#1555 Antitumor Activity of Desmopressin (dDAVP) and the New Analog [V4Q5]dDAVP in Human Small Cell Lung Cancer
Introduction: Lung cancer is the main cause of cancer death. Non small cell lung cancer (NSCLC) cause about 85% of cases and small cell lung cancer (SCLC) represents 15%. Therapy resistance is commonly related with a transformation from adenocarcinoma to SCLC. SCLC shows neuroendocrine (NE) features and exhibits aggressive behavior. In vitro production of vasopressin (AVP) was reported in SCLC. The AVP V1 receptors are associated with mitogenic signaling pathways, while AVP V2 receptor (V2r) is related with an opposite effect. DDAVP is a synthetic analog of AVP that acts as a selective agonist for V2r. DDAVP displays cytostatic and antimetastatic properties in breast and colorectal cancer. In our laboratory a new analog, [V4Q5]dDAVP, showed improved cytostatic activity

#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.

#19 Antitumor activity of Pasireotide (SOM230) alone and in combination with Everolimus (RAD001) in DU-145 human prostate cancer model
Introduction: Pasireotide (SOM230) is a novel multi-receptor ligand somatostatin analogue with high affinity for somatostatin receptor subtypes sst1,2,3 and sst5. Like octreotide, which binds primarily to sst2, it inhibits hypersecretion of hormones from patients with functional pituitary tumors and gastroenteropancreatic neuroendocrine (GEP/NET) tumors. In addition, tumor shrinkage has been observed with both compounds in patients with acromegaly, Cushing’s disease and GEP/NETs, but its tumor-reducing mechanism of action has so far not been revealed. In patients with breast and liver cancer, octreotide had little or no antitumor activity.

#726 Expression and Phosphorilation of mTOR Pathway and Antitumor Activity of mTOR Inhibitors in Neuroendocrine Tumors
Introduction: The mammalian target of rapamycin (mTOR) is a protein kinase involved in the control of cancer cell metabolism, growth and proliferation. The mTOR pathway has attracted broad scientific and clinical interest, particularly in light of the ongoing clinical cancer trials with mTOR inhibitors in pts with neuroendocrine tumors (NETs). To identify the best candidates for treatment with mTOR inhibitors is challenging.

#1475 Tumor Growth Rate (TGR) as an Indicator of Antitumor Activity with Lanreotide Autogel/Depot (LAN) vs Placebo (Pbo) in Intestinal/Pancreatic NET: Post Hoc Analysis of CLARINET Data
Introduction: TGR is a novel measure of tumor growth activity that may be more precise than RECIST for evaluating response to treatment of NETs.

#602 Antitumoral Effect of Everolimus in Preclinical Models of Poorly Differentiated Neuroendocrine Carcinomas
Introduction: For the small and large cells poorly differentiated neuroendocrine carcinomas (PDNECs) emergency treatment remains the combination cisplatin/etoposide. However, recent studies suggest that targeted therapies could be a therapeutic option for this group of highly aggressive carcinomas.

#2265 Activity of Bevacizumab in Neuroendocrine Neoplasms
Introduction: The combination of the anti-VEGF antibody bevacizumab (BEV) with a multitude of other antineoplastic substances has shown promising activity in neuroendocrine neoplasms (NEN). However, data proving the superiority of BEV-containing vs. BEV-free protocols are lacking.

#1875 Potential Anti-Tumor Activity of Biguanides and Statins in Neuroendocrine Tumor Cells
Introduction: Recent studies have suggested that biguanides and statins have beneficial effects on various cancer types; however, the precise effects and the molecular mechanisms underlying this pathophysiological association are still not well understood in neuroendocrine tumor (NETs).
