目的：在女性乳房的外束照射过程中使用定位和固定技术既耗时又昂贵。目前可用的标准化定位设备还不够。为此，我们设计了一种新型的、通用的硬质泡沫定位支撑垫，供乳房照射期间使用，并在前瞻性研究中测试了其临床实用性。 方法和材料：55 名女性乳腺癌患者在乳房保守手术后接受辅助放疗，接受不固定（n = 27）或使用定位支撑垫（n = 28）的照射。确定患者摆位所需的时间、躺卧主观舒适度以及将射野图像与模拟器图像进行比较-摆位的可重复性。结果：辐照可重复性显着提高（无定位支撑垫的平均偏差：8.4 mm，有定位支撑垫的平均偏差：6.1 mm，p < 0.001），有定位支撑垫的患者定位所需时间平均为 73 秒，无定位支撑垫为 55 秒，A 显着更高比例的患者（72%）认为有定位支撑垫的体位是愉快的，而只有 46% 的患者对没有定位支撑垫的体位感到满意。结论：我科设计的定位支撑垫对乳腺照射的质量保证做出了重大贡献。它显着提高了患者仰卧位的舒适度。与传统的定位和固定辅助工具相比，它可以快速、轻松地以低成本应用。因此，可以推荐使用它。 (C) 1998 爱思唯尔科学公司。
Purpose: The use of positioning and immobilization techniques during external beam irradiation of the female breast is time consuming and expensive. The currently available standardized positioning devices are insufficient. For this reason, we designed a new and generally useable hard foam positioning support cushion for the use during breast irradiation, and tested its clinical usefulness in a prospective study.Methods and Materials: Fifty-five female breast cancer patients receiving adjuvant radiotherapy following breast-conservative surgery were irradiated either without immobilization (n = 27) or with the positioning support cushion (n = 28). The time necessary for patient setup, the lying subjective comfort and - comparing portal images with simulator images-the reproducibility of the set up were determined.Results: Irradiation reproducibility was significantly improved (average deviation without positioning support cushion: 8.4 mm, with positioning support cushion: 6.1 mm, p < 0.001), The time required for the positioning of the patient with positioning support cushion was in average 73 s, without cushion it was 55 s, A significantly higher proportion of patients (72%) found the position with the positioning support cushion as pleasant, whereas only 46% of patients were pleased with the position without cushion.Conclusion: The positioning support cushion designed in our department makes a substantial contribution to quality assurance in breast irradiation. It significantly increases the patients' comfort in a supine position. In contrast to conventional positioning and fixation aids it may be quickly and easily applied at low costs. Therefore, its use can be recommended. (C) 1998 Elsevier Science Inc.
