Gut bugs could make or break cancer treatment

This study looks at how the variety of bacteria in the gut (gut microbiome) might influence how well immunotherapy works in people with solid tumors. Researchers will collect stool and blood samples from 70 cancer patients starting immunotherapy to track changes in gut bacteria and immune markers. The goal is to understand why some patients respond better than others and how diet might play a role. This is an observational study, meaning it does not test a new treatment but gathers information to guide future research.
