RESUMO
Clonal cytopenia of undetermined significance (CCUS) represents a distinct disease entity characterized by myeloid-related somatic mutations with a variant allele fraction of ≥2% in individuals with unexplained cytopenia(s) but without a myeloid neoplasm (MN). Notably, CCUS carries a risk of progressing to MN, particularly in cases featuring high-risk mutations. Understanding CCUS requires dedicated studies to elucidate its risk factors and natural history. Our analysis of 357 CCUS patients investigated the interplay between clonality, cytopenia, and prognosis. Multivariate analysis identified 3 key adverse prognostic factors: the presence of splicing mutation(s) (score = 2 points), platelet count <100×109/L (score = 2.5), and ≥2 mutations (score = 3). Variable scores were based on the coefficients from the Cox proportional hazards model. This led to the development of the Clonal Cytopenia Risk Score (CCRS), which stratified patients into low- (score <2.5 points), intermediate- (score 2.5-<5), and high-risk (score ≥5) groups. The CCRS effectively predicted 2-year cumulative incidence of MN for low- (6.4%), intermediate- (14.1%), and high- (37.2%) risk groups, respectively, by Gray's test (P <.0001). We further validated the CCRS by applying it to an independent CCUS cohort of 104 patients, demonstrating a c-index of 0.64 (P =.005) in stratifying the cumulative incidence of MN. Our study underscores the importance of integrating clinical and molecular data to assess the risk of CCUS progression, making the CCRS a valuable tool that is practical and easily calculable. These findings are clinically relevant, shaping the management strategies for CCUS and informing future clinical trial designs.
RESUMO
Myelodysplastic syndromes/myelodysplastic neoplasms (MDS) are associated with variable clinical presentations and outcomes. The initial response criteria developed by the International Working Group (IWG) in 2000 have been used in clinical practice, clinical trials, regulatory reviews, and drug labels. Although the IWG criteria were revised in 2006 and 2018 (the latter focusing on lower-risk disease), limitations persist in their application to higher-risk MDS (HR-MDS) and their ability to fully capture the clinical benefits of novel investigational drugs or serve as valid surrogates for longer-term clinical end points (eg, overall survival). Further, issues related to the ambiguity and practicality of some criteria lead to variability in interpretation and interobserver inconsistency in reporting results from the same sets of data. Thus, we convened an international panel of 36 MDS experts and used an established modified Delphi process to develop consensus recommendations for updated response criteria that would be more reflective of patient-centered and clinically relevant outcomes in HR-MDS. Among others, the IWG 2023 criteria include changes in the hemoglobin threshold for complete remission (CR), the introduction of CR with limited count recovery and CR with partial hematologic recovery as provisional response criteria, the elimination of marrow CR, and specific recommendations for the standardization of time-to-event end points and the derivation and reporting of responses. The updated criteria should lead to a better correlation between patient-centered outcomes and clinical trial results in an era of multiple emerging new agents with novel mechanisms of action.

The safety and efficacy of sabatolimab, a novel immunotherapy targeting T-cell immunoglobulin domain and mucin domain-3 (TIM-3), was assessed in combination with hypomethylating agents (HMAs) in patients with HMA-naive revised International Prognostic System Score (IPSS-R) high- or very high-risk myelodysplastic syndromes (HR/vHR-MDS) or chronic myelomonocytic leukemia (CMML). Sabatolimab + HMA had a safety profile similar to that reported for HMA alone and demonstrated durable clinical responses in patients with HR/vHR-MDS. These results support the ongoing evaluation of sabatolimab-based combination therapy in MDS, CMML, and acute myeloid leukemia.

