Researchers at Mayo Clinic are building a research collection to study the connection between your gut bacteria and brain tumors. They believe that the microorganisms living in your digestive system may play a role in how brain cancer develops, progresses, and responds to treatment like chemotherapy, radiation, or immunotherapy. By studying samples from patients like you, scientists hope to discover new ways to improve outcomes.
Current brain tumor treatments don't work equally well for all patients, and doctors don't fully understand why. Recent research suggests that the bacteria in your gut may influence how your immune system fights cancer and how well you respond to therapy. This study aims to unlock those connections so future patients could receive better, more personalized treatment.

If you join, you'll provide several types of samples: blood, urine, saliva, and stool, as well as a small tissue sample related to your brain tumor surgery. You'll also complete questionnaires about your health and medical background. The study is observational, meaning researchers are collecting and analyzing information rather than testing a new drug or treatment—your regular care continues unchanged. Researchers will follow your information over time to see how your gut bacteria may relate to your disease and treatment response.
