Minimal Residual Disease (MRD) Monitoring in NPM1 Mutated Acute Myeloid Leukemia (AML): Impact of Concurrent FLT3-ITD and DNMT3A Mutations on MRD Kin…
2013
Abstract Introduction In a recent update on MRD monitoring in 407 NPM1 mutated (NPM1mut) AML patients (pts) we could confirm the results from our previous study showing that achievement of RQ-PCR negativity after double induction (DI), after completion of therapy (CT) as well as during the follow-up period (FUP) is significantly associated with a lower cumulative incidence of relapse (CIR) and superior overall survival (OS) [Döhner K, Annals of Hematol; 2013;Suppl.1,92:S39]. In addition, in pts with concurrent FLT3-ITD (FLT3-ITDmut) or DNMT3A (DNMT3Amut) mutations, we also showed that the median NPM1mut transcript levels after each treatment cycle were significantly higher. Aim To evaluate …
High BCR-ABL Levels At Diagnosis Are Associated with Unfavorable Responses to Imatinib Mesylate.
2012
Abstract Abstract 2790 The approval of second-generation tyrosine kinase inhibitors (TKIs) for the first line treatment of Chronic Myeloid Leukemia (CML) has generated a need for early molecular parameters associated with inadequate responses to Imatinib Mesylate (IM). Recent evidence suggests that CML patients presenting BCR-ABL/ABLIS levels >10% after 3 months of IM or >1% after 6 months of treatment have inferior outcomes in terms of both overall survival (OS) and progression-free survival. We wanted to establish if high BCR-ABL transcripts at diagnosis would also be associated with unfavorable responses to IM. To this end, we correlated quantitative determinations of BCR-ABL measu…
High BCR-ABL/GUSIS Levels At Diagnosis Are Associated With Unfavorable Responses To Imatinib
2013
Abstract The approval of three tyrosine kinase inhibitors (TKIs) for the first line treatment of Chronic Myeloid Leukemia (CML) has generated an urgent need for molecular parameters predictive of unfavorable therapeutic outcomes. Recent evidence suggests that failure to achieve early molecular responses (i.e. BCR-ABL/ABLIS levels <10% after 3 months or <1% after 6 months of TKI treatment) results in inferior rates of both overall and progression-free survival. With the current study, we wanted to establish if high BCR-ABL transcripts at diagnosis would be associated with unfavorable responses to Imatinib Mesylate (IM). Thus, we correlated quantitative determinations of BCR-ABL levels …
A systematic review and meta-analysis of the impact of WT1 polymorphism rs16754 in the effectiveness of standard chemotherapy in patients with acute …
2015
The polymorphism rs16754 of the WT1 gene has been described as a possible prognostic marker in different acute myeloid leukemia (AML) cohorts; however, it is not supported by all the studies. We performed the first meta-analysis evaluating the effect of this polymorphism upon the effectiveness of standard AML therapy. Fourteen cohort studies were included (3618 patients). Patients with the variant allele showed a significant higher overall survival (OS) at 5 years (OR: 1.24, 95% CI: 1.06-1.45, P = 0.007, with dominant model). WT1 did not influence complete remission, but a higher disease-free survival was observed with the variant allele. In the subgroup analysis, Caucasians, pediatric and …
Early diagnosis, clinical management, and follow-up of cardiovascular events with ponatinib
2020
Chronic myeloid leukemia (CML) is a myeloproliferative disorder characterized by neoplastic transformation of pluripotent cells due to a typical cytogenetic and molecular mutation known as Philadelphia (Ph) chromosome. In 2001, the introduction of the tyrosine kinasis inhibitor (TKI) imatinib as a therapeutic strategy for CML with PH chromosome mutation represented an important step towards treatment of these patients, and nowadays, this drug represents the gold therapeutic standard in this clinical setting. A second generation of TKIs (dasatinib, nilotinib, and bosutinib) showed an effective action in all patients with mutations resistant to imatinib. Ponatinib is a third-generation TKI an…
