Introduction: The management of patients with neuroendocrine neoplasms (NEN) has been revolutionised since the introduction of radiolabelled somatostatin analogues targeting overexpressed somatostatin receptors (SSTR). Accurate assessment of SSTR status of primary focus/metastases is crucial to determine the choice of the treatment method. Recently it has been shown that novel molecular probes, SST2-antagonists, recognize more binding sites in comparison to the wide...

Introduction: The good expression of somatostatin receptors in neuroendocrine tumor tissue enables effective treatment with peptide receptor radionuclide therapy (PRRT). To date, there is no clear consensus on the optimal PRRT arrangement due to the possibility of the use of different radiopharmaceutical regimens. In theory, the simultaneous use of two radionuclides (90Y and 177Lu) with different energy and radiation ranges should be more effective than monotherapy. The main o...

Introduction/Aim: Within the past two decades, the imaging and treatment of patients with neuroendocrine neoplasms (NEN) has been redefined by the successful introduction of radiolabelled somatostatin receptor (SSTR)-agonists targeting SSTR-subtype2 (SSTR2) overexpressed in NEN cells. Reliable assessment of the SSTR status of the primary focus/metastasis in different NEN locations is a cornerstone of NEN management and enables a personalised/precise therapeutic appr...

Aim/Introduction: Peptide Receptor Radionuclide Therapy (PRRT) is an effective treatment for disseminated neuroendocrine tumors (NETs) expressing somatostatin receptors. Despite many published studies, the consensus on the optimal PRRT treatment algorithm has not been reached yet. The main objective of the DUONEN multicenter, randomized, phase III study (EUDRACT No: 2020-006068-99) is the development of a dosimetry-based personalized PRRT algorithm. The second goal includes th...
