Methods: A total of 129 EP patients and an equal number of disease-free women were evaluated for ER and PR expression in endometrial tissues. Correlation with EP incidence was analyzed, as well as diagnostic value via receiver operating characteristic curve. Results: ER expression was higher and PR was lower in patients than in controls (p < 0.01). ER levels positively correlated with EP incidence, and PR negatively (p < 0.01). Receiver operating characteristic curves gave ER an area under the curve of 0.6168 (95% CI: 0.5479-0.6856; p < 0.0001) and PR 0.739 (95% CI: 0.6776-0.8003; p < 0.0001). Conclusion: Imbalance in ER and PR expression associates with EPs formation, offering clinical insights into EP pathology.
