Finally, in Figure 5 are presented the results of Kaplan–Meier analyses in 98 patients with colon cancer stage III, with separate panels for those with a high Ki-67 expression (⩾40%, n=41) and those with a low Ki-67 expression (<40%, n=57), showing the effect of randomisation group on RFS. This evidence concerns the gene MKI67 and malignant colon neoplasm.
