Pediatric Cancer Biomarkers Market Expands as Demand for Targeted Therapies Grows


The global pediatric cancer biomarkers market is on a strong upward trajectory, projected to grow from US$ 909.6 million in 2025 to US$ 1,642.4 million by 2032, reflecting a healthy CAGR of 8.8%. Fueled by advancements in genomics, proteomics, and metabolomics, the market is rapidly evolving to support early diagnosis, precise treatments, and improved survival rates in childhood cancer.

Growing Significance of Biomarkers in Pediatric Oncology

Pediatric cancers differ biologically from adult malignancies, necessitating a more personalized and nuanced approach to diagnosis and treatment. Biomarkers are increasingly being used to develop targeted therapies, optimize clinical decisions, and improve prognostic accuracy. The increasing adoption of high-throughput technologies and innovations in omics-based research has elevated the role of biomarkers in pediatric oncology.

Market Dynamics Driving Growth

Early Detection Fuels Demand

One of the primary drivers of market expansion is the global push for early detection of childhood cancers. According to the World Health Organization (WHO), approximately 400,000 children under the age of 19 are diagnosed with cancer annually. The demand for biomarker-based diagnostic tools that can detect malignancies at early, more treatable stages is rising sharply. A study published in 2024 by BMC Cancer demonstrated how artificial intelligence could enhance acute myeloid leukemia (AML) diagnosis through biochemical profiling of blood samples, achieving an impressive predictive AUC of 0.909 using a random forest model.

Challenges Due to Genetic Heterogeneity

However, the market also faces challenges. Pediatric tumors are genetically diverse, making it difficult to develop universal biomarkers that apply across different cancer types. Unlike adult cancers with well-known mutations, pediatric malignancies often exhibit rare or unique genetic patterns, requiring highly customized approaches. This adds to the complexity and cost of biomarker development, potentially limiting widespread application.

Technological Advancements Unlock New Opportunities

Despite these challenges, the metabolomics biomarker market is showing great promise. A study published in PLOS ONE in June 2023 identified 25 altered metabolites in pediatric medulloblastoma patients, six of which exhibited high diagnostic specificity. Technologies such as UPLC-Q/E-MS/MS are making it possible to understand the biochemical behavior of tumors, enhancing the precision of diagnostics.

Next-Generation Sequencing Paves the Way for Personalized Medicine

The integration of Next-Generation Sequencing (NGS) technologies such as RNA sequencing and Whole-Exome Sequencing (WES) has expanded the use of biomarkers in pediatric cancer. Studies show NGS produces clinically significant findings in approximately 66% of pediatric hematologic malignancies. At Sydney Children’s Hospital, personalized therapies enabled through NGS achieved complete or partial remission in 55% of pediatric patients, compared to just 12% in the standard care group.

Indication Insights: Leukemia Dominates

Among various cancer types, leukemia is projected to hold the largest share of around 41.7% by 2025. It accounts for approximately 25.4% of all childhood cancer cases in the U.S., with Acute Lymphoblastic Leukemia (ALL) comprising up to 80% of these. The high prevalence and well-defined genetic alterations in leukemia support robust research and development for biomarker identification.

Neuroblastoma, another major indication, is expected to witness substantial growth. According to the National Library of Medicine, it accounts for 8 to 10% of childhood cancers globally. Biomarkers such as ALK mutations and MYCN amplification have emerged as key diagnostic and therapeutic targets. The presence of these molecular markers is guiding the development of next-generation treatments, including ALK inhibitors like crizotinib, which have shown efficacy in clinical trials.

Biomarker Insights: CD19, CD20, and CD22 Lead

Among biomarker types, CD19, CD20, and CD22 are expected to collectively command a share of approximately 30.4% in 2025. These markers are instrumental in the diagnosis and treatment of B-cell malignancies, particularly B-cell Precursor Acute Lymphoblastic Leukemia (BCP-ALL). CD19 is widely used in monitoring minimal residual disease, while CD22 and CD20 are involved in B-cell receptor signaling and immune targeting, respectively.

