Clinical significance of minimal residual disease in adult acute lymphoblastic leukemia

Clinical significance of minimal residual disease quantification in adult patients with standard-risk acute lymphoblastic leukemia.

Adult patients with acute lymphoblastic leukemia (ALL) who are stratified into the standard-risk (SR) group due to the absence of adverse prognostic factors relapse in 40% to 55% of the cases. To identify complementary markers suitable for further treatment stratification in SR ALL, we evaluated the predictive value of minimal residual disease (MRD) and prospectively monitored MRD in 196 strict...

Minimal residual disease in acute lymphoblastic leukemia.

In patients with acute lymphoblastic leukemia (ALL), monitoring of minimal residual disease (MRD) offers a way to precisely assess early treatment response and detect relapse. Established methods to study MRD are flow cytometric detection of abnormal immunophenotypes, polymerase chain reaction (PCR) amplification of antigen-receptor genes, and PCR amplification of fusion transcripts. The strong...

The relation between end of induction minimal residual disease and different risk factors in patients with acute lymphoblastic leukemia

Background: Malignant disorder with B or T stem cell basis leads to development and continuation of acute lymphoblastic leukemia (ALL) due to aggregation of blast cells in bone marrow. The environmental, genetic, and demographic factors may influence the disease relapse. The objective of this study was to assess the relation between end of induction minimal residual disease and different risk f...

Evaluation of Relationship between Minimal Residual Disease (MRD) and Relapse in Childhood Acute Lymphoblastic Leukemia (ALL) Using Quantitative Fluorescent PCR

Detection of Minimal Residual Disease in Acute Lymphoblastic Leukemia

MRD diagnostics during the first three months of treatment has proven to be of high value in pediatric acute lymphoblastic leukemia (ALL), because of its potential to recognize subgroups that differ substantially in outcome. Consequently, MRD diagnostics is now being used for treatment intervention, both treatment intensification (including stem cell transplantation) and treatment reduction. Ho...
