ABSTRACT Background Proton beam therapy (PBT) offers dosimetric advantages in pediatric radiotherapy by reducing radiation exposure to healthy tissues. However, broad implementation raises important ethical, logistical, and equity considerations, especially in settings with limited access to advanced technologies. Procedure This position paper by the Paediatric Radiation Oncology Society (PROS) reviews the clinical rationale for selecting radiotherapy modalities in children, with a specific focus on ethical utilization of PBT. The document synthesizes evidence on the benefits and limitations of modern photon and proton therapies, explores disparities in access, outlines the role of local pediatric radiation oncologists, and addresses the impact of industry‐driven messaging on family decision‐making. Results While PBT offers clinical benefit in selecting pediatric cancers, high‐quality photon‐based treatments such as IMRT and VMAT remain effective and widely accessible alternatives. The referral and evaluation process for PBT is complex and may introduce treatment delays. Travel and financial burdens can exacerbate disparities. PROS underscores the critical role of local pediatric radiation oncologists in counseling families, and calls for balanced, evidence‐based communication from providers and industry stakeholders. Conclusions PROS advocates for an ethical, equitable, and evidence‐informed approach to radiotherapy modality selection in children, reflecting holistic considerations beyond dosimetry. Proton therapy should be pursued when clinically indicated and accessible without compromising timely care. Investment in a comprehensive radiation therapy infrastructure, including professional education, collaborative research, and responsible public messaging, is essential to optimize pediatric cancer outcomes globally.

ABSTRACT In 2005, the Paediatric Radiation Oncology Society (PROS), a multi‐professional association to promote radiotherapy for children and young people, was created. Its mission has been to educate those involved in this field, and to improve the standards of radiation oncology care for children, adolescents, and young adults across the globe, not least in less privileged settings where the majority of the world's children, and most with cancer, live. Through regular congresses, and joint meetings with the International Society of Paediatric Oncology (SIOP), PROS has facilitated a focus on this treatment modality, and advocated on behalf of those who might benefit from it.

AbstractTo examine the educational background, clinical practice, and preferences regarding continuing medical education (CME) among radiation oncologists who attended the 2019 meeting of the Pediatric Radiation Oncology Society (PROS), a survey consisting of 20 questions was distributed asking for demographic and educational background, clinical practice, and preferences regarding pediatric radiation oncology CME. Of 188 participants, 130 (69.2%) returned the questionnaire. More than 80% reported access to CT simulation, three‐dimensional radiotherapy, and general anesthesia while <30% had access to intraoperative radiotherapy, proton, and heavy particle therapy. After residency, 12.1% did further training in pediatric radiation oncology. When asked about further training in pediatrics after residency, 88.8% answered that there should be a formal training program beyond residency in order to treat children. More than 75% acquired knowledge in pediatric radiation oncology through journals, books, live meetings, and tumor boards. The results of this survey may help Pediatric Radiation Oncology Society (PROS) in creating guidelines and recommendations for improvement in pediatric radiation oncology training and practice support as well as the development of CME activities most likely to benefit practitioners.
