    Abstract:
    Sixty-five children with acute lymphoblastic leukemia (ALL) underwent allogenic bone marrow transplantation (BMT) from an HLA identical donor, following cytoreduction with cyclophosphamide and total body irradiation (TBI): 15 were transplanted in 1st remission, 43 in 2nd and 7 in 3rd or in 4th. The Kaplan Meier estimate of surviving disease free at 4 years post BMT was 49.9% and the probability of continued remission at 4 years was 63.3%. Fourteen patients relapsed between 90 and 690 days (mean: 240 +/- 88) post BMT. The other causes of BMP failure included: graft versus host disease, veno-occlusive disease and sepsis. No interstitial pneumonitis has been reported. Patients who had a relapse while on chemotherapy had a higher probability of relapse than those who had a relapse while off therapy (p less than 0.01). We conclude that allogeneic BMT is the treatment of choice for children with ALL in second hematologic remission, the interval between diagnosis and first relapse being the most significant prognostic factor. Patients with poor prognosis might benefit from a more intensive chemotherapy/total body irradiation schedule or a BMT earlier in the course of their disease.
