Abstract
Management of higher-risk myelodysplastic syndromes (HR-MDS) is challenging in the real world. We studied 200 patients with HR-MDS within a large US community hospital network. We describe the clinical presentation, patient-related factors, prognostic characteristics, treatment patterns, clinical outcomes and resource utilization. Patients with HR-MDS, treated in our community setting, were elderly (median age 76 years) with a high comorbidity burden. First-line therapy was hypomethylating agent (HMA) monotherapy (20%), lenalidomide (2%), and venetoclax (2%), while the rest were treated with supportive care. Sixty-one percent of the 200, were subsequently hospitalized within 6 months of initial diagnosis. Overall survival was 11.8 months. Curative transplantation was infrequent, HMA-based therapy was underutilized, responses were not durable, most patients became transfusion-dependent or transformed to AML, and resource utilization was substantial and was highly correlated with total in-hospital days. There is a clear unmet need for tolerable treatments that can produce durable remissions in this population.

Transplantation Referral Patterns for Patients with Newly Diagnosed Higher-Risk Myelodysplastic Syndromes and Acute Myeloid Leukemia at Academic and Community Sites in the Connect® Myeloid Disease Registry: Potential Barriers to Care. Transplant Cell Ther 2023; 29:460.e1-460.e9.

Abstract
Hematopoietic stem cell transplantation (HCT) is indicated for patients with higher-risk (HR) myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML). Age, performance status, patient frailty, comorbidities, and nonclinical factors (eg, cost, distance to site) are all recognized as important clinical factors that can influence HCT referral patterns and patient outcomes; however, the proportion of eligible patients referred for HCT in routine clinical practice is largely unknown. This study aimed to assess patterns of consideration for HCT among patients with HR-MDS and AML enrolled in the Connect® Myeloid Disease Registry at community/government (CO/GOV)- or academic (AC)-based sites, as well as to identify factors associated with rates of transplantation referral. We assessed patterns of consideration for and completion of HCT in patients with HR-MDS and AML enrolled between December 12, 2013, and March 6, 2020, in the Connect Myeloid Disease Registry at 164 CO/GOV and AC sites. Registry sites recorded whether patients were considered for transplantation at baseline and at each follow-up visit. The following answers were possible: "considered potentially eligible," "not considered potentially eligible," or "not assessed." Sites also recorded whether patients subsequently underwent HCT at each follow-up visit. Rates of consideration for HCT between CO/GOV and AC sites were compared using multivariable logistic regression analysis with covariates for age and comorbidity. Among the 778 patients with HR-MDS or AML enrolled in the Connect Myeloid Disease Registry, patients at CO/GOV sites were less likely to be considered potentially eligible for HCT than patients at AC sites (27.9% versus 43.9%; P < .0001). Multivariable logistic regression analysis with factors for age (<65 versus ≥65 years) and ACE-27 comorbidity grade (<2 versus ≥2) showed that patients at CO/GOV sites were significantly less likely than those at AC sites to be considered potentially eligible for HCT (odds ratio, 1.6, 95% confidence interval, 1.1 to 2.4; P = .0155). Among patients considered eligible for HCT, 45.1% (65 of 144) of those at CO/GOV sites and 35.7% (41 of 115) of those at AC sites underwent transplantation (P = .12). Approximately one-half of all patients at CO/GOV (50.1%) and AC (45.4%) sites were not considered potentially eligible for HCT; the most common reasons were age at CO/GOV sites (71.5%) and comorbidities at AC sites (52.1%). Across all sites, 17.4% of patients were reported as not assessed (and thus not considered) for HCT by their treating physician (20.7% at CO/GOV sites and 10.7% at AC sites; P = .0005). These findings suggest that many patients with HR-MDS and AML who may be candidates for HCT are not receiving assessment or consideration for transplantation in clinical practice. In addition, treatment at CO/GOV sites and age remain significant barriers to ensuring that all potentially eligible patients are assessed for HCT.

Economic Impact of Transformation to Acute Myeloid Leukemia Among Actively Managed Patients with Higher-Risk Myelodysplastic Syndromes in the United States. Adv Ther 2023; 40:1655-1669. [PMID: 36422807 PMCID: PMC10070206 DOI: 10.1007/s12325-022-02370-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2022] [Accepted: 10/24/2022] [Indexed: 11/26/2022]
Abstract
INTRODUCTION Transformation of higher-risk myelodysplastic syndromes (MDS) to acute myeloid leukemia (AML) may be associated with increased healthcare resource utilization (HCRU) and costs. To describe this economic impact, HCRU and costs were compared between US patients who experienced transformation to AML and those who did not. METHODS Using the Optum administrative claims data, this retrospective matched cohort study identified patients (≥ 18 years old) with higher-risk MDS who initiated first-line therapy between January 1, 2008, and June 30, 2019. Patients whose disease transformed to AML were matched 1:1 to patients whose disease did not transform, based on the duration of follow-up. The follow-up period was divided into two periods: pre- (before transformation to AML) and post-AML (after transformation to AML). For patients who did not transform to AML, pre- and post-AML periods were determined using the transformation date of their matched pair. HCRU and total adjusted costs (2019 US dollars, $) were compared between patients who transformed to AML and those who did not. RESULTS A total of 118 matched patient pairs were included in the study. The hospitalization rate was significantly higher in patients who transformed than in those who did not during the entire follow-up (58.8% vs. 44.1%; P = 0.0295) and post-AML (47.5% vs. 28.0%; P = 0.0028) periods. Across all periods, supportive care use was significantly higher among patients who transformed to AML vs. patients who did not transform. Adjusted mean monthly costs for patients with higher-risk MDS who transformed to AML were higher than those who did not transform ($25,964 vs. $19,150; P < 0.0001). The observed total cost difference was more notable in the post-AML period ($36,424 vs. $14,860; P < 0.0001). CONCLUSIONS Patients with higher-risk MDS whose disease transformed to AML incurred significantly higher healthcare costs compared to those whose disease did not transform, highlighting the important need for treatments that prevent or delay transformation.

Abstract
Patients with acute myeloid leukemia (AML) who have failed hypomethylating agents (HMA) have a poor prognosis. We examined whether high intensity induction chemotherapy could abrogate negative outcomes in 270 patients with AML or other high-grade myeloid neoplasms. Prior HMA therapy was significantly associated with a lower overall survival (OS) as compared to a reference group of patients with secondary disease without prior HMA therapy (median 7.2 vs 13.1 months). In patients with prior HMA therapy, high intensity induction was associated with a non-significant trend toward longer OS (median 8.2 vs 4.8 months) and decreased rates of treatment failure (39% vs 64%). These results redemonstrate poor outcomes in patients with prior HMA and suggest possible benefit of high intensity induction that should be evaluated in future studies.

Abstract
Myelodysplastic syndromes are hematological malignancies characterized by ineffective hematopoiesis and a high risk of progression to acute myeloid leukemia. Hypomethylating agents (HMAs), azacitidine and decitabine, are standard of care therapy for higher-risk myelodysplastic syndromes. However, outcomes reported for real-world studies fall short of those achieved in clinical trials. We conducted a targeted literature review exploring real-world utilization, persistence and outcomes with intravenous and subcutaneous HMA therapies to better understand barriers to achieving optimal outcomes in clinical practice. The potential benefits of oral HMA therapy were also explored. Underutilization and poor persistence with HMA therapy are associated with suboptimal outcomes, highlighting the need for approaches to improve utilization and persistence, so that patients achieve the optimum benefit from HMA therapy.
