(s), radiotherapy, liver transplant, transcatheter arterial chemoembolization (TACE), and administration of somatostatin analogues.

#2845 Primary Tumour Resection and PRRT of NEN Stage IV - Are There Differences in Grading?
Introduction: The resection of primary tumours (PT) in patients with stage IV NEN is still a matter of debate. The resection of tumours with a low proliferation index (G1/G2) is more accepted then the resection of high proliferative tumours (G3-NET / G3-NEC).

#2909 Serotonin-Secreting NeuroEndocrine Neoplasms of the Pancreas: Which Are the Primary Pancreatic Carcinoids?
Introduction: Serotonin-secreting pancreatic neuroendocrine neoplasms (5-HT-secreting pNENs) are very rare. They are characterised by high urinary 5-hydroxyindole-acetic acid (5-HIAA) levels (or high serum 5-HT levels).

#2841 Novelties in Primary and Metastatic GEP-NENs Clinical Outcome Investigation
Introduction: Gastro-entero-pancreatic neuroendocrine neoplasms (GEP-NENs) WHO classification, using strict cut-offs, should reflect their biological features. In real world, strict cut-offs not adequately segregate prognostic groups, in particular on metastasis (M).

#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.

#2846 Whole Genome DNA Methylation Profiling Identifies Neuroendocrine Tumor Origin
Introduction: Determining the origin of a neuroendocrine tumor (NET) of unknown primary can be challenging. Liver metastases can originate from any organ in the body, while pulmonary NETs can be metastases but also primary tumors. This especially holds true for Multiple Endocrine Neoplasia Type 1 patients, who often have multiple primary pancreatic and intestinal NETs. It is important to know the origin of the primary tumor since resection or ablation is crucial in case of treatment with curative intent. Furthermore, the site of origin determines prognosis, treatment options and eligibility for clinical trials.

#2781 Case Report: Whole Exon Sequencing of Primary Lesion and Metastatic Liver Lesion in Pancreatic Neuroendocrine Tumor
Introduction: Pancreatic neuroendocrine neoplasms(NENs) are classified into neuroendocrine tumors (NET) G1, G2, G3, and neuroendocrine carcinoma (NEC), which are different pathogenesis. The two kinds of tumors that occurs in the same lesion in one patient is very rare. We found high grade neuroendocrine neoplasms(NENG3) with a diameter of 0.1 cm in a patient with a pancreatic NETG2 (1.7 cm in diameter). The cells were significant atypia with Ki67 index of 60%, focal necrosis, while metastatic nodules in the liver (12, 0.1-1.1 cm in diameter) were all high grade NENG3.

#3031 Primitive Peripheral Neuroectodermal Tumor: Case Report
Introduction: Primitive neuroectodermal tumors belong to the family of Ewing sarcomatous tumors, all derived from the same stem cell. The cells of the neural crest are believed to be at the origin of these tumors. The predilection sites of these sarcomas are para-vertebral region, chest wall and the distal ends. The positive diagnosis of primary neuroectodermal tumors requires the contribution of histopathology, immunohistochemistry and cytogenetics.
