Summary
Brief summary (as posted)
This clinical trial evaluates the effects of hemoglobin threshold-specific packed red blood cell (PRBC) transfusions on quality of life and functional outcomes in patients who have undergone chemotherapy or an allogeneic hematopoietic stem cell transplant for a high-grade myeloid neoplasm, acute myeloid leukemia, or B acute lymphoblastic lymphoma/leukemia. Some types of chemotherapy and stem cell transplants can induce low platelet counts and/or anemia that requires PRBC transfusions. Given critical shortages in blood supply, and risks associated with transfusion of PRBC, there has been much investigation into the "minimum" hemoglobin level that effectively balances safety and toxicity in patients. This clinical trial evaluates the effects of giving PRBC transfusions based on a more restrictive hemoglobin threshold (\> 7 gm/dL) compared to a more liberal hemoglobin threshold (\> 9 gm/dL) on quality of life and functional outcomes. A more restrictive threshold may be just as effective at maintaining patient quality of life and function while decreasing side effects from blood transfusions and helping to conserve blood supply resources.
