These observations are consistent with our findings only in the group where EC was found with coexisting benign polyps (33.5%), whereas in other EC groups, Ki-67 antigenic activity was significantly lower, for example, 2.8% in EC focus in a polyp (p = 0.019) and 1.3% in EC cases with a previously resected polyp (p < 0.000). Here, MKI67 is linked to polyp.
