Plain English Summary

Background and study aims
Fibroids are the most common benign tumor in women and by the time they are 50 years old around four out of five women will have had a fibroid. Of the women who develop fibroids, around half will experience symptoms that will adversely affect their quality of life. These symptoms can be quite severe and may include severe abdominal pain, pain during intercourse, heavy and painful menstrual bleeding, and a constant feeling of needing to go to the toilet. On top of this, some women with fibroids may experience difficulty in conceiving, and if they do conceive they are at a higher risk of miscarriage compared with women of the same age without fibroids. As many women are starting a family later in their life, fibroids are a growing problem.
Treatments for fibroids are available and fall into two main types: drug and surgical. Women with symptomatic fibroids often respond poorly to drug treatments and many find the side effects of these hormonal preparations unacceptable. This means that drug treatments may only be given for a short time, usually to dampen down the most severe symptoms and to try and shrink the fibroid before it is surgically removed. In the NHS today there are currently three surgical treatments readily available for fibroids: hysterectomy, myomectomy, and uterine artery embolisation (UAE). There are many different types of hysterectomy but they all have in common the removal of the womb. Studies have shown that many women regard their womb as being integral to their femininity and sexuality, and so it is unsurprising that if asked what sort of treatment they would like to receive for their fibroids, the vast majority of women would like to receive a treatment that allows them to retain their uterus. With many hysterectomies being performed to treat benign conditions, this has led many women to question if they are losing their wombs unnecessarily. With numerous women now looking for an alternative to hysterectomy, myomectomy and UAE are growing in favour. During a myomectomy the fibroids are surgically removed but as much of the uterus as possible is preserved. Similarly, UAE, where a very thin hollow tube is used to deliver small beads which block the blood flowing to the fibroid, is also a womb-preserving procedure.
With both myomectomy and UAE having their own risks and potential side effects, many health care professionals are uncertain which is the best one to offer to women who wish to retain their wombs. A few studies have compared UAE with myomectomy but these did not contain enough patients to give a definite result. This means that there is uncertainty as to what is the best treatment to offer to women with fibroids who want to retain their womb. This study aims to compare the changes in the quality of life women experience after their fibroids are treated with either UAE or myomectomy.

Who can participate?
Women aged over 18 years with symptomatic fibroids who do not wish to have a hysterectomy and are suitable for either treatment (myomectomy or embolisation).

What does the study involve?
Participants will be randomly allocated to have either a myomectomy or UAE. We will record how well the participants feel after two years and four years using questionnaires. We will also measure the changes in menstrual blood flow after each procedure as well examining if UAE and myomectomy change the level of ovarian hormones associated with fertility. Of course, there is a more direct method of measuring fertility, and we will record the outcome of any pregnancy that may occur in the women involved in the study. To measure the effectiveness of myomectomy and UAE, information on any follow-up procedures that women may have to undergo will also be collected.

What are the possible benefits and risks of participating?
You will not gain any individual benefit by taking part in the study but the study will provide valuable information to decide which treatment is best for future women suffering from fibroids. Myomectomy and UAE are both safe procedures and are in routine use within the NHS. Some studies have suggested that women who have a UAE recover from their operation more quickly than those who have a myomectomy, but may be more likely to have the need for more treatment in the future. On top of this, both myomectomy and UAE are associated with a range of complications. Although rare, there are risks for each procedure. For myomectomy the possible risks include: haemorrhage, injury to the uterus, damage to the nearby organs of the urinary system, formation of scar tissue (adhesions) within the uterus, infection, blood clots and eventual re-growth of fibroids. For UAE the possible risks include: damage to the uterus, bladder, vulva and ovaries, flu-like symptoms, pain, vaginal discharge and early menopause. The effect that myomectomy and UAE have on the chance of getting pregnant is unknown at present. In order to ensure that the tube delivering the beads is in the right place it will be guided there under x-ray imaging. Whilst any exposure to ionising radiation carries an increased risk of developing cancer, it is the size of this risk that is important. The lifetime risk of developing a fatal cancer following UAE is 1 in 3,330. This is similar to the lifetime risk of dying from an accident at work in the manufacturing industry, and a lot less than the lifetime risk of dying in a transportation accident in the UK (1 in 240). Your doctor will discuss the risks and discomforts of the allocated treatment and give you more details of what to do if you experience any side effects.

Study information

Scientific title

A Randomised trial of treating Fibroids with either Embolisation or Myomectomy to Measure the Effect on quality of life among women wishing to avoid hysterectomy: The FEMME study

Acronym

FEMME

Study hypothesis

A fibroid is a common non-cancerous growth of the uterus (or womb). Many women have fibroids without knowing it and do not need treatment. Larger or multiple fibroids can cause abnormal vaginal bleeding, pain, abdominal discomfort or bloating, bladder problems and other symptoms. The surgical removal of the fibroid without removing the womb (myomectomy) is possible in some patients. Uterine artery embolisation (UAE) is a newer treatment, which works by blocking the blood supply to the fibroid and causing it to die and shrink over a period of several months.

UAE and myomectomy are safe, effective procedures, each with advantages and disadvantages. To control symptoms, the choice is currently very uncertain and doctors do not know which women will benefit most from either procedure.

Since the options are so different, requiring very different hospital stays, possibly with different effects on fertility, sexual function and recurrence of fibroids, it is important to compare the two procedures against each other.

The FEMME trial is a multicentre randomised trial comparing UAE with myomectomy for women with symptomatic fibroids wishing to retain their womb. 216 eligible women will be randomised in a 1:1 ratio to myomectomy or embolisation. Participants will be recruited from over 20 UK hospitals by gynaecologists and interventional radiologists. The primary outcome of quality of life will be assessed by use of a disease specific questionnaire at two years. Effectiveness will also be assessed at 6 months and 1 and 4 years after treatment. Secondary outcomes include effect on menstrual bleeding, pregnancy outcomes, further treatment and adverse events. Ovarian function will be assessed on a subgroup of women. Data on resource use will be collected to for an economic evaluation.
