Figure 1
Figure 1 Comparison of each discrepancy in the histologic type between biopsy and resected specimens with the Japanese Classification of Gastric Carcinoma. Pure D group: A pure differentiated component with no undifferentiated component; D > U group: A differentiated-predominant mixed type a < 50% undifferentiated component; U > D group: An undifferentiated-predominant mixed type with a > 50% undifferentiated component; and pure U group: A pure undifferentiated component with no differentiated component.

Figure 2 Comparison of each discrepancy in the histologic type between biopsy and resected specimens in the tumor-node-metastasis classification. Pure D group: A pure differentiated component with no undifferentiated component; D > U group: A differentiated-predominant mixed type with a < 50% undifferentiated component; U > D group: An undifferentiated-predominant mixed type with a > 50% undifferentiated component; and pure U group: A pure undifferentiated component with no differentiated component.

Figure 3 Comparison of detected histologic mixed-type gastric cancer rates between biopsy and resected specimens in the Japanese classification of gastric carcinoma and tumor-node-metastasis classification. Pure D group: A pure differentiated component with no undifferentiated component; D > U group: A differentiated-predominant mixed type with a < 50% undifferentiated component; U > D group: An undifferentiated-predominant mixed type with a > 50% undifferentiated component; and pure U group: A pure undifferentiated component with no differentiated component.
