Abstract

Objective: Automatic planning is a commonly used alternative to manual planning. This study evaluated the clinical performance of automatic plans available in commercial treatment planning systems for nasopharyngeal carcinoma (NPC) treatment by comparing automatic planning with manual planning.

Methods: A total of 14 patients with nasopharyngeal carcinoma were enrolled in the study. For each patient, three different sets of clinical goals were used to generate three hybrid automatic plans based on 3D dose distribution prediction and three automatic plans based on script, respectively, which were compared with the manual plans used in clinic.

Results: The dose coverage performance of the automatic planning based on 3D dose distribution prediction on the planning target volume (PTV) was comparable to that of the manual planning. Automatic planning based on 3D dose prediction achieved the level of manual planning in most organs at risk. However, automatic planning based on scripts did not perform well in the prediction of some organs at risk, especially the parotid gland.

Conclusion: The hybrid automatic plan based on 3D dose distribution prediction can reach the level of manual planning and have good robustness with the change of clinical objective.

鼻咽癌混合自动治疗方案临床实用性评价

目的：自动计划是手动计划的常用替代方案。本研究通过比较自动规划和手动规划，评估了商业治疗规划系统中用于鼻咽癌治疗的自动规划的临床表现：方法：共有 14 名鼻咽癌患者参与了研究。对每名患者使用三套不同的临床目标，分别生成三个基于三维剂量分布预测的混合自动计划和三个基于脚本的自动计划，并与临床使用的手动计划进行比较：结果：基于三维剂量分布预测的自动计划在计划靶体积（PTV）上的剂量覆盖性能与手动计划相当。基于三维剂量预测的自动计划在大多数危险器官上达到了人工计划的水平。然而，基于脚本的自动计划在某些危险器官的预测上表现不佳，尤其是腮腺：结论：基于三维剂量分布预测的混合自动计划可以达到人工计划的水平，并且随着临床目标的变化具有良好的鲁棒性。
