Radiation-infused nanoparticles wiped out brain tumors in rats

Human trials may launch within a few months for a new brain cancer treatment using nanoparticles infused with radiation that showed promise in rats. Researchers are continuing their efforts at the UT Health Science Center in San Antonio, and the journal Neuro-Oncology published results from the initial rat study. The television station KENS5 in San Antonio reported on the details. Researchers packaged the radiation in the nanoparticles, which travel a few millimeters to their source. The dosage used for rats was up to 30 times higher than typically-used radiation levels and helped eliminate the animals' tumors, according to the story. In human trials, the goal will be to deliver a targeted, high level of radiation to a glioblastoma or other brain tumor without hurting the surrounding healthy tissue. Story
