Intra-operative radiotherapy (IOR) was performed for the treatment of 101 patients with gastric cancer. Doses of 28 to 35 Gy with electron beams were delivered during the surgical procedure to tumour beds, high risk lymphnodes and/or remaining cancer nests after gastrectomy. Five-year survival rates were 87.2% for patients with Stage I disease, 83.5% for Stage II, 62.3% for Stage III and 14.7% for Stage IV. Compared with the data on 110 patients treated by surgery alone, IOR has yielded better results in patients with locally advanced disease. Based on these results, indications of IOR for gastric cancer were discussed.
对101例胃癌患者实施了术中放疗（IOR）。在手术过程中，使用电子束对肿瘤床、高危淋巴结和/或胃切除术后残留的癌巢给予28至35 Gy的剂量。I期疾病患者的5年生存率为87.2%，II期为83.5%，III期为62.3%，IV期为14.7%。与110例仅接受手术治疗的患者的数据相比，术中放疗在局部晚期疾病患者中取得了更好的效果。基于这些结果，对胃癌术中放疗的适应证进行了讨论。
