Monitoring of Minimal Residual Disease (MRD) of DNMT3A Mutations (DNMT3Amut) in Acute Myeloid Leukemia (AML): A Study of the AML Study Group (AMLSG)
2015
![Graphic][1] Background : The DNA methyltransferase 3A ( DNMT3A) is one of the most frequent mutated genes in AML with a hot spot mutation at codon R882 in 80% of the DNMT3A mut cases. In most of the studies DNMT3A mut predicts for poor overall (OS) and relapse-free survival (RFS). Recently, DNMT3A mut have been associated with age-related clonal hematopoiesis, and they have been identified in early preleukemic stem cells. These findings suggest that DNMT3A mut represents an early event in leukemogenesis and may be part of the leukemia founder clone in most AMLs harboring a DNMT3A mut. We thought to address the question whether MRD monitoring in DNMT3A mut patients (pts) can be used for pr…
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 …
Does neoadjuvant FOLFOX chemotherapy improve the prognosis of high‐risk Stage II and III colon cancers? Three years' follow‐up results of the PRODIGE…
2021
International audience; Aim Neoadjuvant chemotherapy has proven valuable in locally advanced resectable colon cancer (CC) but its effect on oncological outcomes is uncertain. The aim of the present paper was to report 3-year oncological outcomes, representing the secondary endpoints of the PRODIGE 22 trial. Method PRODIGE 22 was a randomized multicentre phase II trial in high-risk T3, T4 and/or N2 CC patients on CT scan. Patients were randomized between 6 months of adjuvant FOLFOX (upfront surgery) or perioperative FOLFOX (four cycles before surgery and eight cycles after; FOLFOX perioperative). In wild-type RAS patients, a third arm testing perioperative FOLFOX-cetuximab was added. The pri…
Long-Term Survival Data in 652 Patients with Primary Myelofibrosis or Polycythemia Vera— Trends in Recent Years.
2009
Abstract Abstract 2910 Poster Board II-886 Background: Polycythemia vera (PV) and primary myelofibrosis (PMF) are stem cell-derived myeloproliferative neoplasms characterized clinically by increased red cell volume and bone marrow fibrosis, respectively. Phlebotomy is the cornerstone of treatment in PV whereas hydroxyurea has been the traditional drug of choice in both PV and PMF. Over the last 20 years, several new treatment approaches have been introduced and promoted (e.g. interferon-alpha, anagrelide, thalidomide, allogeneic stem cell transplantation) but their benefit in terms of survival has not been confirmed in controlled studies. Methods: Study patients were recruited form the Mayo…
An Ordinal Joint Model for Breast Cancer
2017
We propose a Bayesian joint model to analyze the association between longitudinal measurements of an ordinal marker and time to a relevant event. The longitudinal process is defined in terms of a proportional-odds cumulative logit model and the time-to-event process through a left-truncated Cox proportional hazards model with information of the longitudinal marker and baseline covariates. Both longitudinal and survival processes are connected by a common vector of random effects.
Adding chemotherapy to TKI: Can we improve first-line treatment for EGFR-mutated NSCLC patients?
2016
In The Journal of Clinical Oncology , Ying Cheng and colleagues (1) have recently reported the results of a phase II randomized trial comparing pemetrexed plus gefitinib vs. gefitinib in treatment-naive, East Asian patients, with advanced non-squamous non-small cell lung cancer (NSCLC) and activating epidermal growth factor receptor (EGFR) mutations. The study met its primary end-point in the intent-to-treat population, showing a significantly longer median progression free survival (PFS) in favors of the combination arm (15.8 months) compared to single agent arm (10.9 months) [hazard ratio (HR): 0.68; 95% CI, 0.48 to 0.96; one-sided P=0.014; two-sided P=0.029].
Prognostic value of immunoexpression of CCR4, CCR5, CCR7 and CXCR4 in squamous cell carcinoma of tongue and floor of the mouth.
2018
Background Diverse studies have evidenced that chemokines can play a critical role in pathogenesis of oral squamous cell carcinoma (SCC). The main chemokines involved in oral carcinogenesis, tumor invasion and metastasis are CCR4, CCR5, CCR7 and CXCR4, and our aim was to evaluate the prognostic value of the immunoexpression of these chemokines in SCC of tongue and floor of the mouth. Material and Methods A retrospective descriptive study of the immunohistochemical expression of CCR4, CCR5, CCR7 and CXCR4 in paraffin-embedded samples of 124 patients with SCC of the tongue and floor of the mouth was performed, considering 98 cases from Brazil and 26 cases from Chile. Associations between vari…
Adjusted comparison between elotuzumab and carfilzomib in combination with lenalidomide and dexamethasone as salvage therapy for multiple myeloma pat…
2021
The lack of a randomized trial comparing carfilzomib (K) versus elotuzumab (Elo) associated with lenalidomide and dexamethasone (Rd) prompted us to assess the relative usefulness of one triplet over the other. Five independent retrospective cohorts of 883 relapsed/refractory multiple myeloma (RRMM) patients, including 300 EloRd and 583 KRd cases, outside clinical trials, entered this non-randomized comparison. KRd cohort accounted for a higher incidence of younger patients, cases with ≥3 lines of therapy, already exposed to lenalidomide, International Staging System (ISS) stage III, and abnormal lactic dehydrogenase (LDH) level compared with EloRd cohort. Moreover, cytogenetic risk categori…
Long-Term Efficacy of Maintenance Therapy for Multiple Myeloma: A Quantitative Synthesis of 22 Randomized Controlled Trials
2018
We aimed to quantitatively synthesize data from randomized controlled trials (RCTs) concerning maintenance for multiple myeloma (MM). We searched electronic literature databases and conference proceedings to identify relevant RCTs. We selected eligible RCTs using predefined selection criteria. We conducted meta-analysis comparing maintenance containing new agents and conventional maintenance, and subgroup analysis by transplantation status and mainstay agent as well. We performed trial sequential analysis (TSA) to determine adequacy of sample size for overall and subgroup meta-analyses. We performed network meta-analysis (NMA) to compare and rank included regimens. A total of 22 RCTs involv…
Lymphoma Symptoms: Data from a Phase 3, International, Randomized, Open-Label, Multicenter Study in Patients with Previously Treated Mantle Cell Lymp…
2015
Abstract Introduction MCL is an incurable aggressive B-cell lymphoma with a poor overall prognosis. For patients with MCL who fail initial therapy (ie, with relapsed or refractory [R/R] disease), treatment options historically have been limited. While remission duration is generally short, the goal of therapy has been to achieve remission while balancing treatment-related toxicities. Consequently, a substantial proportion of patients continuously suffer from lymphoma symptoms and other disease signs, such as itching and trouble sleeping or concentrating. Additionally, worries and high emotional sensitivity lead to reduced functional status and well-being. Therefore, it is crucial to any tre…
