    Abstract Allotransplantation cures patients by cytoreduction and the graft-versus-tumor (leukemia; graft-versus-leukemia [GVL]) alloresponse; both eliminate residual disease. The spectrum of conditioning intensity influences toxicities and non-relapse mortality. The spectrum of tumor sensitivity to the GVL response influences relapse. Balancing tolerable toxicities (influenced by patients' performance status and comorbidities) is also influenced by the graft. Intense immunosuppression (for engraftment and graft-versus-host disease prevention) may constrain the immunologic potency of the graft and limit the antineoplastic capacity of the transplant, thus requiring more intense or more effective conditioning regimens to limit the risks of relapse and permit satisfactory disease-free survival.

    Abstract Chimeric antigen receptor T-cell (CAR T-cell) therapy has revolutionized the treatment of hematologic malignancies in patients with relapsed or refractory disease without other treatment options. However, only a very small proportion of patients with an indication for CAR T-cell can access the treatment. The imbalance between supply and demand is magnified in minority and vulnerable populations. Limited access is multifactorial and in part a result of factors directly related to the cellular product such as cost, complex logistics and manufacturing limitations. On the other hand, the impact of diversity, equity, and inclusion (DEI) and their social and structural context are also key to understanding access barriers in cellular therapy and health care in general. CAR T-cell therapy provides us with a new opportunity to better understand and prioritize this gap, a key step towards proactively and strategically addressing access. The aim of this review is to provide an analysis of the current state of access to CAR T therapy with a focus on the influence of DEI. We will cover aspects related to the cellular product and the inseparable context of social and structural determinants. Identifying and addressing barriers is necessary to ensure equitable access to this and all future novel therapies.

    Abstract Despite advances in antimicrobial treatments, infection remains a common complication of intensive chemotherapy in patients with acute leukemia. It has become progressively apparent that the current antimicrobial focus has shortcomings that result from disruption of the commensal microbial communities of the gut. These effects, collectively known as dysbiosis, have been increasingly associated worldwide with growing complications such as Clostridioides difficile infection, systemic infections, and antibiotic resistance. A revision of the current practice is overdue. Several innovative concepts have been proposed and tested in animal models and humans, with the overarching goal of preventing damage to the microbiota and facilitating its recovery. In this review, we discuss these approaches, examine critical knowledge gaps, and explore how they may be filled in future research.

    Abstract Response to treatment of chronic graft-versus-host disease (cGVHD) may help predict prognosis and outcomes. We hypothesized that the response of cGVHD to treatment and the ability to taper immunosuppression define distinct treatment response categories that differ in terms of risk factors and prognosis. Our aim was to determine specific clinical characteristics and outcomes associated with 3 distinct cGVHD treatment response groups based on the response to and duration of immunosuppressive therapy (IST) as treatment-sensitive (TS), treatment-resistant (TR), and treatment-dependent (TD) cGVHD. This retrospective single-institution cohort study included 1142 consecutive adult and pediatric recipients of allogeneic hematopoietic cell transplantation (HCT) performed for malignant and nonmalignant disorders at the University of Minnesota between 2008 and 2016. All donor, graft, conditioning regimen, and GVHD prophylaxis strategies were included, but only patients who commenced systemic treatment within 30 days of cGVHD diagnosis were included. A total of 185 patients who developed cGVHD necessitating IST within 30 days of cGVHD diagnosis were included in this analysis. At 1 year after cGVHD onset, 13% of the patients were TS, 27% were TD, and 60% were TR (including 14% deceased), whereas at 2 years after cGVHD onset, 29% were TS, 5% were TD, and 66% were TR (including 22% deceased). In a landmark analysis starting at 1 year after cGVHD onset, 5-year failure-free survival (FFS) and overall survival (OS) were lowest in the TR group (FFS, 38%; OS, 70%), with comparable outcomes in the TD (74% and 82%, respectively) and TS (79% for both) groups. Compared to no cGVHD, TR cGVHD was associated with worse OS at 5 years after cGVHD (hazard ratio, 2.09 versus no cGVHD; 95% confidence interval, 1.3 to 3.3; P < .01). Our findings suggest that refining cGVHD classification into 3 treatment response states defines important predictors of early and late clinical outcomes and identifies patients needing more effective treatment.

    Abstract Patients with acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) generally require allogeneic hematopoietic cell transplantation (allo-HCT) for a cure, except for patients with favorable genetic genotypes such as those with core-binding factor AML. However, the use of intensive chemotherapy followed by prompt HCT does not fully prevent relapse or refractory disease. Despite improvements in transplant techniques and management of complications, further improvement of HCT outcomes is urgently needed. Moreover, careful patient counseling, donor selection, and choice of transplant type are essential to maximize the benefits of early allografting. Maintenance after HCT focusing on selective immunomodulation combined with targeted immunotherapies that control persisting or relapsed hematologic malignancies is currently under active investigation. To improve the balance between GVHD, relapse, and infection, the use of purified blood stem cell grafts in conjunction with

    Abstract With the recent development of transplant-specific composite endpoints for evaluation of allogeneic hematopoietic cell transplantation (alloHCT) outcomes, the use of these novel endpoints is growing rapidly. Combining multiple endpoints into a single endpoint, these composite endpoints appear simple and can be used as a summary measure for overall effectiveness of an intervention. However, all component endpoints may not have equal clinical significance, and an intervention may not work proportionally in the same direction for all components of a composite endpoint. This may complicate the interpretation of results, particularly if there are opposing effects of differing component endpoints. We assess the benefits and limitations of various composite endpoints used in alloHCT studies recently and propose guidelines for their use and interpretation. © 2021 American Society for Blood and Marrow Transplantation.

    Abstract Background: Autologous peripheral blood stem cell transplantation (aPBSCT) is the standard of care for adults with relapsed lymphoma, yet recipients remain at risk of developing chronic health conditions (CHCs). It was hypothesized that body composition measurements of skeletal muscle and fat are associated with late-onset CHCs and nonrelapse mortality after aPBSCT.
    Methods: Leveraging the Blood or Marrow Transplant Survivor Study, we examined association between pre-aPBSCT body composition and new-onset grade 3-5 CHCs among 187 adults with lymphoma treated with aPBSCT (2011-2014) surviving ≥2 years after aPBSCT. Using computed tomography scans at the L3 level, skeletal muscle mass (skeletal muscle area and skeletal muscle density [SMD]) and body fat (subcutaneous adipose tissue and visceral adipose tissue) were measured and quantified as sex-specific z-scores. Competing risk models were built to study the impact of body composition on incident grade 3 through 5 CHCs and nonrelapse mortality (NRM) adjusting for confounders.
    Results: The study cohort had a median age at aPBSCT of 57 years with 63% males, 77% non-Hispanic Whites and 81% with non-Hodgkin lymphoma. The 5-year cumulative incidence of grade 3 through 5 CHCs was 47% (95% Confidence Interval, CI, 38%-56%). Each SD increase in SMD was associated with 30% reduced risk of grade 3 through 5 CHCs (95% CI, 0.50-0.96). The 10-year cumulative incidence of NRM was 16% (95% CI, 10-22). No body composition measure was associated with NRM.
    Conclusions: The association between SMD and grade 3 through 5 CHCs following aPBSCT could inform development of prognostic models to identify adults with lymphoma at greatest risk of morbidity following aPBSCT.
