Objective: Ever-expanding technological advances have enabled many pediatric brain tumor patients to live longer and enjoy a better quality of life. Studies have shown that proton therapy spares more healthy tissue than photon radiation. However, proton therapy is more expensive, and questions remain regarding whether this cost is justified in terms of short and long-term health improvements. This research aims to determine if neurocognitive effects of photon versus proton beam radiation differ in pediatric brain tumor patients. Method: This is a retrospective review of clinical neuropsychological profiles from 39 pediatric brain tumor patients (24 males and 15 females; M = 9.6 years, SD = 2.2) who were evaluated prior to radiation therapy and 1 year after radiation completion. Eighteen patients received photon radiation and 21 received proton beam. Processing speed and working memory...
