Call for Research to Prioritize Early Detection
Experts in childhood cancer are calling for increased research into population screening and targeted surveillance, aiming to enhance early diagnosis. A recent review, published in EJC: Paediatric Oncology, emphasizes the need for increased focus on identifying children at risk of developing cancer. Despite childhood cancer being the leading cause of disease-related deaths in children aged 0-14 in the UK, with 1,900 new cases diagnosed annually, early diagnosis remains a significant challenge.
The Importance of Early Detection
The review, titled “A Review Calling for Research Directed at Early Detection of Childhood Cancers: The Clinical, Scientific, and Economic Arguments for Population Screening and Surveillance,” highlights the potential of population screening and targeted surveillance to detect cancer sooner. Research indicates that many childhood cancers are linked to genetic mutations or inherited predispositions. Identifying these risks early could lead to timely interventions, improving both survival rates and quality of life for young cancer patients.
Expert Opinions on Screening Benefits
David Walker, Emeritus Professor of Paediatric Oncology at the University of Nottingham and lead author of the paper, stressed the importance of early detection: “Spotting symptoms early is a challenge for families and healthcare providers. Investing in research to detect cancer before symptoms appear could offer a game-changing solution, giving all children a better chance at recovery.”
Population screening is already a standard practice for certain childhood diseases, even though the likelihood of developing cancer by the age of 18 is higher than for many of these conditions. The paper argues for a stronger commitment to developing screening programmes for childhood cancers, similar to those already in place for some adult cancers.
Potential of Population Screening
The review proposes that population screening would allow healthcare providers to reassure most children that they are not at risk of developing cancer while identifying those who are. Targeted surveillance would then monitor at-risk children through clinical tests and imaging, allowing for prompt diagnosis if cancer develops. However, further research is needed to establish effective screening programmes.
Expanding Genetic Screening
Dr. John Apps, Associate Clinical Professor in Paediatric Neuro-Oncology at the University of Birmingham and co-author of the paper, added: “As we gain a better understanding of cancer biology, we are learning that some children carry genetic mutations that increase their risk of developing cancers. For some of these conditions, like retinoblastoma, screening is already in place. However, as we discover more genetic predispositions, it’s crucial to develop guidelines for screening siblings and family members.”
A Parent’s Perspective
Tori Reeve, whose son Wilf was diagnosed with stage 4 Wilms’ tumour in June 2022, shares her personal experience of the need for earlier diagnosis. Wilf’s cancer was only detected after he started experiencing pain and nausea, and he underwent months of intensive chemotherapy and surgery. While Wilf is now in remission, Tori believes that earlier detection could have spared him some of the physical and psychological challenges of his treatment.
Tori explained, “Wilf hated the treatment and fought it every step of the way. It’s heartbreaking as a parent to see your child go through such a difficult time, knowing there’s no choice. Earlier detection could have made a real difference.”
Advancing Research for Early Detection
Dr. Tim Ritzmann, Clinical Associate Professor in Paediatric Neuro-Oncology at the Children’s Brain Tumour Research Centre, University of Nottingham, emphasized the importance of broadening the conversation: “This paper marks the beginning of a crucial discussion on how we can diagnose childhood cancers before they cause serious complications. Our international team of experts is dedicated to finding better ways to detect and intervene early.”
A Key Priority for Cancer Research
Ashley Ball-Gamble, CEO of Children’s Cancer and Leukaemia Group (CCLG) and co-author of the review, added: “Accelerating the detection of cancer in children and young people should be a top priority for cancer research. We want to ensure childhood cancers receive the attention they deserve in the search for earlier diagnosis and better outcomes.”
