Myeloablative allogeneic versus autologous stem cell transplantation in adult patients with acute lymphoblastic leukemia in first remission: a prospective sibling donor versus no-donor comparison

Abstract: While commonly accepted in poor-risk acute lymphoblastic leukemia (ALL), the role of allogeneic hematopoietic stem cell transplantation (allo-SCT) is still disputed in adult patients with standard-risk ALL. We evaluated outcome of patients with ALL in first complete remission (CR1), according to a sibling donor versus no-donor comparison. Eligible patients (433) were entered in 2 consecutive, prospective studies, of whom 288 (67%) were younger than 55 years, in CR1, and eligible to receive consolidation by either an autologous SCT or an allo-SCT. Allo-SCT was performed in 91 of 96 patients with a compatible sibling donor. Cumulative incidences of relapse at 5 years were, respectively, 24 and 55% for patients with a donor versus those without a donor (hazard ratio [HR], 0.37; 0.23-0.60; P < .001). Nonrelapse mortality estimated 16% (+/- 4) at 5 years after allo-SCT. As a result, disease-free survival (DFS) at 5 years was significantly better in the donor group: 60 versus 42% in the no-donor group (HR: 0.60; 0.41-0.89; P = .01). After risk-group analysis, improved outcome was more pronounced in standard-risk patients with a donor, who experienced an overall survival of 69% at 5 years (P = .05). In conclusion, standard-risk ALL patients with a sibling donor may show favorable survival following SCT, due to both a strong reduction of relapse and a modest nonrelapse mortality.
