摘要:
目的对比分析乳腺托架联合负压真空垫和单用乳腺托架在乳腺癌改良根治术后放疗中的临床价值。方法回顾性分析2019年10月1日至 2021年9月31日在西安国际医学中心医院放疗中心行乳腺癌改良根治术后放射治疗的64例患者的临床资料，其中对照组（32例）采用乳腺托架固定体位，联合组（32例）采用乳腺托架联合负压真空垫固定体位，分别采集单次治疗前、治疗后锥形束CT扫描图像，扫描图像与CT定位图像进行骨性配准，从而得出治疗前、后的左右（X轴）、头脚（Y轴）、前后（Z轴）方向的摆位误差。比较2组的摆位治疗成功率及危及器官的受照剂量和放疗副作用的发生率。结果联合组在X、Y、Z 轴上的摆位误差分别为（2.01±1.16）mm、（2.89±1.24）mm、（2.56±1.34）mm，对照组分别为（4.35±1.60）mm、（4.91±1.21）mm、（4.05±1.82）mm，差异均具有统计学意义（P<0.05）。联合组在X、Y、Z 轴上的总体摆位成功率为90.65%，对照组为78.13%，差异有统计学意义（P<0.05）。联合组危及器官心脏的V5、V20、Dmean、Dmax分别为（3.93±1.65）Gy、（1.21±0.15）Gy、（1.68±0.32）Gy、（40.13±2.76）Gy，均低于对照组，差异有统计学意义（P<0.05）。肺的V5、V20、Dmean、Dmax分别为（6.32±1.18）Gy、（2.53±0.25）Gy、（2.62±0.55）Gy、（44.05±2.30）Gy，均低于对照组，差异有统计学意义（P<0.05）。联合组放射性肺炎发生率（3.15%）低于对照组（15.63%），差异有统计学意义（P<0.05）。结论乳腺托架联合负压真空垫在乳腺癌术后放射治疗中，具有摆位误差小、体位固定性好、危及器官受照剂量低、放疗并发症少等优势，值得临床进一步研究推广。
Abstract:
ObjectiveTo compare and analyze the clinical value of breast bracket combined with negative pressure vacuum pad and breast brace alone in radiotherapy after modified radical mastectomy for breast cancer.Methods64 patients who underwent postoperative radiation therapy for breast cancer in our hospital from October 1, 2019 to September 31, 2021 were enrolled and divided into the control group (32 patients) used breast brackets in fixed position and the experimental group (32 patients) used breast brackets combined with vacuum pads in fixed position. Cone beam CT scans were performed before and after treatment in separate intravals. The scanned images were bony with the localized images and the bony alignment between the scans and the positioning images were performed, and the positional errors in the left-right (X-axis), head-foot (Y-axis), and anterior-posterior (Z-axis) directions were obtained before and after the treatment. The positional success rate and the incidence of cardiopulmonary dose and radiotherapy side effects were compared between the two groups.ResultsThe positional errors in the X, Y and Z axes of the experimental group were（2.01±1.16）mm，（2.89±1.24）mm，（2.56±1.34）mm respectively, and the control group were （4.35±1.60）mm，（4.91±1.21）mm，（4.05±1.82）mm, respectively (P<0.05). The overall positional success rate of the experimental group and the control group were 90.65% and 78.13% (P<0.05). The irradiated doses (V5，V20，Dmean，Dmax)of the heart were （3.93±1.65）Gy，（1.21±0.15）Gy，（1.68±0.32）Gy，（40.13±2.76）Gy in experimental group, which were lower than the control group (P<0.05). The irradiated doses (V5，V20，Dmean，Dmax)of the lungs were （6.32±1.18）Gy，（2.53±0.25）Gy，（2.62±0.55）Gy，（44.05±2.30）Gy in experimental group, which were lower than the control group (P<0.05). The incidence of radiation pneumonia was 3.15% in the experimental group and 15.63% in the control group. The incidence of radiation pneumonia in the experimental group was lower than that in the control group (P<0.05).ConclusionThe application of breast bracket combined with vacuum pad in postoperative radiation therapy for breast cancer has the advantages of small positional error, good postural fixation, low cardiopulmonary irradiated dose and less radiotherapy complications, which is worthy of further clinical study and promotion.
