Abstract
OBJECTIVE To investigate efficacy and prognostic factors in the treatment of adult newly-diagnosed acute myeloid leukemia (AML) with or without allogeneic hematopoietic stem cell transplantation (Allo-HSCT). METHODS We retrospectively analyzed 668 patients with newly-diagnosed AML (non-M3 type) in the Department of Hematology at Shanghai Changhai Hospital from January 2012 to December 2021. Based on different induction chemotherapy regimens, patients were categorized into an IA (idarubicin, IDA + cytarabine, Ara-C) (3 + 7, regimen) group (n = 303) and a DA (daunorubicin, DNR + cytarabine, Ara-C) (3 + 7, regimen) group (n = 365) with or without allo-HSCT. Minimal residual disease (MRD), complete response (CR), overall response rate (ORR), progression-free survival (PFS), overall survival (OS), and adverse effects (AE) were analyzed and compared. Characteristics significantly associated with overall or progression-free survival (OS or PFS) upon univariate analysis were subsequently included in a Cox proportional hazard model. RESULTS This study used data from 668 AML patients. After induction therapy, the CR rate in the IA group was 70.63% and ORR was 79.87%, which were significantly higher than those in the DA group (with a CR rate of 56.99% and an ORR of 70.14%) (P = 0.0002 and P = 0.0035, respectively). There were no significant differences in drug safety between the two chemotherapy regimens used in IA and DA (P > 0.05). The recurrence rate was lower in patients with an MRD < 0.001 than in patients with an MRD ≥ 0.001. A continuous negative MRD during the period is significant because it is associated with prolonged OS and PFS of AML patients. Data from 100 patients in the two groups who underwent allo-HSCT were analyzed using univariate analysis and the Cox proportional hazards model. From the multivariate analysis, MRD was found to be the only independent predictor of OS (P = 0.042; HR 1; 95%CI 0.00-0.76). CONCLUSION In the treatment of adult AML patients, IA regimen is associated with a high CR rate and ORR rate and does not increase treatment-related toxicity. IA regimen prolongs OS and PFS in AML patients and reduces the likelihood of leukemia cells' subsequent infiltration into the central nervous system. There is a high correlation between the level of MRD after treatment and the patient's bone marrow recurrence. To obtain superior treatment effects for patients undergoing allo-HSCT, the MRD should be reduced to less than 0.001 before pretreatment. A negative MRD before allo-HSCT can prolong OS in patients with AML. We examined the clinical characteristics and outcomes of AML patients in China, finding novel information on prognostic factors and primary treatment of AML that may be applicable in routine clinical practice.

Abstract
This study aimed to examine the characteristics and treatment outcomes of patients with TP53-mutant acute myeloid leukaemia (AML) and to explore potential prognostic factors. This retrospective analysis included 130 patients diagnosed with TP53-mutant AML at the Fujian Medical University Union Hospital between January 2016 and June 2023. Patients' ages ranged from 17 to 80 years, with a median age of 59 years. The proportions of de novo, therapy-related, and secondary AML cases were 71.5%, 7.7%, and 20.8%, respectively. Complex karyotypes were observed in 60.6% of patients, and the proportions of -5 or del(5q), -7 or del(7q), and - 17 or del(17p) were 41.7%, 27.9% and 14.4%, respectively. DNA methylation- and myelodysplasia-related (MR) gene mutations were observed in 36.9% and 25.4% of patients, respectively. These patients showed poor survival, with a median overall survival (OS) of 4.5 months, a 1-year OS rate of 32.5%, a 3-year OS rate of 18.8%, and a 5-year OS rate of 11.3%. The complete response rates for intensive chemotherapy (IC), hypomethylating agent (HMAs)-based therapies, and azacitidine plus venetoclax were 35.7%, 22.2%, and 37.5%, respectively. Patients who did or did not receive allogeneic haematopoietic stem cell transplantation (allo-HSCT) had similar prognoses (median OS: 6.0 vs. 3.9 months; P = 0.6415). Multivariate analysis indicated that MR gene mutations is an independent favorable prognostic factor of OS (HR = 0.366, 95% CI: 0.181-0.738, P = 0.005). In conclusion, patients with TP53-mutant AML have poor prognoses under current treatment strategies and MR gene mutations are associated with a more favorable survival. Therefore, further studies are needed to improve the survival rates in this population.

Abstract
Venetoclax plus 3 + 7 daunorubicin and cytarabine chemotherapy (DAV) has shown safety and efficacy in eligible patients with newly diagnosed acute myeloid leukemia (AML). However, there are no direct comparisons between DAV and 3 + 7 daunorubicin and cytarabine chemotherapy (DA) alone. We performed a propensity score-matched analysis to compare the outcomes of DAV group with historical DA group and identify the clinical and molecular characteristics of patients who might benefit from the DAV regimen. The DAV group had a higher Complete remission (CR) rate than the DA group (90% vs. 55%, p = 0.008). 25 (96%) patients in the DAV group had a higher MRD-negative CRc rate compared with 13 (62%) patients in the DA group (p = 0.006). After a median follow-up duration of 19.15 (IQR 17.13-21.67) months, the DAV group had an improved overall survival (p = 0.001) and event-free survival (p = 0.069), but not disease-free survival (p = 0.136). Collectively, DAV regimen induced high CR rates and deep MRD-negative CRc rates after one cycle of induction therapy, as well as prolonged the overall survival, in young adult patients with AML who were eligible for intensive chemotherapy. The addition of venetoclax to intensive chemotherapy should be considered in the future to achieve better survival advantages in eligible AML patients.

Abstract
BACKGROUND & AIMS Acute myeloid leukaemia (AML) chemotherapy has been reported to impact gut microbiota composition. In this study, we investigated using a multi -omics strategy the changes in the gut microbiome induced by AML intense therapy and their association with gut barrier function and cachectic hallmarks. METHODS 10 AML patients, allocated to standard induction chemotherapy (SIC), were recruited. Samples and data were collected before any therapeutic intervention (T0), at the end of the SIC (T1) and at discharge (T4). Gut microbiota composition and function, markers of inflammation, metabolism, gut barrier function and cachexia, as well as faecal, blood and urine metabolomes were assessed. RESULTS AML patients demonstrated decreased appetite, weight loss and muscle wasting during hospitalization, with an incidence of cachexia of 50%. AML intensive treatment transiently impaired the gut barrier function and led to a long-lasting change of gut microbiota composition characterized by an important loss of diversity. Lactobacillaceae and Campylobacter concisus were increased at T1 while Enterococcus faecium and Staphylococcus were increased at T4. Metabolomics analyses revealed a reduction in urinary hippurate and faecal bacterial amino acid metabolites (bAAm) (2-methylbutyrate, isovalerate, phenylacetate). Integration using DIABLO revealed a deep interconnection between all the datasets. Importantly, we identified bacteria which disappearance was associated with impaired gut barrier function (Odoribacter splanchnicus) and body weight loss (Gemmiger formicilis), suggesting these bacteria as actionable targets. CONCLUSION AML intensive therapy transiently impairs the gut barrier function while inducing enduring alterations in the composition and metabolic activity of the gut microbiota that associate with body weight loss.

