Background: Gynecologic symptoms and sexual dysfunction from endocrine therapy are troublesome side effects for a significant number of patients. This study explored amelioration of vaginal dryness and dyspareunia with fluocinonide cream, a strong topical corticosteroid. Methods: A single-arm, open-label phase II trial of topical fluocinonide 0.05% cream to improve vaginal symptoms in women on endocrine therapy in the adjuvant setting for early stage breast cancer was performed. Patients with vaginal symptoms applied topical vaginal fluocinonide 0.05% cream twice a day for two weeks then once daily for two weeks. Patients were assessed for symptoms by weekly completion of the Mayo/North Central Cancer Treatment Group Patient Pretreatment Questionnaire. The primary outcome was a change from baseline in patient-reported effects of vaginal dryness and dyspareunia on a scale from 0 (no symptoms) to 4 (very severe symptoms) from time of enrollment and at 4 weeks. Secondary outcomes were decrease in vaginal itching and total vaginal index score. Comparisons were made with Wilcoxon sign rank test with 2.5% significance level. Results: Thirty-four women were accrued. At 4 weeks compared with baseline, vaginal dryness improved from a median score of 2 (moderate symptoms) to 0 (no symptoms) (P < .001) and dyspareunia from 3 (severe symptoms) compared with 1 (mild symptoms) (P = .002). Percentage of patients who had > 2 point improvement in vaginal dryness and dyspareunia was 69.0% and 75% respectively. Secondary analysis showed decrease in vaginal itching score from 1 to 0 (P = .001) and vaginal index score of 6 to 1 (P = .002). Twenty-one patients experienced low-grade toxicities which were mostly limited to skin irritation. Conclusions: Fluocinonide 0.05% cream improves vaginal dryness and dyspareunia experienced by women receiving endocrine therapy and has the potential to improve quality of life of cancer survivors and compliance of endocrine therapy.
