摘要: 肺癌立体定向放疗的主要技术包括调强放疗(IMRT)、容积旋转调强放疗(VMAT)和螺旋断层放疗(HT)。3种技术在靶区适形度及剂量均匀性方面,HT和VMAT要优于IMRT,但HT和VMAT技术会增加肺的低剂量区受照体积。VMAT较其他两种技术可明显缩短治疗时间。目前,对于不同位置、不同分期的肺部肿瘤,如何个体化地选择最佳放疗技术仍存有一定的争议。

Abstract: The radiation techniques for lung cancer stereotactic body radiotherapy (SBRT) include intensity modulated radiation therapy (IMRT), volumetric modulated arc therapy (VMAT) and helical tomotherapy (HT). Concerning the target conformity and dosimetric homogeneity index, HT and VMAT technologies are superior to IMRT. On the contrary, HT and VMAT technology can increase low dose area irradiated of lung. Comparing to other two technologies, VMAT can obviously shorten the treatment time. At present, there is no consensus how to choose individually optimized radiotherapy technology for different location and stages lung tumors.
