Cesium-131 (Cs-131) brachytherapy seeds from medical isotope developer IsoRay Medical have been used at the University of Kentucky for gynecological cancer in a female patient whose disease recurred after previous radiation treatment.
The Cs-131 brachytherapy seed implant was the first time it has been used for the gynecological application, according to the company. Radiation oncologist Dr. Marcus Randall performed the procedure.