Abstract
To compare efficacy between homoharringtonine combined with cytarabine and aclarubicin (HAA) and idarubicin and cytarabine (IA) regimens as first induction chemotherapy in patients with core binding factor acute myeloid leukemia (CBF-AML). Cox regression model and propensity score matching (PSM) were used to identify the regimen associated with a better remission rate and outcomes. In total, 374 patients with CBF-AML (243 with RUNX1::RUXN1T1 and 131 with CBFB::MYH11) were included in this study. The patients received the HAA or IA regimen (187 each) as the first induction therapy. For patients with RUNX1::RUXN1T1, multivariate analyses showed that the HAA regimen was significantly associated with a higher CR/CRi rate after the first induction (hazard ratio [HR] = 5.3 [95% CI 2.3, 12.2]; p < 0.001) and more favorable relapse-free survival (RFS) (HR = 0.5 [0.3, 0.8], p = 0.01). In PSM analysis, the HAA regimen also had a higher CR/CRi rate (96% vs. 77%, p < 0.001), especially for those harboring wild-type KIT (KITWT) (96% vs. 83%, p = 0.02) or non-D816 KIT mutation (100% vs. 63%, p = 0.002), as well as more favorable RFS (p = 0.01), compared with the IA regimen. However, there was no difference in the remission rate or outcomes between the two regimens for patients with CBFB::MYH11. The HAA regimen as first induction chemotherapy resulted in a higher CR/CRi rate in AML patients with RUNX1::RUNX1T1, especially those harboring KITWT and non-D816 KIT mutation, and a more favorable RFS compared with the IA regimen. The efficacy between the two regimens did not differ in those with CBFB::MYH11.

Abstract
INTRODUCTION Cytarabine and anthracycline combination therapy (7 + 3 regimen) is the standard care for induction chemotherapy in adult patients with acute myeloid leukemia (AML). Although this intensive regimen achieves a high response rate, it is highly toxic, especially in elderly or frail patients. Hypomethylating agents approved initially for high-risk myelodysplastic syndrome had longer survival times than conventional care in elderly patients with newly diagnosed AML. AREAS COVERED We summarize the latest information regarding induction therapy using hypomethylating agents (azacitidine and decitabine) for newly diagnosed AML. EXPERT OPINION For untreated patients ineligible for an intensive regimen, a phase III trial exhibited the survival benefit of adding the highly selective BCL2 inhibitor venetoclax to azacitidine. The National Comprehensive Cancer Network guidelines recommend azacitidine or decitabine plus venetoclax as an option for patients with poor-risk AML, including those with TP53 mutations and AML with the cytogenetic features of myelodysplastic syndrome. Future studies should evaluate positioning this combination as an induction therapy for younger patients eligible for hematopoietic stem cell transplantation. Without randomized trials, propensity score matching analysis suggested a comparable prognosis between azacitidine combination and intensive chemotherapy. Considering the feasibility of a doublet regimen incorporating azacitidine, a triplet regimen should be examined.

Abstract
The word Leukemia was coined nearly 200 years ago by Rudolf Virchow. Once a death sentence, Acute Myeloid Leukemia (AML) is now a treatable condition. The introduction of "7 + 3" chemotherapy, originally reported from the Roswell Park Memorial institute in Buffalo, New York, in 1973, changed the treatment paradigm for AML. About twenty-seven years later, FDA approved the first targeted agent, gemtuzumab, to be added to this backbone. During the last seven years, we have had ten new drugs approved for the management of patients with AML. Work by many dedicated scientists led to AML achieving the elite status of being the first cancer to have the whole genome sequenced using next-generation sequencing. In the year 2022, we witnessed the introduction of new classification systems for AML by the international consensus classification and the world health organization, both emphasizing molecular classification of the disease. In addition, the introduction of agents such as venetoclax and targeted therapies have changed the treatment paradigm in older patients ineligible for intensive therapy. In this review, we cover the rationale and evidence behind these regimens and provide insights into the newer agents.

Abstract
BACKGROUND Venetoclax (Ven) combined with intensive chemotherapy was proven effective in the management of acute myeloid leukemia (AML). However, the severe and prolonged myelosuppression remains a concern to worry about. To explore more appropriate combination regimens, we designed Ven combining daunorubicin and cytarabine (DA 2 + 6) regimen as induction therapy, aimed to evaluate the effectiveness and safety in adults de novo AML. METHODS A phase 2 clinical trial was performed in 10 Chinese hospitals to investigate Ven combined with daunorubicin and cytarabine (DA 2 + 6) in patients with AML. The primary endpoints were overall response rate (ORR), comprising of complete remission (CR), complete remission with incomplete blood cell count recovery (CRi), and partial response (PR). Secondary endpoints included measurable residual disease (MRD) of bone marrow assessed by flow cytometry, overall survival (OS), event-free survival (EFS), disease-free survival (DFS), and the safety of regimens. This study is a currently ongoing trial listed on the Chinese Clinical Trial Registry as ChiCTR2200061524. RESULTS Overall, 42 patients were enrolled from January 2022 to November 2022; 54.8% (23/42) were male, and the median age was 40 (range, 16-60) years. The ORR after one cycle of induction was 92.9% (95% confidence interval [CI], 91.6-94.1; 39/42) with a composite complete response rate (CR + CRi) 90.5% (95% CI, 89.3-91.6, CR 37/42, CRi 1/42). Moreover, 87.9% (29/33) of the CR patients with undetectable MRD (95% CI, 84.9-90.8). Grade 3 or worse adverse effects included neutropenia (100%), thrombocytopenia (100%), febrile neutropenia (90.5%), and one mortality. The median neutrophil and platelet recovery times were 13 (5-26) and 12 (8-26) days, respectively. Until Jan 30, 2023, the estimated 12-month OS, EFS, and DFS rates were 83.1% (95% CI, 78.8-87.4), 82.7% (95% CI, 79.4-86.1), and 92.0% (95% CI, 89.8-94.3), respectively. CONCLUSION Ven with DA (2 + 6) is a highly effective and safe induction therapy for adults with newly diagnosed AML. To the best of our knowledge, this induction therapy has the shortest myelosuppressive period but has similar efficacy to previous studies.

Abstract
Bleeding in patients with acute myeloid leukemia (AML) receiving intensive induction chemotherapy is multifactorial and contributes to early death. We sought to define the incidence and risk factors of grade 4 bleeding to support strategies for risk mitigation. Bleeding events were retrospectively assessed between day-14 and day +60 of induction treatment according to the World Health Organization (WHO) bleeding assessment scale, which includes grade 4 bleeding as fatal, life-threatening, retinal with visual impairment, or involving the central nervous system. Predictors were considered pretreatment or prior to grade 4 bleeding. Using multivariable competing-risk regression analysis with grade 4 bleeding as the primary outcome, we identified risk factors in the development cohort (n = 341), which were tested in an independent cohort (n = 143). Grade 4 bleeding occurred in 5.9% and 9.8% of patients in the development and validation cohort, respectively. Risk factors that were independently associated with grade 4 bleeding included baseline platelet count ≤40 × 109/L compared with >40 × 109/L, and baseline international normalized ratio of prothrombin time (PT-INR) >1.5 or 1.3 > 1.5 compared with ≤1.3. These variables were allocated points, which allowed for stratification of patients with low- and high-risk for grade 4 bleeding. Cumulative incidence of grade 4 bleeding at day+60 was significantly higher among patients with high- vs low-risk (development: 31 ± 7% vs 2 ± 1%; P < .001; validation: 25 ± 9% vs 7 ± 2%; P = .008). In both cohorts, high bleeding risk was associated with disseminated intravascular coagulation (DIC) and proliferative disease. We developed and validated a simple risk model for grade 4 bleeding, which enables the development of rational risk mitigation strategies to improve early mortality of intensive induction treatment.

