#4635 Comparison of 18F-DOPA PET/CT and 68Ga-DOTATOC PET/CT and their impact on response to PRRT in midgut neuroendocrine tumours

Introduction: 18F-DOPA PET/CT is a powerful diagnostic test for assessing tumour burden in midgut neuroendocrine tumours (NETs). 68Ga-DOTATOC PET/CT is required for patient selection for PRRT.

#4631 Correlations between dosimetry and imaging in patients with neuroendocrine tumour treated with 177Lu-DOTATATE

Introduction: Tumour dose may be an important predictor of clinical response, but estimation of a clinically relevant tumour-absorbed dose without high risk of toxicity is challenging.

#4630 Radiolabelled somatostatin receptor (SSTR) antagonist vs. agonist for peptide receptor radionuclide therapy (PPRT) in patients with SSTR positive neuroendocrine tumours – A retrospective basket study

Introduction: PRRT with lutetium-177 labelled somatostatin receptor (SSTR) agonists ([177Lu]Lu-DOTATATE or [177Lu]Lu-DOTATOC (177Lu-TOC) has limited response rate and durability. The SSTR antagonist [177Lu]Lu-DOTA-JR11 (177Lu-JR11) offers potentially increased tumour doses with better efficacy.

#4619 Targeted beta- plus auger and conversion electron therapy with terbium-161 labelled somatostatin receptor antagonist DOTA-LM3 – BETA plus phase 0 study

Introduction: Radioligand therapy with lutetium-177 labelled somatostatin receptor (SSTR) agonists (177Lu-DOTATATE or 177Lu-DOTATOC) showed limited response rate and durability. The novel SSTR antagonist DOTA-LM3 labelled with terbium-161, which co-emits conversion and Auger electrons in addition to β- particles, potentially increasing tumour doses and offering a more effective treatment for micro metastases.

#4612 Intraoperative beta-probe for pathological tissue detection in GEP-NET patients: A prospective phase II trial

Introduction: Accurate localisation of gastroenteropancreatic neuroendocrine tumours (GEP-NET) is essential for successful radical surgery. Radio guided surgery (RGS) is an innovative technique that may enhance lesion detection.