INTRODUCTION: Patients with myeloproliferative neoplasms (MPNs) and atrial fibrillation (AF) are at increased risk of thrombosis and bleeding. However, the risk of thrombosis and bleeding in patients with AF and MPN compared with the general population with AF is unclear. Additionally, traditional risk scores (CHA2DS2-VASC and HAS-BLED) for risk/benefit estimation of thromboprophylaxis in AF do not account for MPN status. Therefore, we aimed to investigate bleeding and thrombosis risk in patients with MPN hospitalized for AF. METHODS: We utilized the National Readmission Database (NRD) to identify patients with AF with and without MPN. Primary bleeding and thrombosis outcomes were in-hospital or 30-day readmission for bleeding or thrombosis, respectively. We propensity score (PS) matched patients with and without MPN. Risk of primary outcomes in MPN was assessed in PS matched cohort using logistic regression. Receiver operating characteristic (ROC) curve used to evaluate predictive ability of CHA2DS2-VASC and HAS-BLED of primary thrombosis and bleeding outcomes, respectively. RESULTS: 24,185 patients without MPN were matched with 1,617 patients with MPN and variables were balanced between groups. Patients with MPN were at increased risk of meeting the thrombosis (OR 1.98, 95% CI 1.23-3.21) but not bleeding (OR 0.87, 95% CI 0.63-1.19) primary outcomes. In MPN, CHA2DS2-VASC predicted thrombosis (C-statistic 0.66, 95% CI 0.54-0.78) but HAS-BLED was a poor predictor of bleeding (C-statistic 0.55, 95% CI 0.46-0.64). CONCLUSION: In patients with AF, MPN was associated with increased risk of bleeding and thrombosis. HAS-BLED scores did not accurately predict bleeding in MPN. Further investigation is needed to refine risk scores in MPN.

PURPOSE OF REVIEW: Therapies that target the immune system are increasingly used across oncology, including in hematologic malignancies such as myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML). While allogeneic transplant has been a key therapy in these cancers, new approaches that target the immune system are being explored including immune checkpoint therapies, antibody-drug conjugates, and cellular therapies. RECENT FINDINGS: This review outlines updates in the preclinical rationale for immune directed therapies in MDS and AML, as well as recent clinical trials exploring these therapies. This manuscript summarizes the development of therapies targeting T cell immunoglobulin and mucin domain-containing protein 3 (TIM-3) and CD47, which are being evaluated in late phase studies in MDS and AML. It also reviews the landscape of other immune based therapies including antibody-drug conjugates, chimeric antigen receptor-T cells, bispecific antibodies, and tumor vaccines. SUMMARY: The treatment landscape in MDS and AML is rapidly changing; with a goal of improving the quality and duration of responses, a number of immune based therapies are under investigation. This review outlines recent advances with these therapies as well as some of the challenges that remain to incorporate them into leukemia care.

BACKGROUND: Patients with acute myeloid leukemia (AML) experience a substantial decline in quality of life (QoL) and mood during their hospitalization for intensive chemotherapy, yet few interventions have been developed to enhance patient-reported outcomes during treatment. METHODS: We conducted a pilot randomized trial (ClinicalTrials.gov identifier NCT03372291) of DREAMLAND, a psychological mobile application for patients with a new diagnosis of AML who are receiving intensive chemotherapy. Patients were randomly assigned to DREAMLAND or usual care. DREAMLAND included four required modules focused on: (1) supportive psychotherapy to help patients deal with the initial shock of diagnosis, (2) psychoeducation to manage illness expectations, (3) psychosocial skill-building to promote effective coping, and (4) self-care. The primary end point was feasibility, which was defined as ≥60% of eligible patients enrolling and 60% of those enrolled completing ≥60% of the required modules. We assessed patient QoL (the Functional Assessment of Cancer Therapy-Leukemia), psychological distress (the Hospital Anxiety and Depression Scale and the Patient Health Questionnaire-9), symptom burden (the Edmonton Symptom Assessment Scale), and self-efficacy (the Cancer Self-Efficacy Scale) at baseline and at day 20 after postchemotherapy. RESULTS: We enrolled 60 of 90 eligible patients (66.7%), and 62.1% completed ≥75% of the intervention modules. At day 20 after chemotherapy, patients who were randomized to DREAMLAND reported improved QoL scores (132.06 vs. 110.72; p =.001), lower anxiety symptoms (3.54 vs. 5.64; p = .010) and depression symptoms (Hospital Anxiety and Depression Scale: 4.76 vs. 6.29; p = .121; Patient Health Questionnaire-9: 4.62 vs. 8.35; p < .001), and improved symptom burden (24.89 vs. 40.60; p = .007) and self-efficacy (151.84 vs. 135.43; p = .004) compared with the usual care group. CONCLUSIONS: A psychological mobile application for patients with newly diagnosed AML is feasible to integrate during hospitalization for intensive chemotherapy and may improve QoL, mood, symptom burden, and self-efficacy.

