The efficacy of allografting in acute lymphoblastic leukemia (ALL) is heavily influenced by remission status at the time of transplant. Using polymerase chain reaction (PCR)-based minimal residual disease (MRD) analysis, we have investigated retrospectively the impact of submicroscopic leukemia on outcome in 64 patients receiving allogeneic bone marrow transplantation (BMT) for childhood ALL. R...
Transl Pediatr 2013;2(1):43-45 www.thetp.org In acute myeloid leukemia (AML), achievement of morphologic complete remission (RC) still remains the “gold standard” to make a judgment on treatment response and yet hematologists wonder about its utility in the era of minimal residual disease (MRD) detection. In fact, whatever the techniques used, a number of studies has convincingly demonstrated t...
The origin and evolution of novel biochemical functions remains one of the key questions in molecular evolution. We study recently emerged methacrylate reductase function that is thought to have emerged in the last century and reported in Geobacter sulfurreducens strain AM-1. We report the sequence and study the evolution of the operon coding for the flavin-containing methacrylate reductase (Mr...
Acquired drug resistance in childhood T-cell acute lymphoblastic leukemia (T-ALL) remains a significant clinical problem. In this study, a novel gene therapy target for childhood T-ALL to overcome chemoresistance was discovered: TFDP3 increased in the minimal residual disease (MRD) positive childhood T-ALL patients. Then, we established a preclinical model of resistance to induction therapy to ...
Epigenetic changes play an important role in leukemia pathogenesis. DNA methylation is among the most common alterations in leukemia. The potential role of DNA methylation as a biomarker in leukemia is unknown. In addition, the lack of molecular markers precludes minimal residual disease (MRD) estimation for most patients with hematologic malignancies. We analyzed the potential of aberrant DNA ...
To evaluate the effect of post-transplant imatinib administration, 34 Philadelphia chromosome-positive acute lymphoblastic leukaemia (Ph(+)ALL) patients were retrospectively analysed, with 7 receiving post-transplant imatinib administration. Overall survival was significantly better in patients with post-transplant administration (66.7% vs. 29.6% at 3 years, p=0.03), with no significant differe...
We asked whether minimal residual disease (MRD) determined by RUNX1/RUNX1T1 transcript levels could identify allogeneic hematopoietic stem cell transplantation (allo- HSCT) t(8;21) (q22;q22) acute myeloid leukemia patients who are at high risk for relapse, together with the impact of c-KIT mutations. Ninety-two consecutive adult t(8;21) patients who received allo-HSCT in complete remission were...
Increasing therapeutic options and prolonged survival in multiple myeloma have raised interest in the concept of depth of response and its importance to predict patients' outcomes. Although the efficacy of current treatment approaches has greatly improved in the past decade, the definition of complete response (CR) remains unaltered and continues to use conventional serological and morphologic ...
The effectiveness of rituximab maintenance therapy in the treatment of chronic lymphocytic leukemia has been investigated in a phase 2 clinical trial that included an initial treatment with rituximab 500 mg/m2 on day 1 (375 mg/m2 the first cycle), fludarabine 25 mg/m2 on days 1 to 3, cyclophosphamide 200 mg/m2 on days 1 to 3, and mitoxantrone 6 mg/m2 on day 1 (R-FCM), for 6 cycles, followed by ...
PURPOSE Apoptosis is an important mechanism regulating survival of acute myeloid leukemia cells. The apoptosis-related protein profile at diagnosis is important for achieving complete remission thereby affecting survival variables such as disease-free survival (DFS) and overall survival (OS).To investigate the role of the apoptosis protein profile in further response to therapy and outgrowth of...
