Abstract

While neutron activation of natural Tm2O3 is the convenient strategy for producing 170Tm for use in palliative care of painful bone metastases, the coproduction of 171Tm (t ½ = 1.92 years) is as an impediment towards its clinical utility. The production strategy has been optimized to obtain 170Tm with adequate specific activity and radionuclidic purity. Preliminary clinical studies carried out using the 170Tm-labeled ethylenediaminetetramethylene phosphonic acid (170Tm-EDTMP) showed site specific localization of the radiopharmaceutical in skeleton with preferential accumulation in metastatic lesions along with almost no accumulation in non-target organs, a distribution pattern comparable to that of 99mTc-labeled methylene diphosphonate (99mTc-MDP).
