Current therapies for acute myeloid leukemia (AML), failing induction, are rarely effective. We report our experience in 4 patients with AML who received 16 Gy TBI prior to allogeneic hematopoietic cell transplantation (alloHCT), between June 2010 and May 2011. Patients were 20 to 55 years of age, 2 with relapsed disease and 2 with AML failing induction. An HLA-matched graft from related or unrelated donor was infused on day 0. All but one, who received a CD34+-selected graft, received methotrexate and tacrolimus +/− antithymocyte globulin, as GVHD prophylaxis. The other patient received tacrolimus alone. Neutrophil and platelet engraftment occurred at a median of 18 and 14 days, respectively. Patients were discharged at a median of 28 days. There were no unexpected toxicities in the first 30 days. One patient had cytomegalovirus (CMV) viremia and anorexia, at two months. One patient had grade 2 acute GVHD of the skin. One patient developed chronic GVHD of the eyes, mouth, skin, joints, and lung at 4 months. Two patients died from relapse of their leukemia at days 65 and 125. Two patients remain in remission beyond day 1500. 16 Gy TBI followed by an alloHCT for AML, failing induction, is feasible and tolerable.

PurposeAllogeneic hematopoietic cell transplantation (HCT) after high-dose conditioning regimens imposes prohibitively high risks of morbidity and mortality for patients with high-risk acute myeloid leukemia (AML) who are older or have comorbid conditions. Here, we examined outcomes after nonmyeloablative allogeneic HCT in such patients.Patients and MethodsTwo hundred seventy-four patients (median age, 60 years) with de novo or secondary AML underwent allogeneic HCT from related (n = 118) or unrelated donors (n = 156) after conditioning with 2 Gy of total-body irradiation (TBI) with or without fludarabine. A calcineurin inhibitor and mycophenolate mofetil were used for postgrafting immunosuppression.ResultsWith a median follow-up of 38 months in surviving patients, the estimated overall survival at 5 years was 33%. The estimated 5-year relapse/progression and nonrelapse mortality rates were 42% and 26%, respectively. The cumulative incidences of grades 2, 3, and 4 acute graft-versus-host disease (GVHD) were 38%, 9%, and 5%, respectively. The cumulative incidence of chronic GVHD at 5 years was 44%. Patients in first and second complete remission had better survival rates than patients with more advanced disease (37% and 34% v 18%, respectively). Patients with HLA-matched related or unrelated donors had similar survivals. Unfavorable cytogenetic risk status was associated with increased relapse and subsequent mortality. Chronic GVHD was associated with lower relapse risk.ConclusionAllogeneic HCT from related or unrelated donors after conditioning with low-dose TBI and fludarabine, relying almost exclusively on graft-versus-leukemia effects, can result in long-term remissions in older or medically infirm patients with AML.

This study investigated the outcomes of allogeneic hematopoietic cell transplantation (allo-HCT) in acute myeloid leukemia (AML) patients with monosomal karyotypes (MK). A total of 114 AML patients who received allo-HCT were retrospectively analyzed. At the time of diagnosis, 13 patients were categorized with a favorable cytogenetic risk, 78 with an intermediate risk, and 23 with an adverse risk. MK was found in 12 patients among 23 with adverse cytogenetic risk. Pretransplant disease status was active disease in 5 cases (45.5%) in the adverse-risk without MK group, and 8 cases (66.7%) in the corresponding group with MK, 15 (19.2%) in the intermediate group and 4 (30.8%) in the favorable group. In multivariate analysis, active disease before transplant (hazard ratio, HR 3.913, p < 0.001), acute graft-versus-host disease (GVHD) ≥grade 2 (HR 1.908, p = 0.048) and chronic GVHD (HR 0.364, p = 0.001) affected overall survival (OS). The initial cytogenetic risk groups were not a significant risk factor for OS in allogeneic settings. The 2-year OS rate was 44.0 ± 15.9% without MK and 20.7 ± 17.9% with MK (p = 0.246). However, the OS rate was better for patients with chronic GVHD (p = 0.025). In conclusion, a survival benefit was observed for MK-positive patients with chronic GVHD in an allogeneic setting. However, the prognosis still remained poor for patients with MK. © 2014 S. Karger AG, Basel
