#2732 Prostate Metastasis of Medullary Thyroid Carcinoma in a Young Patient with MEN2B Syndrome
Introduction: Multiple Endocrine Neoplasia 2B is associated with particularly early onset medullary thyroid carcinoma (MTC). Metastatic MTC is the leading cause of early death in MEN2B. The usual sites of metastasis are neck, mediastinum, lung, liver, bone and brain.

#2813 Clinical Presentation and Prognosis of Patients with Medullary Thyroid Cancer
Introduction: Medullary thyroid carcinoma (MTC) is a rare type of tumor that originates from parafollicular C-cells and accounts for 3–4% of all malignant thyroid neoplasms. MTC presents as sporadic (75–80%) or inherited tumors (20–25%). Hereditary MTC is part of multiple endocrine neoplasia type 2 (MEN2).

#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.

#2749 Impact of Next-Generation Sequencing Analyses on Treatment Management of Patients with Advanced Neuroendocrine Neoplasms
Introduction: Molecular genomic analyses are widely used in oncology but experience in advanced neuroendocrine neoplasms (NENs) is still limited.

#3071 Hormonal Ectopic Secretion Syndromes Associated to Neuroendocine Neoplasia
Introduction: Neuroendocrine neoplasias (NEN) are able to produce and secrete bioactive peptides and cause distinct syndromes related to their biological effects. The outcome will depend on the oncological disease as well as the hormonal syndrome

#48 Preliminary report of the use of everolimus in a patient with progressive medullary thyroid carcinoma
Introduction: Medullary thyroid carcinoma (MTC) accounts for about 5-10% of all thyroid cancers, and while disease localized to the thyroid can be cured by surgery, there is no effective treatment for disseminated MTC. Constitutive activation of the RET proto-oncogene is implicated in familial and a proportion of sporadic cases, and up-regulates the AKT/PI3-kinase/mTOR signal transduction pathway. Recent studies have shown that the inhibitor of mTOR, everolimus (RAD001, Novartis, Basel), can inhibit the proliferation of the TT cell line and human MTC tumor cells in vitro. Clinically, everolimus has been shown to attenuate the progression of some gastrointestinal neuroendocrine tumors, but its clinical use in MTC has not yet been evaluated.

#79 PTOV-1 overexpression in neuroendocrine tumors: a new molecular marker
Introduction: PTOV-1 (Prostate Tumor Overexpressed-1) is a novel protein encoded by 12-exon gene localized in chromosome 19q.13.3. Recently identified as an androgen-induced gene, it is involved in prostate cell proliferation and in prostate human cancer. PTOV-1 expression has been demonstrated in neuroendocrine cells of normal prostate tissue. Preliminary data indicate that PTOV-1 can be related to flotilin, integrins and other cellular factors involved in cancer progression.

#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.

#156 Toxicity, response and survival analyses of Peptide Receptor Radionuclide Therapy (PRRT) in treatment refractory metastatic thyroid cancer using Yttrium-90 and Lutetium-177 Labeled somatostatin analogs
Introduction: Medullary thyroid carcinoma (MTC) represents about 3-16% of thyroid cancer. After first line treatment, therapeutic options for locally recurrent or metastasizing tumors include repeated surgery, whenever possible. Doxorubicin containing chemotherapy regimens in iodine-nonavid differentiated thyroid cancer have poor efficacy.

#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.
