A positive correlation was found between the levels of ANXA2 and the risk of recurrence and the tumor histology, showing those patients with non-endometrioid tumors and high risk of recurrence had higher ANXA2 levels in purified EVs (* p = 0.019 and * p = 0.012, respectively according to Mann–Whitney U test) (Table 2, Figure 4B). Here, ANXA2 is linked to endometrioid tumor.
