    This study enrolled 49 patients with de novo childhood acute lymphoblastic leukemia (ALL) and 19 adult patients with ALL. WT1 mRNA showed high positive expression rates of 90% or more in ALL patients, and fusion gene transcripts were detected in 22.4% of childhood ALL cases prior to treatment. During follow-up at 4-6 months, WT1 mRNA levels in childhood ALL cases were observed to be lower in patients undergoing hematological remission after treatment when compared to the initial stages. We also assessed hematological remission via ROC analysis. The upper cut-off values were calculated to be 220 and 1,820 copies/μg RNA in the peripheral blood (PB) and bone marrow (BM) samples, respectively. Since 50 copies/μg RNA was determined to be both, the limit of detection (LOD) and minimal residual disease (MRD) threshold, WT1 mRNA regions below the upper cut-off values indicated remission..
