摘　　要：目的探讨真空垫联合头颈肩膜体位固定对颈上段食管癌放疗患者临床疗效及摆位误差的影响。方法选取2018年11月至2020年12月在赣州市肿瘤医院受放疗治疗的84例颈上段食管癌患者作为研究对象,按照随机数字表法分为对照组与观察组,每组42例。对照组采取真空垫体位固定,观察组采取真空垫联合头颈肩膜体位固定。比较两组临床疗效、体位摆放误差、摆位时间、摆位重复性及摆位误差率。结果观察组治疗总有效率为95.24%,高于对照组的66.67%,差异有统计学意义(P<0.05)。两组X轴摆位误差比较差异无统计学意义;观察组Y轴、Z轴和三维方向摆位误差均小于对照组,差异有统计学意义(P<0.05)。观察组摆位时间短于对照组,差异有统计学意义(P<0.05)。两组X轴≥3 mm的摆位误差率比较差异无统计学意义;观察组Y轴、Z轴≥3 mm的误差率均低于对照组,差异有统计学意义(P<0.05)。结论颈上段食管癌放疗患者应用真空垫联合头颈肩膜体位固定,可有效提高临床疗效,减少摆位误差,缩短体位摆放时间。Objective To investigate the effect of vacuum pad combined with head,neck and shoulder membrane position fixation on the clinical efficacy and positioning error of patients with upper cervical esophageal cancer radiotherapy.Methods A total of 84 patients with upper cervical esophageal cancer who received radiotherapy in Ganzhou Cancer Hospital from November 2018 to December 2020 were selected as the study subjects,and they were divided into the control group and the observation group according to the random number table method,with 42 cases in each group.The control group was fixed with vacuum pad,and the observation group was fixed with vacuum pad combined with head,neck and shoulder membrane.The clinical efficacy,positioning error,positioning time and placement error rate were compared between the two groups.Results The total effective rate in the observation group was 95.24%,which was higher than 66.67%in the control group,and the differences were statistically significant(P<0.05).There was no significant difference in X-axis positioning error between the two groups;the error of Y-axis,Z-axis and three-dimensional orientation in the observation group were smaller than those in the control group,and the differences were statistically significant(P<0.05).The placement time in the observation group was shorter than that in the control group,and the difference was statistically significant(P<0.05).There was no significant difference in the placement error rate of X axis≥3 mm between the two groups;the error rates of Y-axis and Z-axis≥3 mm in the observation group were lower than those in the control group,and the differences were statistically significant(P<0.05).Conclusion The application of vacuum pads combined with head,neck and shoulder membrane fixation in radiotherapy for patients with upper cervical esophageal cancer can effectively improve the clinical efficacy,reduce positioning errors,shorten the positioning time.
