#2997 Benefits of 177Lu-DOTATATE in Patients with Advanced Neuroendocrine Tumours: Case Reports from Two Patients with High Disease Burden

Introduction: In the NETTER-1 study, peptide receptor radionuclide therapy (PRRT) with 177Lu-DOTATATE increased progression-free survival (PFS) and time to deterioration in quality of life (QoL) in patients with advanced midgut neuroendocrine tumours (NETs), compared with octreotide.

#2967 Longitudinal Changes in Plasma 5-Hydroxyindoleacetic Acid (5-HIAA) and Other Biomarkers during Treatment of Functional Midgut Neuroendocrine Tumours (NETs) with Lanreotide Autogel: CALM NET Study Results

Introduction: CALM-NET (EudraCT 2013-002194-22; NCT02075606) evaluated pre-treatment circulating tumour cell levels in patients with NETs as a predictor of response to lanreotide autogel (LAN).

#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.
