Summary
This study tests whether transferring stool from a healthy person into the gut of adults with blood cancers can restore good bacteria lost during chemotherapy. The goal is to reduce dangerous infections and improve quality of life. One hundred participants will be followed long-term to see if the treatment helps control their disease and lowers the need for other medications.
