决定放射治疗肿瘤成败的因素很多,多年来,无论在实验动物或临床上,不少人在探讨时间剂量因素对放疗疗效的影响。尽管还没有明确的结论,但也积累了一些经验。根据临床治疗的观察,对一些经过常规(每周治疗五天)治疗四周,局部肿瘤仍明显存在的鼻咽癌患者,我们改用每周两次加大剂量治疗后,肿瘤明显缩小。本文用实验动物初步探讨两种时间剂量因素对疗效的作用。
There are many factors that determine the success or failure of radiotherapy for tumors. For many years, many people have investigated the effects of time and dose factors on the efficacy of radiotherapy, both in laboratory animals and clinically. Although there are no clear conclusions, some experience has been accumulated. According to the observation of clinical treatment, for patients with nasopharyngeal carcinoma who have been treated with conventional (five days per week) treatment and local tumors are still clearly present, we have switched to twice-weekly escalating doses to reduce the tumor size. This article used experimental animals to explore the effect of two time dose factors on the efficacy.
