OBJECTIVE: To evaluate the 12-month safety and effectiveness of transcervical ablation for the treatment of symptomatic uterine leiomyomas.

METHODS: In this prospective, multicenter, single-arm interventional trial, transcervical ablation was performed on 1–10 leiomyomas per patient with leiomyoma diameters ranging from 1 to 5 cm. Treated leiomyomas included all nonpedunculated types. Coprimary endpoints assessed at 12 months were reduction in menstrual blood loss and absence of surgical reintervention. Additional assessments included symptom severity, quality of life, patient satisfaction, reductions in uterine and leiomyoma volumes, and safety.

RESULTS: One hundred forty-seven patients were enrolled and treated in the United States and Mexico. The study met its coprimary endpoints at 12 months (N=143; full analysis set), because 64.8% of patients (95% CI 56.3–72.6%) experienced 50% or greater reduction in menstrual bleeding and 99.3% of patients (95% CI 95.1–99.9%) were free from surgical reintervention. The mean pictorial blood loss assessment chart score decreased by 38.9%, 48.4%, and 51.1% at 3, 6, and 12 months, respectively (P<.001), and 95.1% of patients experienced a reduction in menstrual bleeding at 12 months. There were significant mean improvements in symptom severity and health-related quality of life of 32.1 points and 43.7 points, respectively, at 12 months (all P<.001). Mean maximal leiomyoma volume reduction per patient was 62.4% (P<.001). More than half of patients returned to normal activity within 1 day, 96.3% of patients reported symptom improvement at 12 months, and 97% expressed satisfaction with the treatment at 12 months. There were no device-related adverse events.

CONCLUSION: Transcervical ablation was associated with a significant reduction in leiomyoma symptoms with no device-related adverse events and a low surgical reintervention rate through 12 months, demonstrating its potential to safely and effectively treat all nonpedunculated leiomyoma types through a uterus-conserving, incisionless approach.
