About this study

Official title: A Multicenter, Controlled Clinical Trial to Evaluate the Hologic 3-D Tomosynthesis Mammography System Used in Conjunction With Conventional 2-D Digital Mammography

This was a multi-center, prospective clinical trial in which the subject was her own control. Approximately 950-1400 female subjects were enrolled at five (5) sites in the United States. Subjects were from either a Screening population or a biopsy population and were imaged first on a conventional 2D full filed digital mammography system then on a 3D tomosynthesis system.

The resulting images from the this portion of the study were then randomized into a reader study.

The purpose of this clinical study was to compare the 3-D tomosynthesis system used in conjunction with a conventional 2-D digital imaging system (2-D plus 3-D images) to the conventional 2-D digital imaging system (2-D images), and to determine whether the 2-D plus 3-D images compared to the 2-D images alone would:

  1. Reduce the recall rate And/or
  2. Improve ROC area due to improved breast cancer detection and/or improved lesion classification.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Tomosynthesis digital mammography imaging systemDevice

    Also called Genesis, Hologic Tomosynthesis, Tomo

    a full-field digital mammography system where multiple images are acquired at various angles near the normal to the detector. Breast compression is performed in a standard geometry. The acquired images are reconstructed using mathematical algorithms, not unlike CT reconstructions, to generate a set of thin slices parallel to the breast platform. The reconstructed slices can be viewed individually or in a movie format.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. To detect a 20% reduction in the recall rate when comparing the recall rate using the BIRADS 0 scores of the 2-D plus 3-D images to the 2-D images.

    Measured: 10-12 months

Secondary outcomes (1)
  1. To detect a 0.05 increase in the area under the ROC curve when comparing 2-D plus 3-D images to the 2-D images.

    Measured: 10-12 months

Questions about this trial

What is this clinical trial studying?

A study testing Tomosynthesis digital mammography imaging system in people with Breast Cancer, run by Hologic, Inc. at 5 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 12 Aug 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

To detect a 20% reduction in the recall rate when comparing the recall rate using the BIRADS 0 scores of the 2-D plus 3-D images to the 2-D images. (time frame: 10-12 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Aug 2022.
