A prospective interventional study to evaluate the effects of medical therapy (Mifepristone 25 mg) on the management of uterine fibroids

Background and Objectives: In India, the uterine fibroid is a common indication of hysterectomy. An effective option for medical treatment may decrease the morbidity associated with hysterectomy. We aimed to evaluate the effect of mifepristone (25 mg), progesterone antagonist, on uterine fibroids in perimenopausal women. Methods: Fifty-four perimenopausal women of age ≥18 years having symptomatic uterine fibroids were selected from Gynecology OPD and given 25 mg mifepristone once daily continuously for 2–4 cycles of 3 months each. Variables such as baseline fibroid size, position, and hemoglobin were measured and followed at 3, 6, 9, and 12 months. The data were entered in MS EXCEL spreadsheet and analysis was done using Statistical Package for Social Sciences (SPSS) version 21.0. A P value of <0.05 was considered statistically significant. Results: Majority were intramural fibroids (70.37%) followed by submucosal in 16.67%. Size of fibroids ranged from <3 to >7 cm; the majority of fibroids were in 5–7 cm size. No significant association of location with the size of fibroid was found. Out of 54 cases included in the study, change in size in uterine fibroids was observed in 98.14% cases. There was an increase in hemoglobin, from 8.6 g% at baseline to 9.7 g% at 12 months. Conclusion: Mifepristone resulted in a reduction in uterine fibroids size and an increase in hemoglobin at the end of 12 months. It may be an option for uterine leiomyoma treatment, as it is given orally, cost-effective and has minimal side effects.
