*2.4. Relationship between BMI-1 Epithelial and Stromal Expression and Clinicopathological Parameters in NEOC*

The statistical analysis showed significant correlations between BMI-1 expression in the tumor cells (low/high), the stroma (negative/positive), and the tumor histological subtypes (*p* = 0.002 and *p* = 0.04, respectively) (Table 3). No associations were found for the other clinical clinicopathological parameters.

LGSC (low-grade serous carcinoma); LGEC (low-grade endometrioid carcinoma); COC (clear cell ovarian carcinoma); MOC (mucinous ovarian carcinoma); HGSC (high-grade serous carcinoma); HGEC (high-grade endometrioid carcinoma); NED (no evident data about residual tumor).
