传统的大体积肿瘤放疗有一定的局限性。空间分割放射治疗(GRID)和强度调制放射治疗(IMRT)是先进的调制束治疗的例子,有助于显著减少正常组织损伤。GRID是指将单一的高剂量辐射输送到一个大的治疗区域,该治疗区域被分成几个较小的区域,而IMRT与传统的三维适形放疗相比,可以改善剂量与肿瘤靶标的一致性。在这篇综述中,我们考虑了以GRID和IMRT为重点的空间分割放疗方法,并提供了来自不同研究的补充证据,这些研究支持辐射诱导的信号效应在这些治疗的总体放射生物学原理中的作用。
Traditional radiotherapy of bulky tumors has certain limitations. Spatially fractionated radiation therapy (GRID) and intensity modulated radiotherapy (IMRT) are examples of advanced modulated beam therapies that help in significant reductions in normal tissue damage. GRID refers to the delivery of a single high dose of radiation to a large treatment area that is divided into several smaller fields, while IMRT allows improved dose conformity to the tumor target compared to conventional three-dimensional conformal radiotherapy. In this review, we consider spatially fractionated radiotherapy approaches focusing on GRID and IMRT, and present complementary evidence from different studies which support the role of radiation induced signaling effects in the overall radiobiological rationale for these treatments.
