Objective To conduct a scoping review of studies related to gamified physical activity interventions for pediatric cancer patients，and to extract the gamification elements and application effects within physical activity intervention programs. Methods A computer-assisted search was conducted in CNKI，Wanfang Data，VIP Database，China Biology Medicine disc，Cochrane Library，PubMed，Embase，and Web of Science for studies on gamified physical activity interventions in pediatric cancer patients，with a search period from database inception to December 31，2023. The included literature was screened，summarized，and analyzed. Results A total of 18 articles were included，including 9 randomized controlled trials，4 quasi-experimental studies，and 5 mixed-method studies. The gamified intervention programs for physical activity in children with cancer integrated 7 gamification elements，including goal setting，capacity to overcome challenges，providing feedback on performance，reinforcement，progress monitoring，social connectivity，and fun and playfulness. The types of physical activity in the intervention programs included aerobic exercise，balance training，strength training，endurance training，etc. The intensity of the activities was mainly low to moderate；the duration was mostly 30~60 minutes per session；the intervention duration ranged from 5 weeks to 1 year. Numerous research findings indicate that gamified physical activity interventions for children with cancer can help improve physical function，quality of life，and fatigue levels. However，there is signi-ficant controversy regarding their impact on improving physical activity levels. Conclusion The gamified inter-vention for physical activity in children with cancer was safe and feasible. It is recommended that in the future，personalized and phased gamified intervention programs should be developed to evaluate the intervention effects.
