胃癌手术治疗的五年生存率约为40%。沿胃左动脉和肝总动脉、腹主动脉周围的淋巴结的转移灶,靠手术的办法不可能根除。因为腺癌对放射线抗拒,并且外照射可能引起肠损伤,所以放疗对胃癌治疗没有起重要作用。为了克服外科和放疗的局限性,作者使用了“术中放疗”的方法,综合治疗了38例患者。最初的术中放疗是用的~(60)钴,病人在全麻下用担架从手术室抬到放射治疗室。以后改用电子感应加速器,就在加速器治疗室进行手术。当病人手术中适合放疗时,
The five-year survival rate for surgical treatment of gastric cancer is about 40%. Metastases around the left gastric artery and the common hepatic artery and lymph nodes around the abdominal aorta cannot be eradicated by surgery. Because adenocarcinoma is resistant to radiation and external radiation may cause intestinal damage, radiotherapy does not play an important role in the treatment of gastric cancer. In order to overcome the limitations of surgery and radiotherapy, the author used the “intraoperative radiotherapy” method to treat 38 patients in a comprehensive manner. The initial intraoperative radiotherapy was performed with ~(60) cobalt. The patient was taken from the operating room to the radiation therapy room on a stretcher under general anesthesia. Later, he used an electronic induction accelerator to perform surgery in an accelerator treatment room. When the patient is suitable for radiotherapy during surgery,
