摘要

在保乳手术(BCS)后采用辅助放射治疗(RT)时,对于确诊为左侧乳腺癌的患者来说,必须谨慎对待辐射照射到心脏的风险。深吸气憋气(DIBH)是一种调节患者呼吸和扩张胸壁的技术,可增加治疗区域与周围器官之间的距离,从而为心脏提供保护。带有激光测距传感器(LDS)的自我监测系统不附着在病人身上,可以监测呼吸,从而确保 DIBH 的可重复性。实验以 11 名临床左侧乳腺癌患者为一组,分别进行了自我监测或不进行自我监测。不进行自我监测时,无论 DIBH 基线如何,患者都表现出呼吸倾向,没有证据表明患者有纠正错误的倾向。第一次和第二次 DIBH 之间的平均距离误差分别为 3.78 毫米和 3.95 毫米,平均距离误差总体呈上升趋势。在进行自我监测时,有根据 DIBH 基线纠正错误的趋势。第一个 DIBH 和第二个 DIBH 之间的平均距离误差分别为 2.02 毫米和 1.98 毫米,相对较小。带有 LDS 的自我监测系统有助于在整个治疗期间保持 DIBH,从而确保治疗效果与规定的治疗方案保持一致。此外,LDS 可以测量绝对距离,提高了 DIBH 患者定位的准确性。

Improving the reproducibility and accuracy of DIBH with a laser distance sensor self-monitoring system in left breast cancer patients

Improving the reproducibility and accuracy of DIBH with a laser distance sensor self-monitoring system in left breast cancer patients

When adjuvant radiation therapy (RT) is employed following breast-conserving surgery (BCS), it is imperative to exercise caution regarding the risk of radiation exposure to the heart in patients diagnosed with left-sided breast cancer. Deep-inspiration breath-hold (DIBH) is a technique that regulates the patient’s breathing and expands the chest wall to increase the distance between the treatment area and surrounding organs, thereby providing protection for the heart. The self-monitoring system with a laser distance sensor (LDS) is not attached to the patient’s body and allows for the monitoring of respiration, thereby ensuring the reproducibility of DIBH. The experiment was conducted on 11 clinical left-sided breast cancer patients per group with or without self-monitoring. When self-monitoring was not performed, patients demonstrated a tendency to breathe regardless of the DIBH baseline, and there was no evidence of any tendency to correct errors. The mean distance error between the first and second DIBH was 3.78 mm and 3.95 mm, respectively, with an overall tendency for the average distance error to increase. When self-monitoring was performed, there was a tendency to correct errors according to the DIBH baseline. The average distance error between the first DIBH and the second DIBH was 2.02 mm and 1.98 mm, respectively, which was relatively small. The self-monitoring system with LDS helps to maintain the DIBH throughout the treatment period, thereby ensuring that treatment effects are consistent with the prescribed treatment plan can be expected. Furthermore, LDS, which can measure absolute distance, enhances the accuracy of patient positioning for DIBH.