Less-intensive induction therapies are increasingly used in older patients with acute myeloid leukemia (AML). Using an AML composite model (AML-CM) assigning higher scores to older age, increased comorbidity burdens, and adverse cytogenetic risks, we defined 3 distinct prognostic groups and compared outcomes after less-intensive vs intensive induction therapies in a multicenter retrospective cohort (n = 1292) treated at 6 institutions from 2008 to 2012 and a prospective cohort (n = 695) treated at 13 institutions from 2013 to 2017. Prospective study included impacts of Karnofsky performance status (KPS), quality of life (QOL), and physician perception of cure. In the retrospective cohort, recipients of less-intensive therapies were older and had more comorbidities, more adverse cytogenetics, and worse KPS. Less-intensive therapies were associated with higher risks of mortality in AML-CM scores of 4 to 6, 7 to 9, and ≥10. Results were independent of allogeneic transplantation and similar in those age 70 to 79 years. In the prospective cohort, the 2 groups were similar in baseline QOL, geriatric assessment, and patient outcome preferences. Higher mortality risks were seen after less-intensive therapies. However, in models adjusted for age, physician-assigned KPS, and chance of cure, mortality risks and QOL were similar. Less-intensive therapy recipients had shorter length of hospitalization (LOH). Our study questions the survival and QOL benefits (except LOH) of less-intensive therapies in patients with AML, including those age 70 to 79 years or with high comorbidity burdens. A randomized trial in older/medically infirm patients is required to better assess the value of less-intensive and intensive therapies or their combination. This trial was registered at www.clinicaltrials.gov as #NCT01929408.

Patients with relapsed/refractory (R/R) higher-risk myelodysplastic syndromes (MDS) have a dismal median overall survival (OS) after failing hypomethylating agent (HMA) treatment. There is no standard of care for patients after HMA therapy failure; hence, there is a critical need for effective therapeutic strategies. Herein, we present the safety and efficacy of venetoclax + azacitidine in patients with R/R MDS. This phase 1b, open-label, multicenter study enrolled patients ≥18 years. Patients were treated with escalating doses of oral venetoclax: 100, 200, or 400 mg daily for 14 days every 28-day cycle. Azacitidine was administered on Days 1-7 every cycle at 75 mg/m2 /day intravenously/subcutaneously. Responses were assessed per modified 2006 International Working Group (IWG) criteria. Forty-four patients (male 86%, median age 74 years) received venetoclax + azacitidine treatment. Median follow-up was 21.2 months. Hematological adverse events of Grade ≥ 3 included febrile neutropenia (34%), thrombocytopenia (32%), neutropenia (27%), and anemia (18%). Pneumonia (23%) was the most common Grade ≥ 3 infection. Marrow responses were seen including complete remission (CR, n = 3, 7%) and marrow CR (mCR, n = 14, 32%); 36% (16/44) achieved transfusion independence (TI) for RBCs and/or platelets, and 43% (6/14) with mCR achieved hematological improvement (HI). The median time to CR/mCR was 1.2 months, and the median duration of response for CR + mCR was 8.6 months. Median OS was 12.6 months. Venetoclax + azacitidine shows activity in patients with R/R MDS following prior HMA therapy failure and provides clinically meaningful benefits, including HI and TI, and encouraging OS.

