直肠癌手术治疗的疗效尚很不满意,所以近年来不少作者研究术前放疗加手术的综合治疗方法,可以提高五年生存率10％～15％,并可降低局部复发率,我院自1972年至1977年12月共80例直肠癌作术前放疗,但本组病例系选择性,病期偏晚较多,放疗前均经病理证实,随诊五年以上的共38例。治疗方法;术前放疗采用高能射线(电子加速器或~(60)Co),照射范围上自骶1,下至肛门缘,二侧达盆壁,前后二野对穿照射。肿瘤量3000～4000rad/3-4周,放疗结束后休息10天
The curative effect of surgical treatment of rectal cancer is still unsatisfactory, so in recent years many authors study preoperative radiotherapy and surgery combined treatment, can improve the five-year survival rate of 10% to 15%, and can reduce the local recurrence rate, our hospital since From 1972 to December 1977, a total of 80 cases of rectal cancer were treated with preoperative radiotherapy. However, this group of patients was selective and had a more advanced stage of disease. All cases were confirmed by pathology before radiotherapy and 38 cases were followed up for more than five years. Treatment methods; preoperative radiotherapy using high-energy radiation (electron accelerator or ~ (60) Co), the scope of irradiation from the fistula 1, down to the anal margin, two sides of the basin wall, before and after the two fields to wear radiation. Tumor volume 3000～4000rad/3-4 weeks, rest 10 days after radiotherapy
