#2018 Ex Vivo Activity of Cytotoxic Drugs and Targeted Agents in Small Intestinal Neuroendocrine Tumors
Introduction: Small Intestinal Neuroendocrine Tumours (SI-NETs) are considered to be generally resistant to systemic treatment. To date predictive markers for drug activity are lacking.

#2271 Effects of Multi-Receptor Targeting Drugs in Neuroendocrine Tumors Using 3D Cell Culture
Introduction: Symptom control in functioning neuroendocrine tumors(NETs) may be difficult in some cases, thus, new therapeutic options, including multi-receptor targeting drugs are required.

#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.

#629 Targeting Chaperone Activity and Chaperone Expression in Human GEP-NET Cells Can Repress Their Proliferation and Sensitize Them to Chemotherapy
Introduction: New approaches for better treatment of gastroenteropancreatic neuroendocrine tumors (GEP-NETs) are acutely needed. Inhibitors of chaperone activity of heat shock protein 90 (Hsp90) seem to be promising agents but they upregulate cytoprotective chaperones Hsp70 and Hsp27.

#1396 3-Drugs Chemotherapy Regimen for G3 PanNENs with Ki67 below 55%: Single Institution Experience
Introduction: To date no standard regimen of chemotherapy (CTH) is universally approved for advanced pancreatic neuroendocrine neoplasms (PanNENs) with Ki67<55% and no predictive selection criteria is available.

#151 Rationale for combining mTOR with other targeted agents in the treatment of neuroendocrine tumors
Introduction: Advanced neuroendocrine tumors (NETs) are aggressive and incurable with standard treatment. Many cellular targets are being evaluated in this patient population, including mammalian target of rapamycin (mTOR), a kinase that is the central regulator of several signaling pathways related to cell growth, angiogenesis, and bioenergetics. Because mTOR serves as a neoplastic switch activated by many cancer-related mutations, mTOR inhibition may have broad efficacy across tumor types, including NETs. Somatostatin analogs (SSAs) have long been used to treat carcinoid symptoms in NET patients. The SSA octreotide long-acting release (LAR) demonstrated significant antitumor effects against advanced midgut NETs in the phase III PROMID study.

#2233 Potential Effects of Ketoconazole on ACTH-Producing and Non-ACTH-Producing Neuroendocrine Tumors
Introduction: Prolonged biochemical remission after treatment with steroidogenesis inhibitors has been described in patients with Cushing’s syndrome due to ectopic adrenocorticotropin hormone (ACTH) production. Some studies have suggested antiproliferative and apoptotic effect of ketoconazole in human cancer cells.

#42 Chemotherapy in the Treatment of Progressive, Undifferentiated Neuroendocrine Carcinomas: a Single-Center Experience.
Introduction: Treatment of poorly differentiated neuroendocrine tumors (NET) usually includes chemotherapeutic intervention. However, both the rarity and the heterogeneity of the disease have led to relatively few clinical trials. This study evaluated the outcome of two chemotherapy regimens in patients suffering from undifferentiated and histologically confirmed NET.

#154 Long-term disease stabilization in a patient with advanced pancreatic neuroendocrine tumor treated with combined everolimus and octreotide LAR after prior failure of cytotoxic therapy
Introduction: Targeting of multiple pathways has become an important strategy for improved tumor control in metastatic neuroendocrine tumors (NETs). Among these targets is the mammalian target of rapamycin (mTOR), a central regulator of cell growth, proliferation, and apoptosis, which is blocked by everolimus, an oral inhibitor of mTOR that has shown efficacy in patients with metastatic pancreatic NETs. Recent evidence has suggested that suppression of insulin-like growth factor-1 receptor (IGF-1R) secretion with octreotide therapy, along with concurrent inhibition of mTOR by everolimus, may improve tumor control synergistically by preventing feedback activation of the PI3K/Akt/mTOR pathway.
