 We examined the findings about 9 early gastric cancers penetrating to the submucosal layer. It was difficult to study the difference of cancer penetration findings ; slight(within 500μm)and more because we had few cases suitable for this aim. It was necessary to evaluate the thickness of the cancer in order to distinguish submucosal penetration within 1,000μm from that exceding this depth. So, it is necessary to pay attention to the changing wave of the cancer surface according to expansion and contraction as well as conventional findings. We must accumulate findings about submucosal gastric cancers because quantitative data about submucosal invasion of early gastric cancers can provide knowledge needed for their treatment.
