Midterm outcome of radiofrequency thermal ablation for symptomatic uterine myomas.

BACKGROUND: Over the past decade an increasing demand for uterine-sparing treatment to manage symptomatic uterine myomas has become apparent in women's health care. A preliminary report showed that radiofrequency ablation (RFA) of uterine fibroids under laparoscopic guidance was a safe and effective minimally invasive approach with encouraging short-term results. The purpose of this study was to evaluate the midterm outcomes of radiofrequency ablation (RFA) of uterine myomas in terms of durability of symptom control and level of health-related quality of life. METHODS: Consecutive women with symptomatic uterine myomas, no plans for future pregnancy, and who declined hysterectomy were offered RFA ablation of uterine fibroids under laparoscopic guidance. Only 25 patients who completed at least the one-year follow-up assessment were included in the study group. Follow-up evaluations were scheduled at 1, 3, 6, 9, and 12 months and thereafter annually following the procedure. Improvement in myoma-related symptoms and impact on quality of life were assessed using a validated questionnaire (UFS-QOL). RESULTS: The median number of myomas treated per patient was 1 (range = 1-3). The median baseline volume of the dominant myoma was 76.8 cm3 (range = 14.8-332.8). No intraoperative or postoperative complications occurred. The median follow-up time was 24 months, with nine women completing three years of follow-up. The median reduction in myoma volume was 68.8% and 77.9% at six months and one year, respectively. No further change in fibroid size was observed at two years and three years. One year after the procedure, one woman (4%) underwent hysterectomy for recurrence of fibroid-related symptoms. Quality-of-life measures showed significant and durable improvement compared with baseline. CONCLUSIONS: RFA of symptomatic fibroids seems a valuable alternative to major surgery, with durable symptom relief for most patients and a low chance of recurrence at midterm