BCR-ABL1 kinase inhibitors have improved the prognosis of Philadelphia-chromosome-positive (Ph+)-acute lymphoblastic leukemia (ALL). Ph-like (or BCR-ABL1-like) ALL does not express BCR-ABL1 but commonly harbors other genomic alterations of signaling molecules that may be amenable to therapy. Here, we report a case with a NUP214-ABL1 fusion detected at relapse by multiplexed, targeted RNA sequencing. It had escaped conventional molecular work-up at diagnosis, including cytogenetic analysis and fluorescence in situ hybridization for ABL1 rearrangements. The patient had responded poorly to initial multi-agent chemotherapy and inotuzumab immunotherapy at relapse before the fusion was revealed. The addition of dasatinib targeting NUP214-ABL1 to inotuzumab resulted in complete molecular remission, but recurrence occurred rapidly with dasatinib alone. However, deep molecular remission was recaptured with a combination of blinatumomab and ponatinib, so he could proceed to allotransplantation. This case illustrates that next-generation sequencing approaches designed to discover cryptic gene fusions can benefit patients with Ph-like ALL.

AIMS: TP53-mutated acute myeloid leukaemia (AML) is associated with an adverse prognosis and poor response to traditional chemotherapy regimens. Next-generation sequencing (NGS) is considered the gold standard method to determine TP53-mutational status; however, molecular assays are costly and time-consuming. In contrast, immunohistochemistry (IHC) can be performed within 1 day of biopsy. We sought to determine an optimal threshold of staining with p53 IHC to predict TP53-mutational status. METHODS AND RESULTS: We identified 142 consecutive patients with newly diagnosed AML with concurrent NGS analysis diagnosed between 2019 and 2020. All cases were stained for p53 IHC and images were scored for the percent of strongly stained p53+ cells by a combination of manual counting and image analysis. We then correlated percent positive staining with mutational status and clinical outcomes. We determined that a threshold of ≥7% strongly stained cells by p53 IHC correlated with the presence of a TP53 mutation with a sensitivity of 67%, specificity of 100%, positive predictive value of 100% and negative predictive value of 90%. TP53 mutation and the presence of ≥7% staining by IHC were associated with shorter overall survival by univariate analysis (P < 0.01). CONCLUSION: If the limitations of this study are carefully considered, our findings suggest that p53 protein expression as evaluated by IHC could be used to rapidly predict TP53-mutational status with high specificity and assist in risk stratification in newly diagnosed AML.

Acute lymphoblastic leukemia (ALL) can relapse in the extramedullary compartment, with or without medullary involvement. Response to treatment may be individual. We evaluated response to inotuzumab ozogamicin in 31 patients with relapsed/refractory B-ALL with extramedullary disease. Median age was 31 years (range, 19-81). All patients were heavily pretreated, including allogeneic hematopoietic stem cell transplantation (HSCT; n=18). Overall response rate after two cycles of inotuzumab ozogamicin was 84% (complete remission, 55%; partial remission, 29%; resistant disease, 13%; early death, 3%). The median follow-up was 29 months and median overall survival was 12.8 months. One-year and 2-year overall survival rates were 53% (95% CI: 37-76%) and 18% (95% CI: 8-43%), respectively. Age had no impact on overall survival when assessed as a continuous variable or dichotomized at 60 years. Twelve patients proceeded to allogeneic HSCT (complete remission, n=6; partial remission, n=3; resistant disease, n=3). Prior to allogeneic HSCT, eight patients received two or fewer cycles and four patients received three or four cycles of inotuzumab ozogamicin. Sinusoidal obstruction syndrome was reported in three patients, including one after transplantation. Allogeneic HSCT, evaluated as a time-dependent variable, had no impact on overall survival. Inotuzumab ozogamicin seems to be effective as a debulking strategy in relapsed/refractory ALL with extramedullary disease. However, inotuzumab ozogamicin followed by allogeneic HSCT seems not to be effective in maintaining long-term disease control.

