【摘要】：分析乳腺癌放射治疗体位固定技术的改进方法。依据完全随机分组法将我院收治的115例行乳腺癌保乳术后调强放疗患者分为2组,对照组57例行单纯乳腺托架固定,研究组58例行楔形真空袋、直肠癌体架与热塑体膜联合固定,比较2组的体位固定效果。研究组腹背、头脚、左右3个摆位方向的误差[(2.02±0.13)mm、(2.30±0.41)mm、(2.11±0.35)mm]明显小于对照组[(3.25±0.92)mm、(3.88±0.94)mm、(3.92±0.96)mm],两组差异有统计学意义(P0.05)。通过改进体位固定技术,可缩小患者的摆位误差,提高整体摆位的准确性。
[Abstract]:To analyze the improved technique of position fixation for breast cancer radiotherapy, 115 breast cancer patients treated by IMRT were divided into two groups, 57 patients in control group were treated with simple mammary gland bracket fixation, and 115 patients were treated with IMRT after breast conserving operation in our hospital, and 57 patients in control group were treated with simple breast carrier fixation. In the study group, 58 cases were treated with wedge-shaped vacuum bag, rectal cancer frame and thermoplastic membrane were fixed together to compare the effect of postural fixation in the two groups. The error of the left and right three pendulum directions [2.02 卤0.13mm ~ 2.11 卤0.35mm] was significantly lower than that of the control group [3.25 卤0.92 卤0.96mm]. The difference between the two groups was statistically significant (P0.055.With the improvement of position fixation technique, the accuracy of the whole pendulum position could be reduced and the accuracy of the whole pendulum position could be improved.