Abstract
Objective: To compare the efficacy of two induction regimens, namely, idarubicin combined with cytarabine (IA) versus the combination of homoharringtonine, daunorubicin, and cytarabine (HAD) , in adult patients with newly diagnosed de novo acute myeloid leukemia (AML) . Methods: From May 2014 to November 2019, 199 patients diagnosed with AML receiving either the IA or HAD regimens were assessed for overall survival (OS) , relapse-free survival (RFS) , as well as the CR rate and the MRD negative rate after induction therapy. The differences in prognosis between the two induction therapy groups was assessed according to factors, including age, white blood cell (WBC) count, NPM1 mutation, FLT3-ITD mutation, 2017 ELN risk stratification, CR(1) transplantation, and the use of high-dose cytarabine during consolidation therapy, etc. Results: Among the 199 patients, there were 104 males and 95 females, with a median age of 37 (15-61) years. Ninety patients received the IA regimen, and 109 received the HAD regimen. Comparing the efficacy of the IA and HAD regimens, the CR rates after the first induction therapy were 71.1% and 63.3%, respectively (P=0.245) , and the MRD negative rates after the first induction therapy were 53.3% and 48.6%, respectively (P=0.509) . One patient in the IA group and two in the HAD group died within 60 days after induction. The two-year OS was 61.5% and 70.6%, respectively (P=0.835) , and the two-year RFS was 51.6% and 57.8%, respectively (P=0.291) . There were no statistically significant differences between the two groups. Multivariate analysis showed that the ELN risk stratification was an independent risk factor in both induction groups; CR(1) HSCT was an independent prognostic factor for OS and RFS in the IA patients and for RFS in the HAD patients but not for OS in the HAD patients. Age, WBC level, NPM1 mutation, and FLT3-ITD mutation had no independent prognostic significance. Conclusion: The IA and HAD regimens were both effective induction regimens for AML patients.

Abstract
The history of human acute myeloid leukemia stem cells (AMLSCs) began in a seminal study performed by Lapidot and Dick, proving that only CD34+CD38- human primary acute myeloid leukemia (AML) cells can repopulate in severe combined immunodeficient mice. The concept of leukemic stem cells (LSCs) has impeded a huge change in the treatment strategy against AML from killing proliferating leukemic cells to eradicating quiescent/dormant LSCs. As next-generation sequencing technologies have developed, multiple and recurrent genetic mutations have been discovered in large cohorts of patients with AML, and the updated understanding of leukemogenesis has improved the old concept of LSC to a revised version of a serial developmental model of LSC; that is, pre-LSCs are generated as seeds by the first hit on epigenetic regulators, and then, leukemia-initiating LSCs emerge from seeds by the second hits on genes involved in transcription and signaling. Dreams for universal and targetable AMLSC biomarker sparing healthy hematopoietic stem cells have weakened after the confrontation of significant heterogeneity of AMLSCs from genomic and immunophenotypic viewpoints. However, there is still hope for effective targets for AMLSCs since there is evidence that grouped gene signatures, such as 17-gene LSC score, and common epigenetic signatures, such as HOXA clusters, independent of various gene mutations, exist. Recently, the LSC niche in the bone marrow has been actively investigated and has expanded our knowledge of the physiology and vulnerability of AMLSCs. Presently, an applicable treatment that always works in AMLSCs is lacking. However, we will find a way, we always have.

Abstract
BACKGROUND Achievement of initial remission remains the most important clinical factor predicting long term survival in acute myeloid leukemia (AML) patients treated with intensive chemotherapy. Yet, whether the patient subset in need of a second cycle of intensive induction chemotherapy to reach remission experiences inferior outcomes compared to patients reaching remission after a single cycle of therapy, remains uncertain. PATIENTS AND METHODS Retrospective analysis of 302 consecutive AML patients treated with intensive induction chemotherapy in our institution in 2007-2020. RESULTS Median patient age was 55 years with a median follow-up duration of 23 months. In terms of European LeukemiaNet (ELN) 2017 classification, 122 patients (40%) were designated as favorable risk disease, 108 patients (36%) were intermediate risk, and 71 patients (24%) were adverse risk. A hundred and seventy-seven patients (60%) attained remission following initial chemotherapy while 58 patients (20%) required an additional cycle of intensive chemotherapy for remission. Patients requiring 2 cycles to reach remission were less likely to be NPM1 mutated (33% versus 51%; P=.025) or be in the ELN 2017 favorable risk category (25% versus 57%; P<.001). In multivariate analysis achievement of remission following 2 cycles of intensive compared with a single cycle resulted in significantly inferior survival [hazard ratio (HR)=1.67, 95% CI, 1.07-2.59; P=.025] whereas leukemia-free survival was not significantly impacted (HR=1.26, 95% CI, 0.85-1.85) (P=.23). Relapse rates also did not differ to a significant degree between groups (45% versus 47%, P=.8). CONCLUSION Attainment of an early remission significantly impacts long term survival in AML patients.

Abstract
Idarubicin 12 mg/m2 has been recommended as a standard induction therapy for acute myeloid leukemia (AML). It is unknown whether a higher dose of idarubicin can improve the remission rate. This phase 2 prospective single-arm study enrolled 45 adults with newly diagnosed AML between September 2019 and May 2021 (NCT 04,069,208). Induction therapy included administration of idarubicin 14 mg/m2 for 3 days and cytarabine 100 mg/m2 every 12 h subcutaneously for 7 days. The primary endpoint was the composite complete response rate (complete response (CR) plus complete response with incomplete blood count recovery (CRi)). The median age was 45 years (range 14-60 years). Forty (88.9%) patients had CR or CRi, including 39 patients with CR and 1 patient with CRi after one course of induction therapy. The median times to recovery of absolute neutrophil and platelet counts were 21 days. Only 1 patient died of intracranial hemorrhage during induction therapy. After a median follow-up of 14 months (range 3.5-24 months), the estimated 18-month overall survival and disease-free survival (DFS) were 66.9% and 57.5%, respectively. In conclusion, idarubicin 14 mg/m2 plus cytarabine was a safe and efficient intensive regimen for younger and fit patients with newly diagnosed AML.

