Outcome after allogeneic HSCT for pediatric HL according to conditioning regimen intensity (MAC vs RIC). Myeloablative (MAC) is indicated by solid line and reduced intensity (RIC) by dotted line. (A) Cumulative incidence for nonrelapse mortality. (B) Relapse rate is significantly increased after RIC (P = .01) from 9 months on. (C) Progression-free survival is lower (P = .02) from 9 months on after RIC. (D) Overall survival shows no significant differences between MAC and RIC regimens. HL indicates Hodgkin lymphoma; and HSCT, hematopoietic stem cell transplantation.
