High-intensity Focused Ultrasound in Treatment of Uterine Fibroid
Study Details
Study Description
Brief Summary
Uterine fibroids are common uterine benign neoplasm. They can cause abnormal menstrual bleeding, pelvic discomfort and urinary frequency. Although surgical intervention is the definitive treatment, some women prefer to have their uterus preserved. High-intensity focused ultrasound (HIFU) therapy is receiving increasing interest in the management of uterine fibroids by inducing focal thermocoagulation of the fibroids. Results obtained by various research groups have shown that HIFU treatment is safe, effective and is highly acceptable to patients. The main objective of this study is to evaluate the therapeutic efficacy of HIFU in the treatment of uterine fibroids.
In this proposed study, 20 patients who have symptomatic uterine fibroids who meet the study inclusion criteria will be invited to participate in the study which involves the use of HIFU in the management of the fibroid. Background information of the patients such as age, body mass index, hormonal (pre- or postmenopausal) status and the presence of chronic medical disease will be collected. Subjects will also be asked to complete an eight-item section of a Uterine Fibroid Symptom and Quality Of Life Questionnaire (UFS-QOL) which evaluate the effect of the fibroid on the quality of life of women.

Outcome Measures
Primary Outcome Measures
- Efficacy of HIFU in reducing the size of the uterine fibroids by sonographic measurements [The changes from baseline to post12-month treatment will be captured]
By sonographic measurements at baseline, post 1-month, post 3-month, and post 12-month, the size of the uterine fibroids will be evaluated by physicians
Secondary Outcome Measures
- Patient satisfaction score after HIFU treatment of uterine fibroid [Up to 12 months]
Patients will be asked to give the satisfaction score (0= not satisfactory, 5= very satisfactory) at each follow up (i.e. post treatment 1 months, 3 months, 6 months and 12 months)
- Change of perceived symptoms after HIFU treatment by using the Uterine Fibroid Symptoms Quality Of Life Questionnaire (UFS_QOL) [Up to 12 months]
By using the Uterine Fibroid Symptoms Quality Of Life Questionnaire (UFS_QOL) at each follow up (i.e. from baseline to post 1- month, post 1-month to post 3-month, post 3-month to post 6-month, post 6-month to post 12-month treatment will be captured).
- Risks and adverse effects of HIFU in the treatment of uterine fibroid [Up to 12 months]
Patient will be evaluated for abnormal laboratory values and/or adverse events that are related to treatment at each follow up (i.e. post treatment 1 months, 3 months, 6 months and 12 months)
- Subsequent management after HIFU treatment of uterine fibroid [Up to 12 months]
By physician's judgment at each follow up (i.e. at post treatment 1 months, 3 months, 6 months and 12 months), the need for subsequent additional treatments (such as hysterectomy, uterine artery embolization, or any type of hormonal treatment) will be evaluated.
- Efficacy of HIFU in reducing the size of the uterine fibroids by MRI measurements [The changes from baseline to post 6-month treatment will be captured]
By MRI measurements at baseline, post 6-month, the size of the uterine fibroids will be evaluated by physicians
