High-intensity Focused Ultrasound in Treatment of Uterine Adenomyosis

Not Applicable
Conditions
Adenomyosis
Interventions
Procedure: HIFU treatment
Registration Number
NCT02954757
Lead Sponsor
Queen Mary Hospital, Hong Kong
Brief Summary

Uterine adenomyosis is a common uterine benign condition. They can cause abnormal menstrual bleeding, and menstrual pain. 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 adenomyosis 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 adenomyosis.

In this proposed study, 10 patients who have symptomatic uterine adenomyosis 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 adenomyosis. 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) and menstrual pain score which evaluate the effect of the adenomyosis on the quality of life of women.

Primary Outcome Measures
NameTimeMethod
Perceived symptoms change after HIFU treatment By using the menstrual pain scoreThe changes from baseline to post 12-month treatment will be captured

By using the menstrual pain score for pain evaluation 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).

Secondary Outcome Measures
NameTimeMethod
Subsequent management after HIFU treatment of uterine adenomyosisUp 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.

Perceived symptoms change after HIFU treatment By using the Uterine Fibroid Symptoms Quality Of Life Questionnaire (UFS_QOL)The changes from baseline to post12-month treatment will be captured

By using the Uterine Fibroid Symptoms Quality Of Life Questionnaire (UFS_QOL) for symptoms evaluation 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)

Patient satisfaction score after HIFU treatment of uterine adenomyosisUp 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- month, 3-month, 6-month and 12- month)

Risks and adverse effects of HIFU in the treatment of adenomyosisUp 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- month, 3-month, 6-month and 12- month)

Efficacy of HIFU in reducing the size of the adenomyotic lesion and the uterus by sonographic measurements.The changes from baseline to post 12- month treatment will be captured

By sonographic measurements at baseline, post 1-month, post 3-month and post 12-month treatment, the size of the adenomyotic lesion and the uterus will be evaluated by physicians.

Discomfort during procedure by using 10-cm visual analogue scaleimmediate after the treatment

By using 10-cm visual analogue scales (0 = no pain, 10 = worst pain). Women will be asked to give the pain score immediately after the HIFU treatment.
