Abstract Fifty-seven children between the ages of 3 and 17 years with acute lymphoblastic leukemia (ALL) in chemotherapy-induced second bone marrow remission were given cyclophosphamide, total body irradiation, and bone marrow transplants from HLA-matched donors. Sixteen died of transplant- related complications. Eighteen relapsed between 56 and 833 days after transplantation, and 16 died of leukemia. Two survive in remission off treatment following chemotherapy. Twenty-three survive in continuous remission from 1.4 to 10.4 years after transplantation and the actuarial analysis shows disease-free survival of 40% with a plateau extending from 2.5 to 10.4 years.

Thirty-two children ranging in age from 1.5 to 16 years with poor-prognosis acute lymphoblastic leukemia (ALL) were treated with myeloablative immunosuppressive therapy consisting of cyclophosphamide (CPM) and total body irradiation (TBI) followed by allogeneic bone marrow transplantation (BMT) while in first complete remission (CR). The main reasons for assignment to BMT were WBC count greater than 100,000/microL, structural chromosomal abnormalities, and resistance to initial induction therapy. All children were transplanted with marrow from histocompatible siblings. Twenty-seven patients are alive in first CR for 7 to 82 months post-transplantation (median, 30 months). The actuarial disease-free survival rate is 84.4% (confidence interval, 7.2% to 29%) and the actuarial relapse rate is 3.5% (confidence interval, 0.9% to 13%). Four patients died of transplant-related complications, 16 developed low-grade acute graft-v-host disease (GVHD), and six developed chronic GVHD. The very low incidence of relapse (one of 28 long-term survivors) precluded the determination of the prognostic significance of the different poor-outcome features. Moreover, two infants treated with busulfan, CPM, and cytarabine (Ara-C) relapsed promptly in the marrow. In summary, as a means of providing long-term disease-free survival and possible cure, BMT should be considered for children with ALL presenting poor-prognostic features, particularly certain chromosomal translocations [t(4;11), t(9;22)], very high WBC counts, notably if associated with a non-T immunophenotype, and, perhaps, a poor response to initial therapy with corticosteroids (CS), or infants less than 6 months of age.

PURPOSE: Preparative regimens involving total-body irradiation (TBI) produce significant late toxicities in some children who receive bone marrow transplants, including impaired growth and intellectual development. Busulfan is often used as an alternative to TBI, but there are few data regarding its relative efficacy. PATIENTS AND METHODS: We compared outcomes of HLA-identical sibling transplants for acute lymphoblastic leukemia (ALL) in children (< 20 years of age) who received cyclophosphamide plus TBI (CY/TBI) (n = 451) versus those who received busulfan plus cyclophosphamide (Bu/CY) (n = 176) for pretransplant conditioning. Patients received transplants between 1988 and 1995 and their results were reported to the International Bone Marrow Transplant Registry by 144 participating institutions. The CY/TBI and Bu/CY groups did not differ in gender, immune phenotype, leukocyte count at the time of diagnosis, chromosome abnormalities, remission status, or length of initial remission. T-cell depletion was used more frequently in the CY/TBI group; the Bu/CY group included a higher proportion of children who were less than 5 years of age. The median follow-up period was 37 months. RESULTS: The 3-year probabilities of survival were 55% (95% confidence interval [CI], 50% to 60%) with TBI/CY and 40% (95% CI, 32% to 48%) with Bu/CY (univariate P = .003). The 3-year probabilities of leukemia-free survival were 50% (95% CI, 45% to 55%) and 35% (95% CI, 28% to 43%), respectively (univariate P = .005). In a multivariate analysis, the risks of relapse were similar in the two groups (relative risk [RR], 1.30 for Bu/CY v CY/TBI; P = .1). Treatment-related mortality was higher in the Bu/CY group (RR, 1.68; P = .012). Death and treatment failure (relapse or death, inverse of leukemia-free survival) were more frequent in the Bu/CY group (RR, 1.39; P = .017 for death; RR, 1.42; P = .006 for treatment failure). CONCLUSION: These data indicate superior survival with CY/TBI conditioning, compared with Bu/CY conditioning, for HLA-identical sibling bone marrow transplants in children with ALL.

Intent To Treat

Purpose To compare conventional sibling bone marrow transplantation (CBMT), BMT with alternative donor (ABMT), and chemotherapy (CT) for children with acute lymphoblastic leukemia (ALL) and an early first marrow relapse. Patients and Methods After informed consent, 214 patients with ALL and early marrow relapse began multiagent induction therapy. One hundred sixty-three patients with fewer than 25% marrow blasts and count recovery at the end of induction (second remission [CR2]) were allocated by donor availability. Fifty patients with sibling donors were allocated to CBMT. Seventy-two patients were randomly allocated between ABMT and CT while 41 patients refused allocation. Results Overall, 3-year event free survival from entry is 19% ± 3%. Thirty-two of 50 CBMT patients (64%) and 19 of 37 ABMT patients (51%) underwent transplantation in CR2 with 3-year disease-free survival of 42% ± 7% and 29% ± 7%. The 3-year DFS is 29% ± 7%, 21% ± 7%, and 27% ± 8% for patients allocated to CBMT, ABMT, and CT, respectively. Contrary to protocol, 12 of 35 patients allocated to CT underwent BMT in CR2. Of these, five patients died after BMT and 5 patients relapsed. Conclusion More than one half of patients died, failed reinduction, or relapsed again before 3 months after CR2 (median time to BMT). Intent-to-treat pair-wise comparison of ABMT with CT, CT with CBMT, and CBMT with ABMT yields hazards of 1.2, 1.1, 0.8 with P values of .56, .80, and .36, respectively. Outcomes remain similar and poor for children with ALL and early marrow relapse. BMT is not a complete answer to the challenge of ALL and early marrow relapse.

Relapse Group

Fifty-two patients with acute lymphoblastic leukemia (ALL) underwent allogeneic bone marrow transplantation following cytoreduction with total body irradiation and cyclophosphamide. Twenty-two patients were in second remission, 15 in a later remission, and 15 were in relapse at the time of the transplant. At a median follow-up of 24 mo, 14 of those in second remission survive in continuous remission compared to 5 in later remission and 4 in the relapse group. Statistical analysis showed an improved disease-free survival for the second remission group (p = 0.09). Patients transplanted in later remission or relapse had a similar survival. The improved survival in second remission resulted from a decreased relapse rate posttransplant, as the early mortality from nonleukemic causes was similar among the groups (p = 0.01). In the second remission patients, no characteristics of the initial leukemia were identified that significantly affected outcome. In the combined later remission and relapse group, poor prognosis posttransplant was associated with initial WBC greater than 20K, age at diagnosis older than 10, or initial remission duration less than or equal to 1 yr. These results suggest that extended disease-free survival may be achieved by second remission transplantation and that improved therapy is necessary for later remission or relapse transplants due to the high rate of posttransplant relapse.

Abstract Thirty-eight children between the ages of 0.8 and 17 years with acute nonlymphoblastic leukemia in first remission induced by chemotherapy were given cyclophosphamide, total body irradiation, and bone marrow transplants from HLA-matched donors. Six patients died of pneumonia, one died of metabolic problems, and one died of chronic graft-v-host disease complications. Five patients relapsed between six months and 3.2 years after transplantation. Three of the five died of leukemia, one survives with leukemia three years after transplantation, and one survives in remission off treatment following chemotherapy for 22 months. Twenty-five survive in continuous remission from 1.7 to 8.4 years after transplantation, and the actuarial analysis shows a disease- free survival rate of 64%, with a plateau extending from 3.5 to 8.4 years. All lead normal lives.
