目的观察中上段中晚期局限性食管癌术前放疗的疗效。方法对116例中上段中晚期局限性食管癌患者,随机分为单纯手术组和术前放疗组,各58例。术前放疗组行6mV直线加速器照射,剂量40gy/4周,放疗后2～4周手术。结果两组手术切除率、1年生存率、3年生存率术前放疗组均高于单纯手术组。结论术前放疗能提高中上段中晚期局限性食管癌的手术切除率和远期生存率。
Objective To observe the effect of preoperative radiotherapy in the middle and advanced stage of localized esophageal cancer. Methods One hundred and sixty-six patients with upper and middle stage advanced esophageal cancer were randomly divided into simple operation group and preoperative radiotherapy group, 58 cases each. Preoperative radiotherapy group line 6mV linear accelerator irradiation, dose 40gy / 4 weeks, 2 to 4 weeks after radiotherapy surgery. Results The resection rate, 1-year survival rate and 3-year survival rate of the two groups were significantly higher than that of the surgery alone group. Conclusions Preoperative radiotherapy can improve the surgical resection rate and long-term survival rate of the middle and late advanced esophageal cancer.
