| 中文摘要: |
| 中国原发性肝癌的新发病例数和死亡数均居世界首位,立体定向体部放射治疗(SBRT)技术以显著提高靶区照射精度,同时降低周围正常组织受照剂量而受到重视,其中呼吸运动管理是其中的关键技术。腹部加压技术作为呼吸运动管理中的重要手段,凭借其操作简便,适用性强等优势,在肝癌SBRT的呼吸运动管理中得到了广泛应用。肝脏的腹部加压技术还能有效减少肿瘤靶区的运动幅度,进而缩小内部靶区体积(ITV)的外扩范围,进一步提高靶区的照射剂量,降低周围正常组织的受照剂量。本文聚焦于肝脏呼吸运动管理、腹压技术运用、腹压装置改进以及腹部加压效果评价方法等研究领域,对腹部加压技术在肝癌SBRT中的应用进展进行综述,旨在为临床实践提供有益的参考借鉴。 |
| 英文摘要: |
| 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. |