First Interim Analysis of the Italian Dante Study: De-Escalation before Treatment-Free Remission in Patients with Chronic Myeloid Leukemia Treated wi…
2021
Abstract Introduction: Treatment-free remission (TFR) in chronic myeloid leukemia (CML) is demonstrated to be achievable and recommended for patients (pts) in sustained deep molecular response (sDMR) who can discontinue tyrosine kinase inhibitor (TKI) treatment and maintain responses in ~50% of cases. While the feasibility and safety of TKI cessation have been largely demonstrated, the strategies of TFR optimization are yet to be clarified. Studies (eg. DESTINY) investigating de-escalation, mainly after imatinib, suggested that a stepwise approach may favor TFR outcome. We present the interim results of the phase 2, prospective, multicenter DANTE study (NCT03874858) evaluating de-escalation…
Pevonedistat (PEV) + Azacitidine (AZA) Versus AZA Alone As First-Line Treatment for Patients with Higher-Risk Myelodysplastic Syndromes (MDS)/Chronic…
2021
Abstract Background: Older patients with higher-risk MDS/CMML or AML with 20-30% marrow blasts typically receive single-agent hypomethylating agent (HMA) therapy. Median response duration and survival for these patients is poor, and many patients with MDS transform to secondary AML, which is associated with a particularly dismal prognosis. Novel HMA-based combination therapies that improve survival, delay transformation to AML, and increase depth and duration of response vs single-agent HMA therapy without additional toxicity or myelosuppression are needed. In a randomized, proof-of-concept phase 2 study PEV - a first-in-class, selective inhibitor of NEDD8-activating enzyme - in combination…
BCR-ABL Derived Peptide Vaccine in Chronic Myeloid Leukemia Patients with Molecular Minimal Residual Disease During Imatinib: Interim Analysis of a P…
2009
Abstract Abstract 648 Introduction: Imatinib (IM) 400mg daily is the standard treatment for chronic myeloid leukemia (CML) patients and a complete cytogenetic response (CCyR) is achieved in the majority of patients within one year of treatment. In addition, a considerable number of patients reach a major molecular response (i.e BCR-ABL/ABL ratio <0.1%) but BCR-ABL transcript is still measurable in most of treated patients revealing the persistence of a minimal residual disease (MRD). In a previous small pilot study, vaccinations with p210 b3a2-derived fusion peptides in IM treated CML patients appeared to induce both a peptide specific immune response and a reduction of residual disease …
Related versus unrelated donor transplantation for high risk (HiRi) acute myeloid leukemia (AML) in first complete remission (CR1)
2007
Abstract Allogeneic hematopoietic stem cell transplantation (allo-SCT) from an HLA-identical sibling donor (SIB) is considered the preferred postremission therapy for younger patients with HiRi AML in CR1. The role of allo-SCT from volunteer unrelated donors (VUDs) is less clear and randomized controlled trials addressing this issue do not exist. We performed an observational landmark analysis on parallel cohorts of patients aged &lt;60 years with AML in CR1 and HiRi cytogenetics who had been enrolled into the AML Cooperative Group (AMLCG) 1999 trial. 2347 patients were evaluable for the present update. 243/2347 patients were &lt;60 years of age and had unfavorable cytogenetics [com…
Mutational Profiling Predicts Clinical Outcomes to Azacytidine and Low Dose Cytarabine Plus Fludarabine (FLUGA) in Elderly Acute Myeloid Leukemia Pat…
2019
BACKGROUND: Older patients with acute myeloid leukaemia (AML) who are unsuitable for standard induction therapy have limited treatment options. While DNMT3A, TET2, IDH1/2 and TP53 mutations have been previously associated to better response to hypomethylating agents, there are no molecular biomarkers for low-dose cytarabine (LDAC)-based regimens. AIMS: To predict outcome in AML older patients at diagnosis based on mutation status in the context of FLUGAZA trial. FLUGAZA trial was focus on >65 years AML de novo patients comparing azacytidine vs. fludarabine and LDAC (FLUGA Scheme). METHODS: We analyzed bone marrow (BM) samples at diagnosis from 209 out of 285 AML patients treated accordin…
