Radiolanthanides in therapeutic nuclear oncology

Abstract

Radiolanthanides such as Holmium-166 (T1/2 26.8h), Samarium-153 (T1/2 46.3h) and Lutetium-177 (T1/2 6.7 days) all have beta emissions suitable for radiopharmaceutical therapy, bone marrow ablation and for pain palliation of skeletal metastases. They also emit gamma photons of energies which permit quantitative imaging on conventional gamma cameras which facilitates calculation of dosimetry in individual patients. The range of half-lives has the potential to match the irradiation of tumour cells to the residence time of the radiopharmaceutical thus minimising radiotoxicity to normal tissues. Relative ease and low cost of production of these radiolanthanides in rectors such as HIFAR at ANSTO render radiolanthanides a practical option for radiopharmaceutical treatment of cancer for patients in whom conventional therapy has failed. Radioimmunotherapy of cancer using various monoclonal antibodies targeted to specific tumor-cell antigens has been performed with Samarium-153, Holmium-166 and Lutetium-177-labelled antibodies in human tumor xenographs in nude mice and in clinical trials. The development of a large animal model of human cancer will be described, in particular in relation to improving the accuracy of prediction of dosimetry and preclinical evaluation of efficacy and toxicity of radiolanthanides in therapeutic nuclear oncology
