The growth pattern of 137 cancers of surgically removed stomach specimen were studied in relation to histological type and stromal reaction, namely, the degree of lymphocytic infiltration and fibrosis, and several characteristies were noted. Generally, stromal fibrosis increased more in the expanding type of growth of the cancer while the degree of lymphocytic infiltration did not. As an invasive growth pattern of cancer 5 directly affect on the prognosis of the stomach cancer, a graph was designed which can be used to help to predict the degree to which the cancer may be experted to have a greater tendency to expand locally or invade deeper. However, an increase in the number of metastatic lymph node parallels an increase in the size of the cancer.
