ICS+LTRA compared with ICS Summary of findings 226, 227 118, 197, 228-231 We found two systematic reviews with meta-analyses and five RCTs meeting our inclusion/exclusion criteria (Table 21). Most studies were conducted in adolescent and adult 231 populations; one study enrolled a pediatric population ages six to 14 and one enrolled children 197 and adolescents (6 to 17 years of age). Overall, the addition of LTRAs to ICSs compared to continuing the same dose of ICSs resulted in improvement in rescue medicine use and a non-statistically significant trend toward fewer exacerbations requiring systemic steroids. There were some conflicting results and further research may alter the results (Evidence Tables A and B). Detailed Assessment Description of Studies 226, 227 118, 197, 228-231 We found two systematic reviews with meta-analyses and five RCTs meeting our inclusion/exclusion criteria (Table 21). Three compared budesonide plus montelukast with 118, 230 budesonide alone. Two studies compared the combination of an ICS plus LTRA with the 197, 228, 229, 231 same dose ICS and three studies compared the combination with an increased dose of ICS. Study Populations The five RCTs included a total of 2,423 patients. Most studies were conducted in adolescent and 231 adult populations; one study enrolled a pediatric population ages six to 14 and one enrolled 197 children and adolescents (6 to 17 years of age). One was conducted in the United States, one in Europe, one in India, and two were other multinational combinations. Asthma severity ranged from mild persistent to severe persistent. Two enrolled patients with mild to moderate persistent asthma; two enrolled patients with mild to severe persistent asthma; one enrolled patients with moderate persistent asthma. Methodologic Quality The five included RCTs were fair quality studies.

The availability of genetic the B1 sheet of the tyrosine kinase domain (TKD) 1 that is present in testing for minimal residual disease has become another clinically 1/4 of the cases, has been shown to be associated with very relevant tool with which to identify patients with NPM1-mutated poor prognosis. Gale et al reported a better outcome in FLT3-ITD- FLT3-ITD mutation. FLT3-ITDs are found in 20% of all AML positive patients harboring a concurrent NPM1 mutation,24 (CN-AML: 28%–34%) and have been associated with inferior whereas others showed that the “protective effect” of NPM1 in outcome. Incidence of intermediate-risk AML associated gene younger AML patients have suggested that the unfavorable effect of mutations by age group. Age groups shown are: 45 years, 45–60 DNMT3A mutations could be overcome by increasing the dose of years, 60–75 years, and 75 years. Approximately 15%–20% of all erably increases with age ( 60 years: 7%–10%; 60 years: AML cases and 25%–30% of CN-AML cases carry either IDH1 or 44 30 19%–25%). Two studies have reported that TET2 mutations are IDH2 mutations. IDH mutations in AML cluster to distinct unfavorable in terms of survival in CN-AML or in AML with codons, namely IDH1 codon R132 and IDH2 codons R140 or 30 intermediate-risk cytogenetics, but neither of these studies found R172. Several studies assessing the prognostic relevance of IDH1 TET2 mutations to be an independent prognostic factor after and IDH2 mutations in CN-AML have yielded conflicting results. A CALGB study by Metzeler et al some, but not other, studies, IDH1 and/or IDH2 mutations reported TET2 mutations as an adverse factor for CR achieve- were revealed as an unfavorable prognostic factor in the subset of mutant negative ment, event-free survival, and disease-free survival only among CN-AML cases with the genotype NPM1 /FLT3-ITD. CN-AML defined as favorable risk according to the ELN Conversely, one study in AML with intermediate-risk cytogenetics 41 43 recommendations. In contrast, in our study, we could not found IDH1 and IDH2 mutations to be a favorable factor for 11 show a prognostic effect of TET2 mutations in either CN-AML outcome, resulting in a 3-year OS above 80% in this genotype. Thus far, there is no sufficient Further subset analyses in this study revealed that the favorable effect evidence for TET2 mutations as a clinically relevant prognostic of IDH2 mutations was found exclusively in patients with IDH2 R140 marker in AML or in subsets of AML and a more comprehensive mutations; IDH2 R172-mutated alleles only rarely co-occured with 11 evaluation, in particular within the context of other potentially NPM1 mutations. Therefore, the improved prognosis in IDH2/NPM1- 43 modulating genetic lesions, is necessary. Beyond involvement in recurrent chromo- less well established is the prognostic impact of IDH2 R172 in somal rearrangements, intragenic mutations of RUNX1 have been intermediate-risk and/or CN-AML. There is some evidence from a 45-48 found in 5%-15% of AML cases. There is a significant Cancer and Leukemia Group B (CALGB) study in CN-AML that these increase of the mutation frequency with older age that is paralleled mutations might be associated with inferior induction success in this 31 by an association of the mutation with secondary AML evolving cytogenetic subset of AML patients. In all studies, RUNX1 mutations have consistently been associated with resis- ASXL1 mutation. ASXL1 mutations are found in 5%–11% of 37-40 tance to standard induction therapy and with inferior survival. The studies on 45 48 the studies by Tang et al and Mendler et al, RUNX1 mutations ASXL1 mutations in AML are remarkably consistent with respect to 37-40 were revealed as a strong independent predictor for inferior OS. An intriguing finding is the frequent frequency in patients 60 years of age compared with those 60 38 co-occurrence with mutations in genes encoding epigenetic years of age (16. In intermediate-risk modifiers such as ASXL1 (21%), MLL (alias KMT2A; lysine AML and/or in the subset of CN-AML patients, ASXL1 mutations (K)-specific methyltransferase 2A) partial tandem duplication constitute an adverse prognostic factor for long-term outcome, with (17%), IDH2 (15%), and BCOR (BCL6 corepressor; 8%). The low complete remission (CR) rates found in all studies. In patients eligible for intensive induction TET2 mutation. TET2 mutations are enriched in the subset of therapy, 3 days of an anthracycline (daunorubicin, 60 mg/m2, CN-AML patients, in whom their frequency ranges between 9% idarubicin, 10-12 mg/m2, or the anthracenedione mitoxantrone, Hematology 2014 37 10-12 mg/m2) and 7 days of cytarabine (100-200 mg/m2 continu- risk group.

As a general theme, lower doses of now considered to be the “favorable” subgroup, do not appear to anthracyclines (eg, daunorubicin 45 mg/m2 for 3 days) are no longer benefit from allogeneic HSCT in CR114; conversely, there are considered appropriate in either younger or older patients (at least markers, such as FLT3-ITD (Richard F.
