Video Summary

In the video, the presenter discusses the transition from 2D radiotherapy to 3D brachytherapy in the treatment of cervical cancer at Queen Mary Hospital. With 2D radiotherapy, there were limitations in accurately visualizing the tumor and delivering precise doses to target areas while sparing surrounding organs. The introduction of 3D image-guided brachytherapy allowed for better visualization of the tumor using MRI or CT scans and precise targeting of high radiation doses to the tumor volume. The presenter explains the process of pre-brachytherapy preparation, applicator insertion, CT scans, and dose calculation. The presenter also shares local data from 135 patients treated at Queen Mary Hospital, showing good local control and overall survival rates. The main adverse effect observed was uterine perforation, which was mostly minor and self-healing. The presenter concludes by emphasizing the importance of practice and collaboration among the healthcare team.
