#2888 Progression-Free Survival as a Surrogate Endpoint in Gastroenteropancreatic Neuroendocrine Tumors Treated with Somatostatin Analogues
Introduction: Progression-free survival (PFS) has been used as surrogate endpoint in phase III trials with somatostatin analogues for gastroentero-pancreatic neuroendocrine tumors (GEP-NET). However, this endpoint has not been validated in this scenario.

#2906 Change of Lactate Transporter (MCT4) Expression in Pancreatic Microadenomas and Stages of Pancreatic Neuroendocrine Tumors
Introduction: Metabolic changes are observed in early and late stages of Pancreatic Neuroendocrine Tumors (PanNET) in mouse models. In human PanNET, RNA-expression analysis showed changes in glucose metabolism in more aggressive PanNET.

#2962 90Y- and/or 177Lu-DOTATOC Re-Challenge in Patients with Progressive Neuroendocrine Tumors
Introduction: Most patients treated with PRRT will eventually progress. Previous studies indicated that repeated PRRT is feasible and promising.

#3013 Structurally-Optimized Peptide VMT-Alpha-NET Enhances the Efficacy of SSTR2-Targeted Alpha-Particle Therapy for Neuroendocrine Tumors
Introduction: 203Pb/212Pb is a promising theranostics pair for SSTR2-targeted alpha-particle therapy for neuroendocrine tumors (NETs). The development of SSTR2-targeted peptides that are optimized for the Pb isotopes has the potential to improve performance.

#29 Serum chromogranin A correlation with tumor burden in metastatic small bowel carcinoid patients
Introduction: Patients with neuroendocrine tumors may have clinical courses that range from fairly indolent to more aggressive. Cross–sectional studies, nuclear imaging and biochemical markers are often used to monitor disease progression. Optimal surveillance tests and intervals have not been firmly established. Studies suggest that chromogranin A (CgA) may be a surrogate marker for tumor burden.

#67 Interest of combined chromogranin A and pancreatic polypeptide for diagnosis and follow-up of gastroenteropancreatic endocrine carcinoma
Introduction: Assessment of tumor burden changes is essential for the management of well-differentiated gastroenteropancreatic neuroendocrine carcinoma (GEPNET). Chromogranin A (CgA) is the principal tumor marker for such tumors; however, its use to evaluate morphological tumor progression is not validated. Combined CgA and pancreatic polypeptide (PP) may increase sensitivity in the diagnosis of GEP-NET.

#128 Multidisciplinary reference centers: the need for combined expertise in the diagnosis and treatment of neuroendocrine tumors
Introduction: Neuroendocrine tumors (NETs) are a heterogeneous group of malignancies with increasing incidence (Yao et al. J Clin Oncol 2008;26:3063–72). Multidisciplinary reference centers (MRCs) can potentially offer better clinical outcomes by integrating and coordinating expert care from many specialties, reducing delays in treatments and referrals, and allowing for accrual to clinical trials. MRCs have achieved improved outcomes in ovarian, breast and lung cancers (Pollock. Ann Surg 2008;248:510–6; Gabel et al. Cancer 1997;79:2380–4; Forrest et al. Br J Cancer 2005;93:977–8). Despite this, MRCs focusing on NETs are uncommon.

#136 Prevalence, severity and clinical outcome of malnutrition in gastroenteropancreatic neuroendocrine tumors
Introduction: Malnutrition is well-known to unfavorably influence clinical prognosis in patients (pts) with malignant diseases. However, in patients with neuroendocrine tumors (NET) prevalence and outcome of malnutrition are unknown although the gastroenteropancreatic system is most frequently involved.

#158 Progression-free survival (PFS) as a primary endpoint for clinical studies in advanced neuroendocrine tumors (NETs)
Introduction: Successfully testing new antitumor agents requires primary study endpoints that are clinically important, and also provide sufficient statistical power within a timeframe and population size that is feasible for the tumor type. Using overall survival (OS) as the primary endpoint in NET studies is challenging because of the low incidence (5.25/100,000 annually), disease heterogeneity, extended survival time (Yao 2008), and confounding effects of multiple therapies. These inherent aspects of NETs make OS an extremely difficult and challenging endpoint to evaluate clinical efficacy.