The aim of this study was to evaluate the prognostic impact of FLT3-ITD in core-binding factor acute myeloid leukemia (CBFAML) in an international, multicenter survey of 97 patients of whom 52% had t(8;21)(q22;q22) and 48% had inv(16)(p13q22)/t(16;16)(p13;q22). The median age of the patients was 53 years (range, 19-81). Complete remission after anthracycline-based induction (n=86) and non-intensive therapy (n=11) was achieved in 97% and 36% of the patients, respectively. The median follow-up was 4.43 years (95% confidence interval [95% CI]: 3.35-7.39 years). The median survival after intensive and non-intensive treatment was not reached and 0.96 years, respectively. Among intensively treated patients, inv(16) with trisomy 22 (n=11) was associated with a favorable 4-year relapse-free survival rate of 80% (95% CI: 59-100%) as compared to 38% (95% CI: 27-54%; P=0.02) in all other patients with CBFAML/ FLT3-ITD (n=75). Overall, 24 patients underwent allogeneic hematopoietic cell transplantation (HCT), 12 in first complete remission and 12 after relapse. Allogeneic HCT in first complete remission was not beneficial (P=0.60); however, allogeneic HCT seemed to improve median survival in relapsed patients compared to that of patients treated with chemotherapy (not reached vs. 0.6 years, respectively; P=0.002). Excluding patients with inv(16) with trisomy 22, our data indicate that compathe outcome of CBF-AML patients with FLT3-ITD may be inferior to that of patients without FLT3-ITD (based on previously published data), suggesting that prognostically CBF-AML patients with FLT3-ITD should not be classified as favorable-risk. FLT3-inhibitors may improve the outcome of these patients.

BACKGROUND: Patients with acute myeloid leukemia (AML) face an abrupt life-threatening illness and experience immense physical and psychological symptoms. However, no data describe how patients with AML cope longitudinally with their illness or the relationship between longitudinal coping and outcomes. METHODS: We conducted a secondary analysis of longitudinal data from 160 patients with high-risk AML enrolled in a supportive care intervention trial to describe coping strategies longitudinally across the illness course. We used the Brief COPE questionnaire, the Hospital Anxiety and Depression Scale, the Post-Traumatic Stress Disorder (PTSD) Checklist-Civilian Version, and the Functional Assessment of Cancer Therapy-Leukemia to measure coping strategies, psychological distress, and quality of life (QoL) at baseline and at weeks 2, 4, 12, and 24 after diagnosis. Electronic health records were used to assess healthcare utilization and end-of-life (EoL) outcomes, and multivariate analyses were used to assess the relationship between coping and outcomes. RESULTS: Longitudinal utilization of approach-oriented coping strategies was significantly associated with less distress (anxiety: ß, -0.18; P<.001; depression symptoms: ß, -0.42; P<.001; PTSD symptoms: ß, -0.60; P<.001) and better QoL (ß, 2.00; P<.001). Longitudinal utilization of avoidant coping strategies was significantly associated with greater distress (anxiety: ß, 0.64; depression symptoms: ß, 0.54; PTSD symptoms: ß, 2.13; P<.001 for all) and worse QoL (ß, -4.27; P<.001). Although the use of approach-oriented and avoidant coping strategies was not significantly associated with hospitalization, chemotherapy administration, or hospice use in the last 30 days of life, approach-oriented coping was associated with lower odds of ICU admissions (odds ratio, 0.92; P=.049). CONCLUSIONS: Longitudinal use of approach-oriented coping strategies was associated with less psychological distress, better QoL, and a lower likelihood of ICU admission, suggesting a possible target for supportive oncology interventions. Coping strategies did not impact EoL outcomes, and further research is needed to elucidate which patient factors impact EoL decision-making.

LAY SUMMARY: People who have advanced myelodysplastic syndromes (MDS) may live longer if they get a bone marrow transplant (BMT) instead of other therapies. However, only 15% of people with MDS actually get BMT. Experts say community physicians and transplant physicians should team up with insurance companies and patient advocacy groups to 1) spread this news about lifesaving advances in BMT, 2) ensure that everyone can afford health care, 3) provide emotional support for patients and families, 4) help patients and families get transportation and housing if they need to travel for transplant, and 5) improve care for people of under-represented racial and ethnic backgrounds.

