#40 Clinical and prognostic implications of the genetic diagnosis of hereditary NET syndromes in asymptomatic patients
Introduction: Neuroendocrine tumors (NETs) are rare neoplasms, heterogeneous, and with variable biological behavior. NETs can be sporadic or they can arise in complex endocrine hereditary syndromes such as Multiple Endocrine Neoplasias (MEN), Familial Paragangliomatosis (FPGL), Neurofibromatosis type 1 (NF1), von Hippel-Lindau Disease (VHL), Tuberous Sclerosis (TSC) and Carney Complex (CC). By performing genetic screening, patients with hereditary NETs can be identified before the development of tumors.

#76 Role of contrast-enhanced ultrasonography in the differential diagnosis of the pancreatic and hepatic lesions
Introduction: Contrast-enhanced ultrasonography (CEUS) is a new promising tool for the characterization of pancreatic lesions. This technique allows for highlighting the micro-vascularization of a lesion, especially with the use of second generation contrast media, characterized by harmonic responses at low acoustic pressures. Pancreatic endocrine tumors (PET)s were reported to have a peculiar behavior at CEUS, consisting of a higher enhancement compared to normal pancreas in the arterial phase and a rapid washout.

#108 Everolimus (RAD001) induces tumor response in patients with medullary thyroid cancer: an in vivo and in vitro study
Introduction: Medullary thyroid cancer (MTC) is a neuroendocrine tumor (NET) of the thyroid C cells which is known to express somatostatin receptors. Octreotide, a somatostatin analogue exerting both antisecretory and antitumor activity in different types of NETs, has shown low efficacy in MTC. Everolimus (RAD001), an inhibitor of mTOR, has shown antitumor effects in patients with NETs and synergistic effects when combined with octreotide. Until recently, RAD001 has never been evaluated in MTC.

#160 The role of T-type calcium channels in medullary thyroid carcinoma (MTC): T-type calcium channel blockers inhibit hormone secretion and induce apoptotic cell death in a human MTC cell line
Introduction: Medullary thyroid carcinoma (MTC) accounts for approximately 5-10% of thyroid cancers. In the case of tumors limited to the thyroid gland, the prognosis is generally favorable, whereas 5-year survival averages only 40% in patients with metastatic disease. In these patients, conventional chemotherapy only occasionally leads to a complete response and partial responses are observed in less than 30% of the cases. Therefore, intense efforts are currently directed toward the identification of new druggable targets for the treatment of this devastating disease.

#274 An Unexpected Diagnosis
Introduction: Paragangliomas (PGL) are defined as rare tumors arising from extra-adrenal sympathetic and parasympathetic paraganglia and malignant paragangliomas are defined by the presence of metastases.

#286 Aberrant Expression of FSH Receptor in Pancreatic Neuroendocrine Tumors
Introduction: FSH receptor (FSHR) expression is restricted to gonads. FSHR plays an important role in regulation of ovarian angiogenesis. Recently, FHSR expression has been shown in blood vessels of various tumors.

#498 Limitations of Chromogranin A in Clinical Practice
Introduction: Chromogranin-A (CgA) is the most accurate marker for the histological diagnosis of neuroendocrine tumors (NETs). However diagnostic usefulness of circulating CgA is controversial as several conditions, both neoplastic and non-neoplastic, may induce false positive increases of this marker.

#518 CK19 and KIT Immunostaining is a Useful Adjunct to Ki-67-Based Grading of Pancreatic NET: A Study on Matched Cytological and Histological Samples
Introduction: Pancreatic neuroendocrine tumors (NET) are rare neoplasms. Recent evidence suggests that Ki-67 staining predicts their behavior. Even more recently, a prognostic role has been proposed also for CK19 and KIT. This panel might guide patient management. CK19 and KIT have not yet been evaluated on NET on Fine needle aspiration samples (FNAs).

#524 Sunitinib in a MEN-1 Patient with Small Cell Neuroendocrine Tumor of the Thymus
Introduction: MEN-1 is an autosomal dominant disease caused by mutation of the oncosuppressor gene menin. MEN-1 is typically associated with hyperparathyroidism, islet cell tumors and pituitary adenomas, but it can also be associated with other neoplasms, such as thymic carcinoids.
