Figure 2. Adjusted cumulative incidence of treatment-related mortality and relapse in adult ALL patients by transplant conditioning regimen.
Conditioning was not significantly associated with TRM in multivariate analysis. However, patients in the BU group had increased 1.46 (95% C.I.: 1.15-1.85) relative risk for relapse, p=.002, compared with patients in the TBI group.
Abbreviations: TBI, total body irradiation; Bu, busulfan; N, number; HCT, hematopoietic cell transplantation; ALL, acute lymphoblastic leukemia
