Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare hematologic malignancy with historically poor outcomes and no worldwide consensus treatment approach. Unique among most hematologic malignancies for its frequent cutaneous involvement, BPDCN can also invade other extramedullary compartments, including the central nervous system. Generally affecting older adults, many patients are unfit to receive intensive chemotherapy, and although hematopoietic stem cell transplantation is preferred for younger, fit individuals, not all are eligible. One recent therapeutic breakthrough is that all BPDCNs express CD123 (IL3Rα) and that this accessible surface marker can be pharmacologically targeted. The first-in-class agent for BPDCN, tagraxofusp, which targets CD123, was approved in December 2018 in the United States for patients with BPDCN aged ≥2 years. Despite favorable response rates in the frontline setting, many patients still relapse in the setting of monotherapy, and outcomes in patients with relapsed/refractory BPDCN remain dismal. Therefore, novel approaches targeting both CD123 and other targets are actively being investigated. To begin to formally address the state of the field, we formed a new collaborative initiative, the North American BPDCN Consortium (NABC). This group of experts, which includes a multidisciplinary panel of hematologists/oncologists, hematopoietic stem cell transplant physicians, pathologists, dermatologists, and pediatric oncologists, was tasked with defining the current standard of care in the field and identifying the most important research questions and future directions in BPDCN. The position findings of the NABC’s inaugural meetings are presented herein.

Prior studies report a greater incidence of second primary malignancy (SPM) among patients with myeloproliferative neoplasms, although the true risk in primary myelofibrosis (PMF) has not been elucidated. We utilized the Surveillance, Epidemiology, and End Results database to evaluate the risk of SPM in PMF patients and analyzed the effects of sociodemographic factors on the risk of SPM. Out of 5273 patients, 385 patients (7.30%) developed SPM. SPM occurred at SIR of 1.95 (95% CI 1.76-2.15) and AER of 149.01 per 10,000 population. A significantly higher incidence of melanoma (SIR 1.76, 95% CI 1.01-2.86), lymphoma (SIR 3.38, 95% CI 2.28-4.83), and leukemia (SIR 27.19, 95% CI 23.09-31.81) was observed. The risk was significantly higher in patients ≤60 years, males, chemotherapy recipients, within 5 years of PMF diagnosis, and for PMF diagnosed after 2009.

PURPOSE Clinical trials are important for managing older patients with AML. We investigated differences in outcomes of older patients with AML on the basis of whether patients participated in intensive chemotherapy trials at community versus academic cancer centers. METHODS We used data from the Alliance for Clinical Trials in Oncology phase III trials that enrolled patients age ≥ 60 years with newly diagnosed AML between 1998 and 2002 in the Cancer and Leukemia Group B (CALGB) 9720 trial and between 2004 and 2006 in the CALGB 10201 trial. Centers funded by the NCI Community Oncology Research Program were identified as community cancer centers; others were designated as academic cancer centers. Logistic regression models and Cox proportional hazards models were used to compare 1-month mortality and overall survival (OS) by center type. RESULTS Seventeen percent of the 1,170 patients were enrolled in clinical trials in community cancer centers. The study results demonstrated comparable rates of grade ≥3 adverse events (97% v 93%), 1-month mortality (19.1% v 16.1%), and OS (43.9% v 35.7% at 1 year) between community versus academic cancer centers, respectively. After adjusting for covariates, 1-month mortality (odds ratio, 1.40; 95% CI, 0.92 to 2.12; P = .11) and OS (hazard ratio, 1.04; 95% CI, 0.88 to 1.22; P = .67) were not statistically different among patients treated in community versus academic cancer centers. CONCLUSION An older patient population, who have complex health care needs, can be successfully treated on intensive chemotherapy trials in select community cancer centers with outcomes comparable with that achieved at academic cancer centers.

The field of malignant hematology is transforming with novel immunotherapeutic approaches. Unfortunately, quality of life, treatment efficacy, and life expectancy are negatively affected by cardiotoxic side effects of treatment. To date, the exact mechanism and incidence of cardiotoxicity associated with these therapies is unclear. These events are believed to be triggered or occur concurrently with cytokine release syndrome. Furthermore, there are no formal guidelines to provide evaluation, treatment, and surveillance. We aim to synthesize available literature with updates on the cardiotoxic effects of novel therapies used in malignant hematologic disorders, with a focus on chimeric antigen receptor T-cell therapy and bispecific T-cell engager therapy, along with a proposed algorithm that may guide pretreatment evaluation, monitoring during treatment, and post-treatment surveillance.

