    Abstract Blood or marrow transplantation (BMT) outcomes using haploidentical donors (Haplo) and posttransplant cyclophosphamide (PTCy)-based graft-versus-host disease (GVHD) prophylaxis compare favorably to HLA-matched donors using calcineurin inhibitor-based prophylaxis. A recent Center for International Blood and Marrow Transplant Research analysis of patients receiving homogenous PTCy-based prophylaxis found that, with reduced intensity conditioning, Haplo BMTs had worse outcomes than matched unrelated donor (MUD) BMTs. Due to significant differences between groups, we reanalyzed the dataset using propensity score matching and, additionally, added a donor age variable. After matching MUD BMTs to Haplo BMTs in a 1:5 ratio, no significant differences were found between groups across all measured baseline characteristics. Outcomes analyses demonstrated no significant differences in overall survival (hazard ratio [HR] of mortality with MUD vs Haplo [95% confidence interval], 0.95 [0.65-1.16], P = .75), disease-free survival (HR of relapse or death, 0.98 [0.73-1.18], P = .89), relapse rate (HR, 1.06 [0.77-1.38], P = .69), or nonrelapse mortality (NRM) (HR, 0.85 [0.42-1.13], P = .49) between groups. After stratification by conditioning intensity, MUD BMTs in the reduced-intensity cohort had lower risk of NRM (HR, 0.56 [0.14-0.99], P = .05), with no significant difference in other clinical outcomes. These results suggest the effect of HLA matching on BMT outcomes with PTCy is less meaningful than previously reported. Timely identification of a young, at least half-matched (related or unrelated) donor may be more important than finding a fully matched donor if the latter leads to a delay in BMT or use of an older donor.

    Abstract Follicular lymphoma (FL) exhibits striking biologic and clinical heterogeneity. Patients with newly diagnosed asymptomatic or low-bulk disease may be observed or managed with immunotherapies alone. Chemoimmunotherapy is considered a standard treatment for patients with advanced, symptomatic disease. In patients with FL who achieve at least a partial remission after first-line chemoimmunotherapy, autologous (auto-) hematopoietic cell transplantation (HCT) consolidation is not recommended; however, most patients with FL experience disease relapse after frontline therapies, with the experience of therapy failure within 2 years of first-line treatments predicting poor survival. Despite remarkable efficacy, even in patients who experience failure with other therapies, auto-HCT and allogeneic (allo-) HCT remain underutilized in relapsed/refractory FL, even among healthy and younger patients. Early use of auto-HCT consolidation should be considered a standard therapy option for high-risk patients who experience early failure of chemoimmunotherapy (< 2 years). For patients with FL who experience failure of frontline therapies late (> 2 years), deferring auto-HCT until later in the disease course is reasonable. Allo-HCT is best reserved for medically fit individuals with heavily pretreated disease, persistent marrow involvement, refractory, but low-bulk, disease, and in those who experience a failure to mobilize stem cells for auto-HCT. Allo-HCT is also a reasonable option for patients with FL who experience failure with a prior autograft; lower-intensity conditioning regimens and HLA-matched related donors are preferred in that setting. Future research should focus on the eradication of minimal residual disease before HCT and the prevention of disease relapse after HCT by integrating novel targeted agents into pre-HCT and post-HCT regimens.

    Abstract The Web-based One Year Survival Outcomes Calculator developed by the Center for International Blood and Marrow Transplant Research (CIBMTR) applies large-scale registry data to generate individualized estimates of overall survival (OS) probability 1 year after first allogeneic hematopoietic cell transplant (HCT) and can therefore provide a data-driven foundation for personalized patient counseling. We assessed the calibration of the CIBMTR One Year Survival Outcomes Calculator when applied to retrospective data among adult recipients of first allogeneic HCT for acute myeloid leukemia (AML), acute lymphoblastic leukemia (ALL), or myelodysplastic syndrome (MDS) with peripheral blood stem cell transplant (PBSCT) from a 7/8- or 8/8-matched donor from 2000 through 2015 at a single center. Predicted 1 year OS was estimated for each patient using the CIBMTR Calculator. Corresponding observed 1 year OS was estimated for each group by the Kaplan-Meier method. A weighted Kaplan-Meier estimator was used to visually display the average of observed 1 year survival estimates over the continuous range of predicted OS. In the first analysis of its kind, we demonstrated that the CIBMTR One Year Survival Outcomes Calculator could be applied to larger patient cohorts and predicted 1 year prognosis with general agreement between predicted and observed survival.

