Optimized Peptide Amount and Activity for 90Y-Labeled DOTATATE Therapy
In peptide receptor radionuclide therapy with 90Y-labeled DOTATATE, the kidney absorbed dose limits the maximum amount of total activity that can be safely administered in many patients. A higher tumor-to-kidney absorbed dose ratio might be achieved by optimizing the amount of injected peptide and activity, as recent studies have shown different degrees of receptor saturation for normal tissue ...

UNLABELLED In peptide receptor radionuclide therapy with (90)Y-labeled DOTATATE, the kidney absorbed dose limits the maximum amount of total activity that can be safely administered in many patients. A higher tumor-to-kidney absorbed dose ratio might be achieved by optimizing the amount of injected peptide and activity, as recent studies have shown different degrees of receptor saturation for n...
متن کاملEfficacy and safety of 90Y-DOTATATE therapy in neuroendocrine tumours.
BACKGROUND The aim of this study was to assess the efficacy and toxicity of peptide receptor radionuclide therapy (PRRT) with the use of the high affinity somatostatin receptor subtype 2 analogue, (90)Y labelled Tyr3-octreotate, ((90)Y-DOTATATE) in neuroendocrine tumours (NETs). MATERIAL AND METHODS 46 patients with disseminated or non-operable NET were enrolled in this study. The (90)Y-DOTAT...
متن کاملNephrotoxicity after PRRT - still a serious clinical problem? Renal toxicity after peptide receptor radionuclide therapy with 90Y-DOTATATE and 90Y/177Lu-DOTATATE.
INTRODUCTION The kidneys play an essential role in PRRT. The infusion of amino acids could reduce uptake in the kidney of radiolabelled peptides. The purpose of this study was to determine the extent of kidney damage post PRRT. MATERIAL AND METHODS 53 patients, with disseminated neuroendocrine tumours (NET), received 3-5 cycles of up to a maximum 7.4 GBq/m2 calculated dose of 90Y-DOTATATE (n ...
متن کاملSynthesis and biodistribution study of a chlorotoxin derivative peptide labeled with 131- iodine for tumor therapy
Background: Chlorotoxin is a 36-amino acid peptide found in the venom of the Leiurus quinquestriatus which blocks small-conductance chloride channels. Chlorotoxin binds preferentially to glioma cells that allow development of new methods for the treatment and diagnosis of several types of cancer. Thus chlorotoxin derivative was labeled with 131I for further investigation. Materials and...
