ObjectiveTo evaluate the clinical outcomes of high-intensity focused ultrasound (HIFU) and surgery in treating uterine fibroids, and prepare for a definitive randomised trial. DesignProspective multicentre patient choice cohort study (IDEAL Exploratory study) of HIFU, myomectomy or hysterectomy for treating symptomatic uterine fibroids. Setting20 Chinese hospitals. Population or sample2411 Chinese women with symptomatic fibroids. MethodsProspective non-randomised cohort study with learning curve analysis (IDEAL Stage 2b Prospective Exploration Study). Main outcome measuresComplications, hospital stay, return to normal activities, and quality of life (measured with UFS-Qol and SF-36 at baseline, 6 and 12 months), and need for further treatment. Quality-of-life outcomes were adjusted using regression modelling. HIFU treatment quality was evaluated using LC-CUSUM to identify operator learning curves. A health economic analysis of costs was performed. Results1353 women received HIFU, 472 hysterectomy and 586 myomectomy. HIFU patients were significantly younger (P < 0.001), slimmer (P < 0.001), better educated (P < 0.001), and wealthier (P = 0.002) than surgery patients. Both UFS and QoL improved more rapidly after HIFU than after surgery (P = 0.002 and P = 0.001, respectively at 6 months), but absolute differences were small. Major adverse events occurred in 3 (0.2%) of HIFU and in 133 (12.6%) of surgical cases (P < 0.001). Median time for hospital stay was 4 days (interquartile range, 0-5 days), 10 days (interquartile range, 8-12.5 days) and 8 days (interquartile range, 7-10 days). ConclusionsHIFU caused substantially less morbidity than surgery, with similar longer-term QoL. Despite group baseline differences and lack of blinding, these findings support the need for a randomised controlled trial (RCT) of HIFU treatment for fibroids. The IDEAL Exploratory design facilitated RCT protocol development. Tweetable abstractHIFU had much better short-term outcomes than surgery for fibroids in 2411-patient Chinese IDEAL format study. Tweetable abstract HIFU had much better short-term outcomes than surgery for fibroids in 2500-patient Chinese IDEAL format study.
