| Popis: | Precise radiotherapy plays an important role in the comprehensive multidisciplinary therapy of rectal cancer.The mainstream technology is the intensity modulated radiation therapy(IMRT).The technique of repetitive body positioning and the filling of the bladder and rectum are the important factors influencing the accuracy and efficacy of radiotherapy for rectal cancer.The quality of life for patients with rectal cancer is highly affected by side effects associated with radiotherapy.The application of precise positioning technique and image guided radiotherapy(IGRT) can significantly contribute to the accurate delivery of radiotherapy to the region of rectal cancer to improve the local tumor control and reduce unnecessary exposure of normal tissues to irradiation.In this paper,the clinical application of precise positioning technique and the improvement of accurate delivery of radiotherapy are comprehensively reviewed. |
