图像引导宫颈癌体外自适应放疗的剂量学研究
Dosimetric study of adaptive external beam radiotherapy for cervical carcinoma
摘要
Abstract
6 patients with cervical carcinoma treated by the SIEMENS’s Artiste received totally 18 CT scans every 8 fractions, then we replanned and obtained the three groups named by IMRT, ART1 and ART2 based on these im-ages to compare these plans’ measure indexes of dosimetry and position. The average volume of CTV reduced dur-ing the course of treatment, the dose of CTV in the three groups was similar, and there was no significant differ-ence. Bladder and rectum’s positions changed a lot, especially in the superior and inferior directions, and the do-ses of these two organs reduced significantly (P < 0. 05) at three dose levels (V40 , V45 and V50 ). The results show that the adaptive external beam radiotherapy for cervical carcinoma can adjust treatment planning depending on the feedback of scanning images, thus may not bring significant changes in targets, while on the other hand, still play a positive role in the protection of the organs at risk.关键词