    Abstract Outcome differences by donor type for allogeneic hematopoietic stem cell transplantation vary based on disease and recipient age. The following paper summarizes analyses of transplant outcome among adults with acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) who received transplants from HLA-identical siblings, fully (8/8) matched unrelated donors (MUD), or mismatched (7/8) unrelated donors. The paper also reviews transplantation outcomes for children with leukemia who had genotypically matched sibling donors, mismatched (7/8) or phenotypically matched related donors or matched (8/8) unrelated donors. Morbidity is higher after unrelated donor vs HLA-matched sibling transplants due to higher rates of acute graft-vs-host disease (GVHD). However, survival is similar or within 10%-15% with all studies donor type, with disease-specific differences probably reflecting differences in underlying population risk for treatment-related mortality.

    Abstract Background: The Center for International Blood and Marrow Transplant Research (CIBMTR) provides a 1-year overall survival calculator to estimate outcomes for individual patients before they undergo allogeneic hematopoietic cell transplantation (HCT) to inform risk. The calculator considers pre-HCT clinical and demographic characteristics, but not patient-reported outcomes (PROs). Because pre-HCT PRO scores have been associated with post-HCT outcomes, the authors hypothesized that adding PRO scores to the calculator would enhance its predictive power.
    Methods: Clinical data were obtained from the CIBMTR and the Blood and Marrow Transplant Clinical Trials Network. The PRO measures used were the 36-Item Short Form Survey (SF-36) and the Functional Assessment of Cancer Therapy-Bone Marrow Transplantation. One thousand thirty-three adult patients were included.
    Results: When adjusted for clinical characteristics, the SF-36 physical component score was significantly predictive of 1-year survival (hazard ratio [HR], 0.88; 95% confidence interval [CI], 0.81-0.95; p = .0015), whereas the mental component score was not (HR, 1.02; 95% CI, 0.95-1.10; p = 0.6396). The baseline single general health question on the SF-36 was also significantly associated with mortality (HR, 1.91 for those reporting fair/poor health vs. good, very good, or excellent health; 95% CI, 1.33-2.76; p = .0005). The addition of PRO scores to the calculator did not result in a significant change in the model's predictive ability. Self-reported pre-HCT scores were strongly predictive of self-reported health status (odds ratio, 3.35; 95% CI, 1.66-6.75; p = .0007) and quality of life (odds ratio, 3.24; 95% CI, 1.93-5.41; p < .0001) after HCT.
    Conclusions: The authors confirmed the significant, independent association of pre-HCT PRO scores with overall survival, although adding PRO scores to the survival calculator did not improve its performance. They also demonstrated that a single general health question was as accurate as the full measure for predicting survival, an important finding that may reduce respondent burden and promote its inclusion in routine clinical practice. Validation of these findings should be performed.

    Abstract The treatment of acute myeloid leukemia is evolving, with increased understanding of molecular pathogenesis allowing better risk stratification and development of new therapies. Tests to identify and drugs to target specific molecular abnormalities are improving remission rates and prolonging survival in patients with high-risk disease. Allogeneic hematopoietic stem cell transplantation remains an important curative therapy, with advances in donor availability and approaches to reduce transplant-related mortality making it applicable in many more patients. Considerations in identifying appropriate patients for targeted therapy and transplantation are presented.

    Abstract Allogeneic hematopoietic stem cell transplantation (HCT) is the only curative therapy for myelodysplastic syndrome (MDS). Broad application is hindered by high risks of transplant-related morbidity and mortality, especially in the older age range represented by the MDS population. However, recent advances in strategies to minimize regimen-related toxicity make HCT a viable option for many more patients. Appropriate selection of patients involves consideration of patient factors, including use of geriatric assessment tools and comorbidity scales, that predict risks of regimen-related toxicity as well as disease factors, including genetic markers, which predict survival with both non-HCT and HCT therapy. Optimal timing of HCT for fit patients must consider MDS risk scores and life-years to be gained, with earlier transplantation indicated for patients with intermediate-2 and high-risk disease but judicious delay for lower risk patients. Selection of suitable conditioning regimens must balance risks of toxicity with opportunity for maximum disease control.

    Abstract For best results with unrelated donor transplantation of acute myeloid leukaemia (AML) patients, high-resolution typing should be completed for human leucocyte antigens (HLAs) A, B, C and DR. In the absence of an HLA-identical sibling, an unrelated adult donor, fully matched or with a single mismatch at these loci, should be used. If such a donor is not available in a timely manner, cord blood mismatched at one or two loci may be used. Data also suggest that peripheral blood transplantation may be more permissive of HLA mismatching than bone marrow transplants. Transplant decisions should be based on several factors, including availability of matched donors, as well as patient age, performance status and disease stage.
