目的探讨体部伽玛刀治疗肩颈部肿瘤中不同体位固定方法的可行性。方法肩颈部肿瘤患者77例,分别采用负压袋联合记忆模分体体位固定(A组)和负压袋一次成型整体体位固定(B组)两种方法,测量激光灯十字线与体表十字线的误差。结果 A组移动偏差>3 mm,B组移动偏差均<1.5 mm,两组差异统计学意义(P<0.05)。结论伽玛刀治疗肩颈部肿瘤患者宜采用负压袋一次成型整体体位固定方法。
Objective To explore the feasibility of body gamma knife in the treatment of different positions in shoulder and neck cancer. Methods Totally 77 patients with shoulder and neck cancer were treated with negative pressure bag combined with memory module fixation (group A) and negative pressure bag formation (group B) Cross-line error. Results The moving deviation of group A was> 3 mm, and the moving deviation of group B was less than 1.5 mm (P <0.05). Conclusion Gamma knife treatment of patients with shoulder and neck cancer should adopt a negative pressure bag forming a total body positioning method.
