Abstract
BACKGROUND Oncology settings increasingly use patient experience data to evaluate clinical performance. Given that older patients with hematologic malignancies are a high-risk population, this study examined factors associated with patient-reported health care experiences during the first year of their cancer diagnosis. METHODS Cross-sectional study using the 2000-2015 SEER-CAHPS® data to examine patient experiences of Medicare enrollees with a primary diagnosis of leukemia or lymphoma. The primary outcomes were three CAHPS assessments: overall care, personal doctor, and health plan overall. We estimated case-mix adjusted and fully adjusted associations between factors (i.e., clinical and sociodemographic) and the CAHPS outcomes using bivariate statistical tests and multiple linear regression. RESULTS The final sample included 1,151 patients, with 431 diagnosed with leukemia and 720 diagnosed with lymphoma (median time from diagnosis to survey 6 months). Patients who completed the survey further apart from the diagnosis date reported significantly higher adjusted ratings of care overall (β .39, p = .008) than those closer to diagnosis. American Indian/Alaska Native, Asian, and Pacific Islander patients had lower adjusted ratings of care overall (β - .73, p = .003) than Non-Hispanic white patients. Multimorbidity was significantly associated with higher adjusted personal doctor ratings (β .26, p = .003). CONCLUSIONS Unfavorable patient experiences among older adults diagnosed with hematologic malignancies warrant targeted efforts to measure and improve care quality. Future measurement of experiences of cancer care soon after diagnosis, coupled with careful sampling of high-priority populations, will inform oncology leaders and clinicians on strategies to improve care for high-risk, high-cost populations.

Abstract
BACKGROUND Acute myeloid leukaemia (AML) is the most common acute leukaemia affecting adults. Most patients diagnosed with AML are at advanced age and present with co-morbidities, so that intensive therapy such as stem cell transplantation (SCT) is impossible to provide or is accompanied by high risks for serious adverse events and treatment-related mortality. Especially for these patients, it is necessary to find out whether all-trans retinoic acid (ATRA), an intermediate of vitamin A inducing terminal differentiation of leukaemic cell lines, added to chemotherapy confers increased benefit or harm when compared with the same chemotherapy alone. OBJECTIVES This review aims to determine benefits and harms of ATRA in addition to chemotherapy compared to chemotherapy alone for adults with AML (not those with acute promyelocytic leukaemia (non-APL)). SEARCH METHODS We searched the Central Register of Controlled Trials (CENTRAL), MEDLINE, study registries and relevant conference proceedings up to July 2018 for randomised controlled trials (RCTs). We also contacted experts for unpublished data. SELECTION CRITERIA We included RCTs comparing chemotherapy alone with chemotherapy plus ATRA in patients with all stages of AML. We excluded trials if less than 80% of participants were adults or participants with AML, and if no subgroup data were available. Patients with myelodysplastic syndrome (MDS) were included, if they had a refractory anaemia and more than 20% of blasts. DATA COLLECTION AND ANALYSIS Two review authors independently extracted data and assessed the quality of trials. We contacted study authors to obtain missing information. We used hazard ratios (HR) for overall survival (OS) and disease-free survival (DFS; instead of the pre-planned event-free survival, as this outcome was not reported), and we calculated risk ratios (RR) for the other outcomes quality of life, on-study mortality and adverse events. We presented all measures with 95% confidence intervals (CIs). We assessed the certainty of evidence using GRADE methods. MAIN RESULTS Our search resulted in 2192 potentially relevant references, of which we included eight trials with 28 publications assessing 3998 patients. Overall, we judged the potential risk of bias of the eight included trials as moderate. Two of eight trials were published as abstracts only. All the included trials used different chemotherapy schedules and one trial only evaluated the effect of the hypomethylating agent decitabine, a drug know to affect epigenetics, in combination with ATRA.The addition of ATRA to chemotherapy resulted in probably little or no difference in OS compared to chemotherapy only (2985 participants; HR 0.94 (95% confidence interval (CI) 0.87 to 1.02); moderate-certainty evidence). Based on a mortality rate at 24 months of 70% with chemotherapy alone, the mortality rate with chemotherapy plus ATRA was 68% (95% CI 65% to 71%).For DFS, complete response rate (CRR) and on-study mortality there was probably little or no difference between treatment groups (DFS: 1258 participants, HR 0.99, 95% CI 0.87 to 1.12; CRR: 3081 participants, RR 1.02, 95% CI 0.96 to 1.09; on-study mortality: 2839 participants, RR 1.02, 95% CI 0.81 to 1.30, all moderate-certainty evidence).Three trials with 1428 participants reported the adverse events 'infection' and 'cardiac toxicity': There was probably no, or little difference in terms of infection rate between participants receiving ATRA or not (RR 1.05, 95% CI 0.96 to 1.15; moderate-certainty evidence). We are uncertain whether ATRA decreases cardiac toxicity (RR 0.46, 95% CI 0.24 to 0.90; P = 0.02, very low certainty-evidence, however, cardiac toxicity was low).Rates and severity of diarrhoea and nausea/vomiting were assessed in two trials with 337 patients and we are uncertain whether there is a difference between treatment arms (diarrhoea: RR 2.19, 95% CI 1.07 to 4.47; nausea/vomiting: RR 1.46, 95% CI 0.75 to 2.85; both very low-certainty evidence).Quality of life was not reported by any of the included trials. AUTHORS' CONCLUSIONS We found no evidence for a difference between participants receiving ATRA in addition to chemotherapy or chemotherapy only for the outcome OS. Regarding DFS, CRR and on-study mortality, there is probably no evidence for a difference between treatment groups. Currently, it seems the risk of adverse events are comparable to chemotherapy only.As quality of life has not been evaluated in any of the included trials, further research is needed to clarify the effect of ATRA on quality of life.

