High-Dose-Rate Intracavitary Brachytherapy

HDR ICBT is often considered when radical chemoradiotherapy is required to boost the primary cervical lesion, or when residual lesions after external irradiation require local enhancement. The decision is restricted by factors such as tumor size and regression, whether the anatomy is suitable for the device, whether interstitial needles need to be combined, general condition, and previous treatment effects.
