Plasma-based transcriptomic non-coding signature for predicting relapse in pediatric acute lymphoblastic leukemia

Area of Science:

• Pediatric Hematology
• Oncology
• Molecular Diagnostics

Background:

• Pediatric Acute Lymphoblastic Leukemia (ALL) relapse significantly impacts prognosis.
• Current relapse prediction methods have limitations.
• Need for non-invasive, early diagnostic tools in pediatric ALL.

Purpose of the Study:

• Develop a blood-based, non-invasive method for predicting ALL relapse in children.
• Identify novel non-coding RNA biomarkers for relapse prediction.
• Create a risk stratification model incorporating these biomarkers.

Main Methods:

• Analysis of two pediatric ALL patient cohorts.
• High-throughput profiling to identify miRNA and circRNA expression.
• Logistic regression and nomogram development for predictive modeling.

Main Results:

• Identified three miRNAs and three circRNAs as potential relapse biomarkers.
• Expression of these non-coding RNAs increased from healthy controls to relapsed ALL.
• Combined non-coding RNA panel showed superior predictive ability and formed an independent predictor of relapse.

Conclusions:

• A blood-based non-coding RNA panel offers a promising non-invasive method for predicting pediatric ALL relapse.
• Integration with clinical features enhances predictive accuracy and risk stratification.
• This approach may significantly improve patient care and outcomes for pediatric ALL.