Little is known about whether risk classification at diagnosis predicts post-hematopoietic cell transplantation (HCT) outcomes in patients with acute myeloid leukemia (AML). We evaluated 8709 patients with AML from the CIBMTR database, and after selection and manual curation of the cytogenetics data, 3779 patients in first complete remission were included in the final analysis: 2384 with intermediate-risk, 969 with adverse-risk, and 426 with KMT2A-rearranged disease. An adjusted multivariable analysis detected an increased risk of relapse for patients with KMT2A-rearranged or adverse-risk AML as compared to those with intermediate-risk disease (hazards ratio [HR], 1.27; P = .01; HR, 1.71; P < .001, respectively). Leukemia-free survival was similar for patients with KMT2A rearrangement or adverse risk (HR, 1.26; P = .002, and HR, 1.47; P < .001), as was overall survival (HR, 1.32; P < .001, and HR, 1.45; P < .001). No differences in outcome were detected when patients were stratified by KMT2A fusion partner. This study is the largest conducted to date on post-HCT outcomes in AML, with manually curated cytogenetics used for risk stratification. Our work demonstrates that risk classification at diagnosis remains predictive of post-HCT outcomes in AML. It also highlights the critical need to develop novel treatment strategies for patients with KMT2A-rearranged and adverse-risk disease.

The effect of chronic graft-versus-host disease (cGVHD) on the risk of nonrelapse mortality (NRM) and relapse has not been specifically studied in older adults, who are increasingly undergoing allogeneic hematopoietic cell transplantation (alloHCT) and surviving long-term to develop cGVHD. In this Center for International Blood and Marrow Transplant Research (CIBMTR) analysis, we tested our hypothesis that the risk of NRM was higher with the development of cGVHD, particularly among older adults (age ≥60 years). We included 4429 adults age ≥40 years who underwent a first HLA-matched peripheral blood stem cell alloHCT for acute myelogenous leukemia or myelodysplastic syndrome between 2008 and 2017. We compared outcomes of 4 groups—older adults (≥60 years) and younger adults (40 to 59 years) with cGVHD and older and younger adults without cGVHD—to determine the effect of older age and cGVHD on various outcomes. We used Cox proportional hazard models to determine the risk of NRM, relapse, and overall survival (OS). We treated cGVHD as a time-dependent covariate. The severity of cGVHD was based on the CIBMTR clinical definitions. cGVHD was significantly associated with a higher risk of NRM and lower risk of relapse regardless of age. The risk of NRM was higher for older adults versus younger adults. Adults who developed cGVHD as a group had longer OS compared with age-matched cohorts without cGVHD. Older adults had worse OS regardless of cGVHD. Among adults with cGVHD, clinically moderate or severe cGVHD was associated with a significantly higher risk of NRM and lower risk of relapse; severe cGVHD was associated with shorter OS, whereas mild to moderate cGVHD was associated with longer OS. Among both younger and older adults, the development of cGVHD was associated with a higher risk of NRM, lower risk of relapse, and longer OS. Older adults had a higher risk of NRM, but the increased risk of NRM associated with cGVHD did not differ based on age. The development of mild to moderate cGVHD offered the most favorable balance between minimizing NRM and decreasing the risk of relapse. The relapse risk was lowest for adults with severe cGVHD, but high NRM resulted in shorter OS. Developing strategies to avoid clinically severe cGVHD is critically important. © 2021 American Society for Transplantation and Cellular Therapy. Published by Elsevier Inc.

Clinical trials do not routinely capture long-term overall survival (OS) in acute myeloid leukemia (AML). We utilized a large National Cancer Database (NCDB) to determine different factors affecting 10-year OS in AML. For patients, 18-59 years who were treated with chemotherapy only without upfront hematopoietic cell transplant (HCT), younger age, female, CBF AML, higher income, and private insurance conferred higher 10-year OS. Among patients, 18-59 years treated with chemotherapy and upfront HCT, younger age and private insurance conferred higher 10-year OS. In a Cox proportional hazard model, the likelihood of death decreased with younger age, fewer comorbidities, treatment at an academic center, private insurance, and use of multiagent chemotherapy. Our results demonstrate poor long-term OS even among younger patients and highlights disparities in leukemia care based on insurance type.

