目的：探讨两种不同体位固定技术在食道癌放疗中的摆位误差。方法：随机抽取50例进入研究的食道癌放疗的患者，随机分为A、B两组：A组25例为常规单纯使用真空袋固定法；B组25例使用头颈肩网膜下拉法与脚部“U”固定法相结合的固定方法。对两种不同标记的摆位精度进行比较。结果：两组三维误差的差异有统计学意义（t=3.78，P<0.05）。结论：头颈肩网膜下拉法与脚部“U”固定法相结合的摆位精度得到了明显的提高，推荐临床使用。

Objective:To explore the setup errors of two different position fixing in radiotherapy of esophagus cancer.Method:50 cases of esophagus cancer patients with radiotherapy were randomly divided into two groups,group A 25 cases use a simple vacuum pad fixing technology,25 cases of group B use Head-neck-shoulder omentum droping Combined with the foot "U" fixed method,The setup accuracy of marked method of two groups were compared. Result:The differences on Three-dimensional setup errors were significantly(t=3.78,P<0.05).Conclusion:The positioning accuracy of Head-neck-shoulder omentum droping combined with the foot"U"fixed method in treatment of esophagus cancer is significantly improved and recommended for clinical use.
