#3090 Retrospective Experience with Pherochromocytoma (PH) and Paraganglioma (PG) in a Single Argentinian Institution

Introduction: Pherochromocytoma (PH) and paraganglioma (PG) are neuroendocrine tumors arising in cromaffin cells in the adrenal medulla or extra adrenal paraganglia respectively. Clinical presentation is diverse. All PG/PH have malignant potential. Hereditary cases comprise up to 40% of all PG/PH.

#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.

#3025 Phase-II Trials of Pazopanib in Metastatic Neuroendocrine Neoplasia (NEN): A Systematic Review and Meta-Analysis

Introduction: Several Phase-II trials have been designed to evaluate Tyrosine Kinase Inhibitor (TKI) and in particular Pazopanib in Neuroendocrine Neoplasia (NEN) but it’s efficacy is not yet demonstrated in a randomized Phase III trial.

#3015 Biopsy Specimen Diagnosis in Pulmonary Carcinoids, A Shot in the Dark

Introduction: Pulmonary carcinoids (PCs) are rare well-differentiated neuroendocrine tumors, which can be separated into typical carcinoid (TC) and atypical carcinoid (AC). Advised treatment for local carcinoid disease is surgical resection using lobectomy, while parenchymal saving strategies such as sub-lobar or endobronchial resection might be considered for TC. In general, pre-operative diagnosis using a (transbronchial/transthoracic) biopsy sample is performed to demonstrate malignancy. However, TC and AC classification can solely be performed on surgical resection specimens, which may challenge pre-operative treatment decisions.
