Yuya Miyasaka(D3)

We are pleased to report that Dr. Miyasaka(D3) participated in the 61st ASTRO Annual Meeting held in Chicago, USA, from September 15 to 19, 2019. D. student, Dr. Miyasaka participated in the 61st ASTRO Annual Meeting held in Chicago, U.S.A. from September 15 to 19, 2019, and presented a paper entitled “Clinical impact of estimation rectal toxicity using deformable image registration for cervical cancer D. course, I gave a presentation entitled “Clinical impact of estimation rectal toxicity using deformable image registration for cervical cancer patients” at the Poster Q&A session. Although DIR has been widely used until now, there are very few papers that prove its clinical usefulness, and this has been an obstacle to further application of DIR in clinical practice. In the study presented here, the clinical usefulness of DIR in dose estimation of external and intracavitary irradiation for cervical cancer was verified by direct comparison between DIR and conventional methods. In recent years, ASTRO has required a 5-minute presentation in English for the poster session, so it was necessary to practice well. Thanks to the practice, we were able to successfully complete the presentation, which was a good experience for us to present our research overseas. This experience also motivated me to further develop my research and to send it out to the world.

AI, MRI Linac, and FLASH therapy were important topics in the Physics section of the conference, and I got the impression that AI is being treated more like an algorithm for some purpose than something new and special, The number of facilities that have started clinical use of MRI Linac has been steadily increasing, and its actual use was introduced. In the actual treatment field, it was reported that it still takes about one hour per treatment to perform on-line adaptive therapy. FLASH therapy is a dream-like technology that reduces adverse events by as much as 30% while maintaining the same level of tumor control. This is a dream come true. It was introduced that a device that can deliver proton beams or Linac-based electron beams is under development. I still have not fully understood the mechanism of this technology, so I would like to learn more about it from the papers that were presented at the conference.

I was able to do a little sightseeing in between the conferences, and I was able to enjoy the great city of Chicago. In particular, the view of Chicago from the Willis Tower was breathtaking.

I would like to express my sincere appreciation to everyone who supported me in various ways during my presentation.
