Economic burden during remission and after relapse among older patients with newly diagnosed acute myeloid leukemia without hematopoietic stem cell transplant: A retrospective study using the SEER-Medicare database. Leuk Res 2023; 132:107353. [PMID: 37562330 DOI: 10.1016/j.leukres.2023.107353] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2022] [Revised: 06/13/2023] [Accepted: 07/08/2023] [Indexed: 08/12/2023]
Abstract
Acute myeloid leukemia (AML) is associated with a substantial clinical and economic burden. This study characterized the magnitude of this burden following initial treatment with standard or less intensive therapies (hypomethylating agents [HMAs]) and throughout different treatment phases post-remission. The Surveillance, Epidemiology, and End Results (SEER) cancer registry (2007-2016) linked with Medicare beneficiary claims (2007-2015) was analyzed. Patients were ≥ 65 years old with AML who initiated chemotherapy or HMAs and achieved remission. Outcomes included baseline characteristics, treatment patterns, clinical outcomes, healthcare resource utilization (HRU), and costs (2019 United States dollar). Economic impacts were stratified by treatment phase (initial treatment, early post-remission, late post-remission, and post-relapse). Early and late post-remission were defined as treatment initiated ≤ 60 days and > 60 days following initial treatment, respectively. A subgroup analysis of patients receiving only HMAs as initial treatment was also conducted. Overall, 530 patients were included (mean age: 74.1 years; 53.6 % male). In the overall analysis, 68.1 % of patients received post-remission treatment; 31.9% had no post-remission treatment. Mean monthly per patient healthcare costs by treatment phase were $45,747 (initial treatment), $30,248 (early post-remission), $23,173 (late post-remission), and $37,736 (post-relapse), driven predominantly by inpatient visits. The HMA subgroup analysis comprised 71 patients (mean age: 78.8 years; 50.7 % male); mean monthly per patient healthcare costs were highest post-relapse. The economic burden of AML among older patients is substantial across all treatment phases. AML treatments that induce and prolong remission may reduce HRU and the economic burden of disease.

Abstract
Financial toxicity (FT) is a term used to describe the objective financial burden of cancer care including the associated coping behaviors used by patients and their caregivers. FT has been shown to result in both direct financial burdens and in clinically relevant outcomes, such as non-adherence with care, diminished quality of life, and even decreased overall survival. Much of the data has been described in solid tumors, with limited investigations in the malignant hematology population. Patients with hematologic malignancies undergoing hematopoietic stem cell transplantation (HSCT) face a unique financial burden driven by lengthy hospitalizations and acute and chronic morbidity that have downstream implications on their income and costs. In this review, we discuss the prevalence of FT in patients with leukemia who are eligible for HSCT. We review the impact of FT on financial and clinical outcomes and the role of various interventions that have been studied within this population.

BMC Cancer 2022; 22:1174.

Abstract
BACKGROUND For patients with acute myeloid leukaemia (AML), the only potentially curative treatment is intensive chemotherapy (IC). This is highly toxic, particularly for patients > 60 years, potentially leading to prolonged hospitalisations requiring intensive supportive care, and sometimes treatment-related death. This also results in extensive healthcare costs and negatively impacts quality of life (QoL). Venetoclax with low-dose cytarabine (VEN + LDAC) is a novel, low-intensity treatment for AML patients who cannot receive IC. VEN + LDAC is given as an outpatient and toxicity appears significantly lower than with IC. Analysis of clinical trials performed to date are promising for patients with the genotype NPM1mutFLT3 ITDneg, where remission and survival rates appear comparable to those achieved with IC. METHODS VICTOR is an international, two-arm, open-label, multi-centre, non-inferiority, randomised-controlled phase II trial to assess VEN + LDAC compared to standard of care (IC) as first-line treatment in older patients (initially aged ≥ 60 years) with newly diagnosed AML. The trial will recruit patients with a NPM1mutFLT3 ITDneg genotype; those with a favourable risk in relation to the experimental treatment. University of Birmingham is the UK co-ordinating centre, with national hubs in Aarhus University Hospital, Denmark, and Auckland District Health Board, New Zealand. The primary outcome is molecular event-free survival time where an event is defined as failure to achieve morphological complete response (CR) or CR with incomplete blood count recovery after two cycles of therapy; molecular persistence, progression or relapse requiring treatment change; morphological relapse, or; death. Secondary outcomes include cumulative resource use at 12- and 24-months, and QoL as assessed by EORTCQLQ-C30 and EQ-5D-3L at 3-, 6-, 12-, 18- and 24-months. The trial employs an innovative Bayesian design with target sample size of 156 patients aged > 60 years. DISCUSSION The principle underpinning the VICTOR trial is that the chance of cure for patients in the experimental arm should not be compromised, therefore, an adaptive design with regular checks on accumulating data has been employed, which will allow for a staged expansion of the trial population to include younger patients if, and when, there is sufficient evidence of non-inferiority in older patients.