BACKGROUND Adolescents and young adult (AYA) acute myeloid leukemia (AML) outcomes remain poor. The impact of locus of care (LOC; adult vs pediatric) in this population is unknown. PROCEDURE The IMPACT cohort comprises detailed data for all Ontario, Canada, AYA aged 15-21 years diagnosed with AML between 1992 and 2012, linked to population-based health administrative data. We determined the impact of LOC on event-free survival (EFS) and overall survival (OS), treatment-related mortality (TRM), and relapse/progression. RESULTS Among 140 AYA, 51 (36.4%) received therapy at pediatric centers. The five-year EFS and OS for the whole cohort were 35.0% ± 4.0% and 53.6% ± 4.2%. Cumulative doses of anthracycline were higher among pediatric center AYA [median 355 mg/m2 , interquartile range (IQR) 135-492 vs 202 mg/m2 , IQR 140-364; P = 0.003]. In multivariable analyses, LOC was not predictive of either EFS [adult vs pediatric center hazard ratio (HR) 1.3, 95% confidence interval (CI) 0.8-2.2, P = 0.27] or OS (HR 1.0, CI 0.6-1.6, P = 0.97). However, patterns of treatment failure varied; higher two-year incidence of TRM in pediatric centers (23.5% ± 6.0% vs.10.1% ± 3.2%; P = 0.046) was balanced by lower five-year incidence of relapse/progression (33.3% ± 6.7% vs 56.2% ± 5.3%; P = 0.002). CONCLUSIONS AYA AML survival outcomes did not vary between pediatric and adult settings. Causes of treatment failure were different, with higher intensity pediatric protocols associated with higher TRM but lower relapse/progression. Careful risk stratification and enhanced supportive care may be of substantial benefit to AYA with AML by allocating maximal treatment intensity to patients who most benefit while minimizing the risk of TRM.

Abstract
BACKGROUND Patients diagnosed with acute myeloid leukemia with a FLT3 mutation (FLT3+ AML) have historically had poor outcomes. While the addition of the FLT3 inhibitors to induction therapy has been shown to improve survival outcomes in FLT3+ AML, interactions and overlapping toxicities between FLT3 inhibitors and standard of care medications used during induction therapy (e.g. azole antifungals, anthracyclines) and logistical barriers have complicated their use. To avoid these concerns, our institution has opted to defer initiation of midostaurin until after completion of induction therapy. However, to our knowledge no study confirming the effectiveness of this strategy for real world FLT3 inhibitor use has been published. METHODS We performed a single center, propensity-score matched, retrospective cohort study characterizing efficacy and safety of our strategy for use of FLT3 inhibitors in the treatment of FLT3+ AML. The primary outcome was median event-free survival (EFS), while secondary endpoints included median overall survival (OS), overall response rate (ORR), 30-day mortality, duration of neutropenia, duration of thrombocytopenia, consolidation cycle delays, documented infections, and all-cause hospital readmission. RESULTS A total of 83 FLT3+ AML patients treated with intensive induction therapy were included in the study, of whom 48 were propensity-score matched and analyzed. Baseline characteristics were similar between the patients who received a FLT3 inhibitor after induction therapy and the historical control arm. Median EFS was not significantly different but compared favorably between the FLT3 inhibitor cohort and historical controls (not reached vs 8 months, p = 0.343) with 18-month EFS of 54% and 43% for the two cohorts, respectively. Similarly, no significant differences were noted with regard to median OS (not reached vs 28.7 months, p = 0.752), ORR (79.2% vs 79.2%), or safety outcomes between groups. CONCLUSION Compared to historical controls, addition of a FLT3 inhibitor to intensive chemotherapy post-induction may improve EFS or OS in a real world patient cohort with longer follow-up and a larger sample size. The omission of midostaurin in induction allowed for the use of an azole antifungal and the intensification of anthracycline dose may have contributed to high remission rates in both groups.

Abstract
Objective The clinical characteristics and therapeutic strategy in acute myeloid leukemia (AML) are influenced by patients’ age. We evaluated the impact of age on remission induction therapy for AML. Methods We retrospectively analyzed 3,011 adult AML patients identified from a nationwide database between January 2007 and December 2011. Results Three hundred twenty-nine (10.9%) acute promyelocytic leukemia (APL) and 2,682 (89.1%) non-APL patients were analyzed. The median age was 51 years and 55% of patients were male. Six hundred twenty-three patients (21%) were at favorable risk, 1522 (51%) were at intermediate risk, and 743 (25%) were at poor risk. As the age increased, the proportion of those at favorable risk and who received induction chemotherapy decreased. After induction therapy, complete response (CR) was achieved in 81.5% (243/298) of APL and 62.4% (1,409/2,258) of non-APL patients; these rates decreased as the age increased, with an obvious decrement in those older than 60 years. The median overall survival of non-APL patients was 18.7 months, while that of APL patients was not reached, with a 75% five-year survival rate. Conclusions Age impacts both the biology and clinical outcomes of AML patients. Further studies should confirm the role of induction remission chemotherapy by age group.

Abstract
BACKGROUND The optimal approach to combine gemtuzumab-ozogamicin (GO) with various chemotherapy backbones and other newer agents safely remains to be determined. MATERIALS AND METHODS We performed a retrospective analysis of the safety and outcomes of adult patients with newly diagnosed acute myeloid leukemia (AML) treated with GO with intensified versus standard anthracycline doses (daunorubicin dose 90 mg/m2 vs 60 mg/m2) ± FLT3 inhibitors. The χ2 test and Mann-Whitney U test were used to compare categorical and continuous data. Survival estimates were calculated by Kaplan-Meier method and survival comparisons made using log-rank test. RESULTS We report a 97% overall response rate in 34 patients with newly diagnosed AML with a median age of 54 years (19-75 years) treated with GO and standard induction. The 11 patients (100%) receiving GO plus daunorubicin dose 90 mg/m2 as part of 7 + 3 induction achieved complete response versus 91% (20/22) complete response in the standard daunorubicin dose group (P = NS). No increased toxicity was noted with the higher daunorubicin dose or when GO and 7 + 3 were combined with FLT3 inhibitors in 3 younger patients (<60 years). Two older patients treated with GO+7 + 3 and FLT3i experienced grade 3 or higher cardiotoxicity. We observed a longer estimated event-free survival for patients with newly diagnosed AML in our cohort (median, 24 months; 95% confidence interval, 17.2 to not reached) compared with historical data. CONCLUSION We demonstrate that anthracycline dose intensification with GO may offer higher response rates without increased toxicity in younger patients presenting with de novo AML across European Leukemia Net risk categories.

Abstract
Induction chemotherapy (7 + 3 regimen) remains the gold standard for patients with acute myeloid leukemia (AML) but is responsible for gut damage leading to several complications such as bloodstream infection (BSI). We aimed to investigate the impact of induction chemotherapy on the intestinal barrier of patients with AML and in wild-type mice. Next, we assessed the potential benefit of strengthening the mucosal barrier in transgenic mice releasing a recombinant protein able to reinforce the mucus layer (Tg222). In patients, we observed a decrease of plasma citrulline, which is a marker of the functional enterocyte mass, of short-chain fatty acids and of fecal bacterial load, except for Escherichia coli and Enterococcus spp., which became dominant. Both the α and β-diversities of fecal microbiota decreased. In wild-type mice, citrulline levels decreased under chemotherapy along with an increase of E. coli and Enterococcus spp load associated with concomitant histologic impairment. By comparison with wild-type mice, Tg222 mice, 3 days after completing chemotherapy, had higher citrulline levels, a faster healing epithelium, and preserved α-diversity of their intestinal microbiota. This was associated with reduced bacterial translocations. Our results highlight the intestinal damage and the dysbiosis induced by the 7 + 3 regimen. As a proof of concept, our transgenic model suggests that strengthening the intestinal barrier is a promising approach to limit BSI and improve AML patients' outcome.

