Overview of the Study
A recent study conducted by researchers from University College London (UCL) and Fondazione IRCCS Istituto Nazionale dei Tumori in Milan (INT) has revealed significant disparities in childhood cancer survival rates across Europe and other regions, primarily attributed to the stage of tumor at diagnosis. Analyzing data from nearly 10,000 children diagnosed with six types of cancer—neuroblastoma, Wilms tumor, medulloblastoma, osteosarcoma, Ewing sarcoma, and rhabdomyosarcoma—across 27 countries, the study highlights the critical role of early and accurate diagnosis in improving survival outcomes.
Key Findings
The research, published in JAMA Network Open, indicates that survival rates at three years post-diagnosis are closely linked to the tumor stage at diagnosis. For instance, children diagnosed with neuroblastoma in the UK and Ireland exhibited lower survival rates compared to those in Central Europe, a difference attributed to later-stage diagnoses in these regions. The study also found that while Ewing sarcoma survival rates were lower in the UK and Eastern Europe, this was not solely due to diagnosis stage, suggesting additional factors may influence outcomes.
Importance of Early Diagnosis
Professor Kathy Pritchard-Jones, a lead author of the study, emphasized the necessity of timely diagnosis and accurate assessment of tumor spread, stating, “Our findings show that diagnosing cancer earlier and accurately assessing how far it has spread can make a meaningful difference to survival for many children.” The study underscores that while early diagnosis is crucial, it alone cannot resolve all disparities in survival rates, necessitating further investigation into treatment approaches and healthcare access.
Criticism and Calls for Action
Charities and healthcare advocates have responded to the findings with calls for improved diagnostic processes. Ashley Ball-Gamble, chief executive of the Children & Young People’s Cancer Association, noted, “This study confirms that, for some childhood cancers, diagnosis in the UK still takes longer than it should.” Angela Polanco, whose daughter survived Wilms tumor, echoed this sentiment, advocating for timely and accurate diagnosis and treatment access for all children.
Conflicting Reports & Gaps
While the study provides robust evidence linking diagnosis stage to survival rates, it also highlights the complexity of cancer care. For Ewing sarcoma, lower survival rates persisted even after accounting for tumor stage, indicating that factors such as treatment protocols and healthcare system differences may also play significant roles. The study's limitations include a three-year follow-up period, which may not capture all long-term survival outcomes.
What's Next
The BENCHISTA project, which facilitated this research, aims to further explore the systemic factors affecting childhood cancer survival rates. Future phases will analyze five-year survival data and continue to refine data collection methods across participating countries, with the goal of informing health policies that enhance early detection and treatment access.

- “Angela Polanco, whose daughter Bethany was diagnosed with Wilms tumour, said: “This study provides clear evidence that we need to do more to ensure children affected by cancer have access to timely and accurate diagnosis, appropriate first-line treatment, and specialist care, wherever they live.” — Angela Polanco, Patient Advocate
- “Because delays can affect a child’s chance of survival, campaigning for faster recognition is more important than ever.” — Ashley Ball-Gamble, Chief Executive, Children & Young People’s Cancer Association
- “Our results provide the first population-based and international evidence that, in some countries, paediatric tumors are diagnosed at more advanced stages compared to a group of European countries with the most consistent practices, while in others, staging procedures do not meet recommended standards – clearly impacting prognosis.” — Professor Kathy Pritchard-Jones, UCL
This comprehensive study sheds light on the urgent need for improvements in childhood cancer diagnosis and treatment, aiming to ensure that all children have equitable chances of survival, regardless of their geographical location.