Positive results from recent clinical trials have significantly expanded current therapeutic options for patients with chronic graft-versus-host disease (GVHD). However, new insights into the associations between clinical characteristics of chronic GVHD, pathophysiologic mechanisms of disease, and the clinical and biological effects of novel therapeutic agents are required to allow for a more individualized approach to treatment. The current report is focused on setting research priorities and direction in the treatment of chronic GVHD. Detailed correlative scientific studies should be conducted in the context of clinical trials to evaluate associations between clinical outcomes and the biological effect of systemic therapeutics. For patients who require systemic therapy but not urgent initiation of glucocorticoids, clinical trials for initial systemic treatment of chronic GVHD should investigate novel agents as monotherapy without concurrently starting glucocorticoids, to avoid confounding biological, pathological, and clinical assessments. Clinical trials for treatment-refractory disease should specifically target patients with incomplete or suboptimal responses to most recent therapy who are early in their disease course. Close collaboration between academic medical centers, medical societies, and industry is needed to support an individualized, biology-based strategic approach to chronic GVHD therapy.

Venetoclax is a highly selective B-cell lymphoma-2 (BCL-2) inhibitor, which, combined with a DNA hypomethylating agent or low dose cytarabine, results in high rates of initial responses in patients with acute myeloid leukemia (AML). However, the disease relapses in most patients. Mechanisms of resistance to venetoclax-based therapy include TP53 gene mutations or inactivation of p53 protein, activating kinase mutations such as FLT3 and RAS, and upregulation of other BCL-2 family apoptotic proteins. Current clinical trials are exploring strategies such as doublet or triplet regimens incorporating a p53 activator, an anti-CD47 antibody, or other novel agents that target genes and proteins responsible for resistance to venetoclax. Further studies should focus on identifying predictive biomarkers of response to venetoclax-based therapy and incorporating immunotherapeutic approaches such as checkpoint inhibitors, bispecific antibodies, antibody-drug conjugates, and CAR T-cell therapy to improve outcomes for patients with AML.

We review how understanding the fitness and comorbidity burden of patients, and molecular landscape of underlying acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) at the time of diagnosis is now integral to treatment.The upfront identification of patients' fitness and molecular profile facilitates selection of targeted and novel agents, enables risk stratification, allows consideration of allogeneic hematopoietic cell transplantation in high-risk patients, and provides treatment selection for older (age ≥ 75) or otherwise unfit patients who may not tolerate conventional treatment. The use of measurable residual disease (MRD) assessment improves outcome prediction and can also guide therapeutic strategies such as chemotherapy maintenance and transplant. In recent years, several novel drugs have received FDA approval for treating patients with AML with or without specific mutations. A doublet and triplet combination of molecular targeted and other novel treatments have resulted in high response rates in early trials. Following the initial success in AML, novel drugs are undergoing clinical trials in MDS. Unprecedented advances have been made in precision medicine approaches in AML and MDS. However, lack of durable responses and long-term disease control in many patients still present significant challenges, which can only be met, to some extent, with innovative combination strategies throughout the course of treatment from induction to consolidation and maintenance.

Understanding the association between insurance status and survival in an evolving US healthcare system remains a challenge but is essential to address healthcare disparities. We utilized National Cancer Database to evaluate the effects of insurance type on one-month mortality and overall survival (OS) in patients with acute promyelocytic leukemia. Among patients lt;65 years, one-month mortality was worse for uninsured patients and patients with Medicare compared to patients with private insurance. OS was similar between patients with private insurance and uninsured patients but worse for patients with Medicare and Medicaid/other government insurance. In multivariate analysis, older age and greater comorbidity burden conferred worse OS. For patients ≥65 years, insurance type did not affect one-month mortality and OS. Older age, greater comorbidity burden, and treatment at non-academic centers conferred worse one-month mortality and OS. Our results highlight healthcare disparities based on insurance types for both younger and older patients.

