Dear TASTRO members and JASTRO friends: It's our great honor to host the 4th annual Taiwan-Japan Radiation Oncology Symposium. The theme of the conference this year is "High Precision Better Selection". During this conference, we have excellent speakers from Taiwan and Japan to present their latest researches. I hope the conference provides a platform to exchange radiation oncology related knowledge between Taiwan and Japan. I am also deeply grateful for all of our guests from Japan who brought their lectures and study results to us. I believe that through the effort of both Japan and Taiwan enables such meaningful event to continue, and become the best amongst all the radiation oncology conferences.

  I believe that today's symposium will provide you with more information and inter-hospital opportunities for cross-border cooperation. I wish the conference great success and wish you all good health and a pleasant stay in Taiwan.
