近十余年来，大量资料表明头颈部鳞癌放疗中存在明显的时间—效应关系。总疗程时间延长会导致肿瘤局控率的降低；疗程中肿瘤细胞加速再增殖是其主要原因，基于该理论发展起来的缩短疗程的放疗方法被认为是放射肿瘤学的重要进展之一。作者综合分析有关非小细胞肺癌（ＮＳＣ... In recent ten years, a large amount of data shows that there is a significant time-effect relationship between radiotherapy of head and neck squamous cell carcinoma. Prolongation of the total duration of treatment will lead to the reduction of the tumor control rate. The main reason for the accelerated re-proliferation of tumor cells during the course of treatment is the development of short-course radiotherapy based on this theory is considered as one of the important advances in radiation oncology. Comprehensive analysis of the relevant non-small cell lung cancer (NSC ...
