WebNov 8, 2024 · Purpose Targeted α-therapy (TAT) for prostate-specific membrane antigen (PSMA) is a promising treatment for metastatic castration-resistant prostate cancer (CRPC). Astatine is an α-emitter (half-life=7.2 h) that can be produced by a 30-MeV cyclotron. This study evaluated the treatment effect of 211At-labeled PSMA compounds in mouse … Web1 day ago · A: Schematic of the CD46 targeted alpha therapy for prostate cancer cells. The development and preclinical evaluation of an alpha-particle therapy by targeting CD46 is a promising avenue for the treatment of prostate cancer.
WebThe effectiveness of targeted α-therapy (TAT) can be explained by the properties of α-particles. Alpha particles are helium nuclei and are ~8,000 times larger than β(-)-particles (electrons). When emitted from radionuclides that decay via an α-decay pathway, they … Targeted alpha-particle therapy (or TAT) is an in-development method of targeted radionuclide therapy of various cancers. It employs radioactive substances which undergo alpha decay to treat diseased tissue at close proximity. It has the potential to provide highly targeted treatment, especially to microscopic … See more The primary advantage of alpha particle (α) emitters over other types of radioactive sources is their very high linear energy transfer (LET) and relative biological effectiveness (RBE).