Abstract
Aim: This retrospective, observational study assessed healthcare resource utilization (HCRU) and costs for newly diagnosed acute myeloid leukemia (AML) patients receiving intensive induction chemotherapy. Materials & methods: Adult AML patients with inpatient hospitalization or hospital-based outpatient visit receiving intensive induction chemotherapy (CPX-351 or 7 + 3 treatments) were identified from the Premier Healthcare Database (US). Results: All 642 patients had inpatient hospitalizations (median number = 2; median length of stay = 16 days); 22.4% had an ICU admission. Median total outpatient hospital cost was US$2904 per patient, inpatient hospital cost was $83,440 per patient, and ICU cost was $16,550 per patient. Discussion: In the US hospital setting, substantial HCRU and costs associated with intensive induction chemotherapy for AML were driven by inpatient hospitalizations.

Abstract
PURPOSE: Patients with hematologic malignancies are extremely vulnerable to financial toxicity (FT) because of the high costs of treatment and health care utilization. This pilot study identified patients at high risk because of FT and attempted to improve clinical outcomes with comprehensive intervention. METHODS: All patients who presented to the Levine Cancer Institute's Leukemia Clinic between May 26, 2019, and March 10, 2020, were screened for inclusion by standardized two question previsit survey. Patients screening positive were enrolled in the comprehensive intervention that used nurse navigators, clinical pharmacists, and community pro bono financial planners. Primary outcomes were defined as improvement in mental and physical quality of life in all patients and improvement in overall survival in the high-risk disease group. RESULTS: One hundred seven patients completed comprehensive intervention. Patients experiencing FT had increased rates of noncompliance including to prescription (16.8%) and over-the-counter medications (15.9%). The intervention resulted in statistically significantly higher quality of life when measured by using Patient-Reported Outcomes Measurement Information System physical (12.5 ± 2.2 v 13.7 ± 1.8) and mental health scores (11.4 ± 2.2 v 12.4 ± 2.2; all P < .001). In patients with high-risk disease (as determined by using disease-specific scoring systems), risk of death in those receiving the intervention was 0.44 times the risk of death in those without the intervention after adjusting for race, and treatment with stem-cell transplant, oral chemotherapy, or immunotherapy (95% CI, 0.21 to 0.94; P = .034). CONCLUSION: Screening and intervention on FT for patients with hematologic malignancies is associated with increased quality of life and survival.

Abstract
BACKGROUND Real-world estimates of relapsed or refractory (R/R) acute myeloid leukemia (AML) chemotherapy episode costs are scarce. We quantified chemotherapy episode-related costs and healthcare resource use (HRU) in R/R AML. RESEARCH DESIGN AND METHODS This real-world, retrospective analysis of United States claims from IQVIA's PharMetrics® Plus database (October 2008-September 2019) identified adults with R/R AML and ≥1 chemotherapy episode. Chemotherapy episode (ie, low- [LIC] or high-intensity [HIC] chemotherapy) costs and HRU were determined using inpatient, outpatient, and pharmacy claims. RESULTS Mean (SD) and median total all-cause healthcare costs per R/R AML chemotherapy episode were $230,799 ($300,770) and $129,117. Mean (SD) and median adjusted direct R/R AML chemotherapy episode costs were $116,384 ($151,425) and $63,298, with increases noted from the first to the second and subsequent episodes and with HIC. Hospitalizations were the major cost driver; 64.1% of patients had ≥1 hospitalization and 36% required an intensive care unit stay. CONCLUSIONS R/R AML chemotherapy episode costs were high, with higher costs reported with HIC and increasing lines of chemotherapy. Hospitalizations were a main cost driver. Novel therapies with comparable or improved effectiveness and decreased need for hospitalizations versus chemotherapy may help alleviate the clinical and economic burden of R/R AML.

Abstract
Objectives This retrospective chart review examined real‐world healthcare resource utilization (HRU) in patients with AML ineligible for intensive therapy who received first‐line systemic therapy or best supportive care (BSC). Methods Data were collected anonymously on patients with AML who initiated first‐line hypomethylating agents (HMA), low‐dose cytarabine (LDAC), other systemic therapy, or BSC. HRU endpoints included hospitalizations, outpatient consultations, transfusions, and supportive care. Results Of 1762 patients included, 46% received HMA, 11% received LDAC, 17% received other systemic therapy, 26% received BSC; median treatment durations were 118, 35, 33, and 57 days, respectively. Most patients were hospitalized, most commonly for treatment administration, transfusion, or infection (HMA 82%, LDAC 93%, other systemic therapy 83%, BSC 83%). A median number of hospitalizations were 2–6 across systemic groups and two for BSC, with median durations of 8–18 days. Transfusion rates and outpatient consultations were highest for HMA (80% and 79%) versus LDAC (57% and 53%), other systemic therapy (57% and 63%), and BSC (71% and 66%). Antivirals/antibiotics and antifungals were used more frequently than growth factors (72–92%, 34–63%, and 7–27%, respectively). Conclusion Patients with AML ineligible for intensive therapy have high HRU; novel therapies are needed to alleviate this burden.