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.

One day at a time: improving the patient experience during and after intensive chemotherapy for younger and older AML patients. Leuk Res 2014; 39:192-7.

Abstract
Few studies have focused on survivorship issues in AML patients that have successfully completed treatment, and no study examined age-related differences in survivorship. Therefore, our purpose was to explore the survivorship issues encountered by AML survivors, and explore if these survivorship issues are different for younger and older survivors. Lastly, we explored advice for future patients provided by younger and older AML survivors on how to survive the period of intensive chemotherapy (IC). We conducted a prospective qualitative study with 26 participants (14 younger (age 18-59), 12 older (age 60 or older)) who underwent IC. Data were analyzed using Grounded Theory. Both younger and older survivors reported persistent health issues and functional limitations; however, older participants were more satisfied with their post-treatment function and quality of life. Face-to-face communication, phase-specific information, step-by-step education, and home nursing care were important factors to cope with treatment. Provision of written educational material was highlighted by younger participants. Frequent travel to hospital and long waiting times were identified as undesirable. In conclusion, although we observed that many survivorship issues during and shortly after a diagnosis are similar among younger and older survivors, some issues differ by age, pointing out the need for customized approaches.

Abstract
AbstractRepair of damage to DNA resulting from chemotherapy may influence drug toxicity and survival in response to treatment. We evaluated the role of polymorphisms in DNA repair genes APE1, XRCC1, ERCC1, XPD, and XRCC3 in predicting therapeutic outcomes of older adults with acute myeloid leukemia (AML) from 2 Southwest Oncology Group (SWOG) clinical trials. All patients received standard chemotherapy induction regimens. Using logistic and proportional hazards regression models, relationships between genotypes, haplotypes, and toxicities, response to induction therapy, and overall survival were evaluated. Patients with XPD Gln751C/Asp312G (‘D’) haplotype were more likely to have complete response (OR = 3.06; 95% CI, 1.44-6.70) and less likely to have resistant disease (OR = 0.32; 95%CI, 0.14-0.72) than patients with other haplotypes. ERCC1 polymorphisms were significantly associated with lung (P = .037) and metabolic (P = .041) toxicities, and patients with the XRCC3 241Met variant had reduced risk of liver toxicity (OR = 0.32; 95%CI, 0.11-0.95). Significant associations with other toxicities were also found for variant XPD genotypes/haplotypes. These data from clinical trials of older patients treated for AML indicate that variants in DNA repair pathways may have an impact on both outcomes of patients and toxicities associated with treatments. With validation of results in larger samples, these findings could lead to optimizing individual chemotherapy options.

