As can be seen in Figure 10, for patients labeled A, who are at minimal risk for progression towards colon cancer, the median percents of absorptive cells with high expressions of Pms2, Ercc1, Xpf and Ku86 in their tissue sections were each above 90%, and at least 75% of all tissue sections of these lowest risk patients had more than 90% of the absorptive cells with high expression of all 4 proteins (values within the box plus within whiskers with higher values). This evidence concerns the gene ERCC4 and colonic neoplasm.