Abstract
Simple Summary Studies addressing the economic costs and burden of secondary acute myeloid leukemia (sAML) are scarce in the literature. We analyzed this topic in a real-life population of sAML patients between 60–75 years receiving intensive chemotherapy induction. In elderly patients with sAML and intensive regimens, it entails an increase in costs and a longer hospital stay. In these specific patients, almost a third of the time is spent hospitalized after the diagnosis of sAML. There are no studies with this type of population and diagnosis, which gives added value to the results obtained. Pharmacoeconomic studies in patients with AML are being carried out due to the need to evaluate the cost-effectiveness of new oral drugs, therapeutic schemes with higher costs than previous treatments. Abstract Background: Information regarding the impact on healthcare systems of secondary acute myeloid leukemia (sAML) is scarce. Methods: A retrospective review of medical charts identified patients aged 60–75 years with sAML between 2010 and 2019. Patient information was collected from diagnosis to death or last follow-up. Outpatient resource use, reimbursement, frequency and duration of hospitalization, and transfusion burden were assessed. Forty-six patients with a median age of 64 years were included. Anthracycline plus cytarabine regimens were the most common induction treatment (39 patients, 85%). The ratio of the total days hospitalized between the total follow-up was 29%, with a sum of 204 hospitalizations (average four/patient; average duration 21 days). The total average reimbursement was EUR 90,008 per patient, with the majority (EUR 77,827) related to hospital admissions (EUR 17,403/hospitalization). Most hospitalizations (163, mean 22 days) occurred in the period before the first allogeneic hematopoietic stem cell transplant (alloHSCT), costing EUR 59,698 per patient and EUR 15,857 per hospitalization. The period after alloHSCT (in only 10 patients) had 41 hospitalizations (mean 21 days), and a mean reimbursement cost of EUR 99,542 per patient and EUR 24,278 per hospitalization. In conclusion, there is a high consumption of economic and healthcare resources in elderly patients with sAML receiving active treatments in Spain.

Abstract
BACKGROUNDS An increasing incidence of Acute Myeloid Leukaemia (AML) has been reported in several Western countries. However, the epidemiology of AML in Asia is very limited. According to the National Comprehensive Cancer Network (NCCN) guideline of AML, a range of conventional therapy options is available to AML patients. Nevertheless, different treatment strategies may result in diverse healthcare utilization and costs. Understanding the treatment patterns, healthcare utilization and costs of AML would thus be essential for clinicians and policymakers to optimize the treatment strategies of AML. OBJECTIVES The objective of this study was to investigate the incidence, treatment patterns, healthcare utilization and costs of AML in Taiwan using a nationwide population database. METHODS We retrospectively identified AML patients diagnosed from 2006 to 2015 from the Taiwan Cancer Registry Database (TCRD) and estimated the epidemiology of AML in Taiwan. The TCRD was linked to National Health Insurance Research Database (NHIRD) to collect the treatment patterns and health care utilization. Patients diagnosed with AML from 2011 to 2015 were further identified to analyze treatment patterns, healthcare utilization and costs. RESULTS The crude annual incidence of AML increased from 2.78 to 3.21 cases per 100,000 individuals from 2006 to 2015. However, the age-standardized rate (ASRs) of AML slightly declined from 2.47 to 2.41 cases per 100,000 individuals in the same period. Among 2,179 AML patients who received induction therapy (median age: 56 years), most of them (n = 1744; 80.04%) received standard-dose cytarabine (SDAC) regimen. The remaining 162 patients received high dose cytarabine (HDAC) and 273 patients received non-standard dose cytarabine (N-SDAC) regimen as the induction therapy. The median medical costs in our study for patients treated with chemotherapy alone was $42,271 for HDAC, $36,199 for SDAC and $36,250 for N-SDAC. For those who received hematopoietic stem cell transplantation (HSCT) after induction therapy, their median medical costs were $78,876 for HDAC, $78,593 for SDAC and $79,776 for N-SDAC. CONCLUSIONS This study is the first population-based study conducted in Asia to provide updated and comprehensive information on epidemiology, treatment patterns and healthcare resource utilization and costs of AML.

