Abstract
PURPOSE: To compare hematologic recovery in patients receiving allogeneic blood cell transplantation (BCT) with those receiving allogeneic bone marrow transplantation (BMT). PATIENTS AND METHODS: One hundred eleven patients with leukemia in the early stages and with HLA-matched sibling donors were randomized in this study. One hundred one underwent transplantation. Standard procedures for collection and transplantation were used. Patients did not receive prophylactic granulocyte colony-stimulating factor after undergoing transplantation. In addition to clinical end points being established, a prospective and comparative economic evaluation of the first 6 months after transplantation was performed. RESULTS: Groups were balanced for patient, donor, and transplant characteristics. Blood cell collection led to the collection of a higher number of CD34+ and CD3+ cells than did bone marrow collection (P < 10−6) without reported side effects for the donor. Patients in the BCT group reached platelet counts of 25 and 50 × 109 platelets/L 8 and 11 days earlier than did the BMT group (P < 10−4 and P < 10−5), respectively. This resulted in fewer platelet transfusions during the first 180 days after transplantation (P = .002) for the former group. The time to reach neutrophil counts of 0.5 and 1 × 109 neutrophils/L was 6 and 7 days shorter, respectively, in the BCT group than in the BMT group (P < 10−5). This quicker hematologic recovery was associated with a shorter length of hospitalization and a decrease in total cost of procedure during the first 6 months. CONCLUSION: This study establishes that allogeneic BCT results in quicker hematologic recovery but is associated with a higher occurrence of chronic graft-versus-host disease.
