目的探讨三维适形放疗技术对老年食管癌患者的远期疗效。方法回顾性分析2007年1月-2009年1月在我院接受三维适形放疗的50例老年食管癌患者的临床资料,并与同期行常规分割放射治疗的50例老年食管癌患者作比较,分析局部控制率、生存率及毒副反应。结果适形组1、3、5年局部控制率和生存率明显高于常规组(P<0.05),治疗毒副反应发生率相似。结论三维适形放疗技术治疗老年食管癌患者安全、有效,可以有效提高远期疗效,延长患者生存期。
Objective To investigate the long-term effect of three-dimensional conformal radiotherapy on elderly patients with esophageal cancer. Methods The clinical data of 50 elderly esophageal cancer patients undergoing three-dimensional conformal radiotherapy in our hospital from January 2007 to January 2009 were retrospectively analyzed and compared with 50 elderly patients with esophageal cancer who underwent routine fractionated radiotherapy in the same period. Analysis of local control rate, survival rate and toxicity. Results The local control rate and survival rate in conformal group at 1, 3 and 5 years were significantly higher than those in conventional group (P <0.05). The incidence of toxic and side effects was similar. Conclusion Three-dimensional conformal radiotherapy for elderly patients with esophageal cancer is safe and effective, which can effectively improve the long-term efficacy and prolong the survival of patients.
