AbstractBackground: Cancer survivors are often reluctant to discuss sexual complaints with their oncologists and treatment is frequently unsatisfactory due to paucity of controlled studies and inapplicability of vaginal estrogen. We aimed to evaluate efficacy and tolerability of platelet-rich plasma (PRP) injections alone or in combination with noncrosslinked hyaluronic acid compared with standard therapy with topical hyaluronic acid gel in the management of cancer therapy-induced or aggravated vulvovaginal atrophy. Materials and Methods: This prospective, parallel-group comparative study was conducted on 45 female patients with a history of cancer and complaining of symptoms of vulvovaginal atrophy either induced or aggravated by cancer treatment. Patients were randomly divided into three groups (A, B, and C). Group A patients received two submucosal vaginal PRP injections, group B patients received two similar injections of PRP combined with noncrosslinked hyaluronic acid, and group C received a topical vaginal hyaluronic acid gel applied three times weekly for 2 months. Main outcome measures were vulvovaginal atrophy symptom severity and vaginal health index (VHI) scores before treatment (v0), 1 month from baseline (v1), 2 months from baseline (v2), and 3 months after the last visit (v3). Results: Both groups A and B showed greater improvement of frequency of intercourse avoidance than group C. Group A showed greater improvement of dyspareunia than group C. Groups A and B demonstrated greater improvement of vaginal pH, fluid volume, and total VHI scores than group C. Short-term topical hyaluronic acid (HA) was not associated with any significant improvement of vaginal elasticity. Group B showed greater improvement of vaginal dryness and moisture scores than group C. Reported adverse events were injection-related pain in all patients of groups A and B and vaginal spotting in groups A and B. Conclusion: Both PRP and PRP-HA have comparable efficacy and patient-reported treatment satisfaction. PRP injections were better tolerated by patients than PRP-HA. Clinical trial registration number: NCT05782920.
