On December 4, 2025, the American Association for Cancer Research (AACR) released its inaugural AACR Pediatric Cancer Progress Report, which highlights the remarkable scientific and clinical advances transforming outcomes for children (ages 0-14) and adolescents (ages 15-19) with cancer. This first-of-its-kind report encompasses progress against pediatric cancers made over the past decade and chronicles major developments in molecularly targeted therapies, immunotherapies, and genomic profiling that are reshaping pediatric cancer diagnosis, surveillance, and treatment. The report also underscores the enduring challenges that impede progress, including the lack of effective therapies for rarer and aggressive pediatric cancers and the persistent inequities in access to high-quality treatment and supportive care, both in the United States and worldwide. Collectively, these insights reaffirm the urgent need for increased federal investment, strengthened international collaboration, and innovative research strategies to accelerate progress against pediatric cancer.
