The study demonstrates that non-hormonal hyaluronic acid (HLA) vaginal gel is feasible and effective in improving vulvovaginal estrogen-deprivation symptoms in postmenopausal women with a history of hormone receptor-positive (HR+) cancer. The use of HLA significantly improved participants' vulvovaginal health, sexual function, and menopausal symptoms.
Purpose To assess the feasibility and efficacy of a non-hormonal hyaluronic acid (HLA) vaginal gel in improving vulvovaginal estrogen-deprivation symptoms in postmenopausal women with a history of hormone receptor-positive (HR+) cancer. Methods For this single-arm, prospective longitudinal trial, we identified disease-free patients with a history of HR+ breast cancer treated with aromatase inhibitors or HR+ endometrial cancer treated with surgery and postoperative radiation. Participants used HLA daily for the first 2 weeks, and then 3x/week until weeks 12-14; dosage was then increased to 5x/week for non-responders. Vulvovaginal symptoms and pH were assessed at 4 time points (baseline [T1], 4-6 weeks [T2], 12-14 weeks [T3], 22-24 weeks [T4]) with clinical evaluation, the Vaginal Assessment Scale (VAS), Vulvar Assessment Scale (VuAS), Female Sexual Function Index (FSFI), and Menopausal Symptom Checklist (MSCL). Results Of 101 patients, mean age was 55 years (range, 31-78), 68% (n = 69) were partnered, and 60% (n = 61) were sexually active. In linear mixed models, VAS/VuAS scores significantly improved at all assessment points (all p < 0.001). MSCL scores similarly improved (all p < 0.001). FSFI scores significantly improved from T1 to T2 (p < 0.03), T3 (p < 0.001), and T4 (p < 0.001). Severe vaginal pH (> 6.5) decreased from 26% at T1 to 19% at T4 (p = 0.18). Conclusions HLA moisturization improved vulvovaginal health/sexual function of cancer survivors. While HLA administration 1-2x/week is recommended for women in natural menopause, a 3-5x/week schedule appears to be more effective for symptom relief in cancer survivors.
