摘要
目的 观察后程加速超分割放射治疗食管癌的临床疗效。方法 将30 例中段食管鳞癌患者随机分为常规放疗组( A 组) 和后程加速超分割组( B 组) ,各15 例,均用60 Coγ射线照射。 A 组照射2 G Y/ 次,5 次/ 周,总量为68 G Y/6 ~7 周。 B 组前4 周照射同 A 组,第5 周开始1 .5 G Y/ 次,2 次/ 日,间隔6 小时,总量为68 G Y/5 ~6 周。结果 局控率: A 组93 .3 % (14/15) , B 组93 .3 % (14/15) ;两组1 、2 、3 年生存率分别为33 .33 % (5/15) 、0(0/15) 、0(0/15) 和80 % (13/15) 、46 .66 % (7/15) 、13 .33 %(2/15) 。结论 后程加速超分割放疗优于常规放疗。
Objectives To observate the effect of the late course accelerated hyper fraction radiation on esophageal carcinoma.Methods 30 patients were rndomly divided into conventional fraction radiation (CFR) group (15 patients) and late course hyper fraction radiation (LCHR) group (15 patients).Patients in CFR received 2GY/per fraction,5 fractions/per week with the total doses of 68GY/6~7 weeks.Patients in LCHR received 1.5GY/per fraction,two fractions per day with 6 hours terval afte 4 weeks of conventional fraction radiation,total doses of 68GY/5~6 weeks.Results The local control rates were 93.33% in both groups.The 1,2,3-year survival rates were 33.33%(5/15),0(0/15),0(0/15) in CFR group and 80%(13/15),46.66%(7/15),13.33%(2/15) in LCHR group.Conclusions Late course hyper fraction accelerated radiation are better than conventional fraction radiation.
