All data are shown as No. (%) except for the Age category (mean and standard deviation [SD] and median [range]).
ALL, acute lymphoblastic leukemia; ATG, antithymocyte globulin; AYA, adolescent and young adult; CNI, calcineurin inhibitor; MMF, mycophenolate mofetil; MTX, methotrexate; PBSC, peripheral blood stem cell; PIF, primary induction failure; PT-CY, posttransplantation cyclophosphamide.
Other malignant diseases include plasma cell disorders (n = 6, adult group only), Ewing sarcoma (n = 3), rhabdomyosarcoma (n = 4), malignancies not otherwise specified (n = 7).
Disease risk index was calculated with the CIBMTR tool: https://www.cibmtr.org/ReferenceCenter/Statistical/Tools/Pages/DRI.aspx.
Included in this group were umbilical cord/double umbilical cord (n = 40 in patients age 10 years or younger; n = 20 in patients older than age 10 years).
