Background. Currently, there is an increase in benign ovarian tumors, which, according to the results of numerous studies, negatively affect the reproductive health of women. Patients seeking to preserve their reproductive function prefer organ-preserving surgical interventions, however, in clinical practice, adnexectomy is often necessary due to the absence of intact ovarian tissue.
Aim. Analysis of the morphofunctional state of the endometrium and its receptivity in patients with serous and mucinous ovarian cystadenomas before and after surgical treatment.
Methods. The prospective study included patients of reproductive age with benign epithelial tumors: serous/mucinous cystadenomas who had not received hormonal drugs for six months prior to surgical treatment. 32 patients with serous cystadenoma were included in group I, 30 patients with mucinous cystadenoma in group II. Before and 6-12 months after unilateral salpingo-oophorectomy, a pipel biopsy of the endometrium was performed during the "implantation window". The qualitative and quantitative parameters of pinopodia were studied, the expression of estrogen (ER) and progesterone (PR) receptors in the glands and stroma of the endometrium were studied.
Results. In the postoperative period, an increase in the number of mature pinopodia, a growing in the expression of ER in the stroma and PR in the stroma and glands was revealed. When analyzing the data in patients with mucinous cystadenoma After surgical treatment, in patients with mucinous cystadenoma, in comparison with the data of the serous patients in the glandular component of the endometrium, the expression of both ER and PR was lower, and the expression of PR in the stromal component was also lower, a growing in the number of developing pinopodia was recorded.
Conclusion. The results of our study showed that benign ovarian tumors is accompanied by disorders of the morphofunctional state and receptivity of the endometrium.
