#2091 Differential Signalling Pathways Drive Therapeutic Resistance in Neuroendocrine Tumors

Introduction: Most of the current therapeutic strategies used for neuroendocrine tumors (NETs) are insufficient due to poor knowledge of these tumours. Despite showing differentiated features, NETs often exhibit therapeutic resistance to common treatments similarly to other cancers. Although signalling abnormalities have been reported, molecular mechanisms responsible for this resistance phenomenon are yet to be understood.

#1739 A Kinomic Approach to Identify Signaling Proteins Involved in Drug Resistance in GastroEnteroPancreatic Neuroendocrine Tumors

Introduction: Most of the current therapeutic strategies used for neuroendocrine tumors (NETs) result in tumour growth stabilization, eventually followed by tumour progression. Thus, despite their original characteristics, NETs exhibit similar resistance features to treatments than other more common tumours.

#1476 Efficacy of Everolimus and Somatostatin Analogs as Single Agents or in Combination in Human Pancreatic Neuroendocrine Tumors Primary Cultures

Introduction: Among the therapeutic options available for the treatment of neuroendocrine tumors, one targeted therapy, everolimus (RAD) has been approved for advanced progressive pancreatic neuroendocrine tumors (pNETs). It improve progression free survival but is not curative. Alterations of the PI3K/Akt/mTOR pathway in pNETs have given the rational for the use of this signaling pathway inhibitors.

#1351 Sunitinib (SU) in Patients with Advanced, Progressive Pancreatic Neuroendocrine Tumors (pNET): Final Overall Survival (OS) Results from a Phase III Randomized Study Including Adjustment for Crossover

Introduction: This pivotal, Phase 3, double-blind study of SU in patients (pts) with advanced, progressive pNETs met its primary endpoint with median progression-free survival of 11.4 months (mo) for SU vs 5.5 mo for placebo (PBO; HR=0.42; 95% CI 0.26–0.66; p<0.001). OS difference favored SU (HR=0.41; 95% CI 0.19–0.89; p=0.02). At 2 years after study closure, median OS was 33.0 mo for SU vs 26.7 mo for PBO (HR=0.71; 95% CI 0.47–1.09; p=0.115).

#332 Impact of Baseline Ki-67 index and Other Baseline Characteristics on Outcome in a Study of Sunitinib (SU) for the Treatment of Advanced, Progressive Pancreatic Neuroendocrine Tumor (NET)

Introduction: Baseline Ki-67 index and other characteristics may influence outcome in patients (pts) with pancreatic NET; however, the value of Ki-67 and others have not been evaluated prospectively in trials.
