鼻咽癌调强放疗计划十分复杂,计划质量通常与治疗剂量师的经验密切相关。本研究纳入了10例不同分期的鼻咽癌患者,基于Pinnacle3 9.2治疗计划系统脚本,运用计算机程序设置计划的基本参数、目标参数等,最终自动完成鼻咽癌调强放疗计划。然后,对自动和手动调强放疗计划进行统计学比较和临床评估。结果显示两种计划中大多数靶区和危及器官剂量学参数的差异无统计学意义。本文所述的鼻咽癌自动调强放疗计划能够满足临床放疗要求,显著减少计划时间,同时避免因为经验不足等人为因素对计划质量造成的影响。
The schedule of IMRT is very complicated, and the quality of the plan is usually closely related to the experience of the dosing therapist. This study included 10 patients with different stages of nasopharyngeal carcinoma. Based on the Pinnacle3 9.2 treatment planning system script, the computer program was used to set the basic parameters of the program, the target parameters and so on, and finally the IMRT schedule was completed automatically. Then, a statistical comparison and a clinical evaluation of the automatic and manual IMRT plans were performed. The results showed that there was no significant difference between the dosimetry parameters of most of the target areas and the organs at risk in the two plans. The described schedule of autoranging of NPC radiation therapy meets the requirements of clinical radiotherapy, significantly reduces the planning time, and avoids the impact of human factors on the planning quality due to lack of experience.
