Chinese Expert Consensus on Online Adaptive Radiotherapy for Lung Cancer

Abstract： Lung cancer is the malignant tumor with the highest morbidity and mortality. Precision radiotherapy can significantly improve tumor control and reduce treatment-related toxicities， among which online adaptive radiotherapy based on image-guided radiotherapy can dynamically adjust the radiotherapy area and dose based on real-time image before each radiotherapy， and has been gradually applied to the treatment of lung cancer. In order to standardize clinical application， improve the cooperation of technology and scientific research of online adaptive radiotherapy for lung cancer， this expert consensus is established. This consensus combined theory and practice， and elaborated the physical and technical requirements， the clinical implementation standardization and common clinical problems of the online adaptive radiotherapy for lung cancer， so as to provide better reference for understanding and implementing this precision radiotherapy technology in hospitals of different levels， so that more patients with lung cancer can benefit from radiotherapy.
