三维适形放疗联合多西紫杉醇化疗治疗食管癌的临床观察

目的:评价三维适形放疗联合多西紫杉醇化疗治疗食管癌的临床疗效和安全性。方法:32例不能手术或拒绝手术的中晚期食管癌患者根据入选标准随机分成同期放化疗(治疗组)和单纯三维适形放疗(对照组),每组16例,治疗组在放疗的同时给予多西紫杉醇20-30mg/m2静脉滴注,每周1次,连续6周,在放疗第一天同时进行。两组放疗方法相同,均采用直线加速器6MVX线,2Gy/次,5次/每周。照射总剂量54-64Gy,采用X线和CT检查比较两组近期疗效,并且比较两组间不良反应的差别。结果:同期放化疗组与单纯放疗组完全缓解率(CR)分别为56.3%和37.5%,有效率(CR+PR)分别为87.5%和56.3%。同期放化疗组不良反应尤其是放射性食管炎,及Ⅰ、Ⅱ度骨髓抑制较对照组大,但经处理后均能顺利完成治疗。结论:三维适形放疗联合多西紫杉醇化疗较单纯放疗组疗效好,可提高中晚期食管癌的近期有效率,不良反应患者能耐受。

Effect of three dimensional conformal radiotherapy combined with docetaxel in treatment of patients with esophageal carcinoma

Objective:To evaluate the clinical efficacy and safely of concurrent three dimensional conformal radiotherapy combined with docetaxel in treatment of patients with esophageal carcinoma.Methods: Thirty two 32 patients with locally advanced esophageal cancer were randomly divided into concurrent chemoradiotherapy group(16 patients) and radiotherapy alone group(14 patients).Radiotherapy was the same in two groups,and was given in 2Gy perfraction,5 fractions perweek with a dose of 54 to 64 Gy.Docetaxel was give...
