Long-term outcome of MR-guided focused ultrasound treatment and laparoscopic myomectomy for symptomatic uterine fibroid tumors

BACKGROUND: Fibroid tumors are the most common benign tumors in women of reproductive age. Treatment is usually indicated for those who are symptomatic, with different techniques being used. OBJECTIVE: The purpose of this study was to compare the long-term outcome of laparoscopic myomectomy with magnetic resonance-guided focused ultrasound for symptomatic uterine fibroid tumors. STUDY DESIGN: A cohort study was conducted on all patients with symptomatic uterine fibroid tumors who were admitted to a single tertiary care center and treated operatively with laparoscopic myomectomy or treated conservatively with magnetic resonance-guided focused ultrasound from January 2012 until January 2017. Assessment for further interventions and sustained fibroid-associated symptoms was performed, with the use of the Uterine Fibroid Symptom and Quality of Life symptom severity score. RESULTS: One hundred fifty-four women met the inclusion criteria. Complete follow-up evaluation was achieved for 64 women who underwent laparoscopic myomectomy and for 68 women who were treated by magnetic resonance-guided focused ultrasound. Follow-up time was similar for the 2 groups (median, 31 months [interquartile range, 17-51 months] vs 36 months [interquartile range, 24-41]; P =.95). The rate of additional interventions was 5 (7.8%) and 9 (13.2%), respectively (P = 0.312). Similarly, the Uterine Fibroid Symptom and Quality of Life symptom severity score questionnaire score at follow-up interviews revealed comparable median scores of 17 (interquartile range, 12-21) vs 17 (interquartile range, 13-22) for laparoscopic myomectomy and magnetic resonance-guided focused ultrasound, respectively (P =.439). Analysis of each of the symptoms separately (bleeding, changes in menstruation, abdominal pain, bladder activity, nocturia, fatigue) did not change these findings, nor did a multivariate analysis. CONCLUSION: Satisfaction with long-term outcome and rate of reinterventions after magnetic resonance-guided focused ultrasound treatment or laparoscopic myomectomy for uterine fibroid tumors was comparable. Further larger randomized trials are needed to confirm these findings.