Acute Myeloid Leukemia (AML) has a median age at diagnosis of 67 years. The most common curative therapy remains an allogeneic hematopoietic stem cell transplantation (HCT), yet it is complicated by treatment-related mortality (TRM) and ongoing morbidity including graft versus host disease (GVHD) that may impact survival, particularly in older patients. We examined the outcomes and predictors of success in 1321 patients aged 60 years and older receiving a HCT for AML in first complete remission (CR1) from 2007-2017 and reported to the CIBMTR. Outcomes were compared in three age cohorts (60-64; 65-69; 70+). With median follow-up of nearly 3 years, patients aged 60-64 had modestly, though significantly better OS, DFS and lower TRM than those either 65-69 or 70+; cohorts with similar outcomes. Three-year OS for the 3 cohorts was 49.4%, 42.3%, and 44.7% respectively (p = 0.026). TRM was higher with increasing age, cord blood as graft source and HCT-CI score of ≥3. Conditioning intensity was not a significant predictor of OS in the 60-69 cohort with 3-year OS of 46% for RIC and 49% for MAC (p = 0.38); MAC was rarely used over age 70. There was no difference in the relapse rate, incidence of Grade III/IV acute GVHD, or moderate-severe chronic GVHD across the age cohorts. After adjusting for other predictors, age had a small effect on OS and TRM. High-risk features including poor cytogenetics and measurable residual disease (MRD) prior to HCT were each significantly associated with relapse and accounted for most of the adverse impact on OS and DFS. Age did not influence the incidence of either acute or chronic GVHD; while graft type and associated GVHD prophylaxis were most important. These data suggest that age alone is not a barrier to successful HCT for AML in CR1 and should not exclude patients from HCT. Efforts should focus on minimizing residual disease and better donor selection.

Acute promyelocytic leukemia (APL) boasts overall survival (OS) of >90% at 3 years and early mortality of 60 years. OS at 1- and 3-year were 81% and 75%, respectively. In a multivariate analysis, age ≤ 40 years, treatment at academic center, use of multi-agent therapy, and diagnosis after 2009 conferred better OS. In this largest database study in APL till date, we demonstrated an overall improvement in OS over time but challenges still exist in translating successes of clinical trials to real-world practices.

The NCCN Guidelines for Acute Myeloid Leukemia (AML) provide recommendations for the diagnosis and treatment of adults with AML based on clinical trials that have led to significant improvements in treatment, or have yielded new information regarding factors with prognostic importance, and are intended to aid physicians with clinical decision-making. These NCCN Guidelines Insights focus on recent select updates to the NCCN Guidelines, including familial genetic alterations in AML, postinduction or postremission treatment strategies in low-risk acute promyelocytic leukemia or favorable-risk AML, principles surrounding the use of venetoclax-based therapies, and considerations for patients who prefer not to receive blood transfusions during treatment.

Successful treatment of pancreatic cancer remains a challenge due to desmoplasia, development of chemoresistance, and systemic toxicity. Herein, we synthesized (6-(3-hydroxy-4-methoxylphenyl)pyridin-2-yl) (3,4,5-trimethoxyphenyl)methanone (CH-3-8), a novel microtubule polymerization inhibitor with little susceptible to transporter-mediated chemoresistance. CH-3-8 binding to the colchicine-binding site in tubulin protein was confirmed by tubulin polymerization assay and molecular modeling. CH-3-8 disrupted microtubule dynamics at the nanomolar concentration in MIA PaCa-2 and PANC-1 pancreatic cancer cell lines. CH-3-8 significantly inhibited the proliferation of these cells, induced G2/M cell cycle arrest, and led to apoptosis. CH-3-8 is hydrophobic with an aqueous solubility of 0.97 ± 0.16 μg/mL at pH 7.4. We further conjugated it with dodecanol through diglycolate linker to increase hydrophobicity and thus loading in lipid-based delivery systems. Hence, we encapsulated CH-3-8 lipid conjugate (LDC) into methoxy poly(ethylene glycol)-block-poly(2-methyl-2-carboxyl-propylene carbonate-graft-dodecanol) (mPEG-b-PCC-g-DC) polymeric nanoparticles (NPs) by solvent evaporation, resulting in a mean particle size of 125.6 ± 2.3 nm and drug loading of 10 ± 1.0% (w/w) while the same polymer could only load 1.6 ± 0.4 (w/w) CH-3-8 using the same method. Systemic administration of 6 doses of CH-3-8 and LDC loaded NPs at the dose of 20 mg/kg into orthotopic pancreatic tumor-bearing NSG mice every alternate day resulted in significant tumor regression. Systemic toxicity was negligible, as evidenced by histological evaluations. In conclusion, CH-3-8 LDC loaded NPs have the potential to improve outcomes of pancreatic cancer by overcoming transporter-mediated chemoresistance and reducing systemic toxicity.

