In the early 1990s, 4 randomized studies compared conditioning regimens before transplantation for leukemia with either cyclophosphamide (CY) and total-body irradiation (TBI), or busulfan (Bu) and CY. This study analyzed the long-term outcomes for 316 patients with chronic myeloid leukemia (CML) and 172 patients with acute myeloid leukemia (AML) who participated in these 4 trials, now with a mean follow-up of more than 7 years. Among patients with CML, no statistically significant difference in survival or disease-free survival emerged from testing the 2 regimens. The projected 10-year survival estimates were 65% and 63% with Bu-CY versus CY-TBI, respectively. Among patients with AML, the projected 10-year survival estimates were 51% and 63% (95% CI, 52%-74%) with Bu-CY versus CY-TBI, respectively. At last follow-up, most surviving patients had unimpaired health and had returned to work, regardless of the conditioning regimen. Late complications were analyzed after adjustment for patient age and for acute and chronic graft-versus-host disease (GVHD). CML patients who received CY-TBI had an increased risk of cataract formation, and patients treated with Bu-CY had an increased risk of irreversible alopecia. Chronic GVHD was the primary risk factor for late pulmonary disease and avascular osteonecrosis. Thus, Bu-CY and CY-TBI provided similar probabilities of cure for patients with CML. In patients with AML, a nonsignificant 10% lower survival rate was observed after Bu-CY. Late complications occurred equally after both conditioning regimens (except for increased risk of cataract after CY-TBI and of alopecia with Bu-CY).

We analyzed long-term outcomes and psycho-social aspects in 112 children with malignancies surviving 1 year after hematopoietic stem cell transplantation. At 10 years, overall survival was 75+/-5%, TRM 18+/-4% and relapse 14+/-3%; 10-year cumulative incidence of infections was 31+/-4%, cataract 44+/-4%, pulmonary dysfunction 20+/-4%, bone and joint complications 29+/-5%, hypothyroidism 36+/-4%, cardiac complications 11+/-3% and secondary malignancies 7+/-3%. Total body irradiation (TBI) was the most significant risk factor associated with cataract, pulmonary impairment, osteoarticular complications and hypothyroidism. Chronic graft-versus-host disease was associated with higher incidence of pulmonary dysfunction. The number of complications per patient increased with time. Half of the patients had psychological disturbance, 13 signs of depression and 16 a history of eating behavior disorders; 54% of patients with one or more long-term complications had psychological problems. Sixty-nine patients had learning difficulties and 36 achieved normal scholarship. With increased follow-up, development of late effects and of psycho-social disturbance are of major concern. While the use of single-dose TBI has now been abandoned, other risk factors are still of concern in the early 2000s.
