Introduction: Somatostatin receptors expressed on a wide range of human tumors, are potential targets for the peptide receptor radionuclide therapy (PRRT). In this study, 177Lu-[DOTA-DPhe1, Tyr3]octreotide (177Lu-DOTATOC) as an agent for PRRT was prepared and its biodistribution was studied in rats. Methods:The ...

OBJECTIVE(S) In this study, (166)Ho-1,2-propylene di-amino tetra(methy1enephosphonicAcid) ((166)Ho-PDTMP) complex was prepared as a bone palliation agent. MATERIALS AND METHODS The complex was successfully prepared using an in-house synthesized EDTMP ligand and (166)HoCl3. Ho-166 chloride was obtained by thermal neutron irradiation (1 × 1013 n.cm-2.s-1) of natural Ho(NO3)3 samples followed by...

Uptake and dose distributions in peritoneal LS174T colon tumor xenografts were compared for a humanized construct of the CC49 (HuCC49) high-affinity anti-TAG-72 monoclonal antibody and a construct with the CH2 region deleted (HuCC49DeltaCH2), both labeled with (177)Lu using a PA-DOTA bifunctional chelating agent and injected in the peritoneum. Tumors were resected and serially sectioned at 1 h,...
