ABSTRACT
Brachytherapy plays an important role in radical radiotherapy of cervical cancer. At present, most hospitals in China use high-dose-ate brachytherapy, which irradiatevolume by simulating line source with a single approximate point source. Therefore, the dwell positions and dwell times can be optimized appropriately. However, due to various reasons, the initial state of the optimization plan must start from the standard loading pattern, and ensure that the optimized plan basically maintains the pear-shaped dose distribution. This paper introduces the standard loading pattern of intracavitary brachytherapy and intracavitary combined interstitial brachytherapy for cervical cancer through literature review, and expounds the planning optimization model and the constraints in the optimization process, to provide important reference for the planning of brachytherapy for cervical cancer.
