Abstract:
Both the incidence and mortality of primary liver cancer in China rank first globally. Stereotactic body radiotherapy (SBRT) is valued for its ability to significantly enhance the irradiation precision of target volumes while reducing the radiation doses to surrounding normal tissues. Respiratory motion management represents a critical SBRT technology. Meanwhile, abdominal compression has been extensively applied as a critical approach to respiratory motion management thanks to its convenient operation and high applicability. Furthermore, applying abdominal compression to the liver can effectively reduce the extent of motion of the gross target volumes, thus reducing the expanding ranges of the internal target volumes (ITVs). This further contributes to increased radiation dose to target volumes and decreased radiation dose to surrounding normal tissues. Focusing on respiratory motion management for the liver, the application of abdominal compression, improvements in abdominal compression devices, and method for assessing the abdominal compression effects, this study presents a review of advances in research on the application of abdominal compression in SBRT for liver cancer, aiming to provide a valuable reference for clinical practice.
