Histopathological Study on the Relationship Between Macroscopical Findings and Prognosis of the Resected Gastric Cancer.-Evidence by histological study-

Abstract

It is well known that the depth of carcinomatous infiltration into the gastric wall influences on the prognosis after removal of the stomach cancer. It has been clarifid by many investigations that macroscopical findings of stomach cancer should be important for conjecture of the depth of carcinomatous infiltrations into the gastric wall. The extension of the lymph node metastasis should be closely related to the prognosis and it should be also very important to decid the extent of surgical removal of lymph nodes. Five handred thirty six stomach cancers, which were diagnosed and resected in our clinic from April 1967 to March 1974, were studied clinicopathologically to make clear the relationship between the macroscopical findings and the extension of the lymph node metastasis and the prognosis. These materials were macroscopically clossified into early type and advanced type. It was evidently demonstrated that the macroscopical findings and the size of gastric cancer had a close correlation with the extension of lymph node metastasis and prognosis and should be very important to decide the extent of surgical removal of lymph nodes.
