Selective estrogen receptor modulator and selective progesterone receptor modulator: therapeutic efficacy in the treatment of uterine leiomyoma.

Recent advances in endocrinology open a door for clinical application of selective estrogen receptor modulator (SERM) and selective progesterone receptor modulator (SPRM) in the treatment of uterine leiomyoma. With regard to SERM, treatment with raloxifene is shown to reduce leiomyoma size in postmenopausal women. Although raloxifene causes shrinkage of leiomyomas in combination with gonadotropin-releasing hormone agonist in premenopausal women, the effects of monotherapy with raloxifene on leiomyoma growth in premenopausal women remain controversial. By contrast, tamoxifen may not be suitable for long-term treatment of leiomyomas due to an agonistic action on the endometrium. Treatment with progesterone antagonist (RU486) or SPRM (J867) has been demonstrated to inhibit leiomyoma growth and improve clinical symptoms in premenopausal women. No serious adverse effects associated with SERM or SPRM have been reported. In light of therapeutic efficacy and few adverse effects, SERM and SPRM may hold promise as novel treatment modalities for leiomyoma. Further studies are warranted to determine the optimal strategy for the treatment of leiomyoma with SERM and SPRM.