Abstract
BACKGROUND Conflicting results have been reported about the prognostic relevance of antecedent myelodysplastic syndrome (MDS) in acute myeloid leukemia (AML) of older adults. PATIENTS AND METHODS Data from 87 intensively treated AML patients (median age 69 years) were analyzed, with the aim of comparing therapeutic results and toxicity between de novo and AML secondary to a previous MDS (s-AML). Rate of CD34+ cells mobilization and feasibility of autologous stem cell transplantation (ASCT) were also compared. RESULTS Complete remission rate, death in induction and primary resistance were not statistically different between the two groups. Median time for neutrophil recovery was similar, while s-AML patients required a longer time for platelet recovery (P = 0.04). There was no difference as to eligibility for consolidation as well as for mobilization and feasibility of ASCT. S-AML had negligible impact on overall survival (OS) and disease-free survival (DFS). In the multivariate analysis the only parameter significantly related to either OS or DFS duration was adverse karyotype (P = 0.02 and 0.04, respectively). CONCLUSIONS A diagnosis of s-AML does not represent a clinically relevant prognostic factor in elderly AML patients treated with aggressive therapy. Furthermore, s-AML patients can be mobilized and autografted with comparable results as opposed to de novo cases.

Abstract
Acute leukemia is common in the elderly and, due to the aging population and poorer prognosis, represents a major challenge. Elderly acute leukemia patients have been arbitrarily defined as >or=55 to 65 years of age and are underrepresented in clinical trials. There are physiologic differences between elderly and non-elderly patients. A comprehensive understanding of these differences allows the development of a systematic approach to assessing the risks for treatment-related complications. Use of a comprehensive geriatric assessment (CGA), initially developed and validated in the general geriatric population, may allow more accurate assessment of the likelihood of chemotherapy-induced complications and allow for proactive risk minimization. Once complications to therapy develop, aggressive treatment is essential. Treatment related to common complications that arise from therapy will be reviewed. Further research directed at this population is required.

Abstract
We assessed remission rates and toxicity in 24 consecutive elderly (age>or=60) patients with untreated Acute myeloid leukemia (AML) who received the anthracycline-free combination of fludarabine, cytosine arabinoside and G-CSF (FLAG) as initial induction chemotherapy at our center. CR was achieved following one cycle of FLAG in 14 patients (58%). Another four patients cleared blasts from their bone marrow by day 30 without complete platelet recovery. Three patients died from infections prior to neutrophil recovery (12%). No other grade 3/4 toxicities and no clinically significant mucositis were seen. No significant association was found between age, WBC and cytogenetic risk group with likelihood of achieving CR. Fifteen patients proceeded to consolidation therapy and seven patients received a stem cell transplant (six autologous, one allogeneic). Primary induction with FLAG in elderly AML patients achieves a high remission rate without prohibitive mucosal or cardiac toxicity and may thus be considered as an alternative to standard anthracycline-based regimens in this setting.

Abstract
The optimal postremission treatment for elderly patients with acute myelogenous leukemia (AML) is presently unknown, but recent studies report the feasibility of autologous stem cell transplantation in this population. To better understand the long-term outcome of autologous transplantation in AML patients > or =60 years of age, we evaluated high-dose chemoradiotherapy preparative conditioning followed by transplantation of peripheral blood progenitor cells procured after a single cycle of cytarabine-based consolidation chemotherapy as postremission therapy in 27 patients aged 60 to 71 years (median age, 65 years) with newly diagnosed AML in first complete remission (CR). The median follow-up from CR for all patients was 13.6 months (range, 6.0-123.1 months). The median follow-up from remission for surviving patients was 81 months (range, 41.4-123.1 months). Seven patients are alive in continuous CR, 19 died from relapse, and 1 died as a result of treatment-related infection. Leukemia-free survival and overall survival are 10.3 and 13.4 months, respectively. Actuarial leukemia-free and overall survival at 3 years are 25% +/- 9% and 28% +/- 9%, respectively. Our results demonstrate that autologous transplantation of peripheral blood progenitor cells is well tolerated and feasible for patients > or =60 years of age with AML in first CR. Future investigation should focus on a randomized study evaluating a larger group of elderly patients in first CR comparing autologous stem cell transplantation with conventional cytarabine-based consolidation chemotherapy to identify the optimal postremission therapy.

