 Tumor invasion of the gastrointestinal tract is apparent by the anatomical structure of the gastrointestinal wall. The TNM classification has been widely used in the world, but the original classification of tumor invasion depth approved by the Japanese Research Society for Gastric Cancer has been used in Japan. Differences observed in both the classifications of early cancer caused various problems, and to resolve these problems the Japanese classification was recently modified to be consistent with the TNM classification.

 The early cancer is sub-classified according to the value of the invasion depth. An objective standard of the invasion depth came to be used, but the measurement includes various histopathological problems. Therefore, further clarification of the measurement procedure is required. In addition, further examination is necessary to determine whether vessel permeation should be included in the measurement of invasion depth.