Abstract
Purpose CPX-351 is dual-drug liposomal encapsulation of daunorubicin and cytarabine at a fixed synergistic 1:5 molar ratio. This study determined current real-world use of CPX-351 versus conventional 7+3 (cytarabine+daunorubicin) therapy and evaluated hospital length of stay (LOS) and supportive care utilization in t-AML and AML-MRC. Patients and Methods This retrospective, observational study utilized the Premier Healthcare Database and included patients who were aged ≥18 years with t-AML or AML-MRC and treated with CPX-351 or 7+3 between August 1, 2017 and February 28, 2019. All patients treated with 7+3 were required to be eligible for CPX-351 based on its FDA-approved indication. Outcome variables were annualized and adjusted for patient, hospital, and clinical confounding factors. The primary outcome was inpatient LOS. Secondary outcomes included use of blood products and use of anti-infectives. Results The study included 195 qualifying patients treated with CPX-351 and 160 patients treated with 7+3 who were eligible for CPX-351. Approximately one-third of the patients treated with CPX-351 were administered therapy in a hospital-based outpatient setting, and all patients treated with 7+3 received it in the inpatient setting. The regression-adjusted annualized inpatient LOS was shorter with CPX-351 than 7+3 (mean of 183.7 vs 197.1 days, p<0.001). The difference in mean-adjusted LOS was most pronounced for t-AML, with a mean-adjusted LOS of 168.9 versus 192.5 days for CPX-351 versus 7+3, respectively (nominal p<0.001). Supportive care utilization, including the number of administrations of red blood cells, the number of administrations of platelets, and the number of days on anti-infectives, was similar between treatment groups. Conclusion CPX-351 was associated with a shorter inpatient LOS than 7+3. Supportive care use, including blood products and anti-infectives, was similar for CPX-351 and 7+3. These findings suggest CPX-351 conveys resource advantages over 7+3 in patients with newly diagnosed t-AML and AML-MRC.

Abstract
BACKGROUND AND AIMS Acute myeloid leukemia (AML) prognosis is poor, with sustained remission occurring in <35% of young adults and <15% of older adults. This descriptive study examined the potential benefit of prolonged remission on the economic burden of AML. METHODS Using the IBM MarketScan Commercial and Medicare Supplemental databases, we identified newly diagnosed patients with AML without hematopoietic stem cell transplantation from January 1, 2012 to December 31, 2018; AML diagnosis was the index date. Patients had 6 months of pre-index eligibility and were followed until the end of continuous eligibility, study data, or death. Active treatment and supportive care cohorts were defined; duration-of-remission subgroups (0 to <3, 3 to <6, 6 to <12, and ≥12 months) were established among active treatment patients with remission. Healthcare service utilization and costs were reported over follow-up and mutually exclusive treatment, remission, and post-relapse periods. RESULTS This study included 1,558 active treatment and 1,127 supportive care patients who were followed for a median of 232 and 62 days, respectively. Over follow-up, active treatment and supportive care patients incurred mean ± standard deviation all-cause healthcare costs of $55,723 ± $61,994 and $68,596 ± $100,375 per-patient-per-month (PPPM), respectively. Decreasing PPPM costs were observed with increased remission duration (0 to <3 months: $71,823 ± $62,635; 3 to <6 months: $54,262 ± $44,734; 6 to <12 months: $35,287 ± $23,699; and ≥12 months: $15,615 ± $10,560). Although median follow-up varied by up to 5-fold, total costs were largely similar across duration-of-remission subgroups (0 to <3 months: $438,569 ± $332,675; 3 to <6 months: $590,411 ± $598,245; 6 to <12 months: $482,902 ± $369,115; and ≥12 months: $448,867 ± $316,133). CONCLUSIONS The economic burden of AML is substantial, even among untreated patients. Further, among patients with remission, longer durations in remission are associated with reduced PPPM healthcare costs, suggesting that remission-prolonging treatments could help mitigate healthcare costs.

Abstract
The present study assessed changes in patient management, economic burden, and overall survival (OS) in a contemporary cohort of 2775 US Medicare Advantage beneficiaries aged ≥66 years newly diagnosed with acute myeloid leukemia (AML) between 01 January 2015 and 30 June 2020. Use of venetoclax-based therapy increased and replaced hypomethylating agent (HMA) monotherapy as the most common first-line treatment choice in 2019-2020. In newly diagnosed AML patients aged ≥75 and 66-74 years, mean per-patient 1-year healthcare expenditures were $81,818 and $156,033 (2020 USD) and median OS was 2.3 and 8.5 months, respectively. In addition, 40% of Medicare Advantage patients with newly diagnosed AML continue to receive supportive care alone. These findings indicate that at the population level clinical outcomes remain poor for older adults with AML, pointing to a continuing unmet medical need.

