Selective Progesterone Receptor Modulators for the Treatment of Uterine Leiomyomas

摘要

Uterine leiomyomas have drawn much attention since being described more than 200 years ago. These common benign uterine tumors often present with prolonged menstrual bleeding, pelvic pressure, and reproductive disorders and pose a true financial burden on health care systems all over the world. Over the past few decades, surgical treatment of uterine leiomyomas has received most of the focus compared with other treatment options. Choosing the appropriate surgical technique depends on many factors such as uterine leiomyoma location, patient's age, interest in future fertility, concomitant comorbidities, and the patient's preference. Pharmacologic treatments such as gonadotropin-releasing hormone agonists and antagonists have been used for the treatment of symptomatic uterine leiomyomas with only partial success. Myriad side effects and limited clinical results have rendered them less popular and have exposed a true need for new effective medical treatments. Recently, treatment with selective progesterone receptor modulators has shown promising results with shrinkage of uterine leiomyomas and a prolonged clinical effect. Selective progesterone receptor modulators provide hope for women with this challenging condition and are a promising new option in the armamentarium of medical treatments for uterine leiomyomas.
