摘要Objective:This study explains the application number and funding rate of oncology projects undertaken by the National Natural Science Foundation of China(NSFC),with focus on tumor radiotherapy-related research over the past 11 years.Methods:A stratified analysis was carried out on the application and funding status of tumor radiotherapy studies in different NSFC project categories,different research areas,and different tumor types.Research areas that required specific focus,such as immunology-related radiotherapy,multimodality imaging and radiomics,and post-radiotherapy organ injury,were separately analyzed.Results:The status and development trends of various related research fields were studied,and the research results were presented with the support of the NSFC,in order to provide reference for future applications and funding allocations.Conclusion:The number of applications for funding increases every year.Although the total number of funded projects has also increased every year,the funding rate has decreased year by year.Projects on radiotherapy and immunization have been at the forefront in recent years,and the funding rate for these projects increases yearly.
