Abstract

Abstract:

As one of the three major treatments for cervical cancer, radiotherapy plays an important role in treating cervical cancer. In recent years, new technologies such as three-dimensional external beam radiotherapy and image-based brachytherapy have been widely used in the treatment of cervical cancer, which can increase the dose of tumor radiation while reducing the dose radiating surrounding normal tissues. In addition, the researches on the use of individualized radiotherapy guided by imaging indicators and proton therapy are also in progress. This paper presents the basic knowledge of radiotherapy for cervical cancer and the application of radiotherapy in the treatment of cervical cancer, summarizes the application of new technologies, and proposes issues that need to be emphasized in the use of new technologies, in order to guide clinical application.

Key words: Uterine cervical neoplasms, Radiotherapy, Radiotherapy, image-guided, Dose fractionation, radiation

摘要：

放射治疗作为宫颈癌三大治疗方法之一，在宫颈癌治疗中占有重要地位。近年来，三维体外照射及三维腔内照射等新技术开始广泛应用于宫颈癌治疗，这些新技术在提高肿瘤照射剂量的同时还减少了周围正常组织的受量。此外，对于以影像学指标指导个体化放射治疗、质子治疗的探索等研究也在不断进行中。本文对宫颈癌放射治疗的基本知识、放射治疗在宫颈癌治疗中的应用进展进行阐述，总结新技术的适用情况，并提出新技术使用中需注意的问题，以期指导临床应用。
