RESUMO
BACKGROUND: We evaluated the effectiveness of Ormeloxifene (Centchroman) on regression of Fibroadenoma in a double-blind randomized controlled trial. METHODS: Patients with biopsy proven Fibroadenoma were enrolled between March 2023 and October 2023 and divided in two arms- Ormeloxifene group and Placebo group. Effectiveness of the treatment was evaluated using USG. No residual mass was defined as complete regression and more than 30% decrease in size was considered as partial regression. RESULTS: A total of 130 consecutive patients with Fibroadenoma were randomized to Ormeloxifene group (n = 65) and Placebo Group (n = 65). Complete regression was observed in 9% (6/65) patients in Ormeloxifene group and 10.8% (7/65) in Placebo Group at the end of 12 weeks (p = 0.49). Twenty one patients taking Ormeloxifene reported adverse events as compared to none in the other group. CONCLUSION: In our study Ormeloxifene was not found to be effective in treatment of fibroadenoma and had concerning side effects.
