#2712 HORMONET: Study of Tamoxifen in Well Differentiated Neuroendocrine Tumors (NET) and Hormone Receptor Positive Expression
Introduction: We have shown immunohistochemistry (IHC) expression of estrogen (ER) and progesterone receptors (PR) in 20.8% and 18.8% of 96 NET patients (pts). An old clinical trial (Mortel C, 1984) suggested antitumor effects of estrogen/progesterone-directed therapies in NET. Yet the effects of an antiestrogen agent in NET pts whose tumor express ER and/or PR are unknown.

#80 Metastatic growth hormone secreting pituitary carcinoma treated with peptide receptor radionuclide therapy
Introduction: Pituitary carcinoma (PC) is an extremely rare condition defined by the presence of adenohypophyseal neoplastic tissue outside the pituitary. Clinical experience regarding diagnosis, management and prognosis of PC is very limited. Growth hormone (GH) secreting PC is even rarer and represents a particular challenge to clinical practice. Therapeutic modalities utilized to treat PC include surgery, radiation, hormonal therapy, and cytotoxic drugs. Peptide Receptor Radionuclide Therapy (PRRT) is an emerging therapeutic modality that involves the targeted delivery of an ablative dose of radiolabelled somatostatin analog. PRRT has been applied to various neuroendocrine tumors and results in prolonged survival and enhanced quality of life. As yet, this therapy has not been applied to malignant pituitary tumors.

#86 Structure of complications in acromegalic patients at a single institute
Introduction: Acromegaly leads to reduced life expectancy, with an increase in the mortality rate. From several retrospective cohort studies, the predominant outcome is serum growth hormone (GH) concentration. Other factors associated with increased mortality include duration of symptoms prior to diagnosis, duration of disease, older age at diagnosis and the presence of cardiovascular disease, diabetes mellitus (DM) and hypertension at diagnosis.

#140 Serotonin expression in gastric neuroendocrine tumors and in foci of endocrine cell hyperplasia
Introduction: The most abundant neuroendocrine (NE) cell population of the human oxyntic mucosa is the enterochromaffin-like (ECL) cells, followed by ghrelin, somatostatin and serotonin cells, respectively. All types of ECL cell carcinoids (ECL-CCs) contain serotonin cells but in a varying frequency. Hitherto, only foci of ECL and ghrelin cell hyperplasia have been described in the peritumorous mucosa of types I and II ECL-CCs. It is established that hypergastrinaemia can cause ECL cell hyperplasia but it does not affect serotonin cells. The vesicular monoamine transporter 2 (VMAT 2) is used as an immunohistochemical marker for ECL cells.

#532 Effect of the Combined Administration of mTOR Inhibitor and Dopamine or Somatostatin Analogues in a Human Bronchial Neuroendocrine Cell Line
Introduction: The mTOR inhibitor rapamycin (RAP) has been considered an anticancer agent. The role of dopamine and somatostatin in controlling cell secretion and proliferation in neuroendocrine tumors (NETs) is still unclear.

#917 The Second Non-Metastatic Tumor in Romanian Patients with NETs
Introduction: NETs involve aggressive evolution as progression of primary tumor. Some cases associate a second apparently non-related tumor.

#1638 3D Primary Cell Culture: A New Promising Preclinical Model for Pancreatic Neuro-Endocrine Tumors (pNETs).
Introduction: The lack of adequate in vitro and in vivo preclinical models has hampered the identification of novel treatment options and the development of personalized therapy selection for pNET patients.

#1914 Prognostic Factors for Long-Term Survival in 102 Consecutive Pancreatic Resections for Primary Neuroendocrine Tumor
Introduction: Neuroendocrine tumors (NET) of the pancreas represent a rare entity of primary pancreatic tumors. However, with the continuous progress in modern diagnostics NET`s are increasingly detected and prognostic factors are being reevaluated to establish personalized treatment concepts.

#2087 Prospective, Multi-Center, Open Label, Phase Study II of APOC, a New Controlled Release 15mg Octreotide Acetate, for the Treatment of Advanced NETs
Introduction: Somatostatin analogues (SSAs) are the cornerstone of systemic therapy of advanced NETs. The efficacy controlling hormone release and tumor growth together with the favorable toxicity profile have positioned SSAs as upfront therapy. Despite of second-line therapies including targeted agents, chemotherapy and radiolabeled peptides have demonstrated activity controlling tumor growth, the less favorable toxicity profiles become a usual discussion with patients (pts) to preserve the quality of life (QoL). Additionally, from concordant flow of evidences clinical benefits could be obtained with higher SSAs circulating levels but remain unreachable with current products. APOC is a new controlled release ready-to-use convenient therapeutic, designed to cover specifically these clinical unmet needs.

#2156 Two Cases Synchronous Atypical Parathyroid Adenomas and Papillary Thyroid Carcinoma
Introduction: A literature review revealed a prevalence of approximately 3% of nonmedullary thyroid cancer, which was found in patients operated on for primary hyperparathyroidism (pHPT). Papillary thyroid carcinomas(PTC) is a malignant epithelial tumour. PTC represent up to 87% of all thyroid carcinomas. Atypical parathyroid adenoma(APA) are a subset of parathyroid neoplasms that exhibit some of the features of parathyroid carcinoma but lack unequivocal invasive growth. APA represents about 0,5-4% of cases of pHPT. As a group, they may be considered tumors of uncertain malignant potential.