Abstract
To describe patient characteristics, treatment patterns, and survival among elderly patients (≥66 years) newly diagnosed with acute myeloid leukemia (AML) meeting ≥1 ineligibility criteria for high-intensity chemotherapy (HIC; i.e. age >75 years, cardiac disease/prior anthracycline therapy, or secondary AML), we analyzed 2007-2017 100% Medicare hematologic cancer data. Patients were stratified based on whether they received HIC or low-intensity chemotherapy (LIC) or best supportive care (BSC) within 60 days after AML diagnosis. Of 4,152 patients, 43.2% received chemotherapy, 33.8% BSC, and 23.1% no therapy. Among chemotherapy-treated patients, HIC was more common than LIC (58.8 vs 41.2%), despite targeting patients meeting ≥1 ineligibility criteria for HIC. Poor overall survival was observed for patients receiving chemotherapy and BSC (median overall survival [interquartile range]: HIC, 1.9 [0.8, 6.6] months; LIC, 3.8 [1.4, 9.3] months; BSC, 1.0 [0.4, 2.5] months). Results highlight the need for additional effective and tolerable treatments for this population.

Abstract
Acute myeloid leukemia (AML) is associated with a high economic and clinical burden. Recently novel therapies have been added to standard treatment regimens. Here, we evaluated the economic impact of AML up until the introduction of these novel therapies. Individual data on 2954 adult patients diagnosed from 2007 to 2015 from five Swedish national population‐based registers were used, enabling analyses from diagnosis to either death or 5‐year follow‐up for survival, inpatient and outpatient costs, costs of prescribed drugs, sick leave, and early retirement. Costs per patient were stratified by age group, treatment options, and FLT3‐ITD status. The expected 5‐year costs per patient differed substantially between age groups. Patients aged 18–59 years had an expected mean cost per patient of €170,748, while age groups 60–69 years, 70–79 years, and >80 years incurred an expected mean cost of €92,252, €48,344, and €24,118, respectively, over 5 years. Patients <60 years undergoing stem cell transplantation had the highest costs (€228,525 over 5 years). About 60% of costs for these patients were from hospitalizations and 20% from sick leave and early retirement; cost per day was highest from the first admission to complete remission. This study provides a baseline for socioeconomic evaluations of novel therapies in AML in Sweden.

Abstract
Acute myeloid leukemia (AML) is conventionally treated with chemotherapy in eligible patients. Potentially curative regimens are associated with significant toxicity, and the major cost drivers in AML historically have been hospitalization and hematopoietic stem cell transplantation. The past several years have seen a dramatic increase in the number of treatment options, including oral therapies and drugs targeted to biological pathways implicated in AML. Major current and future drivers of cost in AML include hospitalization and medical costs, stem cell transplantation for eligible patients, and medication costs. It is likely that hospitalization and medical costs will decline as more AML treatment moves to the outpatient setting. Stem cell transplantation costs may increase, if more patients are eligible for improved procedures, although the overall cost of transplantation could decrease if new procedures reduce the need for hospitalization. Medication costs are likely to increase, with various branded drugs available and in development. From a broader perspective, another driver of cost is the proportion of patients with AML who can undergo treatment. Patients who may previously have been unable to tolerate chemotherapy are more likely to be treated with the range of less intensive, more tolerable options now available. The effectiveness of newer AML treatment options also suggests that, overall, there may be more patients staying alive and on treatment longer than in the past. While certain advances, such as increased use of oral and outpatient therapies, could potentially reduce costs, the overall economic impact of AML is likely to increase as more patients are eligible for novel therapies across several phases from induction to maintenance to relapsed/refractory disease. While these novel therapies have the potential to deliver value in the form of improved efficacy, safety, and convenience, payers will need to determine how to cover a longer, more complex AML treatment pathway.

Abstract
Aim: Assess treatment patterns and healthcare resource utilization (HRU) in patients with treatment-naive (TN) or relapsed/refractory (R/R) acute myeloid leukemia (AML) in Europe. Patients & methods: Cross-sectional, retrospective, web-based survey of AML-treating healthcare professionals (HCPs) in 12 European countries. Results: 320 HCPs provided information on 1280 TN or R/R patients. Patients ineligible versus eligible for intensive induction therapy required more general practitioner visits (4.1 vs 2.4), more uses of healthcare-related transport (6.9 vs 4.5), but less hospitalization (11.4 vs 27.5 days). Differences were observed in HRU and treatment patterns across countries. Conclusions: This analysis of 'real-world' patients with TN or R/R AML in Europe demonstrates substantial healthcare use, including higher use of resources in patients ineligible for intensive induction therapy.

