Your gut bacteria might predict brain radiation injury risk

This study looks at whether the bacteria in your gut can help predict who might experience side effects from stereotactic radiosurgery (SRS), a precise type of radiation used to treat brain tumors. Researchers will collect stool and blood samples from 150 patients before and after their standard SRS treatment, and track their recovery over time. By comparing the gut microbiome and metabolic profiles of patients who develop radiation injury versus those who don't, the study aims to uncover biological clues that could improve risk prediction and guide future care.
