The statistical significance of the relationship between tumour epithelial vimentin expression and a shorter postsurgical survival was more important when considering the cutoff of 10% (P<0.01, median postsurgical survivals 12.49 vs 19.72 months) (Figure 2) than for the cutoff of 1% (P=0.02, median postsurgical survivals 15.05 vs 19.52 months). This evidence concerns the gene VIM and neoplasm.