ALK is another significant biomarker, especially in neuroblastoma. Around 8 to 10% of primary neuroblastoma tumors carry ALK mutations. These mutations activate the tyrosine kinase domain and drive tumor progression, making them ideal targets for emerging therapies.

Regional Insights: North America Leads, Asia Pacific Grows Rapidly

North America

North America is forecast to maintain its dominance with a projected 44.2% share of the global pediatric cancer biomarkers market in 2025. This growth is driven by strong federal support, such as the Childhood Cancer Data Initiative (CCDI), which allocates US$ 50 million annually to pediatric oncology research. States like Kentucky and Connecticut have passed legislation mandating insurance coverage for biomarker testing, promoting equitable access to precision diagnostics.

Advocacy efforts from groups like the American Cancer Society Cancer Action Network (ACS CAN) have also helped secure funding through the STAR Act. Personalized medicine is becoming increasingly prominent, with biomarker-based therapies offering more effective, individualized care for pediatric patients.

Europe

Europe is witnessing similar momentum. The region benefits from a well-coordinated ecosystem of healthcare providers, research organizations, and regulatory bodies. Institutions such as the Glasgow Precision Oncology Laboratory (GPOL) and EU-backed projects like ONCOCHECK are spearheading biomarker research. The European Society for Pediatric Oncology (SIOPE) continues to advocate for broader biomarker integration through initiatives like ERN PaedCan and JARC.

France reported leukemia as a leading pediatric cancer in 2024, while CNS tumors also gained prevalence. These trends are driving research and investment in biomarker development across the region.

Asia Pacific

In the Asia Pacific region, countries like China and India are witnessing a rapid rise in pediatric cancer cases, prompting governments and healthcare institutions to invest heavily in diagnostics. China's annual cancer caseload exceeds 4.5 million, highlighting the urgent need for early detection tools. Biomarkers are increasingly being utilized to deliver targeted therapies, reduce costs, and improve patient outcomes.

Technological innovation is further bolstering growth in this region. Japan’s genomic medicine initiatives and India’s Genome India Project are laying the foundation for biomarker-based diagnostics. NGS adoption is also expanding, facilitating better identification of molecular targets in pediatric cancers.

Competitive Landscape and Industry Developments

The pediatric cancer biomarkers market is highly competitive, with major players focusing on advanced research and strategic partnerships. Key companies such as F. Hoffmann-La Roche Ltd, Abbott, QIAGEN, Siemens Healthineers, Thermo Fisher Scientific, Beckman Coulter, Myriad Genetics, Agilent Technologies, Bio-Rad Laboratories, and BIOMÉRIEUX are at the forefront of innovation.

In December 2024, St. Jude Children’s Research Hospital identified 27 blood proteins that can predict cardiomyopathy in childhood cancer survivors exposed to anthracycline. Two biomarkers, NT-proBNP and GLS, proved highly accurate for risk prediction within five years.

In March 2024, the University of California, San Francisco, identified AF1q as a universal biomarker for neuroblastoma using data from the Broad Institute’s Cancer Cell Line Encyclopedia. AF1q, an oncoprotein involved in leukemia and solid tumor progression, was found to be significantly expressed in tumors of neural origin.

Future Outlook

The pediatric cancer biomarkers market is poised for substantial advancement as the medical community increasingly prioritizes early detection and precision medicine. Technologies such as NGS, metabolomics, and AI-powered diagnostics are reshaping how pediatric cancers are understood and treated.

With supportive regulatory frameworks, increased investment in R&D, and a growing awareness of personalized healthcare, the market is expected to continue its upward trajectory. By 2032, pediatric cancer biomarkers are set to become a cornerstone of pediatric oncology, ensuring timely diagnosis and targeted therapy for young patients worldwide.
