Next-generation sequencing reveals relapse and leukemia-free survival risks in newly diagnosed acute myeloid leukemia treated with CAG regimen combined with decitabine

Background:Acute myeloid leukemia(AML)is a heterogeneous hematopoietic malignancy whose prognosis is associated with several biomarkers.Decitabine,a deoxyribonucleic acid(DNA)methyltransferase(DNMT)in-hibitor,combined with cytarabine,aclarubicin hydrochloride,and granulocyte colony-stimulating factor(DCAG),has been used in patients newly diagnosed with AML.This regimen has been especially used in older and fragile patients who are immunocompromised or have co-morbidities,as well as those with specific gene mutations.However,the integration of molecular risk stratification and treatment guidance for the DCAG regimen has not been well defined.Therefore,this study aimed to investigate the genetic mutations associated with AML and establish appropriate treatment strategies for patients newly diagnosed with AML.Methods:This study analyzed the clinical data and genetic mutations based on next-generation sequencing(NGS)in 124 newly diagnosed patients with AML who received the DCAG regimen at the People's Liberation Army(PLA)General Hospital from January 2008 to August 2020.Factors associated with the cumulative incidence of relapse(CIR)and leukemia-free survival(LFS)in patients newly diagnosed with AML were analyzed.Results:The most adverse prognosis of DCAG-treated patients was observed in those with FLT3-ITD,KIT,PTPN11,GATA2,or IDH1 mutations during univariable analysis,whereas PTPN11 mutation was solely significant in multivariable analysis,with an increased likelihood of CIR(P=0.001)and reduced LFS duration(P=0.077).Hyperleukocytosis was maintained as an independent risk factor for increased CIR risk(P=0.044)and decreased LFS duration(P=0.042)in multivariable analysis.In this study,we validated the risk classification of patients with AML receiving an epigenetic modifier-based induction regimen across a broad age range.Conclusion:NGS demonstrated a dismal overall outcome in patients with the rare PTPN11 mutations,indicating the need for new therapies that target this high-risk subtype of AML.These results offer a potential molecular stratification and treatment guidance for patients with AML.

Next-generation sequencing revealed factors associated with cumulative incidence of relapse and leukemia-free survival in patients with newly diagnosed acute myeloid leukemia

BackgroundSeveral prognostic biomarkers have been validated for acute myeloid leukemia(AML),a heterogeneous hematopoietic malignancy.However,the factors associated with the cumulative incidence of relapse(CIR)and leukemia-free survival(LFS)in real-world patients with AML have not been well defined.MethodsThis study examined clinical and mutational data of 246 patients with newly diagnosed AML who received the traditional“3+7”regimen in PLA General Hospital from January 2008 to August 2020.Factors associated with CIR and LFS in patients newly diagnosed with AML were analyzed using next-generation sequencing.ResultsAdditional sex combs-like 1(ASXL1)and Serine/arginine-rich splicing factor 2(SRSF2)mutations were found to be associated with an increased risk of CIR and a reduced LFS in univariate analysis,while only SRSF2 mutations were associated with these factors in the multivariate analysis.Hyperleukocytosis maintained an independent effect on LFS in the multivariate analysis.Hematopoietic stem cell transplantation conferred a significant prognostic benefit on both CIR and LFS in our cohort.Furthermore,we validated the risk classification of patients with AML receiving traditional induction regimens across a broad age range.Based on next-generation sequencing results,we concluded that SRSF2 mutations were predictive of an increased risk of relapse,inferior LFS rates,and non-relapse mortality in patients with newly diagnosed AML.ConclusionThese findings indicate that patients with SRSF2 mutations might not benefit from the conventional“3+7”regimen.Our results may help in developing molecular stratification strategies and could guide treatment decisions for patients with newly diagnosed AML.
