摘　　要：Alpha emitters are radionuclides with good pharmacological characteristics for the treatment of cancer because they decay by emitting high linear energy transfer particles.Recent advancements in isotope production and purification and the generation of novel techniques for optimum targeting have led to the development of targeted alpha therapy(TAT).The great cytotoxic potential ofα-particle emissions combined with monoclonal antibodies,peptides,small compounds,or nanoparticles has led to investigations of TAT in the preclinical context and more recently,in oncology clinical trials.Numerous studies have shown that TAT is effective both in vitro and in vivo.The firstα-emitter to obtain FDA approval for the treatment of prostate cancer with metastatic bone lesions was radium-223 dichloride.Many clinical trials are being conducted to evaluate the efficiency and safety of several radionuclides in cancer treatment,including radium-223,astatine-211,actinium-225,bismuth-213,lead-212,and thorium-227.This review provides an overview of the therapeutic use of these radionuclides and a summary of the studies that lay the groundwork for future clinical advancement.
