Given that we found a very strong correlation between CA20 and CIN25 in breast tumors and it has been shown by others that CA and CIN are correlated in breast tumors15, it is tempting to speculate that CA20 captures CIN, thus rendering CIN25 redundant, and perhaps also captures other aggressive phenotypes not encompassed by CIN25 that are consequences of CA. This evidence concerns the gene PDXP and breast neoplasm.
