NCT06525116

Brief Summary

This retrospective analysis aims to investigate pediatric patients with T cell acute lymphoblastic leukemia who were detected for minimal residual disease (MRD) using next-generation sequencing (NGS). The study will utilize second-generation sequencing technology to analyze the rearrangement of the T cell receptor (TCR) genes in these patients. Patients will be stratified based on NGS-MRD levels, and the relationship between NGS MRD and Event-Free Survival (EFS) will be evaluated.
