Summary

This study looks at how the bacteria in the gut (microbiome) are connected to cancer-related symptoms in children aged 5-18 with acute lymphoblastic leukemia. Researchers will collect stool samples and symptom reports at several points during chemotherapy. The goal is to understand these relationships, not to test a new treatment.
