#4661 Comparison of preoperative chemotherapy and radio ligand therapy on prognosis after surgical resection for locally advanced or hepatic metastatic pancreatic neuroendocrine tumours

Introduction: The role of preoperative treatments in improving the rate of radical resection and survival of either locally advanced (LA) or hepatic metastatic (HM) pancreatic neuroendocrine tumours (panNETs) is unclear.

#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.

#4615 Dosimetry, efficacy and safety of radiolabelled somatostatin receptor antagonist in patients with metastatic pheochromocytoma or paraganglioma

Introduction: Metastatic pheochromocytomas and paragangliomas (mPPGLs) are rare neuroendocrine tumours with a heterogenous phenotype and a variable treatment response. The SSTR antagonist [177Lu]Lu177Lu-DOTA-JR11 (177Lu-JR11) offers potentially increased tumour doses than standard radioligand therapy (RLT) with [177Lu]Lu-DOTA-TOC (177Lu-TOC).

#4589 Clinical efficacy of RLT to assess OS and PFS using 177Lu DOTATATE, 90Y DOTATATE, and a mixture of both in patients with advanced, unresectable, progressive rectal NET – A retrospective analysis

Introduction: Retrospective, single-arm, open-label, case series study evaluating the efficacy of different types of radioligand therapy (RLT): 177Lu, 90Y DOTATATE, or mix of both used in advanced, unresectable progressive rectal NETG1/G2.
