We prospectively studied the impact of risk stratification-directed interventions for minimal residual disease (MRD) on relapse and disease-free survival (DFS) in 814 persons with standard-risk acute leukemia receiving allotransplants in 1st or 2nd complete remission. 709 subjects were MRD-negative posttransplant (Group A). 105 subjects were MRD-positive; 49 received low-dose interleukin-2 (IL-2; Group B) and 56 received modified donor lymphocyte infusion (DLI) with or without low-dose IL-2 (Group C). Posttransplant immune suppression for graft-versus-host disease (GvHD) was also modified based on MRD-state. Cumulative risk of relapse was significantly less and DFS was significantly better in subjects in Group C than subjects in Group B (P=0.001 and P=0.002) and but not different than subjects in Group A (P=0.269 and P=0.688). Multivariate analyses confirmed MRD-state and modified DLI were significantly correlated with relapse (P=0.000, OR=0.255 and P=0.000, OR=0.269) and DFS (P=0.001, OR=0.511 and P=0.006, OR=0.436). These data suggest risk stratification-directed interventions with modified DLI in persons with standard-risk acute leukemia who are MRD-positive posttransplant may improve transplant outcomes. 8 w8 I- [; d% W/ S' ^8 H4 w4 t
