直至本世纪中叶,临床放射治疗还只是一种技艺,不成其为一门科学。其临床实践还是基于二十年代和三十年代的概念以及对不合理放疗后的肿瘤效应的观察经验来施行。当时流行的概念是:①基于“悉皆悉无律”认定制癌剂量与组织学类型有关。②强调用手术或放疗单一方法治疗肿瘤。③那时外科医生强调“Cancerwise”方法主张根治手术。④不采用术后选择性放疗,因为据信必须等到肿瘤复发方可有地放矢地照射。 1895年射线问世至1945年第二次世界大战结束半个世纪当中放疗仅处于放射肿瘤学
Until the middle of this century, clinical radiation therapy was only a skill and it was not a science. Its clinical practice is based on the concept of the 1920s and 1930s and the observation of the tumor effects after irrational radiotherapy. The concept that was popular at the time was: 1 Based on the fact that “all knowledge is not known,” the cancer dose determined to be related to the histological type. 2 emphasize the use of surgical or radiotherapy single method of treatment of tumors. 3 At that time the surgeon emphasized that the “Cancerwise” method advocated radical surgery. 4 Do not use postoperative selective radiotherapy because it is believed that it must wait until the tumor recurs before it can be properly targeted. The radiation came out in 1895 to the end of the Second World War in 1945. During the half century, radiotherapy was only on radiation oncology.
