非小细胞肺癌放射治疗的剂量分割研究进展

Progress of dose fraction in radiotherapy for non-small cell lung cancer

放疗是局限晚期非小细胞肺癌患者的主要治疗手段,改变不同的剂量分割方式是提高放疗疗效的手段之一。不同的剂量分割方式有不同的优缺点,当然也适用于不同的患者。我们将对非小细胞肺癌放射治疗不同的剂量分割方式作一综述。

Radiotherapy is one of the main treatment options for patients with advanced limited non small cell lung cancer. From the viewpoint of radiobiology, the change of fractionation schedule in radiotherapy might improve the therapet, tic effect. There are many different methods of fractionated irradiation： from conventional radiation including hyperfractionated radiotherapy, accelerated radiotherapy and hypofractionated radiotherapy, etc. In this paper, we summarized the definition of the different types of fractionated irradiation, and its clinical application.
