These days, artificial intelligence is a popular topic. Young doctors don't apply for pathology, because they worry to lose their job in the near future. As a result, we already don't have enough pathologists, and it will make a big problem in the near future. You mentioned 2 mm section interval and immunohistostaining for lymphatic invasion. Enough time is required for pathologists to examine all the slides carefully. In my opinion, minimum time for pathologic examination can be a new quality indicator of ESD, and it should be mentioned in the domestic and international guideline. What's your opinion on that?

Magnified view shows an irregular vascular pattern and an avascular area can be seen partially. Surface pattern also shows irregularity. These finding definitely indicates substantially invasive cancer. (Therap Adv Gastroenterol. 2016)
