Understanding Why Neuroblastoma Returns and Stops Responding to Treatment
Project Number : 26-VIVO-02; Gudrun Schleiermacher
Using samples from the international BEACON trial
1) What is this research about?
Neuroblastoma is a childhood cancer that develops in nerve tissue. While many children respond well to treatment, some experience a relapse, where the cancer returns or stops responding to therapy. Outcomes for these children remain poor. This study aims to understand how neuroblastoma changes over time, particularly between diagnosis, treatment, and relapse. By studying tumour samples and blood samples collected through the international BEACON clinical trial, researchers hope to identify the biological changes that allow cancer cells to survive treatment and return.
2) Why is it important?
Relapsed neuroblastoma is one of the most difficult childhood cancers to treat. Researchers know that cancer cells can evolve during treatment, but the reasons why some tumours become resistant are not fully understood. A better understanding of these changes could help doctors predict which treatments are most likely to work and identify new targets for future therapies.
3) What are the researchers doing?
The team will analyse tumour tissue and blood samples from children enrolled in the BEACON trial. They will study genetic and biological changes in cancer cells and track tumour DNA circulating in the bloodstream over time. By comparing samples taken at diagnosis, during treatment, and after relapse, the researchers will investigate how neuroblastoma evolves, develops resistance to treatment, and spreads. They will also look for biomarkers that may help predict how patients will respond to therapy.
4) How could this help patients in the future?
This research could reveal why some neuroblastomas become resistant to treatment and identify new ways to target these cancers. It may also lead to blood-based tests that help doctors monitor disease more closely and detect important changes earlier. Ultimately, the findings could support more personalised treatment approaches, improve outcomes for children with relapsed neuroblastoma, and guide the development of new therapies for this aggressive disease.
