Their findings indicate that AE shows a level of proliferation activity that falls between typical endometriosis and ovarian carcinoma, positioning it as a precancerous condition (with Ki-67 indices of 2.7 ± 0.90, 9.9 ± 1.73, and 23.1 ± 3.29, respectively). Here, MKI67 is linked to ovarian carcinoma.
