乳腺托架在胸部肿瘤患者放疗中的应用

Application of Breast Bracket in Radiotherapy for Patients with Thoracic Tumor

目的:探讨胸部恶性肿瘤患者放射治疗中,乳腺托架与一体式固定体架两种体位固定方式在摆位误差、摆位时间的差别。方法:选取50例需要放疗的胸部肿瘤患者,随机分为一体式固定体架组(对照组)和乳腺托架组(观察组),每组25例,分别记录患者首次摆位所需时间,通过EPID对两组患者摆位误差进行测量对比。结果:对照组患者与观察组患者平均摆位时间比较,差异具有统计学意义(P<0.001),但是两组患者摆位误差在X、Y、Z轴方向上均无统计学差异(P>0.05)。结论:乳腺托架应用于胸部肿瘤患者放射治疗能明显缩短摆位时间、提高摆位效率,并能提高患者放疗舒适度。

Objective:To investigate the difference in positioning error and positioning time between the breast bracket and the integrated fixed frame in radiotherapy for patients with breast malignant tumors.Method:Select 50 patients with thoracic tumors requiring radiotherapy and randomly divide them into one-piece fixed frame group(control group)and breast bracket group(observation group),25 cases in each group,and record the time required for the first placement of the patients.The set-up error of the two groups of patients was measured and compared by EPID.Results:Comparing the average setting time of patients in the control group and the observation group,the difference was statistically significant(P<0.001),but there was no statistical difference in the setting errors of the two groups of patients in the X,Y,and Z axis directions(P>0.05).Conclusion:The application of breast bracket to radiotherapy for patients with thoracic tumors can significantly shorten the set-up time,increase the set-up efficiency,and improve the patient's radiotherapy comfort.