Abstract
Mutations in the FMS-like tyrosine kinase 3 (FLT3) gene arise in 25-30% of all acute myeloid leukemia (AML) patients. These mutations lead to constitutive activation of the protein product and are divided in two broad types: internal tandem duplication (ITD) of the juxtamembrane domain (25% of cases) and point mutations in the tyrosine kinase domain (TKD). Patients with FLT3 ITD mutations have a high relapse risk and inferior cure rates, whereas the role of FLT3 TKD mutations still remains to be clarified. Additionally, growing research indicates that FLT3 status evolves through a disease continuum (clonal evolution), where AML cases can acquire FLT3 mutations at relapse - not present in the moment of diagnosis. Several FLT3 inhibitors have been tested in patients with FLT3-mutated AML. These drugs exhibit different kinase inhibitory profiles, pharmacokinetics and adverse events. First-generation multi-kinase inhibitors (sorafenib, midostaurin, lestaurtinib) are characterized by a broad-spectrum of drug targets, whereas second-generation inhibitors (quizartinib, crenolanib, gilteritinib) show more potent and specific FLT3 inhibition, and are thereby accompanied by less toxic effects. Notwithstanding, all FLT3 inhibitors face primary and acquired mechanisms of resistance, and therefore the combinations with other drugs (standard chemotherapy, hypomethylating agents, checkpoint inhibitors) and its application in different clinical settings (upfront therapy, maintenance, relapsed or refractory disease) are under study in a myriad of clinical trials. This review focuses on the role of FLT3 mutations in AML, pharmacological features of FLT3 inhibitors, known mechanisms of drug resistance and accumulated evidence for the use of FLT3 inhibitors in different clinical settings.

Abstract
Acute myeloid leukemia (AML) is the most common form of acute leukemia among adults and accounts for the largest number of annual deaths due to leukemias in the United States. Recent advances have resulted in an expansion of treatment options for AML, especially concerning targeted therapies and low-intensity regimens. This portion of the NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for AML focuses on the management of AML and provides recommendations on the workup, diagnostic evaluation and treatment options for younger (age <60 years) and older (age ≥60 years) adult patients.

Abstract
Here we evaluated whether sequential high-dose chemotherapy (sHD) increased the early complete remission (CR) rate in acute myelogenous leukemia (AML) compared with standard-intensity idarubicin-cytarabine-etoposide (ICE) chemotherapy. This study enrolled 574 patients (age, 16-73 years; median, 52 years) who were randomly assigned to ICE (n = 286 evaluable) or sHD (2 weekly 3-day blocks with cytarabine 2 g/m2 twice a day for 2 days plus idarubicin; n = 286 evaluable). Responsive patients were risk-stratified for a second randomization. Standard-risk patients received autograft or repetitive blood stem cell-supported high-dose courses. High-risk patients (and standard-risk patients not mobilizing stem cells) underwent allotransplantation. CR rates after 2 induction courses were comparable between ICE (80.8%) and sHD (83.6%; P = .38). sHD yielded a higher single-induction CR rate (69.2% vs 81.5%; P = .0007) with lower resistance risk (P < .0001), comparable mortality (P = .39), and improved 5-year overall survival (39% vs 49%; P = .045) and relapse-free survival (36% vs 48%; P = .028), despite greater hematotoxicity delaying or reducing consolidation blocks. sHD improved the early CR rate in high-risk AML (odds ratio, 0.48; 95% confidence interval [CI], 0.31-0.74; P = .0008) and in patients aged 60 years and less with de novo AML (odds ratio, 0.46; 95% CI, 0.27-0.78; P = .003), and also improved overall/relapse-free survival in the latter group (hazard ratio, 0.70; 95% CI, 0.52-0.94; P = .01), in standard-risk AML, and postallograft (hazard ratio, 0.61; 95% CI, 0.39-0.96; P = .03). sHD was feasible, effectively achieved rapid CR, and improved outcomes in AML subsets. This study is registered at www.clinicaltrials.gov as #NCT00495287.

Abstract
A subset of acute myeloid leukemia (AML) arises either from an antecedent myeloid malignancy (secondary AML, sAML) or as a complication of DNA-damaging therapy for other cancers (therapy-related myeloid neoplasm, t-MN). These secondary leukemias have unique biological and clinical features that distinguish them from de novo AML. Over the last decade, molecular techniques have unraveled the complex subclonal architecture of sAML and t-MN. In this review, we compare and contrast biological and clinical features of de novo AML with sAML and t-MN. We discuss the role of genetic mutations, including those involved in RNA splicing, epigenetic modification, tumor suppression, transcription regulation, and cell signaling, in the pathogenesis of secondary leukemia. We also discuss clonal hematopoiesis in otherwise healthy individuals, as well as in the context of another malignancy, and how it challenges the conventional notion of sAML/t-MN. We conclude by summarizing the current and emerging treatment strategies, including allogenic transplant, in these complex scenarios.

Abstract
We provide a long-term evaluation of patients enrolled in the EORTC/GIMEMA AML-10 trial which included a total of 2157 patients, 15-60 years old, randomized to receive either daunorubicin (DNR, 50 mg/m2 ), mitoxantrone (MXR, 12 mg/m2 ), or idarubicin (IDA, 10 mg/m2 ) in addition to standard-dose cytarabine and etoposide for induction chemotherapy and intermediate dose cytarabine for consolidation. Younger patients who reached complete remission with complete (CR) or incomplete (CRi) recovery were then scheduled to receive an allogeneic hematopoietic stem cell transplantation (HSCT). That was if they had a HLA-identical sibling donor; in all other cases, an autologous HSCT had to be administered. At an 11-year median follow-up, the 5-year, 10-year and 15-year overall survival (OS) rates were 33.2%, 30.1% and 28.0%, respectively. No significant difference between the three randomized groups regarding OS was observed (P = .38). In young patients, 15-45 years old, no treatment difference (P = .89) regarding OS was observed, while in patients 46-60 years old, MXR and IDA groups had a trend for a longer OS as compared to the DNR group (P = .029). Among younger patients without a favorable MRC cytogenetic risk subgroup who achieved a CR/CRi after induction chemotherapy, those with a HLA-identical sibling donor had higher 10-year and 15-year OS rates than those without. In older patients who reached CR/CRi, the long-term outcomes of those with or without a donor was similar. In conclusion, long-term outcomes of the study confirmed similar OS in the three randomized groups in the whole cohort of patients.

Abstract
Invasive fungal infections (IFI) are a significant source of morbidity and mortality for patients with acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS). Given the heterogeneity of the population receiving hypomethylating agents (HMA), it is difficult for clinicians to accurately assess their patients' risk of infection. Literature on the incidence of IFI following HMA is limited to several studies of azacitidine. The primary objective of this retrospective study was to establish the incidence of IFI in HMA treated AML/MDS patients at a large U.S. comprehensive cancer center. Secondary objectives included comparing incidence of IFI among pre-specified subgroups to identify potential risk factors for IFI. Two hundred three patients with AML, intermediate to very high risk MDS or chronic myelomonocytic leukemia who received at least two cycles of HMA were included. The incidence of IFI, as defined by the European Organization for Research and Treatment of Cancer / Invasive Fungal Infections Cooperative Group criteria, was 9.6%, with 20 IFI diagnosed following HMA (three proven, four probable, 13 possible). Among the proven cases of IFI, molds included Scedosporium and Fusarium spp. Eleven patients who developed IFIs were neutropenic upon initiating HMA. The majority (17/20) of infections occurred during the first four cycles. Given this incidence, mold-active prophylaxis can be considered in patients who are neutropenic at the start of therapy.

