Abstract

Introduction

The CyberKnife® (CK) system is capable of treating localised brain lesions with the help of a 6D skull tracking system. Hair position plays a crucial role in the success of CK radiosurgery for female brain lesion patients. This study aims to compare the intrafraction offset variation in two different hair setups patients treated using CK with U-Plast thermoplastic mask, in terms of 6D skull motion assessment and positional satisfaction.

Methods

A retrospective analysis of 40 female intracranial lesion patients treated using CK stereotactic radiosurgery (SRS). Total populations of patients were divided into two groups based on their hair setup. Group A patients hair placed below the shoulder level, keeping their hair out and divided into two sections, and group B patients was positioned all their hair settled down on their head and shoulder area. 6D skull motion assessment between both hair setup and positional satisfaction was evaluated using Microsoft Excel statistical tools.

Results

The study's results indicates the six directional mean intrafractional setup errors and 3D vector displacement of translational movements of group B were recorded significantly less as compared to the group A patients. Patient satisfaction regarding hair positioning in group B was 36.9 percent greater than in group A, while overall satisfaction in group B surpassed that of group A by 48.1 percent.

Conclusion

Study findings suggests significant differences in both 6D skull motion and positional satisfaction between the two groups, These findings emphasize the importance of considering group B hair setup variations in patient setup to enhance the efficacy and patient experience of CK radiosurgery.

Implications for practice

This study emphasizes the importance of group B type hair setup protocols in female patients undergoing CK-SRS.

射波刀立体定向放射治疗女性脑病变患者两种典型发位变化的6D颅骨运动评估和位置满意度的比较研究

CyberKnife®（CK）系统能够在6D颅骨跟踪系统的帮助下治疗局部脑病变。头发位置对女性脑病变患者CK放射治疗的成功起着至关重要的作用。本研究旨在比较两种不同发型的患者在使用U-Plast热塑性口罩治疗CK时，在6D颅骨运动评估和位置满意度方面的偏移变化。方法回顾性分析40例接受CK立体定向放射治疗的女性颅内病变患者的临床资料。根据患者的发型将患者分为两组。A组患者的头发放置在肩部以下，保持头发在外面，分为两段，B组患者的头发全部落在头部和肩部。使用Microsoft Excel统计工具对头发设置和位置满意度之间的6D颅骨运动评估进行评估。结果B组患者的6个方向平均屈曲位误差和平移运动的三维矢量位移均明显小于A组。B组患者对头发定位的满意度比A组高36.9%，B组总体满意度比A组高48.1%。结论两组患者在6D颅骨运动和体位满意度上存在显著差异，强调在患者体位设置中考虑B组患者体位变化对提高CK放疗疗效和患者体验的重要性。本研究强调B组植发方案在接受CK-SRS的女性患者中的重要性。
