#4492 Utility of NETest 2.0 as a biomarker for neuroendocrine tumours: The Swiss experience – Real-world data

Introduction: The NETest 2.0 is a PCR assay of circulating mRNA, scored 0-100. It has been developed as a biomarker to diagnose neuroendocrine neoplasia (NEN) and to provide tumour prognostic information.

#4409 The value of NETest 2.0 in stratifying patients with suspected NEN for formal diagnostic evaluation – Real-world data

Introduction: An unmet need in NEN diagnosis is better risk stratification for individuals with suspected disease (based on symptoms or imaging), enabling efficient identification of those needing further evaluation and tissue diagnosis, thus speeding the process and reducing costs. NETest 2.0, a biomarker based on a 51-gene mRNA panel, was developed for diagnosing neuroendocrine neoplasia (NEN).

#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.
