Blood test may foretell Radiation's toll on the gut

This observational study is investigating whether a blood marker called GLP-2 could help predict the risk and severity of acute radiation enteritis—a common and painful side effect of radiation therapy to the abdomen or pelvis. Researchers will measure GLP-2 levels in 50 adults before, at the end of, and one month after their standard radiotherapy, and track who develops gut inflammation. The goal is to see if changes in GLP-2 are linked to intestinal injury, inflammation, and quality of life, potentially paving the way for a simple blood test to guide care.
