摘要 目的 探讨同期应用顺铂能否提高后程加速超分割 (后超 )放射治疗食管癌的疗效。方法 对符合入组条件的 81例病例 ,随机分为后超组 41例 [常规分割 30Gy +加速超分割 (1.5Gy/次、2次 /d) 30Gy]和综合组 40例 [在后超组基础上静脉输注顺铂 (2 0mg/d、连用 5d为 1周期、分别在第 1、4周实施 )共 2个周期 ]。结果 综合组和后超组的 1、3年生存率分别为 80 .0 %、73.2 %和 40 .0 %、34 .2 % ,但无统计学差异。肿瘤局限在食管壁的病例加用顺铂后生存率提高 ,综合组和后超组的 3年生存率分别为 6 6 .7%、2 5 .0 % (P <0 .0 5 ) ;早、晚期放射反应综合组较后超组高 ,综合组有 3例顽固性咽下疼痛 ,反复发作 3个月以上。结论 后程加速超分割放射治疗加用顺铂未能明显提高食管癌放射治疗的生存率 ,但对侵润局限在食管壁的病例能明显提高 3年生存率。 Objective To assess the effects of combined late course accelerated hyperfractionation radiotherapy (LAHR) and cisplatin in treating esophageal cancer. Methods From March to November 1997, 81 eligible esophageal cancer patients were randomized into two groups:41 patients in the LAHR group who first recevied 30 Gy by routine fractionation,followed by 30 Gy, 1.5 Gy twice daily, five days per week and 40 patients in the combined goup who, in addition to the LAHR, receive two cycles of cisplatin infusion,20 mg/d for five consecutive days as one cycle in the first and fourth weeks.Results The 1- and 3-year survival rates of the combined and LAHR groups were 80.0%,73.2% and 40.0%,34.2% though without statistical significance (P>0.05). The 3-year suvival rates of patients whose lesions were confined to the esophageal wall were 66.7% in the combined group and 25.0% in the LAHR group (P<0.05). There were higher incidence of the early and late radiation side-effects in the combined group among whom three patients experienced recurrent but persistant pain upon degglutition which lasted for more than three months.Conclusion Notwithstanding the failure of combined cisplatin and late course accelerated hyperfractionation radiotherapy in raising the survival over the latter method alone,the former is able to obviously improve the 3-year survival rate of esophageal cancers which are confined within esophageal wall.