Abstract
OBJECTIVE To ascertain the efficacy and safety of daunorubicin combined with cytarabine comparing with idarubicin combined with cytarabine as a standard induction therapy for acute Myeloid leukemia by a meta-analysis. METHODS The randomized controlled trials included were retrieved from PubMed, Embase, and Cochrane library. We evaluated and cross-checked the randomized clinical trials (RCTs) comparing daunorubicin combined with cytarabine (DA) and idarubicin combined with cytarabine (IA) by two reviewers independently according to Cochrane Handbook for Systematic Reviewers of Interventions. The data of meta-analysis was conducted using Review Manager 5.3 and Stata 12.0 software. RESULTS A total of 6 studies containing 3140 patients were included. The primary outcomes were complete remission (CR), CR in one course (CR1), CR in two courses (CR2), overall survival (OS), and relapse rate. The secondary outcomes included adverse events and cytogenetic risk in subgroup analyses. IA showed a statistically significant in CR (RR = 1.05; 95%CI = 1.00-1.09, P = .03) and CR1 (RR = 1.11; 95%CI = 1.04-1.18, P = .003), but not in CR2 (RR = 0.97; 95%CI = 0.77-1.24, P = .83), and relapse rate (RR = 1.08; 95%CI = 0.98-1.43, P = .08). In high dose daunorubicin group, OS was significantly improved with IA compared to DA (HR = 0.89, 95%CI = 0.8-1.0, P = .041, I = 0). At grade 3/4 adverse events, the difference between IA and DA was not statistically significant (infection, P = .28; cardiac toxicity, P = .15; bleeding, P = .29). In the subgroup analysis, the genotypes of the IA and DA groups were not statistically significant for comparison of CR between the two groups (P = .07). CONCLUSION This meta-analysis showed that IA had a better efficacy in the treatment of acute myeloid leukemia than DA, even with increased doses of DA. The OS of a standard dose of IA patients was longer than that of DA patients. Our research shows that anthracycline dose intensification of daunorubicin is of no clinically relevant benefit in AML patients comparing with a standard dose of IA. When it comes to adverse drug reactions, it is not a significant difference. Therefore, in clinical practice, IA should be the first choice for induction regimen in patients with acute myeloid leukemia.

Abstract
PURPOSE OF REVIEW Venetoclax with backbone therapies have shown promising efficacy for newly diagnosed, previously untreated, older, unfit acute myeloid leukemia patients. This review discusses this data and potential reasons for the efficacy of these venetoclax-based combinations. RECENT FINDINGS Venetoclax with hypomethylators and low-dose cytarabine have resulted in high response rates, promising response durations, and significant overall survival in relatively small, uncontrolled studies. There is emerging data that these responses are due to the effective targeting of leukemia stem cells through an alteration of the metabolic environment that is poorly tolerated by this population. SUMMARY Venetoclax with a backbone therapy in older, untreated patients with acute myeloid leukemia has shown promising efficacy in preliminary clinical trials, and at least partially works through a novel mechanism that can target the leukemia stem cell population. Future investigations will help elucidate the mechanism and the contributions being made by each agent in the regimen.

Abstract
Anthracyclines used in the treatment of acute myelogenous leukemia (AML) inhibit the activity of the mammalian topoisomerase II (topo II) isoforms, topo II α and topo IIβ. In 230 patients with non-M3 AML who received frontline ara-C/daunorubicin we determined expression of topo IIα and topo IIβ by RT-PCR and its relationship to immunophenotype (IP) and outcomes. Treatment outcomes were analyzed by logistic or Cox regression. In 211 patients, available for analysis, topo IIα expression was significantly lower than topo IIβ (P < 0.0001). In contrast to topo IIα, topo IIβ was significantly associated with blast percentage in marrow or blood (P = 0.0001), CD7 (P = 0.01), CD14 (P < 0.0001) and CD54 (P < 0.0001). Event free survival was worse for CD56-negative compared to CD56-high (HR = 1.9, 95% CI [1.0-3.5], p = 0.04), and overall survival was worse for CD-15 low as compared to CD15-high (HR = 2.2, 95% CI [1.1-4.2], p = 0.02). Ingenuity pathway analysis indicated topo IIβ and immunophenotype markers in a network associated with cell-to-cell signaling, hematological system development/function and inflammatory response. Topo IIβ expression reflects disease biology of highly proliferative disease and distinct IP but does not appear to be an independent variable influencing outcome in adult AML patients treated with anthracycline-based therapy.

Abstract
Introduction: Topoisomerase II inhibitors have long been used in the frontline and as salvage therapy for AML, with daunorubicin and idarubicin being prototypical agents in this therapeutic class, classically in combination with nucleoside analogs, e.g. cytarabine. Most recently, several other compounds from this drug class have or are being investigated. Areas covered: The current paper reviews older and newer topoisomerase II inhibitors in clinical development for the treatment of AML. The authors discuss the clinical use of these agents, current trials involving them as well as their safety profile. Important side effects of these medications including therapy-related AML (t-AML) are also covered. Expert opinion: Topoisomerase II inhibitors have helped improve outcomes in AML. Recently, the FDA approved several agents including CPX-351 for the treatment of secondary and t-AML. CPX-351 may have applicability in other high-risk myeloid diseases. Future directions include a combination of these agents with other targeted therapies. Finally, the authors believe that small molecule inhibitors, such as venetoclax and possibly immunotherapy options could also be incorporated to our treatment paradigm in selected patients.

Abstract
FLT3 mutations occur in up to a third of newly diagnosed patients with acute myeloid leukemia (AML) and confer poor prognosis. Clinical development of FLT3 tyrosine kinase inhibitors for AML initially involved broad-spectrum inhibitors (midostaurin, sorafenib) targeting multiple kinases. Addition of midostaurin to upfront intensive chemotherapy for younger patients with FLT3 mutant AML significantly improved overall survival and validated FLT3 as a therapeutic target. Other regimens such as sorafenib and hypomethylating agents (azacitidine, decitabine) have expanded the use of FLT3 inhibitors to other populations with FLT3 mutant AML. However, emerging data on new highly potent and specific FLT3 inhibitors such as quizartinib, gilteritinib, and crenolanib suggest that these agents may soon supplant midostaurin and sorafenib in the upfront setting. Using case presentations, this review provides guidelines and practical management strategies for frontline therapy of patients with newly diagnosed FLT3 mutant AML in the current era.

