#845 Ki-67 Index as a Biomarker of Response to Cytotoxic Chemotherapy
Introduction: Chemotherapy (CT) is widely used for neuroendocrine tumors (NET) but there are no validated biomarkers to predict response. The Ki-67 proliferation index has been proposed as a means of selecting patients for CT but robust data are lacking.

#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.

#1471 Chemotherapy for Stage IV Sporadic Pancreatic Neuroendocrine Tumors (pNET): Are Partial Responses to Post-first Line Chemotherapy Predictable by Response/Type of First Line Chemotherapy?
Introduction: Three types of chemotherapy are recommended for stage IV pancreatic neuroendocrine tumors (pNETs): streptozocin (STZ)-, dacarbazine (DCZ)- and oxaliplatin (OX)-based. Whether cross resistance exists is unknown.

#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.

#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.

#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.

#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.

#1205 Temozolomid-Based Therapy in GEP-and Bronchopulmonary NEN from a Multicentric Study from Germany
Introduction: Chemotherapy (CTx) with temozolomid as mono (TEM) or combination therapy with capcitabine (TEM/CAP) is a new cytotoxic regimen with good efficiency in pancreatic and bronchopulmonary NET-G1/G2 and NEC-G3.

#1404 The Proteasome Inhibitor Bortezomib Is a Highly Effective Treatment Option for Gastroenteropancreatic Neuroendocrine Neoplasms and Sensitizes to DNA Damaging Therapy In Vitro
Introduction: Gastroenteropancreatic neuroendocrine neoplasms are fairly rare tumors with very heterogeneous behavior and molecular characteristics. Their generally slow proliferation render them virtually resistant to many DNA damaging therapeutic approaches. Bortezomib has been shown to be effective in GEP-NENs in vitro but has been withdrawn from clinical assessment due to a small phase II study on bortezomib monotherapy in 2004.