Abstract
BACKGROUND Acute myeloid leukemia (AML) is the most common acute leukemia in adults, and chemotherapy remains the most commonly used treatment approach for this group of hematological disorders. Drug resistance is one of the predictors of unfavorable prognosis for leukemia patients. AIM The purpose of this study was to perform a retrospective analysis of the survival rate in AML patients according to age, tumor status, and chemotherapy regimen received and to analyze the therapy response of AML patients depending on the treatment received, initial responsiveness of tumor cells to chemotherapeutic drugs measured in vitro at diagnosis and expression of immunological markers. METHODS The survival of AML patients (n = 127) was analyzed using the Kaplan-Meier method. Drug sensitivity of tumor cells of AML patients (n = 37) and the expression of immunological markers were evaluated by the WST test and flow cytometry, respectively. Correlation analysis was performed using Spearman's rank order correlation coefficient. RESULTS We found the treatment regimen to be the defining factor in the patient survival rate. In addition, the initial responsiveness of tumor cells to chemotherapeutic drugs measured in vitro at diagnosis correlated with the therapy response of AML: patients with high tumor cell sensitivity to particular cytotoxic drugs demonstrated a good response to treatment including these drugs, and patients with initial resistance of tumor cells to a particular chemotherapeutic agents and received it according to the clinical protocols demonstrated a poor response to antitumor therapy. Correlations of drug resistance in leukemic cells with the expression of immature and aberrant immunophenotype markers as established unfavorable prognostic factors confirm our assumption. CONCLUSION The evaluation of the responsiveness of tumor cells to chemotherapy in vitro at diagnosis can be a useful tool for predicting the response of leukemia patients to planned chemotherapy.

Abstract
Aims: Treatment of acute myeloid leukemia (AML) requires significant healthcare resource utilization (HRU), including lengthy hospitalizations. In a phase 3 study (NCT01696084), CPX-351 (Vyxeos) showed significant benefits to overall survival and complete remission versus conventional 7 + 3 cytarabine/daunorubicin. This analysis evaluated HRU in patients aged 60-75 years with newly diagnosed high-risk/secondary AML treated with CPX-351 versus 7 + 3 in the phase 3 study.Materials and methods: Patients were randomized to receive up to two induction cycles with CPX-351 or 7 + 3. Responders could receive up to two cycles of consolidation. To normalize HRU to length of treatment, patients were assessed on a per patient-year (PPY) basis. HRU analyses included hospital and intensive care unit (ICU) stays, anti-infective use, transfusions, and white blood cell colony-stimulating factor (CSF).Results: The median (range) total duration of hospitalization was 39 (3-110) days with CPX-351 (n = 153) and 32 (2-83) days with 7 + 3 (n = 151); the estimated durations of hospitalization PPY were 198.4 and 240.5 days, respectively. The median (range) total duration of ICU stays was 0 (0-45) days with CPX-351 and 0 (0-17) days with 7 + 3; the estimated durations of ICU stays PPY were 6.7 and 10.5 days, respectively. When comparing supportive care use during CPX-351 and 7 + 3 treatment, the estimated number PPY of bags of platelets used (24.6 vs 26.9, respectively), bags of packed red blood cells used (13.0 vs 13.9), days of anti-infectives (162.0 vs 159.2), and days of CSF (4.0 vs 2.4) were not notably different.Limitations: This clinical study analysis may not represent real-world HRU patterns or be generalizable to a broader AML population.Conclusions: These PPY data, showing shorter durations of hospitalization and similar use of supportive care with CPX-351 versus 7 + 3, suggest CPX-351 is not associated with increased HRU in older patients with newly diagnosed high-risk/secondary AML.

Abstract
Background: The attempt to manage patients with acute myeloid leukemia as outpatients has become increasingly common due to high hospitalization costs, low availability for beds and patient preference. Publications on the subject are scarce, especially in low-income regions and the safety in this population remains to be determined. The present study aims to assess the safety of consolidation with high-dose cytarabine in the outpatient setting. Materials and Methods: We retrospectively analyzed 39 patients who underwent consolidation with high-dose cytarabine, between 2009 and 2018, at Ophir Loyola Hospital, in Belém, Brazil. Patients treated after 2015 were given high-dose cytarabine as outpatients due to the decision of medical staff. Results: Twenty-seven patients received 76 cycles of cytarabine as outpatients; males were 48.14% of the total population, with a median age of approximately 45 years. The occurrence of delay between cycles was significantly lower among outpatients (48.14% vs. 83.33%, p = 0.04). There was no difference in relapse rates, transfusion requirements and non-relapse mortality between both groups. Hospitalization was required in 40.74% of patients during outpatient cycles and 18.51% of blood cultures were positive for pathogens. Non-relapse mortality was significantly higher among patients above 50 years old and treated on an outpatient basis (44.4% vs. 5.60%, p = 0.03). Conclusion: High-dose cytarabine administration on an outpatient basis appears to be safe and effective in a low-income population at the Brazilian Amazon region, but toxicity seems to be increased for patients older than 50 years.

