October 11, 2021 updated by: Theraclion

Treatment of Breast Fibroadenoma With FastScan High Intensity Focused Ultrasound (HIFU)

This study evaluates the efficacy of the HIFU for the treatment of breast fibroadenoma with the FastScan version using assessment of patient experience and adverse event reporting.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Echopulse is specially designed, manufactured and CE marked for treating breast fibroadenoma. HIFU is a completely alternative to surgery which utilizes high-energy ultrasound to deliver a large amount of sound energy to a focal point to rapidly induce tissue heating to 85-90°C.This initiates tissue coagulation followed by tissue necrosis ablating the targeted area.

In a previous european feasibility study performed at 4 sites (France and Bulgaria), 51 fibroadenomas in 42 patients were treated. The HIFU treatment was well tolerated and showed efficacy (mean volume reduction of 72.5% +/-16.7 at 12 months follow-up.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

Description

Inclusion Criteria:

  • Female patients 18 years or older with one diagnosed breast fibroadenoma.

  • Diagnosis of fibroadenoma must be based on :

    • clinical examination,
    • ultrasound image alone for patients under 35 years old. For women older than 35 years, a mammogram will be performed in addition to ultrasound. The BI-RADS (Breast Imaging, Reporting and Data System) score of this mammogram must be less than 3.
    • histologic confirmation after core needle biopsy by two independent readers (biopsy must be performed at least two weeks before therapy unless a microbiopsy has been already done less than 3 months before inclusion visit and histopathology slices are available).

  • The requirements for the distance from the skin and the following regions of the fibroadenoma are:

    • ≤ 23 mm from the posterior border of the fibroadenoma
    • ≥ 5 mm from the anterior border of the fibroadenoma
    • ≥ 11mm from the focal point of the HIFU treatment. These criteria shall be evaluated immediately prior to treatment once breast is immobilized and potentially compressed
  • The rib cage should not be in the prefocal ultrasound path or behind the target fibroadenoma (minimum distance behind the focal point= 10 mm). This criterion shall only be reached in treatment conditions, once breast is immobilized and potentially compressed.
  • Patient's fibroadenoma is 1 cm or greater at its largest dimension
  • Fibroadenoma is palpable
  • Patient has signed a written informed consent.

Exclusion Criteria:

  • Patient who is pregnant or lactating.
  • Patient with a BI-RADS score > 2 at the mammogram, or presence of microcalcifications within the lesion.
  • Patient with history of breast cancer or history
  • Patient with history of laser or radiation therapy to the target breast
  • Patient with breast implants in the target breast
  • Patient with a breast cyst
  • Patient's fibroadenoma not clearly visible on the ultrasound images (in B mode) at the inclusion visit
  • Patient participating in other trials using drugs or devices.
