Abstract
|
|
|
Background: The pathogenesis and etiology of endometrial polyps has not been elucidated. In this study, we aimed to examine the pathogenic mechanisms of endometrial polyp development using immunohistochemistry. We evaluated the expression of galectin-3 and cyclooxgenase-2 (COX-2) during the menstrual cycle in premenopausal women with endometrial polyps or normal endometrium.
Methods: Thirty-one patients with endometrial polyps and 50 healthy control patients were included in this study. The levels of expression of COX-2 and galectin-3 were studied by immunohistochemistry.
Results: The percentage of COX-2?positive cells and the intensity of COX-2 staining in the endometrium did not vary during the menstrual cycle either in the control group or in patients with endometrial polyps. However, expression of galectin-3 was significantly lower in endometrial polyps and during the proliferative phase of the endometrium compared with the secretory phase.
Conclusions: Our data suggests that the pathogenesis of endometrial polyps does not involve expression of COX-2 or galectin-3.
