Targeted alpha therapy began to be applied to the treatment of late-stage cancer patients because of its dramatic therapeutic efficacy in patients who have no responses with beta-emitting radiopharmaceuticals. However, its strong cytotoxicity may cause side effects due to undesirable uptake in non-target tissues. In order to use alpha-emitting radiopharmaceuticals for early-stage patients as well as late-stage cancer patients, therefore, modifications on their chemical structures are required. In this review, the recent progress in the development of alpha-emitting radiopharmaceuticals is discussed.