The use of multiagent chemotherapy in acute lymphoblastic leukemia (ALL) has resulted in improvement in overall survival (OS), albeit to a different extent across various age groups. This large database study aims to assess the disparity in the utilization of chemotherapy in ALL in the real-world setting.Using the Surveillance, Epidemiology, and End Results database, patients with ALL diagnosis from 2006 to 2016 were identified. Baseline characteristics were compared between the groups who did vs. did not receive chemotherapy using χOut of 16,196 patients, 1258 patients (8%) did not receive chemotherapy. There was a steady increase in the number of patients who did not receive chemotherapy with advancing age: 2.5% (0-18 years), 5.2% (19-40 years), 9.3% (41-65 years), and 36.2% (65 years). There was an upward trend in the receipt of chemotherapy in patients65 years over the last decade. In multivariate analysis, the likelihood of receiving chemotherapy decreased with advancing age, single or widowed status, low income and educational status, and lack of insurance. Insurance status was an independent predictor of receipt of chemotherapy across each age category.A significant proportion of patients65 years do not receive chemotherapy in the United States. Age, marital status, income, education, and insurance status contribute to the disparity in utilization of chemotherapy.

New therapeutic approaches are needed to improve outcomes of patients with advanced chronic graft vs. host disease (GVHD). Pre-clinical and clinical data suggest proteasome inhibition may modulate GVHD. In a phase II, single-arm, multi-center trial conducted by the Chronic GVHD Consortium, we examined the efficacy of ixazomib in advanced chronic GVHD treatment. Ixazomib was given as a 4 mg oral dose weekly on days 1, 8, and 15 of a 28-day cycle for up to 6 total cycles. An amendment permitted additional cycles beyond 6 for those with responsive chronic GVHD. The primary endpoint was 6 month treatment failure, a composite endpoint including death, relapse, and requirement for an additional line of systemic immune suppressive (IS) therapy, compared with a historical 6 month treatment failure rate of 44% based on 312 patients treated with secondary therapy. Key eligibility criteria included age ≥ 18, NIH Consensus defined chronic GVHD, failure of at least one prior line of systemic IS therapy, and adequate hematologic parameters, hepatic, and renal function. A total of 50 subjects were enrolled at 6 institutions. Median age was 58 years. Median time from transplant to enrollment was 3.6 years (IQR 2.6-5.5), and from chronic GVHD onset to enrollment 2.8 years (IQR 1.5-4.3). Chronic GVHD was NIH moderate (16%) or severe (84%), predominantly classic (80% vs. overlap 20%), with 52% having 4 or more involved organs. Patients were heavily pretreated with 39 (78%) having 3 or more prior lines of systemic therapy for chronic GVHD. Of the 50 treated subjects, 26 completed all 6 months of planned therapy. Dose reductions most commonly occurred for thrombocytopenia, fatigue, diarrhea, and infection. SAEs occurred in 38% of subjects, and 5 deaths occurred in study participants (2 deemed possibly related to ixazomib). The 6 month treatment failure rate was significantly improved vs. the historical benchmark (28% vs. 44%, p=0.01), Figure 1. No patient, transplant, or chronic GVHD variables were significantly associated with 6 month treatment failure. NIH response rates at 3, 6, and 12 months are presented in Figure 2; the ORR was 34% (17/50) at 6 months. Overall survival at 6 and 12 months was 92% and 90%. No subjects completely discontinued IS by 12 months. Ixazomib met the primary endpoint of low treatment failure at 6 months in the setting of advanced chronic GVHD. At 6 months the ORR rate was 34% and 50% remained on ixazomib suggesting the low treatment failure rate was in part due to prevention of progressive disease that would have required additional treatment. Randomized studies are warranted.

