OBJECTIVES: Focused ultrasound waves penetrate superficial tissues and are aimed toward the target tissues at specific depths to exert their biological effects. Focused ultrasound has been applied for a number of clinical indications, including vulval dystrophies and low-grade vulval disease. This study aimed to assess the efficacy and safety of focused ultrasound treatment of high-grade vulval intraepithelial neoplasia (VIN).
METHODS: Eighteen women with high-grade VIN were recruited and treated with focused ultrasound. During each posttreatment follow-up, the safety of, side effects of, and clinical responses to focused ultrasound were evaluated by a standardized protocol, including symptoms, clinical appearance, and histologic findings.
RESULTS: All patients completed the designed follow-ups. In most cases, superficial mild to moderate swelling and blisters were seen in the focused ultrasound-treated skin but not in adjacent normal skin. Of the 18 patients, 16 showed complete histologic regression and resolution of symptoms 6 months after treatment. Of the other 2 patients, 1 showed complete regression after a second focused ultrasound treatment. The other patient did not respond to the focused ultrasound treatment and underwent a partial vulvectomy 6 months after treatment. None of the patients developed invasive carcinoma of the vulva during the follow-up period. One patient had local pruritus that was not alleviated by anti-inflammatory medication and local care.
CONCLUSIONS: The complete responses observed in women with high-grade VIN treated by focused ultrasound, together with the preservation of adjacent normal tissue, suggest that focused ultrasound may be considered for treatment of high-grade VIN.
