#1936 The Expression of IGF Signaling Pathway Genes Is Frequently Elevated in Pancreatic Neuroendocrine Tumors, but Is Downregulated in Metastases

Introduction: Studies have implicated EGFR, IGF and mTOR signaling pathways in the regulation of pNET growth. Interpretation of these studies is complex due to tumor subtype heterogeneity and differences in molecular analysis.

#654 Identification of Signaling Pathways Involved in Lung Carcinoid Progression Using Gene Expression Profiling

Introduction: Lung carcinoids are well-differentiated neuroendocrine tumors (NETs) usually associated with a favorable prognosis. Mechanisms underlying progression are poorly understood.

#462 Genome-Wide Expression Profiling Reveals Downregulation of OTP and CD44 and Upregulation of RET as Indicators of Poor Prognosis in Lung Carcinoids

Introduction: Lung carcinoids comprise a heterogeneous group of neuroendocrine tumors. Only few parameters have been identified that correlated with poor disease outcome, including 11q22-q25 deletions. New biomarkers are required to further improve diagnosis and prediction of prognosis.

#319 Expression of EGFR and IGF Pathway Genes in Insulinomas

Introduction: Anti-epidermal growth factor receptor (EGFR) therapy has been suggested in patients with inoperable/progressive endocrine pancreatic tumors (EPTs). However, various % EGFR-expressing EPTs are reported.

#212 Reduced MEN1 Gene Expression in Pulmonary Carcinoids Is Associated With Metastatic Disease

Introduction: Lung carcinoids are neuroendocrine tumors that can be classified as typical (TC) or atypical (AC) carcinoids. Previously, MEN-1 mutations and associated LOH of 11q13 have been implied in tumorigenesis.
