任何部位的肿瘤皆可由超高压照射达到足够之肿瘤剂量,但如病变接近放射敏感器官则不宜采用外照射,而局部晚期癌又往往不能彻底切除,故此,作者采用术中放疗,即手术切除病变后在术中做一次大剂量照射。照射野在直视下划定,并可将敏感器官置于射野之外,故能安全而准确地给肿瘤以高剂量而不损伤正常组织。作者采用~(60)钴或电子射线,一次照射剂量鳞癌3000～3500 rad、腺癌为3000～4000 rad。本文报告术中照射用于胃癌等多种肿瘤的临床结果。胃癌术中照射在切除肿瘤之后尚未吻合之前进行,其治疗3组。第一组14例皆有腹腔或肝转移,照射之目的在于决定有效剂量。观察表明一次照射 Any part of the tumor can be achieved by ultra-high pressure irradiation to achieve adequate tumor dose, but if the lesion is close to radiation-sensitive organs should not use external radiation, and locally advanced cancer often can not be completely removed, so the authors use intraoperative radiotherapy, surgical resection of lesions After a large dose of radiation in the surgery. The radiation field is demarcated under direct vision, and the sensitive organs can be placed outside the shooting field. Therefore, the tumor can be safely and accurately given a high dose without damaging the normal tissue. The authors used ~(60)cobalt or electron beam, one dose of squamous cell carcinoma 3000 ~ 3500 rad, adenocarcinoma 3000 ~ 4000 rad. This article reports the clinical results of intraoperative irradiation for many types of cancer such as gastric cancer. The intraoperative irradiation of gastric cancer was performed before the anastomosis was performed after the tumor was removed. The treatment was performed in three groups. The first group of 14 cases all had abdominal or liver metastases. The purpose of the irradiation was to determine the effective dose. Observe that one shot