BACKGROUND: It has been shown previously that integrated palliative care for patients with acute myeloid leukemia (AML) during intensive chemotherapy leads to improvements in quality of life (QOL) and mood. Coping has been shown to mediate palliative care interventions in advanced cancer; the mechanisms by which improvements occur among patients with AML remain unexplained. METHODS: The authors conducted a secondary analysis of data from a multisite randomized trial of integrated palliative and oncology care (IPC; n = 86) versus usual care (n = 74) for hospitalized patients with AML undergoing intensive chemotherapy. IPC patients met with palliative care at least twice weekly during their initial and subsequent hospitalizations. Patients completed the Functional Assessment of Cancer Therapy-Leukemia, the Hospital Anxiety and Depression Scale, and the Brief Coping Orientation to Problems Experienced Inventory to assess QOL, mood, and coping at the baseline and at weeks 2, 4, 12, and 24. Linear regression models were used to assess the effect of IPC on coping. Causal mediation regression models were used to examine whether changes in coping mediated intervention effects on patient-reported outcomes at week 2. RESULTS: One hundred sixty eligible patients (68.1%) were enrolled. Those randomized to IPC reported improvements in approach-oriented coping (P < .01) and reductions in avoidant coping (P < .05). These changes in coping mediated the intervention effects on QOL (95% CI, 2.14-13.63), depression (95% CI, -2.05 to -0.27), and anxiety symptoms (95% CI, -1.25 to -0.04). Changes in approach-oriented and avoidant coping accounted for 78% of the total palliative care intervention effect on QOL, for 66% of the effect on depression, and for 35% of the effect on anxiety symptoms. CONCLUSIONS: Palliative care integrated during intensive chemotherapy for patients with AML facilitates coping strategy use. Improvement in coping skills accounts for a substantial proportion of the effect from a palliative care intervention on patient-reported outcomes.

BACKGROUND: Patients with acute myeloid leukemia (AML) receiving intensive chemotherapy face a life-threatening illness, isolating hospitalization, and substantial physical and psychological symptoms. However, data are limited regarding risk factors of posttraumatic stress disorder (PTSD) symptoms in this population. METHODS: The authors conducted a secondary analysis of data from 160 patients with high-risk AML who were enrolled in a supportive care trial. The PTSD Checklist-Civilian Version was used to assess PTSD symptoms at 1 month after AML diagnosis. The Brief COPE and the Functional Assessment of Cancer Therapy-Leukemia were to assess coping and quality of life (QOL), respectively. In addition, multivariate regression models were constructed to assess the relation between PTSD symptoms and baseline sociodemographic factors, coping, and QOL. RESULTS: Twenty-eight percent of patients reported PTSD symptoms, describing high rates of intrusion, avoidance, and hypervigiliance. Baseline sociodemographic factors significantly associated with PTSD symptoms were age (B = -0.26; P = .002), race (B = -8.78; P = .004), and postgraduate education (B = -6.30; P = .029). Higher baseline QOL (B = -0.37; P ≤ .001) and less decline in QOL during hospitalization (B = -0.05; P = .224) were associated with fewer PTSD symptoms. Approach-oriented coping (B = -0.92; P = .001) was associated with fewer PTSD symptoms, whereas avoidant coping (B = 2.42; P ≤ .001) was associated with higher PTSD symptoms. CONCLUSIONS: A substantial proportion of patients with AML report clinically significant PTSD symptoms 1 month after initiating intensive chemotherapy. Patients' baseline QOL, coping strategies, and extent of QOL decline during hospitalization emerge as important risk factors for PTSD, underscoring the need for supportive oncology interventions to reduce the risk of PTSD in this population.

