#3030 Targeting CXCR4 and Thioredoxin Reductase in Theranostics of Atypical Carcinoid and Neuroendocrine Carcinoma

Introduction: Atypical carcinoid and small cell lung cancer (SCLC) are currently incurable. There is thus a critical need for new diagnostic and therapeutic strategies for lung neuroendocrine neoplasms (LNEN). Chemokine receptor 4 (CXCR4), a G protein coupled receptor and theranostic target, plays a crucial role in metastases of LNEN. We hypothesize combination of thioredoxin reductase (TR) inhibitor represents a metabolic strategy to enhance cytotoxicity in peptide-receptor radionuclide therapy (PRRT) of LNEN.

#2685 Apatinib Inhibits Tumor Growth and Angiogenesis in PNET Models

Introduction: Angiogenesis has a pivotal role in the growth and metastasis of pancreatic neuroendocrine tumors (PNETs). Apatinib inhibits angiogenesis as a highly selective KDR inhibitor and has been used to treat advanced gastric cancer and malignancies in clinical settings. However, the efficacy of apatinib in PNETs remains unclear.

#2233 Potential Effects of Ketoconazole on ACTH-Producing and Non-ACTH-Producing Neuroendocrine Tumors

Introduction: Prolonged biochemical remission after treatment with steroidogenesis inhibitors has been described in patients with Cushing’s syndrome due to ectopic adrenocorticotropin hormone (ACTH) production. Some studies have suggested antiproliferative and apoptotic effect of ketoconazole in human cancer cells.

#1847 CXCR4 Inhibition by Ulocuplumab Prevents EMT of pNET Cells in Vitro

Introduction: Neuroendocrine tumors (NETs) overexpress CXCR4. We have previously shown that stimulation of CXCR4 by its ligand SDF-1 promotes the epithelial-mesenchymal transition (EMT) and increases distant tumor spread. Ulocuplumab (Ulo) is a fully human IgG4 mAb designed to inhibit the binding of CXCR4 to SDF-1.
