reported post‐treatment clearance of mutations might help stratify MFC negative patients according to risk of relapse.100.
The pathophysiology of the disease associates with cytogenetic abnormalities, gene mutations and aberrant gene expressions. These and other questions can only be answered in clinical trials and given the unsatisfactory outcomes of even patients at low risk of TRM in the ELN intermediate group (<50% long term survival) a case can be made that the first option even in such patients should be a clinical trial. MRD testing lacks standardization (although the same can be said of morphologic evaluation). reporting a rate of 100% in 21 patients with TP53 mutations, who received 20 mg/m2 daily × 10 days has received much attention.82 The CR rate was 19%, the remainder of the response being varying forms of CRi with <5% marrow blasts by morphology.
SeriesEditorInformation azacytidine vs CCR trial noted above enrolled relatively few patients in the 7 + 3 vs azacytidine arm.13 An ongoing EORTC trial (NCT02172872, “inDACtion”) is randomizing patients aged ≥60 years with PS 0‐2 and normal kidney/liver function between standard 7 + 3 induction and 10‐day decitabine followed by allogeneic HCT in responding patients; estimated completion date is December, 2019. Testa U, Riccioni R, Diverio D, Rossini A, Lo Coco F, Peschle C. Interleukin-3 receptor in acute leukemia. Sixty‐day mortality was 21% with 7 + 3 and 13% with CPX and toxicity was similar.75 About 34% of CPX and 25% of 7 + 3 patients received HCT; the transplanted CPX patients were older but more often in CR than the transplanted 7 + 3 patients. [1,2] In this issue of ONCOLOGY, Drs. Genes Chromosomes Cancer. have suggested persistence of MFC‐detected MRD after 3 months in CR or CRi is associated with relapse after therapy with azacitidine or decitabine in a population whose median age was 75 years (Supporting Information Figure 4).101 Nonetheless, while it is clear detection of MRD provides invaluable information, at least after intensive therapy ± HCT, addition of MFC status at time of CR to pretreatment variables had only modest quantitative effect on assessing chance of relapse,102 suggesting the likely need to consider changes in MRD over time rather than MRD at only a single instance, to develop new means for MRD detection for example, “duplex sequencing”103 or analysis of leukemia “stem cells”104 and to use these methods in complementary fashion. Thus, studies are needed to determine if examining a more homogenous population of malignant cells may improve the precision of risk stratification guidelines, and these studies, including those examining the current ELN-2017 guidelines, need to be extended to older patients [5, 9,10,11,12].
found 25% had been treated at a National Cancer Institute designated Cancer Center (NCI‐CC, defined as a center which treated a median of 13 AML patients annually) and 75% at a non‐NCI‐CC that treated at least one person with AML annually (median 2). Regarding 7 + 3 vs more intensive therapy, a German randomized comparison involving 3375 adults found equivalent EFS and RFS with 7 + 3 and high‐dose cytarabine‐containing therapy.47 More recently, Garcia‐Manero et al. stPart The included patients were assigned into two cohorts by simple randomization: a discovery cohort (n = 190) and a validation cohort (n = 193) by the SWOG Statistical Center [32]. internal EBioMedicine.

Favorable ELN-2017 risk was also significantly associated with improved OS in VLBs (MNCs, HR = 0.58, P = 0.060 and VLBs, HR = 0.38, P = 0.001, Table 2).

Persistence of non‐ARCH, but not ARCH, mutations were associated with higher cumulative incidence of relapse and shorter survival and relapse‐free survival.

A portion of unsorted MNCs was lysed, while the remainder of the sample underwent fluorescence-activated cell sorting (FACS) to isolate VLBs using forward-by-side scatter, DAPI staining and fluorescently-labeled antibodies to CD45, CD34 and CD117 as previously described [6].

Although used to treat AML for many years, decitabine has typically been given for 5 days at a daily dose of 20 mg/m2.
