  • Beschreibung: [[sup 90]Y]DOTA-DPhe[sup 1]-Tyr[sup 3]-octreotide ([[sup 90]Y]SMT487) has been suggested as a promising radiotherapeutic agent for somatostatin receptor-expressing tumours. In order to quantify the in vivo parameters of this compound and the radiation doses delivered to healthy organs, the analogue [[sup 86]Y]DOTA-DPhe[sup 1]-Tyr[sup 3]-octreotide was synthesised and its uptake measured in baboons using positron emission tomography (PET). [[sup 86]Y]DOTADPhe[sup 1]-Tyr[sup 3]-octreotide was administered at two different peptide concentrations, namely 2 and 100 micro g peptide per m2 body surface. The latter concentration corresponded to a radiotherapeutic dose. In a third protocol [[sup 86]Y]DOTA-DPhe[sup 1]-Tyr[sup 3]-octreotide was injected in conjunction with a simultaneous infusion of an amino acid solution that was high in L-lysine in order to lower the renal uptake of radioyttrium.