Abstract
Importance Only 3.4% of cancer drugs evaluated in phase 1 trials are approved by the US Food and Drug Administration, with most failing in phase 3 trials. Objective To investigate whether an association exists between the sponsorship and conduct of a negative phase 3 randomized clinical trial (RCT) investigating a cancer drug that lacked supporting phase 2 trial evidence for that drug, and to evaluate the association with overall survival among patients randomized to the experimental arm of such phase 3 trials. Data Sources Articles in the Lancet, Lancet Oncology, JAMA, JAMA Oncology, and Journal of Clinical Oncology published between January 2016 and June 2018 were searched. Study Selection Phase 3 RCTs of cancer drugs that failed to improve the primary end point were selected and any prior phase 2 trial of the same drug that supported the phase 3 trial was selected without any date or journal restrictions. Data Extraction and Synthesis Percentages of negative phase 3 RCTs of cancer drugs that lacked any phase 2 evidence, had a negative phase 2 trial, or had a positive phase 2 study were extracted. Associations were assessed using the Fisher exact test. Pooled hazard ratios and 95% CIs for the overall survival of patients enrolled in these negative phase 3 RCTs were estimated using a random-effects model. Main Outcomes and Measures Negative phase 3 RCTs with a lack of a phase 2 trial or the presence of a negative phase 2 trial and overall survival of enrolled patients in the phase 3 RCTs. Results In this meta-epidemiological study, 67 negative phase 3 RCTs on cancer drugs, which included 64 600 patients, met the criteria of being sponsored by industry or academic groups, of which 42 RCTs (63%) were industry sponsored and the remaining 25 RCTs (37%) were academic. A phase 2 trial was not available for 28 of these trials (42%). Of 29 trials (43%) with a phase 2 trial available, 8 trials (28%) failed to meet their primary end points and 5 of those were industry sponsored. There was no association with overall survival for patients participating in these negative phase 3 RCTs (pooled hazard ratio, 0.99; 95% CI, 0.96-1.02). When the pooled analysis was limited to the 27 RCTs with a hazard ratio above 1.00, the overall pooled hazard ratio for overall survival was 1.11 (95% CI, 1.06-1.16). No association between having a negative or undefined phase 2 trial and trial sponsorship was found using the Fisher exact test. Conclusions and Relevance More than 40% of the negative phase 3 RCTs in oncology published in these 5 journals were conducted without a supporting phase 2 trial and were sponsored by both academia and industry. Running such trials not only may risk loss of resources owing to a failed trial but also may be associated with decreased patient survival. Further research and regulations in this area appear warranted.

In the treatment of acute myeloid leukemia (AML), the "7 + 3"-based strategy, combining cytarabine 100-200 mg/m2 for 7 days with an anthracycline for 3 days, remains the standard of care for younger and medically fit patients. Daunorubicin (DNR) and idarubicin (IDA) are the two anthracyclines most commonly used. DNR and IDA are used interchangeably with different conversion factors, as there is no high-level evidence on the equipotency of these two agents for AML treatment. To determine the equipotent doses of DNR and IDA, we first systematically reviewed studies directly comparing the clinical outcomes of AML induction therapy utilizing DNR and IDA. We found 15 articles that met our inclusion criteria and compared time-to-event survival end points as well as complete remission rates post-induction. The DNR:IDA equipotency ratio was estimated at 5.90 with 95% confidence interval (CI) 1.7-20.7. To validate the estimate from our meta-analysis biologically, we conducted in vitro tests comparing anti-AML activity of DNR and IDA against six AML cell lines and two primary AML cells from patients with different cytogenetic and molecular characteristics. Based on these in vitro data, the equipotency dose ratio between DNR and IDA was 4.06 with 95% CI 3.64-4.49. Combining the estimates from the meta-analysis and the in vitro data using inverse-variance weighting, the current best estimate of the DNR:IDA equipotent ratio is 4.1 with 95% CI 3.9-4.3. This estimate, however, is largely driven by the in vitro chemo-sensitivity data. Given clinical studies demonstrating the safety of IDA at higher doses, our work implies that dose intensification of IDA could be investigated in future clinical trials in AML.

Abstract
Background Induction schedules in acute myeloid leukemia (AML) are based on combinations of cytarabine and anthracyclines. The choice of the anthracycline employed has been widely studied in multiple clinical trials showing similar complete remission rates. Materials and Methods Using an ex vivo test we have analyzed if a subset of AML patients may respond differently to cytarabine combined with idarubicin, daunorubicin or mitoxantrone. Bone marrow (BM) samples of 198 AML patients were incubated for 48 hours in 96 well plates, each well containing different drugs or drug combinations at different concentrations. Ex vivo drug sensitivity analysis was made using the PharmaFlow platform maintaining the BM microenvironment. Drug response was evaluated as depletion of AML blast cells in each well after incubation. Annexin V-FITC was used to quantify the ability of the drugs to induce apoptosis, and pharmacological responses were calculated using pharmacokinetic population models. Results Similar dose-respond graphs were generated for the three anthracyclines, with a slight decrease in EC50 with idarubicin (p=1.462E-06), whereas the interpatient variability of either drug was large. To identify those cases of selective sensitivity to anthracyclines, potency was compared, in terms of area under the curve. Differences in anthracycline monotherapy potency greater than 30% from 3 pairwise comparisons were identified in 28.3% of samples. Furthermore, different sensitivity was detected in 8.2% of patients comparing combinations of cytarabine and anthracyclines. Discussion A third of the patients could benefit from the use of this test in the first line induction therapy selection, although it should be confirmed in a clinical trial specifically designed.

Abstract
INTRODUCTION Induction chemotherapy based on anthracyclines and cytarabine (Ara-C) combination remains the standard of care for acute myeloid leukemia (AML) patients who are considered candidate for intensive and curative approaches. However, the toxicity of this regimen is high, with disappointing clinical outcomes among the so-called poor-prognosis AML subsets, which generally refer to patients with adverse cytogenetic risk, secondary AML including therapy-related AML, poor-prognosis mutations, especially FLT3-ITD, and relapse/refractory AML. Areas covered: To the best of our knowledge, the role and efficacy of 7 + 3 schedules containing daunorubicin (DNR) and Ara-C for certain types of poor-prognosis AML has not been systematically assessed. A critical approach to the role of DNR and Ara-C induction could be relevant to establish which patients should be enrolled in clinical trials using novel therapies. Expert commentary: In this regard, a recent randomized clinical trial (RCT) showed improved results in older patients with sAML or high-risk cytogenetics who received CPX-351 compared with standard 7 + 3 combination. We perform a systematic literature review to analyze the clinical outcomes reported with DNR plus Ara-C regimens in adult patients with poor-prognosis AML, the use of liposomal formulations of DNR and Ara-C and the RCTs which compared standard 7 + 3 with the addition of a third drug.

Abstract
Given the recent approvals of new agents for acute myeloid leukemia (AML), a clinical trial pipeline stocked with novel therapies, and the rapid integration of imaginative approaches in diseases like acute lymphocytic leukemia and chronic lymphocytic leukemia, it is reasonable to ask whether treatment of AML might finally depart from the classical cytotoxic induction therapy that has been employed since the 1970s. However, for better or worse, in 2018, cytotoxic induction regimens remain the standard of care for most patients. Indeed, the future likely lies in combinations of therapies that act with a spectrum of mechanisms. Using a case-based format, this review will outline current treatment expectations for patients according to karyotypic risk and familiarize readers with the basis for common induction choices. Relapsed/refractory disease may be especially amenable to interventions with novel agents or clinical trials; however, there are still some patients who most benefit from intensive chemotherapy. This review will outline risk systems that help the practitioner identify those with the best chances for response and survival. Finally, clinical tools, including geriatric assessments and comorbidity calculators, may help clinicians recognize patients for whom disease risk and comorbidity tip the balance against classical chemotherapy, a frequent challenge for those who treat this devastating disease.

