Patients undergoing hematopoietic stem cell transplantation (HSCT) for hematologic malignancies during childhood have an increased risk of developing long-term sequelae that are in part attributable to the conditioning regimen. The present study aimed to assess the occurrence of long-term toxicities in a population of children who underwent HSCT for hematologic malignancies using either treosulfan or busulfan in the conditioning regimen. The cumulative incidences of growth impairment, altered gonadal function, altered thyroid function, cataracts, secondary malignant neoplasia, and altered pulmonary function were evaluated retrospectively by univariable and multivariable analyses in a population of 521 pediatric patients with acute leukemias or myelodysplastic syndromes treated in 20 Italian transplant centers affiliated with the Associazione Italiana Ematologia ed Oncologia Pediatrica (AIEOP). The median duration of follow-up for the entire study population was 7.1 years (range, 1 to 16 years). Overall, a larger proportion of patients given busulfan developed long-term toxicities compared to patients treated with treosulfan (34% versus 20%; P = .01). In univariable analysis, gonadal toxicity developed in 10% of patients who received treosulfan (95% confidence interval [CI], 3% to 15%), compared with 38% (95% CI, 24% to 39%) of busulfan-treated patients (P = .02), and this finding was confirmed by multivariable analysis (relative risk, .51; 95% CI, .34 to .76; P = .0009). We did not find any statistically significant associations between the occurrence of other long-term toxicities and the use of either busulfan or treosulfan. This study provides evidence that the use of treosulfan is correlated with a reduced incidence of gonadal toxicity in children undergoing HSCT for hematologic malignancies.
