CyberKnife Versus Four-Dimensional Computed Tomography-Guided Stereotactic Body Radiation Therapy in the Treatment of Lung Cancer: A Case Report

Stereotactic body radiation therapy (SBRT) has emerged as a critical therapeutic option for treating lung and other solid tumors. Two prominent high-precision SBRT techniques currently in use are four-dimensional computed tomography-guided linear accelerator-based SBRT (4DCT-SBRT) and CyberKnife. This case presents a patient diagnosed with two distinct pulmonary lesions, each treated separately using 4DCT-SBRT and CyberKnife. By comparing target delineation, dose distribution, lesion response, and the capability to spare normal tissues, we evaluate the specific advantages of CyberKnife for particular clinical scenarios.