Abstract
This retrospective study estimated healthcare resource use (HRU), symptoms and toxicities (SxTox), and costs in relapsed/refractory (R/R) patients with acute myeloid leukemia (AML), stratified by hematopoietic stem cell transplantation (HSCT) status. Claims data were used to identify adult patients with AML diagnoses from 1 January 2008 to 31 March 2016 in the USA. Patients were considered R/R if they had an AML relapse ICD-9 code (205.02) or a line of therapy consistent with R/R disease. The final R/R sample (N = 707) included 476 patients with and 231 patients without HSCT. The mean total episode cost (from relapse date to death or end of study period) for all patients was $439,104 (with HSCT $524,595 and without HSCT $263,310). Inpatient visits accounted for the greatest cost component (mean $308,978) followed by intensive care unit stays (mean $221,537), non-clinician (e.g., lab tests) visits (mean $30,909), and outpatient pharmacy utilization (mean $24,640). Patients with HSCT appeared to have longer episodes of care compared with patients without HSCT (16.8 vs 11.1 months), perhaps reflecting longer survival for HSCT patients. Mean number of visits within each category and their associated costs appeared to be higher in patients with HSCT compared with patients without HSCT. Patients with HSCT appeared to experience more SxTox compared with patients without HSCT across all categories. Results of the current study suggest that there is a substantial HRU and cost burden on R/R AML patients in the USA receiving active treatments. More effective therapies with improved tolerability would meet this tremendous unmet need in the R/R AML population. Funding: Astellas Pharma, Inc.

Abstract
Aim: To assess multi-gene assay (MGA) effects on chemotherapy use, toxicities, recurrences, and costs in estrogen receptor-positive early breast cancer. Methods: Meta-analysis performed using data from public databases. Results: Studies included 12,202 women. Relative to no testing, chemotherapy use was higher with 12-gene and 70-gene and lower with PAM50 (commercial) and 21-gene MGAs. Overall, 1643 distant recurrences occurred with no testing, declining by 231 (21-gene), 121 (70-gene), 54 (12-gene) and 94 (PAM50); only the 21-gene assay resulted in no risk of increasing the number of distant recurrences. Relative to ‘no testing’, total cost of care declined only with 21-gene MGA. Conclusion: MGAs differ in chemotherapy use and related outcomes for women with estrogen receptor-positive early breast cancer.

Abstract
OBJECTIVES To assess real-world treatment patterns and healthcare resource utilization (HRU) among patients with FLT3-mutated (FLT3mut ) and FLT3-wild-type (FLT3wt ) acute myeloid leukemia (AML). METHODS Data were abstracted from medical charts of patients with AML from 10 countries. Patients were grouped based on their FLT3 mutation status, age (18-64 or ≥65), and whether they were newly diagnosed (ND) or relapsed/refractory (R/R). RESULTS Charts of 1027 AML patients were included (183 FLT3mut 18-64 ND; 136 FLT3mut ≥65 ND; 181 FLT3mut R/R; 186 FLT3wt 18-64 ND; 159 FLT3wt ≥65 ND; 182 FLT3wt R/R). Substantial heterogeneity was observed in treatment patterns for AML. Among ND patients 18-64, the most common initial treatment was standard-to-intermediate dose cytarabine-based therapies (43.2% for FLT3mut and 55.9% for FLT3wt ); among ND patients ≥65, the most common initial treatment was hypomethylating agent-based therapies (36.0% and 47.2%). Among R/R patients, the most common initial treatment after R/R was best supportive care only (39.8% and 24.7%). HRU was substantial across cohorts during both event-free and post-event periods. CONCLUSIONS Treatment patterns of AML were heterogeneous and FLT3mut AML was treated more aggressively than FLT3wt disease. HRU was substantial for all cohorts, particularly after relapse or treatment failure.

Abstract
AIM Acute myeloid leukemia (AML) is associated with high disease burden. This analysis estimated HRU and costs among newly diagnosed AML patients in a US commercially insured population. MATERIALS AND METHODS This was a retrospective observational study using the IMS Health PharMetrics Plus and Hospital Charge Detail Master databases. Patients included adults who were newly diagnosed with AML between January 2007 and June 2016 ("study period"). Patients with <12 months of continuous enrollment prior to the index date were excluded, as were those whose first diagnosis was AML in remission/relapse, those diagnosed with acute promyelocytic leukemia, those on Medicare supplemental insurance, or those with a diagnosis of AML in remission/relapse without evidence of treatment during the study period. Patients were stratified by receipt of AML treatment (chemotherapy/hematopoietic cell transplantation [HCT]), and their follow-up was partitioned into initial, remission, and relapsed health states. Mean HRU and costs were tallied by treatment and, for treated patients, by health state and time since entry into health state (≤6 vs >6 months). RESULTS A total of 9,455 patients met study criteria, including 6,415 (68%) treated and 3,040 (32%) untreated patients, with mean follow-up of 18.3 and 16.4 months, respectively. Mean age was 55 years in treated patients and 60 years in untreated patients. Mean total costs per patient were $386,077 in treated patients and $79,382 in untreated patients. For treated patients, 60% of total costs ($231,867 per patient) were incurred during the initial health state, representing time without remission/relapse. Mean monthly total healthcare costs were $21,055 and $4,854 among treated and untreated patients, respectively. LIMITATIONS AND CONCLUSIONS HRU and costs of managing AML patients are substantial. In treated patients, the majority of costs were incurred during the initial treatment period, without claims indicating remission/relapse.

