The choice of either induction or postremission therapy for adults with acute myeloid leukemia is still largely based on the "one size fits all" principle. Moreover, pretreatment prognostic parameters, especially chromosome and gene abnormalities, may fail in predicting individual patient outcome. Measurement of minimal residual disease (MRD) is nowadays recognized as a potential critical tool ...
We read with interest the brief report by Edward Laane and co-workers published into Haematologica/ The Hematology Journal, June 2006. By multiparametric flow-cytometry (MPFC), the authors determined the levels of minimal residual disease (MRD) in 45 younger adult patients with acute myeloid leukemia (AML) in complete remission after induction therapy. They observed that receiving or not alloge...
BACKGROUND AND OBJECTIVES To date, bone marrow (BM) is the most common source of cells to use in order to assess minimal residual disease (MRD) in acute myeloid leukemia (AML). In the present study, we investigated whether peripheral blood (PB) could be an alternative source of cells for monitoring MRD in AML. DESIGN AND METHODS Fifty patients with AML were monitored for MRD after the achieve...
Minimal Residual Disease Evaluation in Childhood Acute Lymphoblastic Leukemia: An Economic Analysis.
BACKGROUND Minimal residual disease (MRD) testing by higher performance techniques such as flow cytometry and polymerase chain reaction (PCR) can be used to detect the proportion of remaining leukemic cells in bone marrow or peripheral blood during and after the first phases of chemotherapy in children with acute lymphoblastic leukemia (ALL). The results of MRD testing are used to reclassify th...
In this paper, we study properties of rank metric codes in general and maximum rank distance (MRD) codes in particular. For codes with the rank metric, we first establish Gilbert and sphere-packing bounds, and then obtain the asymptotic forms of these two bounds and the Singleton bound. Based on the asymptotic bounds, we observe that asymptotically Gilbert-Varsharmov bound is exceeded by MRD co...
Risk directed treatment forms a central component of modern protocols for childhood acute lymphoblastic leukaemia (ALL). A review of recent studies of minimal residual disease (MRD) analysis shows that it is a powerful prognostic factor in both first line and relapse treatment. However, the value of MRD analysis is both time point and protocol specific, and the threshold for MRD detection of th...
چکید ه سابقه و هدف میکرو RNA ها، نوعی از RNA های کوچک غیر کدکننده هستند و اخیراً مشخص شده که نقشی اساسی در فرآیندهای مهم سلولی از جمله تکامل و تمایز از طریق تنظیم پس از رونویسی، ایفا میکنند. میزان بیان میکرو RNA ها در ارتباط با بیماریزایی بعضی بدخیمیهای خونی از جمله لوسمی میلوئیدی حاد شناخته شده است . هدف از این مطالعه، بررسی بیان miR-150 و miR-155 در بیماری لوسمی میلوژنوس مزمن( CML ) ب...
Multiple Myeloma (MM) is an incurable malignant plasma cell disorder. We have evaluated the counts of Multiple Myeloma Cells (MMCs) and normal plasma cells (N-PCs), seven days after high-dose melphalan (HDM) and autologous stem transplantation (ASCT). Two third of patients had detectable minimal residual disease (MRD+) (71.7 MMCs/µL) after induction treatment with dexamethasone and proteasome i...
Tumor-related immunoglobulin heavy-chain (IgH) rearrangements are markers for polymerase chain reaction (PCR) detection of minimal residual disease (MRD) in B-cell malignancies. Nested PCR with patient IgH allele-specific oligonucleotide primers can detect 1 tumor cell in 10(4) to 10(6) normal cells. In childhood acute lymphoblastic leukemia (ALL), persistence of PCR-detectable disease is assoc...
In chronic lymphocytic leukemia (CLL), the detection of minimal residual disease (MRD) correlates with outcome in the trial setting. However, MRD assessment does not guide routine clinical management and its assessment remains complex. We incorporated detection of the B cell, tumor-specific antigen CD160 to develop a single-tube, flow cytometry assay (CD160FCA) for CLL MRD to a threshold of 10(...
