Plain English Summary

Background and study aims
Fibroadenoma is a common benign lump of the breast present in 1 in 10 women attending breast clinics. The current management of these lumps is patient reassurance once diagnosed and surgical removal only if the lump is growing or is painful. This is because of the risk of undesirable scarring. The aim of this study is to use a high intensity focused ultrasound (HIFU) machine (Echopulse TM) to heat up the breast lump and cause it to shrink. This will eliminate the need for any invasive procedure like surgery and potential undesirable side effects.

Who can participate?
HIFU group: Women over 18 years of age with ultrasound confirmed and symptomatic cases of fibroadenomas. Patients over the age of 25 need a biopsy to confirm the diagnosis of a FAD.
Control group: Patients who are eligible to participate in the study and invited to come back six months after their FAD diagnosis for an additional ultrasound scan in order to determine the natural change in volume of FAD. These patients do not undergo HIFU treatment.

What does the study involve?
HIFU group: All patients are given local anaesthetic and treated with the ultrasound device as a day case in the outpatient unit. The ultrasound machine is used to image the lump and determine where to treat. Once in the suite patients are placed on their side and local anaesthetic is administered. A gel pad attached to the device is then lowered onto the site of treatment. The HIFU system is used to image the fibroadenomata and set to deliver HIFU treatment. The total treatment time is about 90 minutes. Once the treatment is completed the patient is observed in the discharge suite for 1 hour before being discharged when they meet the local discharge criteria. All patients are reviewed after the procedure and at 2 weeks, 3, 6 and 12 months with a repeat ultrasound scan at each appointment.
Control group: all patients are asked to return to the breast clinic six months after initial diagnosis of their FAD for an additional ultrasound scan.

What are the possible benefits and risks of participating?
HIFU group: The benefit for the patients is that they will not have invasive surgery to treat their fibroadenoma and this will prevent any potential scarring or cosmetic complications. Participants will experience some discomfort after the procedure requiring oral pain relief. The HIFU treatment can result in skin changes and we would expect patients to experience a degree of mild swelling and redness with or without bruising at the treatment site (lasting up to 14 days). Rarely patients may experience minimal changes in skin colour (lasting several months) and superficial skin burns (resolving without any further medical treatment).
Control group: No additional benefits or risks.

Scientific titleHigh Intensity Focused Ultrasound for the treatment of Fibroadenoma (HIFU-F) Study: a non-randomised study
Study acronymHIFU-F
Study hypothesisThis non-invasive procedure using high intensity focused ultrasound can potentially replace the need for surgical interventional and minimise the risk of scarring and undesirable cosmetic outcomes. In addition to minimising in-patient care requirements.

ConditionFibroadenoma
InterventionCurrent interventions as of 02/06/2016:
HIFU group
Patients with confirmed fibroadenomas will be administered a local anaesthetic and a coupling media in the form of a gel pad attached to the device will then be lowered onto the site of treatment. The Echopulse TM will be used to image the lesion in 2 perpendicular dimensions and set to deliver HIFU to the circumferential surface area of the lesion. Once the treatment is completed the patient will be observed in the discharge suite for a period of 1 hour prior to discharge subject to satisfactorily complying with local day case discharge protocols. All patients will be reviewed after the procedure and at 2 weeks, 3, 6 and 12 months with a repeat ultrasound scan at each appointment.

Control group
Patients will undergo an ultrasound scan six months after FAD diagnosis in order to determine the change in volume over time.
