Abstract

BACKGROUND

This dosimetric study aims to evaluate the dosimetric advantage of the irregular surface compensator (ISC) compared with the intensity-modulated radiotherapy (IMRT).

MATERIALS AND METHODS

Ten patients with whole breast irradiation were planned with the ISC and IMRT techniques. Six different beam directions were selected for IMRT and ISC plans. The treatment plans were evaluated with respect to planning target coverage, dose homogeneity index (DHI) and organs at risk (OARs) sparing. Monitor units (MUs) and the delivery time were analysed for treatment efficiency.

RESULTS

The ISC technique provides a better coverage of the PTV and statistically significantly better homogeneity of the dose distribution. For the ipsilateral lung and heart, ISC and IMRT techniques deliver almost the same dose in all plans. However, MU counts and delivery time were significantly lower with the IMRT technique (p < 0.05).

CONCLUSION

For breast radiotherapy, when the ISC method was compared to the IMRT method, ISC provided better dose distribution for the target.

摘要

背景

本剂量学研究旨在评估不规则表面补偿器（ISC）与调强放射治疗（IMRT）相比的剂量学优势。

材料与方法

对10例全乳照射患者采用ISC和IMRT技术进行计划制定。为IMRT和ISC计划选择六个不同的射野方向。从计划靶区覆盖、剂量均匀性指数（DHI）和危及器官（OARs）保护方面对治疗计划进行评估。分析监测单位（MUs）和照射时间以评估治疗效率。

结果

ISC技术能更好地覆盖计划靶区（PTV），且剂量分布的均匀性在统计学上显著更好。对于同侧肺和心脏，ISC和IMRT技术在所有计划中给予的剂量几乎相同。然而，IMRT技术的MU计数和照射时间显著更低（p < 0.05）。

结论

对于乳腺癌放疗，将ISC方法与IMRT方法相比时，ISC为靶区提供了更好的剂量分布。
