摘要

实时肿瘤跟踪容积调制弧治疗（RT-VMAT）可根据对内部标记物三维位置的连续 X 射线跟踪进行射束分流，这对移动肿瘤很有意义。我们对连续接受肝脏立体定向体放射治疗的十名患者的剂量-体积特征和治疗时间进行了评估。与RT-3D适形放疗相比，RT-VMAT的靶剂量适形性和对胃肠的保护得到了改善。每部分的平均治疗时间不到10分钟。RT-VMAT 疗效显著，尤其是对于邻近危险器官的靶点。

Clinical application of real-time tumor-tracking for stereotactic volumetric modulated arc therapy for liver tumors

Real-time tumor-tracking volumetric modulated arc therapy (RT-VMAT) enabling beam-gating based on continuous X-ray tracking of the three-dimensional position of internal markers is relevant for moving tumors. Dose-volume characteristics and treatment time were evaluated in ten consecutive patients who underwent liver stereotactic body radiation therapy with RT-VMAT. Target dose conformity and sparing of the stomach and the intestine were improved comparing RT-VMAT with RT-3D conformal radiotherapy. The mean treatment time for each fraction was less than 10 min. RT-VMAT could be effective, especially for targets located adjacent to organs at risk.
