However, a low CR rate does not mean that it is unreasonable to schedule ER of UD-EGC. If ER is in fact curative, the long-term outcomes including survival rate are excellent. Quality of life is good because maximal stomach preservation is possible. However, UD-EGC and D-EGC differ histologically. Thus, when ER is contemplated to treat UD-EGC, a careful approach employing strict criteria is essential because the biology of UD-EGC and D-EGC differ.展开更多
