Abstract
This study aimed to investigate the clinical outcomes of hematopoietic stem cell transplantation (HSCT) with total body irradiation-based myeloablative conditioning (TBI-MAC) in pediatric patients with acute lymphoblastic leukemia (ALL). We retrospectively examined patients with ALL who underwent HSCT with TBI-MAC from January 2000 to August 2016 at our institute. We enrolled 67 patients with a median follow-up period of 8 years. The 5-year event-free survival (EFS) and overall survival (OS) were 51.2% and 59.6%, respectively. At the first complete remission, HSCT exhibited significantly superior EFS and OS in our patients than that in patients with other diseases. We encountered 57.9% of patients with at least one late complication. Major late complications were short stature (26.3%) and hypogonadism (18.4%). While late complications were observed in several recipients of HSCT, late complication-related deaths occurred in three patients. The TBI-MAC regimen led to favorable clinical outcomes in pediatric patients with ALL who underwent HSCT. Thus, proper evaluation and management of late complications are mandatory.
