发泡胶用于头颈部肿瘤头颈肩体位固定放疗的临床研究

摘要

Objective To compare and analyze the effectiveness of head and neck cancer radiotherapy using foam fixing technology and technique of immobilization compared the clinical routine.Methods Approved by the ethics committee of Ganzhou Cancer Hospital a retrospective review of 67 patients with head and neck cancer analysis of menstrual the hospital diagnosed cases, according to the head and shoulder posturefixed position in different ways, randomly divided into foamfixation group (35 cases) and conventionalfixed pillow group (32 cases). Fixed group with fixation of styrofoam foam, while the conventional group was treated with conventionalfixed pillow pillow and the neck shoulderfilm technology. After the end of radiotherapy, observation and analysis of two groups of patients in radiotherapy for thefirst time, half a month after, last time when the average position during radiotherapy of X axis, Y axis and Z axis position error and the error of the placement of radiotherapy.Results (1) Group and the conventionalfixedfixed foam pillow for thefirst time in radiotherapy group in the difference between Y and Z axis, X axis, was not statistically significant; (2) Foamfixed group and the conventionalfixed pillow group in half a month radiotherapy difference in the Y and Z axis, X axis, have statistical significance (P<0.05); (3) Group and the conventionalfixedfixed foam pillow group in the last radiation difference in the Y and Z axis, X axis, were very significant (P<0.01); (4) The difference of styrofoamfixed group and the conventional group average position in the whole pillow during radiotherapy the placement errors were statistically significant (P<0.05).Conclusion The technique offixedfixed foam technology compared to the traditional radiotherapyfixation method can provide more comfortable, more conformal, good repeatability for patients with head and neck cancer, the clinical application of this method, it will make more patients benefit.%目的：比较并分析头颈部肿瘤放疗运用发泡胶固定技术与常规体位固定技术相比的临床有效性。方法经赣州市肿瘤医院伦理委员会认可，回顾性分析经本院确诊的头颈部肿瘤患者67例，按照头颈肩体位固定体位方式的不同，随机分为发泡胶固定组（n=35）与常规固定枕组（n=32）。发泡胶固定组采用发泡胶固定技术，而常规固定枕组采用采用常规枕和头颈肩膜技术。放疗结束后，观察并分析2组患者在首次放疗时、半个月放疗时、最后一次放疗时在X轴、Y轴和Z轴上的体位摆放误差以及整个放疗期间的平均体位摆放误差。结果（1）发泡胶固定组与常规固定枕组在首次放疗时在X轴、Y轴和Z轴上的差异无统计学意义；（2）发泡胶固定组与常规固定枕组在半个月放疗时在X轴、Y轴和Z轴上的差异均有统计学意义（P<0.05）；（3）发泡胶固定组与常规固定枕组在最后一次放疗时在X轴、Y轴和Z轴上的差异均具有统计学意义（P<0.01）；（4）发泡胶固定组与常规固定枕组在整个放疗期间的平均体位摆放误差的差异均具有统计学意义（P<0.05）。结论发泡胶固定技术相比于传统的固定技术能为头颈部肿瘤患者提供更舒适、更适形、重复性好的放疗体位固定方法，随着该方法的临床应用，必将会使更多的患者受益。
