日本京都大学医学部放射线医学教室阿部光幸教授于1982年4月来华访问,介绍了他于1964年以来开展术中放疗的经验。术中放疗是手术中尽可能将癌灶切除,对残余癌灶直接给予一次大剂量照射。现代化的放射治疗设备为术中放疗创造了良好条件,日本从六十年代开始以来,已有28个医院相继使用。美国自1977年起,已有Howard大学、马萨诸塞州总医院、国立癌中心、Mayo医院等使用了术中放疗。阿部教授按不同肿瘤分别介绍了具体方法。一、胃癌胃癌容易出现腹腔动脉周围淋巴结转移,手术难以彻底清扫。这个部位外照射时,小肠可能受到损伤而不能给予根治剂量。手术时切除原发灶及胃周围淋巴结,在胃肠吻合术前,将电子束限线筒直接插入腹腔,对准难以清扫的腹腔动脉周围淋巴
Professor Kurobe Abe, a professor of radiation medicine at the Kyoto University’s Department of Medicine in Japan, visited China in April 1982 to introduce his experiences in performing intraoperative radiotherapy since 1964. Intraoperative radiotherapy is to remove the lesion as much as possible during the operation, and directly give a large dose of irradiation to the residual lesion. Modern radiotherapy equipment has created favorable conditions for intraoperative radiotherapy. Since the beginning of the 1960s in Japan, 28 hospitals have been used in succession. Since 1977, the United States has used intraoperative radiotherapy at Howard University, Massachusetts General Hospital, National Cancer Center, and Mayo Hospital. Professor Abe introduced specific methods according to different tumors. First, gastric cancer and gastric cancer are prone to celiac artery lymph node metastasis, and it is difficult to completely clean the operation. When irradiated outside this area, the small intestine may be damaged and no radical dose may be given. During surgery, the primary tumor and lymph nodes around the stomach were removed. Before the gastrointestinal anastomosis, the electron beam limiting wire barrel was inserted directly into the abdominal cavity to align the difficult-to-sweep celiac artery lymph nodes.
