No immune drugs needed: new microtransplant approach tested for leukemia patients

This early-phase study tested a new type of stem cell transplant (microtransplantation) in 25 people with acute myeloid leukemia or myelodysplastic syndromes who were too old or sick for a standard transplant. Unlike standard transplants, this approach used partially matched family donors and did not give patients immune-suppressing drugs afterward. The main goal was to see if this method could avoid severe graft-versus-host disease, a dangerous complication where donor cells attack the patient's body.
