应用高能电子流治疗胸腔深部肿瘤的问题,尚未被大家一致的接受。虽然sehumaeher报告用55百万电子伏电子流,前后对野,大剂量分割照射的方法治疗肺癌及食道癌获得了很好的疗效,但Zatz,Esseu及KaPlau则经若干年临床实践后报告了相反的结 The use of high-energy electron flow in the treatment of deep thoracic tumors has not been unanimously accepted. Although sehumaeher reported that the use of 55-m electron-volt electron flow, front-to-back field, and high-dose fractionation methods for radiation therapy for lung cancer and esophageal cancer, had good results, Zatz, Esseu, and KaPlau reported that they had reversed their clinical practice for several years.
