RESUMO
Radiation therapy plays an important role in the adjuvant treatment of patients with early endometrial carcinoma. Vaginal stump is a common site of disease failure for early endometrial carcinoma patients with intermediate-high risk factors for recurrence. Compared with external beam radiotherapy, vaginal brachytherapy (VBT) can achieve comparable local control rate with fewer toxicities. In this article, research progresses upon the application of VBT in patients with early endometrial carcinoma after hysterectomy were investigated from multiple perspectives of the selection of patients, the selection of vaginal applicator, factors influencing dose distribution, image-guided adaptive brachytherapy, the design and implementation of radiotherapy regime. In addition, the application of intensity-modulated VBT and the usage of novel quality assurance equipment were also discussed.