Abstract
BACKGROUND The 2 main formulations of anthracycline used for acute myeloid leukemia (AML) induction therapy are idarubicin (IDA) and daunorubicin. PATIENTS AND METHODS The present systematic review and meta-analysis compared the efficacy and toxicity between IDA and high-dose daunorubicin (HDD) for induction therapy for adult AML. Relevant studies reported before June 2018 were searched from the Medline and Embase databases. RESULTS A total of 5 studies with 1809 participants (3 randomized controlled studies and 2 retrospective cohort studies) met the eligibility criteria and were included in the meta-analysis. The patients in the IDA arm for induction therapy had a significantly greater complete response rate after the first course of induction therapy compared with those in the HDD arm (66.7% vs. 61.1%, respectively; odds ratio, 1.23; P = .04; I2 = 0%). A significantly lower rate of refractory AML was also observed in the IDA group than in the HDD group (16.8% vs. 20.7%, respectively; odds ratio, 0.77; P = .04; I2 = 0%). However, no difference was found in the long-term overall survival between the 2 groups. Also, the induction mortality rate, febrile neutropenia rate, and cardiotoxicity rate were not significantly different between the 2 groups. The major limitation was the relatively small number of included studies, which could have limited the power of the meta-analysis to demonstrate significant long-term benefits. CONCLUSION The complete response rate after the first course of induction therapy was significantly greater among adult patients with AML who had received IDA as part of induction therapy compared with those who had received HDD.

Abstract
BACKGROUND Acute respiratory failure is a leading cause of intensive care unit admission in patients with hematological malignancies; it carries a mortality rate exceeding 50%. Venovenous extracorporeal membrane oxygenation use in patients with acute hematologic malignancies concurrently receiving induction chemotherapy is not well studied. CASE PRESENTATION A 44-year-old male developed acute respiratory distress syndrome in the setting of newly diagnosed acute myelogenous leukemia. He underwent successful induction chemotherapy while on venovenous extracorporeal membrane oxygenation. His course was complicated by a devastating subarachnoid hemorrhage. Life support modalities were discontinued in accordance to the wishes of the family. CONCLUSION There is a lack of data to guide use of induction chemotherapy in patients with acute hematologic malignancies requiring venovenous extracorporeal membrane oxygenation, particularly with regard to dosing, safety, and efficacy of chemotherapeutic agents. This case highlights a potential role of venovenous extracorporeal membrane oxygenation in select young acute myelogenous leukemia patients who might benefit from this intervention and warrants further research.

Abstract
Adolescents and young adults (AYAs) form a unique group of patients with newly diagnosed acute myeloid leukemia (AML). They differ in terms of disease biology, psychosocial challenges, survival, and in other important respects from children as well as from middle-aged and older adults. AYAs may be treated using pediatric protocols developed in trials composed primarily of younger patients, or using adult protocols developed in trials composed primarily of older patients. After reviewing the distinguishing characteristics of AYAs with AML, we compare and contrast the chemotherapy approaches and argue that neither the pediatric nor adult approaches may be ideally suited for AYAs and the development of AYA-specific approaches merits further consideration. We finish by putting forth ideas for future research to optimize chemotherapy treatment of AYAs with AML.

Abstract
Outcomes with “7+3” are often unsatisfactory in acute myeloid leukemia (AML). Trials demonstrating improved outcomes with high-dose cytarabine, addition of cladribine, or escalated anthracycline doses prompted a phase 1/2 study (NCT02044796) of G-CSF, cladribine, high-dose cytarabine, and dose-escalated mitoxantrone (GCLAM) in adults with newly-diagnosed AML or other high-grade myeloid neoplasms. 121 patients, median age 60 (range: 21–81) years, were enrolled. In phase 1, cohorts of 6–12 patients were assigned to 12–18mg/m2/day of mitoxantrone as part of GCLAM. Because all dose levels were well-tolerated, mitoxantrone at 18mg/m2 was declared the recommended phase 2 dose (RP2D). 74/94 (79%) patients treated at the RP2D achieved a complete remission (CR; 67/74 without measureable residual disease [MRD]) for an overall MRDneg CR rate of 71% (primary phase 2 endpoint). Seven patients achieved a CR with incomplete blood count recovery (CRi; 7%, 5 MRDneg) for a CR/CRi rate of 81/94 (86%). 4-week mortality was 2%. After adjustment, the MRDneg CR and CR/CRi rates compared favorably to 100 matched controls treated with 7+3 at our center and 245 matched patients treated with 7+3 on a cooperative group trial. Our data indicate GCLAM with mitoxantrone at 18mg/m2/day is safe and induces high-quality remissions in adults with newly-diagnosed AML.

Abstract
While the past decade has seen a revolution in understanding of the genetic and molecular etiology of the disease, in clinical practice, initial therapy for acute myeloid leukemia (AML) patients has been a relatively straightforward choice between intensive combination cytotoxic induction therapy as used for decades or less-intensive hypomethylating therapy. The year 2017, however, witnessed US Food and Drug Administration approvals of midostaurin, enasidenib, gemtuzumab ozogamicin and CPX-351 for AML patients, with many other promising agents currently in clinical trials. This review discusses these options, highlights unanswered questions regarding optimal combinations and proposes some suggested approaches for the personalization of initial therapy for AML patients.

Abstract
Acute myeloid leukemia (AML), a clonal hematologic malignancy that results in bone marrow failure, is the most common acute leukemia in adults (median age of diagnosis 67 yrs), and treatment options, especially in the elderly population, are limited. Induction chemotherapy with 7 + 3, the combination of continuous-infusion cytarabine and intermittent dosing of an anthracycline administered over 7 and 3 days, respectively, has remained the standard of care since its introduction in 1973 in the United States. Midostaurin is a first-generation FMS-like tyrosine kinase 3 (FLT3) inhibitor (TKI) that was approved by the U.S. Food and Drug Administration in April 2017 for the treatment of FLT3-mutant AML. We performed a search of the PubMed database (January 1990-January 2017) to review pertinent clinical trials of midostaurin. Phase I, II, and III trials reported in English evaluating the safety and efficacy of midostaurin in patients with AML or myelodysplastic syndrome were included. The ClinicalTrials.gov database was also searched for ongoing trials. In the only phase III trial that has been conducted to date, midostaurin demonstrated significant improvement compared with placebo in overall and event-free survival in patients aged 18-59 years with newly diagnosed FLT3-mutant AML treated with standard induction chemotherapy. The median overall survival for patients randomized to the midostaurin group was 74.7 months versus 25.6 months in the placebo group (hazard ratio [HR] 0.78, 95% confidence interval [CI] 0.63-0.96, p=0.009). Median event-free survival was 8.2 months with midostaurin compared with 3.0 months with placebo (HR 0.78, 95% CI 0.66-0.93, p=0.002). In addition to being evaluated in combination with conventional chemotherapy, midostaurin has been studied as monotherapy, in combination with the hypomethylating agents azacitidine and decitabine, and as single-agent maintenance. Studies evaluating midostaurin in the maintenance setting after allogeneic stem cell transplantation are underway. Midostaurin is the first oral multitargeted TKI to improve overall survival in patients with FLT3-mutant AML and represents an important addition to the limited armamentarium against AML.
