MKI67 and gastric cancer: The epithelial staining of Ki67 was significantly different in all groups (Kruskal-Wallis H = 57.31 p = 0.0001) with a progressive increase from controls to AG and IM in patients without gastric cancer (Mann-Whitney’s U test p = 0.0001) and to intestinal type gastric cancer (Mann-Whitney’s U test p = 0.001).
