Abstract

Objective: To analyze the time characteristics of the Ethos online adaptive radiotherapy (OART) process in clinical practice and provide guidance for the comprehensive optimization of each stage of adaptive radiotherapy.

Methods: The study involved 61 patients with cervical, rectal, gastric, lung, esophageal, and breast cancers who underwent Ethos OART. The mean ± standard deviation of segmental time, total time, and target volume for these patients were tracked. The time characteristics for different cancer types were evaluated, and the average time for target and organ at risk (OAR) modifications was compared with the average target volume for each cancer type.

Results: Cervical cancer born the longest total treatment time, while breast cancer had the shortest. For all cancer types except breast cancer, the modification time for target and OAR was the most time-consuming segment. The average time for target and OAR modifications aligned with the trend of the average target volume.

Conclusion: The total treatment time for various cancers ranges from 15 to 35 minutes, indicating room for improvement.

Ethos在线自适应放疗临床应用的分段时间研究及优化策略

目的：分析Ethos在线适应放疗（OART）过程在临床实践中的时间特征，为适应放疗各阶段的综合优化提供指导。方法：研究纳入61例接受Ethos OART治疗的宫颈癌、直肠癌、胃癌、肺癌、食管癌和乳腺癌患者。追踪这些患者的节段时间、总时间和靶容积的平均值±标准差。评估不同癌症类型的时间特征，并将靶和器官危险（OAR）修饰的平均时间与每种癌症类型的平均靶体积进行比较。结果：宫颈癌总治疗时间最长，乳腺癌最短。对于除乳腺癌外的所有癌症类型，靶标和OAR的修饰时间是最耗时的一段。目标和桨面调整的平均时间与平均目标体积的趋势一致。结论：各种肿瘤的总治疗时间在15 ~ 35分钟之间，有改善的空间。
