#4363 61Cu-NODAGA-LM3 for the detection of neuroendocrine tumours: Preliminary results of the COPPER PET in NET trial, a randomised, crossover, readers blind, phase I/II non-inferiority study

Introduction: Currently approved PET tracers, Gallium-68 or Copper-64 labelled somatostatin receptor (SST) agonists (NETSPOT®, SOMAKIT® and Detecnet™), for imaging well-differentiated gastroenteropancreatic and bronchopulmonary neuroendocrine tumours (NET) have limitations. Radiolabelled SST antagonists offer superior imaging properties over agonists, and the combination with Copper-61, an unexplored PET isotope with a 3.33-hour half-life and favourable production characteristics, could be promising.

#4050 PET/CT imaging of the somatostatin receptor with [18F]AlF-NOTA-octreotide PET/CT: Analysis of impact on tumor staging and therapeutic management

Introduction: [18F]AlF-NOTA-octreotide ([18F]AlF-OC) is a promising alternative for [68Ga]Ga-DOTA-somatostatin analogues (SSAs) in PET imaging of the somatostatin receptor (SST).

#3852 Novel insights to study the potential of the somatostatin system in NETs and NECs

Introduction: Neuroendocrine tumors (NETs) and carcinomas (NECs) are a heterogeneous group of cancers with increasing incidence worldwide. Surgery is the only curative choice, whereas an effective pharmacological approach for disseminated disease is still lacking. Somatostatin (SS) receptors (SSTs) provide a suitable pharmacological target to treat NETs with SS analogues (SSAs). However, a large proportion of NETs and, particularly most NECs, are unresponsive or resistant to SSAs. The underlying causes remain poorly understood and alternative strategies are needed. Recently, cortistatin (CST), a neuropeptide analogue of SS with comparable affinity to SSTs, emerged as an anti-inflammatory player, with potential antitumoral features.

#1324 Somatostatin receptor PET/CT with radiolabelled antagonist is twice as effective as the agonist for detecting liver metastases: Results of a phase I/II study comparing 68Ga-OPS202 with 68Ga-DOTATOC PET/CT in gastro-entero-pancreatic neuroendocrine tumor p

Introduction: 68Ga-DOTATOC PET/CT is a reference method for imaging somatostatin receptor (sst) expressing tumors (NET). Presence of liver metastases impacts on patient management and prognosis.

#747 A Single-Center, Open-Label, Phase II, Proof-of-Concept Study with Pasireotide LAR in Patients with Progressive Medullary Thyroid Cancer (MTC): Preliminary Data

Introduction: MTC is a well-differentiated neuroendocrine tumor in which somatostatin receptor (sst) expression is higher for sst1 and sst5 than for sst2. This may explain why the available sst2–selective analogues do not work in these patients and why pasireotide (SOM230), a novel, multi-receptor targeted somatostatin analogue with high-binding affinity for sst1, 2, 3 and sst5 could be effective.
