Monitoring circulating cell DNA in pediatric non-Hodgkin lymphoma

The Value of Monitoring Circulating Cell DNA (ctDNA) in Pediatric Lymphoma: A Prospective, Multicenter Clinical Study

Observational Sun Yat-sen University · NCT04957901

This study is trying to see if tracking tumor DNA in the blood can help doctors predict how well treatment works and if cancer comes back in kids with non-Hodgkin lymphoma.

What this trial studies

This observational study aims to evaluate the significance of circulating tumor DNA (ctDNA) in predicting treatment efficacy and recurrence in pediatric patients diagnosed with mature B-cell non-Hodgkin lymphoma (NHL). Utilizing next-generation sequencing, tumor tissue and plasma samples will be collected from patients before, during, and after treatment to analyze genetic mutations. The study follows the modified BFM-95 protocol for treatment and includes a comprehensive assessment of chemotherapy response. By understanding the mutation landscape, the study seeks to improve treatment strategies for this patient population.

Who should consider this trial

Good fit: Ideal candidates are children under 18 years old with newly diagnosed mature B-cell lymphoma requiring treatment.

Not a fit: Patients with incomplete baseline samples or those not meeting the inclusion criteria will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the ability to predict treatment outcomes and recurrence in pediatric non-Hodgkin lymphoma patients.

How similar studies have performed: Other studies utilizing ctDNA monitoring in various cancers have shown promising results, indicating potential success for this approach in pediatric NHL.