Acute myeloid leukemia (AML) is a heterogeneous disease marked by the presence of several driver mutations and molecular subgroups even in a single patient. The genetic and molecular heterogeneity is also reflected by a progressive shift from a morphologic classification to one informed by causative genomic changes. Cytogenetic results and somatic mutations are increasingly being utilized to guide use of intensive chemotherapy and low-intensity chemotherapy, particularly among older adults. Utilization of next generation sequencing in AML has led to increasing use of targeted treatments for actionable mutations. Quantitative real-time polymerase chain reaction based mutational analysis and multicolor flow cytometry offer sensitive assays that can detect minimal residual disease (MRD). Several studies have shown that MRD negativity, as defined by specified cutoff values, is highly prognostic with potential therapeutic implications. The last three years mark an unprecedented history in the drug development in AML with approval of eight new drugs and large portfolio of ongoing early and late phase trials of several promising drugs. Multiple combinatorial trials of approved agents and approval of newer agents in the future will continue to change the therapeutic landscape of AML.

Post-transplant cyclophosphamide (PTCy) has significantly increased the successful use of haploidentical donors with a relatively low incidence of graft-versus-host disease (GVHD). Given its increasing use, we sought to determine risk factors for GVHD after haploidentical hematopoietic cell transplantation (haplo-HCT) using PTCy. Data from the Center for International Blood and Marrow Transplant Research on adult patients with acute myeloid leukemia, acute lymphoblastic leukemia, myelodysplastic syndrome, or chronic myeloid leukemia who underwent PTCy-based haplo-HCT (2013 to 2016) were analyzed and categorized into 4 groups based on myeloablative (MA) or reduced-intensity conditioning (RIC) and bone marrow (BM) or peripheral blood (PB) graft source. In total, 646 patients were identified (MA-BM = 79, MA-PB = 183, RIC-BM = 192, RIC-PB = 192). The incidence of grade 2 to 4 acute GVHD at 6 months was highest in MA-PB (44%), followed by RIC-PB (36%), MA-BM (36%), and RIC-BM (30%) (P = .002). The incidence of chronic GVHD at 1 year was 40%, 34%, 24%, and 20%, respectively (P < .001). In multivariable analysis, there was no impact of stem cell source or conditioning regimen on grade 2 to 4 acute GVHD; however, older donor age (30 to 49 versus

There is a lack of large comparative study on the outcomes of reduced intensity conditioning (RIC) in acute myeloid leukemia (AML) transplantation using fludarabine/busulfan (FB) and fludarabine/melphalan (FM) regimens. Adult AML patients from Center for International Blood and Marrow Transplant Research who received first RIC allo-transplant between 2001 and 2015 were studied. Patients were excluded if they received cord blood or identical twin transplant, total body irradiation in conditioning, or graft-versus-host disease (GVHD) prophylaxis with in vitro T-cell depletion. Primary outcome was overall survival (OS), secondary end points were leukemia-free survival (LFS), nonrelapse mortality (NRM), relapse, and GVHD. Multivariate survival model was used with adjustment for patient, leukemia, and transplant-related factors. A total of 622 patients received FM and 791 received FB RIC. Compared with FB, the FM group had fewer transplant in complete remission (CR), fewer matched sibling donors, and less usage of anti-thymocyte globulin or alemtuzumab. More patients in the FM group received marrow grafts and had transplantation before 2005. OS was significantly lower within the first 3 months posttransplant in the FM group (hazard ratio [HR] = 1.82, P < .001), but was marginally superior beyond 3 months (HR = 0.87, P = .05). LFS was better with FM compared with FB (HR = 0.89, P = .05). NRM was significantly increased in the FM group during the first 3 months of posttransplant (HR = 3.85, P < .001). Long-term relapse was lower with FM (HR = 0.65, P < .001). Analysis restricted to patients with CR showed comparable results. In conclusion, compared with FB, the FM RIC showed a marginally superior long-term OS and LFS and a lower relapse rate. A lower OS early posttransplant within 3 months was largely the result of a higher early NRM.

