There is no robust evidence to define a safe proximal margin by distance for early gastric cancer (EGC). The discussion on resection margin should not only focus on the oncologic safety, but also the postgastrectomy quality of life. The distance 1-10 mm is only acceptable for those endoscopic treatment fit EGC patients. For endoscopic unfit EGC cases, if the borderline of tumor is able to be clearly determined intraoperatively, the distance 1-3 cm is recommended for proximal resection margin. If there is any uncertainty on the tumor borderline, the distance 3-5 cm should be considered for proximal margin.
