This study is looking at how the tiny living organisms in your gut (your gut microbiome) might affect brain tumors. Researchers want to understand if there's a connection between your gut health and how brain tumors develop, grow, and respond to treatments like chemotherapy, radiation, or immunotherapy. You could join if you are 18 or older and are having surgery for a central nervous system tumor. The main goal is to collect samples and information to build a resource (biorepository) that will help future research. This collection is expected to take about one year, or until enough samples are gathered based on treatment schedules. The study is currently observational, meaning it involves collecting information and samples without giving any new treatments.
