#3320 TGF-β increase caspase activation and migration in typical bronchial carcinoids
Introduction: Typical bronchial carcinoids (TBC) are well-differentiated neuroendocrine neoplasms (NEN) whose management can still be very challenging due to reduced sensitivity to therapy. Previous studies have reported TGF-β’s ability to activate mTOR pathway and induce epithelial to mesenchymal transition (EMT). Moreover, preliminary results show an overexpression of TGF-β signalling and caspase activation in TBC.

#2944 Soluble ST2 (sST2) Levels in the Management of Carcinoid Heart Disease in Patients with Neuroendocrine Cancer
Introduction: The identification of a sensitive biomarker to detect the presence and severity of carcinoid heart disease could allow more selective use of clinical and echocardiographic screening. ST2 is a protein belonging to the family of interleukin 1 receptors, present both in the isoform of transmembrane (ST2L) and in the soluble one (sST2). sST2 blocks the anti-inflammatory, anti-hypertrophic, and anti-fibrotic effects of cytokine IL-33 on the myocardium and recent studies have shown that sST2 levels increase in the blood of patients diagnosed with heart failure.

#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.

#3020 Outcomes Following Surgical Management of Pulmonary Carcinoids – A Tertiary Center Experience
Introduction: Pulmonary carcinoids are a rare type of malignant lung tumour. Surgery forms the mainstay of management when operable. However, there is paucity of data on conservative management and effective follow-up strategies.

#2703 Carcinoid Heart Disease: A Retrospective Study and a Multidisciplinary Proposal of a New Algorithm
Introduction: Development of carcinoid heart disease (CHD) is the major negative prognostic factor in patients with the carcinoid syndrome. The only effective treatment is valve replacement. However, the selection of candidates and determination of optimal timing remain unclear. Considerable variability in local treatment strategies exist

#2840 A Real-World Study of Patients with Carcinoid Syndrome at King’s College Hospital on Long-Term Telotristat Therapy
Introduction: Telotristat ethyl is a tryptophan hydroxylase inhibitor that has been shown to be effective against symptoms of carcinoid syndrome refractory to standard somatostatin analogue therapy by directly inhibiting serotonin production. While clinical trials have established short-term efficacy of the drug, we report an exploratory real-world study of 15 patients with metastatic neuroendocrine tumours on long-term Telotristat (median duration=8 months).

#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.

#2745 Integrative Genomic Characterization Identifies Molecular Subtypes of Lung Carcinoids
Introduction: Lung carcinoids (LCs) are rare and slow growing primary lung neuroendocrine tumors. The WHO classify LCs into atypical and typical carcinoids. Recent studies have shown that the reproducibility of LCs classification and its prognostic efficacy have high interobserver variability

#2833 Surgical Correction of Carcinoid Heart Disease Improves Liver Function and 5-Hydroxyindoleacetic Acid Levels
Introduction: Neuroendocrine tumours of the gastrointestinal tract cause carcinoid syndrome and carcinoid heart disease. These tumours secrete serotonin, which can bind to heart valves and cause fibrosis and valve incompetence. Most cases involve the tricuspid valve +/- pulmonary valve. Medical management comprises diuretics for fluid overload and somatostatin analogues to reduce circulating serotonin. Definitive treatment is heart-valve replacement surgery which improves exercise tolerance but has high perioperative mortality. We have previously reported that valve-replacement surgery can reduce 5-hydroxyindoleacetic acid (5-HIAA) levels, reflecting a decline in hormone activity.
