1978年9月召开的第9届胃癌放射治疗研究会上明确了胃癌复发病例放射治疗的现状和问题。 (一)放射治疗的几个问题: 1.治疗设备和照射剂量:胃癌术后复发病例放射治疗时,用~(60)钴治疗付作用大,不可能做到充分的照射;6-10 MVX线付作用少,能达到照射目的。腹壁复发与锁骨上淋巴结的转移,用高能电子线治疗可达到予期治疗的效果;对复发的胃癌术中照射是无效的。疗效比较满意的剂量一般是5000～6000拉德以上。虽照射剂量较大,但未引起明显的肠道不良反应。 2.与组织学所见的关系:探讨胃癌术后复发病例放疗的适应症与疗效,参照胃癌术前放疗组织学的疗
At the 9th Conference on Radiation Therapy for Gastric Cancer, held in September 1978, the status and problems of radiotherapy for recurrent cases of gastric cancer were clarified. (1) Several problems of radiation therapy: 1. Treatment equipment and radiation dose: When radiotherapy for recurrence of gastric cancer is performed, the use of ~(60) cobalt treatment has a large effect and it is impossible to achieve adequate irradiation; 6-10 MVX The effect of the line is small and the purpose of irradiation can be achieved. The recurrence of the abdominal wall and the metastasis of the supraclavicular lymph nodes can be achieved by high-energy electron beam treatment. The intraoperative irradiation of recurrent gastric cancer is not effective. The satisfactory dose is generally 5000 to 6000 rad. Although the irradiation dose was relatively large, no significant intestinal adverse reactions were caused. 2. Relationship with histology: Indications and efficacy of radiotherapy for postoperative recurrence of gastric cancer, with reference to the histological treatment of preoperative radiotherapy for gastric cancer
