Significance Of Minimal Residual Disease Detected By Multi-Color Flow Cytometry In Childhood Acute Myeloid Leukemia With The Intermideate-Risk Cytogenetics and Negative FMS-Like Tyrosine Kinase 3Internal Tandem Duplication: A Report Of The Tokyo Children's Cancer Study Group

Response to induction chemotherapy is one of the most important predictors of outcome in acute myeloid leukemia (AML) as well as cytogenetics and molecular genetics. Measurement of minimal residual disease (MRD) by flow cytometry is an informative method for assessment of initial treatment response, but the heterogeneity of leukemia-associated antigens and antigen shifts during treatment limit its sensitivity and specificity. We prospectively evaluated the prognostic prevalence of MRD monitoring using multi-color flow cytometry in children with AML treated on the Japanese Pediatric Leukemia/Lymphoma Study Group (JPLSG) AML-05 trial.
