P3.14-008 Clinical Characteristics Matrix of Lung Tumor Under Stereotactic Ablative Body Radiotherapy (SABR)

Early Stage lung cancer can be treated with surgical resection and SABR. In clinical practice, it may be important to find a characteristic matrix for precision radiotherapy. The characteristic matrix for a lung tumor should include: 1) a time factor that incorporates the motion pattern of the tumor, 2) spatial factor which is related to volumetric information including location and surrounding environment, and 3) intrinsic characteristics which are related to the biologic information and could be represented by imaging characteristics. In this investigation, the typical heterogeneous characteristics matrix of lung tumors treated with SABR were studied.
