Radiotherapy and surgery are the principal curative modalities in treatment of head and neck cancer. Conventional two-dimensional and three-dimensional conformal radiotherapy result in significant side effects and altered quality of life. Intensity-modulated radiotherapy (IMRT) can spare the normal tissues, while delivering a curative dose to the tumour-bearing tissues. This article reviews the current role of IMRT in head and neck cancer from the point of view of normal tissue sparing, and also reviews the current published literature by individual head and neck cancer subsites. In addition, we briefly discuss the role of image guidance in head and neck IMRT, and future directions in this area.
放射治疗和手术是治疗头颈部癌症的主要方法。传统的二维和三维适形放射治疗会导致严重的副作用和生活质量下降。调强放疗(IMRT)可以保护正常组织,同时向肿瘤靶区提供治疗剂量。本文从保护正常组织的角度综述了 IMRT 在头颈部癌症中的作用,并按头颈部不同亚部位回顾了目前的文献。此外,我们还简要讨论了头颈部 IMRT 中图像引导的作用和该领域的未来发展方向。