In acute myeloid leukaemia (AML) t(8;16)(p11;p13)/MYST3-CREBBP is a very rare abnormality. Previous small series suggested poor outcome. We report on 59 patients with t(8;16) within an international, collaborative study. Median age was 52 (range: 16-75) years. AML was de novo in 58%, therapy-related (t-AML) in 37% and secondary after myelodysplastic syndrome (s-AML) in 5%. Cytogenetics revealed a complex karyotype in 43%. Besides MYST3-CREBBP, whole-genome sequencing on a subset of 10 patients revealed recurrent mutations in ASXL1, BRD3, FLT3, MLH1, POLG, TP53, SAMD4B (n = 3, each), EYS, KRTAP9-1 SPTBN5 (n = 4, each), RUNX1 and TET2 (n = 2, each). Complete remission after intensive chemotherapy was achieved in 84%. Median follow-up was 5·48 years; five-year survival rate was 17%. Patients with s-/t-AML (P = 0·01) and those with complex karyotype (P = 0·04) had an inferior prognosis. Allogeneic haematopoietic cell transplantation (allo-HCT) was performed in 21 (36%) patients, including 15 in first complete remission (CR1). Allo-HCT in CR1 significantly improved survival (P = 0·04); multivariable analysis revealed that allo-HCT in CR1 was effective in de novo AML but not in patients with s-AML/t-AML and less in patients exhibiting a complex karyotype. In summary, outcomes of patients with t(8;16) are dismal with chemotherapy, and may be substantially improved with allo-HCT performed in CR1.

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is an uncommon hematologic malignancy with poor outcomes. Existing data on the clinical behavior of BPDCN are limited because reported outcomes are from small retrospective series, and standardized treatment guidelines are lacking. The interleukin-3 cytotoxin conjugate tagraxofusp was recently tested in phase 1/2 trials that led to US Food and Drug Administration approval, the first ever for BPDCN. However, because there was no matched internal comparator in this or any clinical study to date, results of BPDCN trials testing new drugs are difficult to compare with alternative therapies. We therefore sought to define the clinical characteristics and outcomes of a group of patients with BPDCN treated at 3 US cancer centers in the modern era but before tagraxofusp was available. In 59 studied patients with BPDCN, the median overall survival from diagnosis was 24 months, and outcomes were similar in patients with "skin only" or with systemic disease at presentation. Intensive first-line therapy and "lymphoid-type" chemotherapy regimens were associated with better outcomes. Only 55% of patients received intensive chemotherapy, and 42% of patients underwent stem cell transplantation. Clinical characteristics at diagnosis associated with poorer outcomes included age >60 years, abnormal karyotype, and terminal deoxynucleotidyltransferase (TdT) negativity in the BPDCN cells. We also identified disease responses to pralatrexate and enasidenib in some patients. This study highlights poor outcomes for patients with BPDCN in the modern era and the need for new treatments. Outcomes from ongoing clinical trials for BPDCN can be evaluated relative to this contemporary cohort.

BACKGROUND: The development of novel therapies for the myelodysplastic syndromes (MDS) is hampered by inadequate trial recruitment. Factors contributing to low trial accrual are incompletely understood. METHODS: This study analyzed a pooled patient database from institutions of the US MDS Clinical Research Consortium to compare the characteristics of participants in interventional trials with those of patients who did not enroll in a trial. RESULTS: Data were identified for 1919 patients with MDS, and 449 of these patients (23%) participated in an interventional clinical trial. The median age of all patients was 68 years, and 64% were male. Patients who participated in trials were significantly younger than nonparticipants (P = .014), and men were more likely to participate in a trial (71% of trial participants were male, whereas 61% of nonparticipants were; P < .001). Race and ethnicity were not associated with trial enrollment. Patients in more affluent ZIP codes had a higher participation rate (P < .001). Patients with intermediate- and high-risk disease according to the revised International Prognostic Scoring System were overrepresented (P = .004), and trial participants less frequently had treatment-related disease (P < .001). In multivariable analyses, participation in a clinical trial was associated with a reduced hazard of death (P = .004). Even at large referral centers, only a minority of patients with MDS enrolled in interventional trials. CONCLUSIONS: Restrictive trial eligibility criteria that exclude patients with MDS on account of age, comorbidities, or a history of another cancer are limit enrollment of MDS patients to clinical trials. Gaining insight into the barriers to trial accrual may help investigators and study sponsors to design trials that will accrue more rapidly and augment treatment options for patients with MDS.