Abstract
OBJECTIVE To describe the setting, duration, and costs of induction and consolidation chemotherapy for adults with newly-diagnosed acute myeloid leukemia (AML), who are candidates for standard induction chemotherapy, in the US. METHODS Adults newly-diagnosed with AML who received standard induction chemotherapy in an inpatient setting were identified from the Truven Health Analytics MarketScan (2006-2015) and SEER-Medicare (2007-2011) databases. Patients were observed from induction therapy start to the first of hematopoietic stem cell transplant, 180 days after induction discharge, health plan enrollment/data availability end, or death. Induction and consolidation chemotherapy were identified using Diagnosis-Related Group codes (chemotherapy with acute leukemia) or procedure codes for AML chemotherapy administration. AML treatment episode setting (inpatient or outpatient), duration, and costs (2015 USD, payers' perspective) were described for commercially insured patients and Medicare beneficiaries. RESULTS In total, 459 commercially insured patients and 563 Medicare beneficiaries (mean age = 54 and 66 years; 53% and 54% male; respectively) were identified. For induction therapy, mean costs were $145,189 for commercially insured patients and $85,734 for Medicare beneficiaries, and median inpatient duration was 31 days (both). Following induction, 64% of commercially insured patients and 53% of Medicare beneficiaries had ≥1 consolidation cycle; 75% and 65% of consolidation cycles were in an inpatient setting, respectively. For consolidation cycles, in the inpatient setting, mean costs were $28,137 for commercially insured patients and $28,843 for Medicare beneficiaries, median cycle duration was 6 days (both); in the outpatient setting, mean costs were $11,271 for commercially insured patients and $5,803 Medicare beneficiaries, median duration was 5 days (both). LIMITATIONS Granular information on chemotherapy type administered was unavailable. CONCLUSIONS This is the first exploratory study providing a complete picture of recent AML treatment patterns and management costs among commercially insured patients and Medicare beneficiaries. There is substantial heterogeneity in the management and costs of AML.

Abstract
PURPOSE Acute myeloid leukemia (AML) disproportionately affects older adults; the prognosis in this subpopulation is generally poor, with variable use of inpatient chemotherapy. This study characterizes treatment patterns, hospitalizations, and outcomes among older patients with AML. METHODS Using the Centers for Medicare & Medicaid Services' 2010-2012 100% Limited Data Set (LDS), data from all hospital claims from fee-for-service Medicare beneficiaries between 60 and 75 years of age with newly diagnosed AML and ≥1 hospitalization were analyzed. FINDINGS Among 3700 identified patients with AML, 1979 (53.5%) received chemotherapy. Hospitalization rates were highest initially and then declined over time, irrespective of chemotherapy use. The mean length of initial hospital stay was longer in patients receiving chemotherapy. Intensive care unit admissions occurred in 33% of initial hospitalizations. Factors associated with receiving chemotherapy included younger age, fewer comorbidities, and the absence of prior hematologic disorders. Chemotherapy was associated with significantly increased survival compared with no chemotherapy (P < 0.0001). IMPLICATIONS AML in older patients is associated with frequent hospitalizations and intensive care unit admissions. New treatment options with more favorable risk-to-benefit profiles are needed in this population.

Abstract
The standard therapy of AML for many years has been chemotherapy with or without stem transplantation. However, there has not been any tangible improvement in this treatment beyond induction through chemotherapy and consolidation with allogeneic stem cell transplantation or chemotherapy. Residual AML cells which later cause relapse mostly persist even after rigorous standard therapy. It is imperative therefore to find an alternative therapy that can take care of the residual AML cells. With a better understanding of how the immune system works to destroy tumor cells and inhibit their growth, another therapeutic option immunotherapy has emerged to address the difficulties associated with the standard therapy. Identification of leukemia-associated antigens (LAA) and the fact that T and NK cells can be activated to exert cytotoxicity on AML cells have further introduced diverse immunotherapeutic development strategies. This review discusses the merits of current immunotherapeutic strategies such as the use of antibodies, adoptive T cells and alloreactive NK cell, and vaccination as against the standard therapy of AML.
