Abstract

PURPOSE

To determine the long-term outcome of uterine fibroid therapy (UFE) using tris-acryl gelatin microspheres (TAGM).

MATERIALS

This was a multicenter prospective study of patients undergoing UFE with TAGM, and during this phase of the study, the clinical outcomes 3 years after treatment were assessed. Measures of outcome included the Ruta Menorrhagia Questionnaire, patient self-assessments of symptoms and impact on activities, patient satisfaction and health-related quality of life as measured by the SF-12. Long-term re-intervention rates were also assessed. The data were analyzed at each interval compared to baseline using appropriate statistical tests.

RESULTS

Of the 102 patients enrolled, 96 patients had complete baseline data and of these, 69 (72%) had known outcomes at 3 years after treatment. Sixty-one patients (64%) completed long-term follow-up without major intervention. An additional 8 patients (8.3%) underwent fibroid surgery (7 hysterectomies and 1 myomectomy). Among those without intervention, at 3 years after treatment, the mean Ruta Questionnaire Score was 19.3, compared to 47.9 at baseline and 24.5 at 3 months (P <.01). At baseline, 57% of patients had extremely heavy bleeding, while only 2% had that complaint at 36 months. At 36 months, much or moderate improvement in pelvic pain occurred in 83% of patients, pelvic discomfort in 83%, and urinary problems in 69% and 84% were moderately or very satisfied with their outcome.

CONCLUSIONS

Over the long-term, UFE using TAGM is effective and safe, with high levels of durable symptom control, improved health-related quality of life and patient satisfaction.
