About this study

Official title: The Added Value of Digital Breast Tomosynthesis Over Mammography in Local Tumor Staging in Patients With BIRADS 4 or 5 Lesions

Compare the diagnostic accuracy of tomosynthesis with 2D mammography in cases with suspected BI-RADS 4 or 5 to determine its potential benefit for staging

Read the detailed description

Digital breast tomosynthesis (DBT) is a promising 3D imaging technique for breast imaging that use in breast cancer detection. it acquires reconstructed volume data , the data is reconstructed secondarily in mammary slices from several radiographs acquired from different angles of view (-15◦ to +15◦ for Fuji). It theoretically improves the sensitivity of detection by enabling enhanced delimitation of the lesion margins, and the specificity by avoiding the problem of glandular superimposition, By separating overlapping breast tissues \& it enhances detection of abnormalities located in different planes. DBT has higher breast cancer detection rates and lower recall rates compared with digital mammography (DM). There is also evidence of the diagnostic efficacy of DBT in women with clinical symptoms and women with screen-detected findings who have been recalled for work-up. Consequently, recommendations have been made about the role of DBT in screening asymptomatic women according to their risk levels, in evaluation of symptomatic women, and in work-up of suspicious DM findings. The main objective of this study was to compare tomosynthesis with 2D mammography in cases with suspected BI-RADS 4 or 5 anomalies, to determine its potential benefit for staging.

    the type of lesion (mass , microcalcification , architectural distortion) in both tomosynthesis and mammography for the main and satellite lesions

    Measured: baseline

  3. Recording the probability of multifocality or multicentricity in both tomosynthesis and mammography for the main and satellite lesions

    the probability of multifocality or multicentricity in both tomosynthesis and mammography for the main and satellite lesions

    Measured: baseline

  4. Recording the location of the tumor within the mammary quadrants and the depth of the tumor in both tomosynthesis and mammography for the main and satellite lesions

    The location of the tumor within the mammary quadrants (upper , lower , outer , inner ) and the depth (anterior-middle-posterior) of the tumor in both tomosynthesis and mammography for the main and satellite lesions

    Measured: baseline

  5. Recording the tumor histopathology type for the main and satellite lesions

    Recording the tumor histopathology type (ductal, lobular , in situ , others) for the main and satellite lesions

    Measured: baseline

Questions about this trial

What is this clinical trial studying?

An observational study of Digital Breast Tomosynthesis, run by Assiut University.

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 2 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: opening soon, as of the sponsor's last update on 3 Mar 2025. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

What does the primary outcome measure?

Recording The breast density in both tomosynthesis and mammography for the main and satellite lesions (time frame: baseline). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06854887, which also lists 3 linked publications.

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?
