摘要 目的:探讨周剂量紫杉醇同步后程加速超分割放疗对食管癌的临床疗效、生存质量和毒副反应。方法:放疗采用6MVX线外照射,前2/3程常规放射治疗2Gy/次,每日一次,共40次,后1/3疗程改用加速超分割放射治疗,1.5 Gy/次,每日2次,间隔6小时,全疗程总剂量共66~70 Gy;化疗采用周剂量紫杉醇全身用药方案,60mg静脉滴注,每周一放疗前给药1次,共6次,用药前给予预处理。结果:全组27例患者中,完全缓解(CR)3例,部分缓解(PR)16例,稳定(SD)5例,进展(PD)3例,总有效率(CR+PR)为70.3%。毒性反应主要是白细胞减少,III-IV级骨髓抑制40.7%,一年生存率为62.9%。结论:周剂量紫杉醇同步后程加速超分割放疗治疗食管癌,可提高疗效,延长生存期,而不降低生存质量,但急性骨髓抑制较重,值得进一步研究。
