#2996 A Head-to-Head Comparison between Two Software Packages for Hybrid Dosimetry after PRRT

Introduction: The number of dosimetry studies after PRRT is increasing, yet different methodologies are used which challenge comparison or pooling of results.

#2988 Epigenetic Treatment with Histone Deacetylase Inhibitor Enhances Uptake of [111In]In-DOTA-TATE by Increased SST2 Expression on Neuroendocrine Tumor Cells

Introduction: The somatostatin-2 receptor (SST2) is a target for peptide receptor radionuclide therapy (PRRT) in neuroendocrine tumors (NETs). By using epigenetic drugs, which can regulate gene transcription, PRRT efficacy may be further improved due to enhanced SST2 expression.

#2969 Lanreotide Autogel and Octreotide LAR Treatment Patterns: Results from a Nationwide French Retrospective Study

Introduction: Lanreotide autogel (LAN) and octreotide LAR (OCT) are long acting somatostatin analogues (LA-SSAs) used to treat acromegaly and gastroenteropancreatic neuroendocrine tumors (GEP-NETs). Previous studies conducted in North America and Sweden showed some differences between both LA-SSAs in terms of dose and persistence.

#2905 DNA Methyltransferase Inhibitor Hydralazine Induces Upregulation of Somatostatin Type 2 Receptors in Human Neuroendocrine Tumor Cells

Introduction: Epidrugs like DNA methyltransferase inhibitors (DNMTi) can increase somatostatin receptor type 2 (SST2) expression in neuroendocrine tumor (NET) cells in vitro and in vivo. This effect could be used for NET patients with low SST2 expression who are currently ineligible for somatostatin analogue (SSA) treatment. However, the DNMTi known to stimulate SST2 have either a high toxicity profile or are not yet approved.