Use of allogeneic hematopoietic cell transplantation (alloHCT) is increasing in older patients with hematologic malignancies. Studies suggest that geriatric assessment (GA), incorporating functional measures such as instrumental activities of daily living (IADL), delineates subtle age-related impairments that enhance risk-stratification. The objective of this multi-institutional retrospective study was to evaluate the prognostic utility of GA metrics collected pre-alloHCT. Eligibility criteria included age ≥50 and pre-alloHCT GA inclusive of at least IADL. Beyond IADL, additional geriatric metrics were collected where available and included Medical Outcomes Study Physical Health score (MOS-PH), Timed Up and Go (TUG), and cognition by Blessed Orientation Memory Concentration (BOMC). Three hundred thirty subjects were included, with a median age of 63 (range 50 to 77). Impairments were frequent: 36% had at least 1 IADL impairment; 14% had TUG ≥13.5 seconds; and 17% had cognitive impairment (BOMC ≥ 7). Median MOS-PH score was 80. IADL and age were not significantly associated with nonrelapse mortality (NRM) or overall survival (OS). In multivariate analysis, only impaired cognition and Hematopoietic Cell Transplant-Comorbidity Index score ≥3 showed an independent association with 1-year NRM (subdistribution hazard ratio [SHR], 2.36; P = .01; and SHR, 2.19; P = .009, respectively). Cognitive impairment independently conferred inferior 1-year OS (hazard ratio, 1.94; P = .01). In a preplanned subgroup analysis in 224 patients aged ≥60 years, cognitive impairment remained the sole GA metric predictive of NRM (2-year NRM: SHR, 2.72; P = .007). These data suggest that cognitive impairment elevates risk of post-alloHCT NRM in older patients.

Hematopoietic cell transplantation (HCT) involves the infusion of hematopoietic progenitor cells into patients with hematologic disorders with the goal of re-establishing normal hematopoietic and immune function. HCT is classified as autologous or allogeneic based on the origin of hematopoietic cells. Autologous HCT uses the patient’s own cells while allogeneic HCT uses hematopoietic cells from a human leukocyte antigen-compatible donor. Allogeneic HCT is a potentially curative treatment option for patients with certain types of hematologic malignancies, and autologous HCT is primarily used to support patients undergoing high-dose chemotherapy. Advances in HCT methods and supportive care in recent decades have led to improved survival after HCT; however, disease relapse and posttransplant complications still commonly occur in both autologous and allogeneic HCT recipients. Allogeneic HCT recipients may also develop acute and/or chronic graft-versus-host disease (GVHD), which results in immune-mediated cellular injury of several organs. The NCCN Guidelines for Hematopoietic Cell Transplantation focus on recommendations for pretransplant recipient evaluation and the management of GVHD in adult patients with malignant disease.

Polypharmacy, usually defined as taking ≥5 prescribed medications, increases chances of drug–drug interactions and toxicities, and may harm cancer patients who need multiple chemotherapeutic agents and supportive medications. We analyzed the effects of polypharmacy in overall survival (OS) in acute myeloid leukemia (AML). A total of 399 patients were divided into two groups: patients with polypharmacy (≥5 medications) versus without polypharmacy (

Hyperleukocytosis in acute myeloid leukemia (AML) is associated with inferior outcomes. There is limited high quality evidence to support the benefits of leukapheresis. We retrospectively collected data from patients with newly-diagnosed AML who presented with a white cell count (WBC) >50 x 10(9)/L to 12 centers in the United States and Europe from 2006 to 2017 and received intensive chemotherapy. Logistic regression models estimated odds ratios for 30-day mortality and achievement of composite complete remission (CRc). Cox proportional hazard models estimated hazard ratios for overall survival (OS). Among 779 patients, clinical leukostasis was reported in 27%, and leukapheresis was used in 113 patients (15%). Thirty-day mortality was 16.7% (95% CI: 13.9-19.3%). Median OS was 12.6 months (95% CI: 11.5-14.9) among all patients, and 4.5 months (95% CI: 2.7-7.1) among those >= 65 years. Use of leukapheresis did not significantly impact 30-day mortality, achievement of CRc, or OS in multivariate analysis based on available data or in analysis based on multiple imputation. Among patients with investigator-adjudicated clinical leukostasis, there were statistically significant improvements in 30-day mortality and OS with leukapheresis in unadjusted analysis, but not in multivariate analysis. Given the significant resource use, cost, and potential complications of leukapheresis, randomized studies are needed to evaluate its value.

BACKGROUND: The role of obesity in prognosis of acute myeloid leukemia(AML) is debatable. Our retrospective study aimed to determine the effect of obesity on overall survival(OS) in AML. METHODS: AML patients diagnosed at University of Nebraska Medical Center were divided into 3-groups based on body mass index (BMI): normal(18.5-25kg/m(2)) or underweight(
