Modern Radiotherapy Techniques for the Treatment of Cervical Cancer

Video Transcription

Video Summary

In this video, the speaker provides an introduction to radiation therapy and discusses different sources of ionizing radiation, such as X-rays, gamma rays, and proton therapy. They explain how radiation treatment planning has evolved from 2D-based planning to 3D-based planning, and then to intensity-modulated radiation therapy (IMRT), which allows for more precise shaping of the radiation dose around the tumor. The speaker discusses the use of IMRT for cervical cancer and its potential to reduce toxicity. They also explain the use of stereotactic body radiation therapy (SBRT) for gynecological malignancies, particularly for lymph nodes in close proximity to organs at risk and for pelvic recurrences. The speaker describes different brachytherapy techniques, including the use of intracavitary applicators with interstitial components and the benefits of MR-guided brachytherapy. They discuss the results of the MR-guided brachytherapy studies, including excellent local control rates and correlations between dose and late toxicity. The speaker concludes by mentioning the EMBRACE protocol, which includes new guidelines for organ constraints aimed at reducing long-term toxicity.
