Action of aromatase inhibitor for treatment of uterine leiomyoma in perimenopausal patients.

OBJECTIVE: To assess the effect of the aromatase inhibitor on patients with leiomyoma in the reproductive stage regarding reduction of uterine volume and control of symptoms. DESIGN: Clinical study. SETTING: Academic clinical practice. PATIENT(S): Twenty patients, over 35 years of age, with symptomatic uterine leiomyoma. INTERVENTION(S): Anastrozol, 1 mg/day for 12 weeks. MAIN OUTCOME MEASURE(S): Measurement of uterine volume, assessment of symptoms related to uterine leiomyoma, serum assay of follicle stimulating hormone (FSH), and estradiol. RESULTS: Average reduction of uterine volume of 9.32%, attaining up to 32%, and reduction of symptoms of uterine leiomyoma (menstrual volume, duration of menstruation, and dysmenorrhea). No significant change in serum levels of FSH and estradiol during use of the medication were observed. CONCLUSION(S): Anastrozol proved to be effective in reducing the volume of the uterus-leiomyoma structure, leading to the control of symptoms connected with the disorder without changes in serum FSH and estradiol.

Comparative study of different dosages of goserelin in size reduction of myomatous uteri.

STUDY OBJECTIVE: To compare uterine size reduction obtained with three monthly subcutaneous injections of 3.6 mg of goserelin versus a single subcutaneous injection of 10.8 mg. DESIGN: Prospective, randomized clinical trial (Canadian Task Force classification I). SETTING: Department of Gynecology and Obstetrics at the Hospital das Clinicas da Faculdade de Medicina da Universidade de Sao Paulo. PATIENTS: Forty-five premenopausal women with uterine leiomyomas and uterine size greater than 600 cm(3) randomized to one of two groups. INTERVENTION: Group A: 23 women received three monthly subcutaneous 3.6-mg doses of goserelin. Group B: 22 women received a single subcutaneous injection of 10.8 mg of goserelin. Follicle-stimulating hormone (FSH), estradiol, and hemoglobin levels were measured monthly. After 3 months, uterine size was determined by transvaginal and/or abdominal ultrasound. MEASUREMENTS AND MAIN RESULTS: In group A, mean reduction of uterine size was 43% (426 cm(3)) at the end of treatment. In Group B, mean reduction of uterine size was 54% (494 cm(3)). Serum levels of FSH and estradiol were in postmenopausal range during treatment. Hemoglobin level improvement was equivalent in both groups. CONCLUSION: Use of single injection of 10.8 mg of goserelin promoted significantly greater reduction in uterine size than three monthly 3.6-mg injections in patients with voluminous uterine leiomyomas.
