Abstract

Objective(s): To evaluate the effects of two doses of medroxyprogesterone acetate (MPA) on uterine leiomyoma sizes and on uterine bleeding pattern in postmenopausal women treated with oral hormone replacement therapy (HRT). Study design: Thirty natural postmenopausal women affected by uterine leiomyomas were enrolled and treated with oral micronized estradiol (E2) at dose of 2mg per day, and randomized to receive in association MPA at dose of 2.5mg daily (group A) or of 5mg daily (group B). At the beginning of the study and after 1 year of treatment, uterine leiomyomata dimensions were measured using transvaginal ultrasonography (TV-USG). The subjects were instructed to note on a daily dairy the number and severity of abnormal uterine bleeding (AUB) episodes. Results: After 1 year of therapy, a significant changes in mean uterine leiomyomas size was observed in the group treated with higher dose of MPA. No significant differences in uterine bleeding were detected between the two groups. Conclusion(s): In postmenopausal women with uterine leiomyomas, it is necessary to use the minimal efficacious dose of progestin during HRT because of a higher risk to increase the tumors dimensions.
