我们自1988年12月至1990年3月采用了高剂量率后装腔内治疗食管癌,并与单纯外照射的方法做了前瞻性随机对照研究。将食管癌病人按照相同条件配对分为两组。单纯外照射(外照组):给予同中心三野照射,肿瘤量70Gy/7W。体外照射加腔内治疗组(腔内组):先行外照射,肿瘤量达40～60Gy/4～6W,休息5～7天加腔内治疗,每周一次,每次5～10Gy,组织量达10～20Gy/2F/2W。剂量参考点选在离食管中心轴
We used high-dose-rate post-installation endovascular treatment of esophageal cancer from December 1988 to March 1990 and conducted a prospective randomized controlled trial with external exposure alone. Esophageal cancer patients were divided into two groups according to the same conditions. External exposure (external illumination): Irradiated with three centers in the same contig. The tumor volume was 70 Gy/7W. Extracorporeal irradiation plus intraluminal treatment group (intraluminal group): External irradiation first, tumor volume 40-60Gy/4-6W, rest 5-7 days plus endovascular treatment, once weekly, 5-10Gy each time, tissue volume Up to 10-20 Gy/2F/2W. Dose reference points are selected from the axis of the esophagus
