#492 Should Primary Hyperparathyroidism at Age Below 40 Years Always Lead to Search for MEN-1, Despite Presence of Other Plausible Explanations?
Introduction: A 30-year-old female patient with inherited osteogenesis imperfecta (OI) Type 1 was referred due to hypercalcaemia and suspicion of primary hyperparathyroidism (pHPT). She had serum ca2+ 1.56 mmol/L, serum parathyroid hormone 115 ng/ml (< 70), and pHPT was diagnosed, but no scan uptake. By exploratory neck surgery, all parathyroid glands were hyperplastic and 3 ½ parathyroid + thymus were removed. The HPT was hypothesised to be due to abnormal calcium metabolism from OI (J Endocrinol Invest 1999), although not described previously.

#838 Succinate Dehydrogenase Subunit B (SDHB) Immunohistochemistry Should Not Replace Clinical Genetic Testing for SDHx Mutations in Patients with Pheochromocytoma and Paraganglioma
Introduction: Mutations in any of the subunits of the succinate dehydrogenase (SDH) complex predispose to PCC/PGL. Knowing the germline mutation is important for surveillance for recurrence, metastatic disease or more primary tumors and for screening affected family members. Expression of SDHB protein by immunohistochemistry (IHC) has been proposed as a surrogate marker for SDHx mutation status, with absent or decreased expression of SDHB suggesting the presence of a germline SDHB mutation or disruption of the SDH complex by mutation in another subunit.

#1600 Should Surgery Be Conducted for Small Nonfunctioning Pancreatic Neuroendocrine Tumors: A Systemic Review
Introduction: Researches showed controversial results regarding whether surgery should be conducted for nonfunctioning pancreatic neuroendocrine tumors (PNETS) smaller than 2 cm. Both the ENETS and NCCN guidelines recommended observation for selected cases, while none of them pointed out which cases should be chosen.

#1699 Should the Selective Arterial Secretagogue Injection Test for Insulinoma Localization be Evaluated at 60 Seconds or At 120 Seconds?
Introduction: The selective arterial secretagogue injection (SASI) test is considered indispensable for an accurate insulinoma localization. The optimal timing of post-injection evaluation has not been established yet, as some studies recommend 60 seconds [SASI (60 sec)] while others support 120 seconds [SASI (120 sec)].

#2248 High Grade (G3) Gastro-Entero-Pancreatic Neuroendocrine Neoplasms: Should the New WHO Classification Apply to All?
Introduction: Grade 3 (G3) neuroendocrine neoplasms (NEN), arising from the gastro-entero-pancreatic system (GEP), are classified according to WHO 2010 and defined as having a Ki67 of > 20%. However this groups together G3 well differentiated neuroendocrine tumours (WD-NET) with poorly differentiated neuroendocrine carcinomas (PD-NEC). Recently, WHO have proposed a new classification for pancreatic NEN, with sub-division into G3 WD-NET and G3 PD-NEC

#902 Chemotherapy for Advanced Neuroendocrine Tumors (NETs): Patient Selection Should be Independent of Primary Tumor Site
Introduction: Chemotherapy (CT) is used to treat patients (pts) with advanced poorly-differentiated (Pd); or well-differentiated (Wd) NETs with high-tumor burden (usually of pancreatic (pNET) origin).

#920 High Grade (G3) Neuroendocrine Neoplasms Should Be Further Classified According to Morphological Differentiation
Introduction: Neuroendocrine neoplasms (NENs) with a Ki-67 >20% (Grade 3) are classified together as Neuroendocrine Carcinomas (NEC), and are usually considered as poorly differentiated. However Grade (G)3 NENs may be heterogeneous, with some demonstrating a well-differentiated cell morphology.

#1392 How Long Should We Look Up for Recurrence After Resection of Pancreatic Neuroendocrine Tumors?
Introduction: There remains several unsolved issues to be settled about the management of pancreatic neuroendocrine tumors (PNETs) after resection. One of these problems are the follow up period after a complete resection of the tumor.

#1402 Merkel Cell Carcinoma of Lymph Node Without Skin Primary Can - and Should - Be Distinguished from Others Metastatic Neuroendocrine Carcinoma
Introduction: Merkel cell carcinoma of lymph node without primary tumour (MCCNWP) is a rare tumour which can be misinterpreted as lymph node metastasis (LNM) from a high-grade neuroendocrine carcinoma (NEC) on histological examination. However, this distinction is crucial for therapeutic management.

#148 Near-complete regression of liver metastatic lesions in a patient with advanced pancreatic gastrinoma in response to somatostatin analogue therapy following cytoreductive surgery
Introduction: Although the majority of pancreatic NETs present with hepatic metastases, surgery with curative intent should be the first consideration. Cytoreductive surgery by resection of primary and secondary deposits may be of value in achieving local or endocrine symptoms control.
