Monitoring minimal residual disease in children with B-acute lymphoblastic leukemia

A Study to Assess Minimal Residual Disease by Next-generation Sequencing of Immunoglobulin Gene Rearrangements in Pediatric B-acute Lymphoblastic Leukemia

Sun Yat-sen University · NCT04977895

This study tests if a new DNA testing method can better track leftover cancer cells in children with B-acute lymphoblastic leukemia to help predict relapses and improve treatment outcomes.

What this trial studies

This observational study investigates the effectiveness of next-generation sequencing (NGS) techniques in measuring minimal residual disease (MRD) in pediatric patients with B-acute lymphoblastic leukemia (B-ALL). It compares the sensitivity and specificity of IgH-V(D)J NGS against traditional flow cytometry in detecting MRD during treatment. The study aims to predict disease relapse and assess prognosis by monitoring MRD at multiple time points during therapy. By identifying trackable clones in diagnostic samples, the study seeks to improve early intervention strategies and enhance survival rates.

Who should consider this trial

Good fit: Ideal candidates for this study are children under 18 years old who have been newly diagnosed with B-acute lymphoblastic leukemia and have not received prior treatment.

Not a fit: Patients with a history of other malignancies, active infections, or uncontrolled autoimmune diseases may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more accurate monitoring of MRD, improving treatment outcomes and survival rates for children with B-ALL.

How similar studies have performed: Other studies have shown success with similar NGS approaches for MRD detection, indicating a promising avenue for improving patient outcomes.