Abstract
We investigated the relative prognostic significance of cytogenetics in 635 adult acute myeloid leukemia (AML) patients 60 years of age or older treated on front-line protocols. Classification trees and tree-structured survival analysis (TSSA) were used to identify important cytogenetic groups, and their prognostic significance was then assessed in multivariable analysis (MVA). Overall, 48.5% achieved complete remission (CR); 6.6% survived at 5 years. Complex karyotypes with at least 3 abnormalities (complex > or = 3) and a group including "rare aberrations" predicted lower CR rates (25% and 30%) versus other patients (56%). Compared with complex > or = 3, the odds of CR were significantly higher for noncomplex karyotypes without rare aberrations on MVA. Cytogenetically, complex > or = 5 predicted inferior disease-free survival on TSSA, remaining significant on MVA together with white blood cell count (WBC), sex, and age. For survival, complex > or = 5, rare aberrations, and core-binding factor (CBF) abnormalities were prognostic (P < .001), with 5-year survivals of 0%, 0%, and 19.4%, respectively, and 7.5% for remaining patients. Together with WBC, marrow blasts, sex, and age, the cytogenetic groups remained significant on MVA. In conclusion, pretreatment cytogenetics adds to other prognostic factors in older AML patients. Patients with complex > or = 5 appear to benefit minimally from current treatment and are better suited for investigational therapy or supportive care.

Abstract
Outcome of patients with acute myeloid leukemia (AML) who are older than 60 years of age remains unsatisfactory, with low remission rates and poor overall survival. We have previously established the activity of clofarabine plus cytarabine in AML relapse. We have now conducted a phase 2 study of clofarabine plus cytarabine in patients aged 50 years or older with previously untreated AML. Clofarabine was given at 40 mg/m2 as a 1-hour intravenous infusion for 5 days (days 2 to 6) followed 4 hours later by cytarabine at 1 g/m2/d as a 2-hour intravenous infusion for 5 days (days 1 to 5). Of 60 patients, 29 (48%) had secondary AML, 30 (50%) had abnormal karyotypes (monosomy 5 and/or 7 in 15 [25%]), and 11 (21%) showed FLT3 abnormalities. The overall response (OR) rate was 60% (52% CR, 8% CRp). Four patients (7%) died during induction. Adverse events were mainly grade 2 or lower and included diarrhea, nausea, vomiting, mucositis, skin reactions, liver test abnormalities, and infusion-related facial flushing and headaches. Myelosuppression was common. Clofarabine plus cytarabine has activity in adult AML, achieving a good CR rate. However, survival does not appear to be improved compared with other regimens. Modifications of this combination in AML therapy of older patients warrant further evaluation.

Abstract
BACKGROUND Elderly patients with acute myeloid leukemia (AML) generally have an unfavorable clinical course and are under-represented in clinical trials. The aim of this study was to analyze the prognosis and treatment outcome of elderly AML patients. PATIENTS AND METHODS We studied 205 AML patients aged 65 years or older at our hospital. Prior to study initiation, we designated 13 variables to be analyzed for their impact on complete remission (CR) rate and overall survival (OS). RESULTS Induction regimen (standard chemotherapy) and good performance status (PS) (Eastern Cooperative Oncology Group PS 0-1) independently influenced the achievement of CR. Multivariate analysis also determined five poor prognostic factors for OS: poor PS (score 2-4), presence of comorbidities, elevated serum lactate dehydrogenase level (> or =2x upper normal limit), extreme leukocytosis (> or =100 x 10(9)/l) and marked thrombocytopenia (< or =20 x 10(9)/l). Age was not an independent contributing factor in terms of either CR attainment or OS duration. Low-risk patients, who possessed one or less non-leukocytosis poor prognostic factor, had significantly longer disease-free survival and OS than their high-risk counterparts. CONCLUSIONS Elderly AML patients should be risk-stratified at diagnosis. Anthracycline-based induction chemotherapy would be the best therapeutic option for such patients.
