PROSPECTIVE STUDY OF THE EFFECTIVENESS OF DIFFERENTIATED THERAPY OF ENDOMETRIUM HYPERPLASIA WITHOUT ATYPIA IN WOMEN IN REPRODUCTIVE AGE

The paper considers the issues of improving the effectiveness of treatment of endometrial hyperplasia without atypia in women of reproductive age with the use of progestins as a pathogenetic therapy and should be personalized (targeted) taking into account the receptor sensitivity of endometrial tissue to progestins. The positive effects of progestin use are mainly due to the expression of progesterone receptors in the endometrial tissue, which must be taken into account during hormone therapy. A prospective study was performed in 60 patients of reproductive age with abnormal uterine bleeding, who according to the results of histological examination of endometrial tissue was diagnosed with endometrial hyperplasia without atypia. All patients were treated with micronized progesterone at a dose of 400 mg / day continuously for 6 months. To determine the effect of the use of progestins was performed by studying the expression of receptors for estrogen (ER) and progesterone (PR) in histological blocks of the endometrium by immunohistochemistry. In all women there was a significant expression of EP in endometrial cells, which led to its proliferative activity against the background of reduced expression of progesterone receptors by 65%, which caused no effect of therapy in 25% of women. Studies have shown that when deciding on the appointment of micronized progesterone for the treatment of endometrial hyperplasia without atypia, it is recommended to study the expression of progesterone receptors in endometrial tissue to clarify the possibility of a pharmacological effect. Treatment of endometrial hyperplasia without atypia with progesterone drugs is not effective in low expression of progesterone receptors in endometrial tissue. Based on this, we can identify a group of women with progesterone-resistant hyperplasia who require other treatments.
