A new targeted alpha therapy is showing promise for patients whose thyroid cancer no longer responds to radioactive iodine, the standard beta-emitting treatment. In a first-in-human study, investigators found that a single dose of the alpha-emitting radionuclide 211At (astatine) was both well-tolerated and effective, achieving disease control without molecularly targeted drugs. The findings were published in the December issue of The Journal of Nuclear Medicine. https://medicalxpress.com/news/2025-12-alpha-therapy-astatine-thyroid-cancer.html Sat, 06 Dec 2025 12:10:01 EST news684158535 Thyroid cancer is often a highly treatable disease.
