#4593 Excellent response to Ac-225 DOTATATE therapy in a patient with small cell lung cancer

Introduction: Peptide receptor radionuclide therapy (PRRT) is a validated treatment for patients with NETs overexpressing somatostatin receptors (SSTR). IHC analysis indicates that up to 50% of small cell lung cancer (SCLC) tumours are SSTR2 positive and thus can be targeted by SSR imaging and PRRT. Therapy with α-emitting radionuclides, such as Ac225, may offer several advantages over β-emitters by having higher energy transfer and more effective cancer cell death.

#4553 The efficacy of “rechallenge” peptide receptor radionuclide therapy (PRRT) may be inferior to that of the initial PRRT, while the safety profile remains comparable

Introduction: Data on efficacy and adverse events of re-challenge PRRT (re-PRRT) for patients with gastrointestinal neuroendocrine tumours (GI-NETs) are limited.

#4421 Head-to-head comparison of 18F-AlF-NOTA-JR11 PET/MR and 68Ga-DOTATATE PET/CT in patients with neuroendocrine tumours: A prospective study

Introduction: PET/MR combines the molecular advantages of PET with excellent morphologic and anatomic delineation of MRI.18F-AlF-NOTA-JR11, a novel SSTR antagonist with a high affinity for SSTR2, has the potential to perform better than SSTR agonists in neuroendocrine tumour imaging.

#4324 The diagnostic and prognostic value of 68Ga-DOTANOC and 18F-FDG PET/CT for thymic carcinoids

Introduction: Thymic carcinoid (ThC) is an extremely rare type of neuroendocrine tumour. There is insufficient evidence to evaluate ThC using 68Ga-DOTANOC and 18F-FDG PET/CT.
