Abstract 839FN2 Many patients who require allogeneic hematopoietic stem cell transplantation (allo-HSCT) lack a human leukocyte antigen (HLA)-matched donor. Recently, we developed a new strategy named GIAC protocol for HLA-mismatched/haploidentical transplantation from family donors that combines granulocyte-colony stimulating factor (G-CSF) primed bone marrow (G-BM) and peripheral blood stem cells (PBSC) without in vitro T-cell depletion (TCD). For the past nine years, promising results for HLA-mismatched allo-HSCT without in vitro TCD have been achieved at our institute using this protocol. From May 2002 to December 2010, 820 patients, including 206 in high-risk group, underwent transplantation from haploidentical family donors. Eight-hundred and eleven patients (99%) achieved sustained, full donor chimerism. The incidence of grade 2–4 acute graft-versus-host disease (GVHD) was 42.9%, and that of grades 3 and 4 was 14.0% which was not associated with the extent of HLA disparity.Figure 1Cumulative incidence of acute GVHD grade 2–4 according to HLA disparity.Figure 1.

Abstract Clinical decisions in allogeneic hematopoietic stem cell transplantation (allo-HSCT) are supported by the use of prognostic scores for outcome prediction. Scores vary in their features and in the composition of development cohorts. We sought to externally validate and compare the performance of 8 commonly applied scoring systems on a cohort of allo-HSCT recipients. Among 528 patients studied, acute myeloid leukemia was the leading transplant indication (44%) and 46% of patients had a matched sibling donor. Most models successfully grouped patients into higher and lower risk strata, supporting their use for risk classification. However, discrimination varied (2-year overall survival area under the receiver operating characteristic curve [AUC]: revised Pretransplantation Assessment of Mortality [rPAM], 0.64; PAM, 0.63; revised Disease Risk Index [rDRI], 0.62; Endothelial Activation and Stress Index [EASIx], 0.60; combined European Society for Blood and Marrow Transplantation [EBMT]/Hematopoietic Cell Transplantation-specific Comorbidity Index [HCT-CI], 0.58; EBMT, 0.58; Comorbidity-Age, 0.58; HCT-CI, 0.55); AUC ranges from 0.5 (random) to 1.0 (perfect prediction). rPAM and PAM, which had the greatest predictive capacity across all outcomes, are comprehensive models including patient, disease, and transplantation information. Interestingly, EASIx, a biomarker-driven model, had comparable performance for nonrelapse mortality (NRM; 2-year AUC, 0.65) but no predictive value for relapse (2-year AUC, 0.53). Overall, allo-HSCT prognostic systems may be useful for risk stratification, but individual prediction remains a challenge, as reflected by the scores’ limited discriminative capacity.
