PURPOSE: Many attempts have been made to improve the results of allogeneic bone marrow transplantation (alloBMT) for patients with acute myeloid leukemia (AML) in first complete remission (CR1). Bone marrow cell dose has been reported to be an important factor in alloBMT; however, its true impact on relapse incidence (RI), leukemia-free survival (LFS), and nonrelapse mortality (NRM) in a large cohort of patients is unknown. PATIENTS AND METHODS: From January 1992 to December 1999, 572 bone marrow transplantation recipients reported to the European Blood and Marrow Transplantation (EBMT) registry underwent allografting from an HLA-identical sibling donor with an unmanipulated bone marrow for AML in CR1. RESULTS: The median number of nucleated cells (NCs) infused was 2.6 × 108/kg. Estimated 5-year NRM, LFS, and RI for patients receiving more or less than 2.6 × 108 NCs/kg were, respectively, 18% ± 5% v 30% ± 5% (P = .001), 68% ± 3% v 46% ± 3% (P < .00001), and 14% ± 4% v 24% ± 5% (P = .004). The association of cell dose with the above outcomes was confirmed in multivariate analyses for NRM (relative risk [RR], 0.53; P = .0007), for LFS (RR, 0.53; P = .00008), and for RI (RR, 0.57; P = .02). The cell dose was also an important factor for neutrophil (RR, 0.76; P = .009) and platelet (RR, 0.77; P = .03) recoveries; however, it did not statistically influence the incidence of acute graft-versus-host disease. CONCLUSION: This study shows that marrow cell dose is one of the most important factors influencing relapse, NRM, and LFS after alloBMT for patients with AML in CR1. Therefore, increasing the marrow cell dose should substantially improve the survival of these patients.

PURPOSE To report the impact of bone marrow transplantation (BMT) with busulfan/cyclophosphamide (BuCy) as end consolidation in a cohort of consecutively diagnosed children with acute myeloid leukemia (AML). PATIENTS AND METHODS Between May 1987 and November 1992, 43 patients were diagnosed with AML. Tissue typing at diagnosis determined whether patients would proceed to autologous or allogeneic BMT as end consolidation after six cycles of chemotherapy. Conditioning for BMT was with BuCy, followed by allogeneic or unpurged autologous marrow infusion. RESULTS Of 37 patients who received chemotherapy, 35 achieved remission (95%) after one to six courses of treatment and 34 (92%) were transplanted. Five relapsed before BMT, four were subsequently transplanted in second complete remission (CR2) (n = 3) or untreated first relapse (n = 1), and one failed to respond to further therapy. All other patients proceeded to BMT in first complete remission (CR1). Eleven patients received allografts: one relapsed and one died of graft-versus-host disease (GvHD), for a leukemia-free survival rate of 90% at a median of 41 months after BMT (range, 3 to 60). For 23 autografts, there were two toxic deaths and eight relapses, with a leukemia-free survival rate of 61% at a median of 11 months after BMT (range, 0 to 66). The high relapse rate following autologous BMT led us to escalate the dose of Bu from 16 mg/kg to 600 mg/m2 using a single daily dose of Bu. CONCLUSION With modern supportive therapy, most newly diagnosed children with AML will enter remission and are eligible for intensification therapy. BuCy is well tolerated in children, which allowed us to escalate the dose of Bu in recent patients. Further follow-up is needed to determine whether this has an impact on the relapse rate following autologous BMT.

Childhood acute myeloid leukemia (AML) has a poor prognosis with standard chemotherapy. Allogeneic bone marrow transplantation (BMT) in remission improves the outlook only for the one third of patients with sibling donors. Autologous BMT with a lower morbidity and mortality is available to all. In this study, maximum cytoreduction was achieved by intensive early chemotherapy. Final intensification, with autologous BMT was offered to all those remaining in first complete remission (CR). Patients received two induction and two consolidation courses of intensively scheduled chemotherapy. Cytoreduction was assessed on day 14 and remission was assessed after courses 2 and 4. Bone marrow was harvested after recovery from the second consolidation course or after the first maintenance course and separated on a discontinuous percoll gradient before cryopreservation. Twenty-eight of 31 consecutively enrolled patients achieved CR. Three relapsed early and, of the 25 eligible, 24 underwent autologous BMT. Twenty-three patients received high-dose melphalan and 1 received busulphan and cyclophosphamide before autologous BMT at a median of 113 days (range, 86 to 301) after initial CR. Trilineage engraftment occurred in all. Neutrophil recovery to greater than 0.5 x 10(9)/L occurred at a median of 46 days (range, 13 to 92) after autologous BMT. Platelet recovery was delayed, with a median time to achieve greater than 20 x 10(9)/L of 42 days (range, 18 to 215). With a minimum follow up of 25 months following autologous BMT only 3 children have relapsed. The 5-year event-free survival rate (EFS) from diagnosis is 68% (95% confidence interval, 46% to 90%). Five- year EFS following autologous BMT is 87% (95% confidence interval, 67% to 100%). Autologous BMT with high-dose melphalan administration after intensive chemotherapy has produced EFS equivalent to allogeneic BMT and is associated with a strikingly low relapse rate. High-dose melphalan appears to be a valuable agent for conditioning therapy in AML.
