Stereotactic body radiation therapy (SBRT) has become an important radical approach for early stage non-small cell lung cancer, especially for patients who are inoperable or refuse surgery. In China, this precision radiotherapy technology is being popularized. In order to standardize clinical application, improve the cooperation of technology and scientific research, this expert consensus is established. The consensus includes a brief introduction to the development of SBRT, the physical and technical requirements, the clinical implementation standardization and special clinical problems. The promotion and application of the consensus in clinical practice and constantly updated according to the latest research results will benefit more and more lung cancer patients.
