Significantly, we found a strong concordance between the XPO1 overexpression and high Ki67 expression in the tumor cells within the most tissue sections that showed immunoreactivity for both XPO1 and Ki67, and the XPO1 overexpression was strongly associated with the high Ki67 expression (P=0.001) (Table 2 and Figure 2). Here, MKI67 is linked to neoplasm.
