About this study

Official title: Comparing the Performance of Automated Breast Ultrasonography (ABUS) to Hand-Held Breast Ultrasonography (WBUS) in Breast Cancer Treatment Response Assessment in a Tertiary Cancer Center: A Prospective Study

This study compares the performance of automated breast ultrasonography and conventional hand-held whole breast ultrasonography when checking for response to breast cancer treatment. Breast ultrasonography is operator dependent and time-intensive. Automated breast ultrasonography scanners were developed to allow standardization of ultrasound scanning and scanning to be performed by any technologist, with or without previous ultrasound experience, without physician involvement. This study may validate the use of the automated breast ultrasonography.

Read the detailed description

PRIMARY OBJECTIVE:

  1. To estimate and compare the accuracy of automated breast ultrasonography (ABUS) and hand-held whole breast ultrasonography (WBUS) in predicting pathology complete response (pCR) with relative tumor volume change, using the receiver operating characteristic (ROC) curve analysis.

SECONDARY OBJECTIVES:

  1. To evaluate the reproducibility of tumor volume measurements obtained by ABUS and handheld WBUS, respectively, using data collected at baseline for initial staging.

II. To assess the agreement in relative tumor volume change (RC) (end-of-treatment versus [vs.] pre-treatment) between ABUS and WBUS.

III. To estimate and compare the following diagnostic measures for ABUS and WBUS: sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV).

OUTLINE:

Patients undergo ABUS over 15 minutes followed by WBUS over 30 minutes at baseline, mid-treatment and pre-surgery (end of treatment).

What is being measured

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

  1. Area under the receiver operating characteristic (ROC) curve

    Will compute relative tumor volume change for both automated breast ultrasonography (ABUS) and hand-held whole breast ultrasonography (WBUS) and estimate pathology complete response ROC curves for each. Will estimate the areas under the ROC curves along with 95% confidence intervals and then compare the values statistically.

    Measured: through study completion, an average of 1 year

Secondary outcomes (6)
  1. Tumor volume

    Will compute the intraclass correlation coefficient for each method along with 95% confidence intervals and then compare these estimates.

    Measured: through study completion, an average of 1 year

  2. Relative tumor volume change

    Will compute the relative change in tumor volume for ABUS and WBUS and assess their agreement using the Bland-Altman approach.

    Measured: through study completion, an average of 1 year

  3. Sensitivity

    The cutoff point will be determined using Youden Index, i.e., the point that maximize (sensitivity specificity).

    Measured: through study completion, an average of 1 year

  4. Specificity

    The cutoff point will be determined using Youden Index, i.e., the point that maximize (sensitivity specificity).

    Measured: through study completion, an average of 1 year

  5. Positive predictive value

    Measured: through study completion, an average of 1 year

  6. Negative predictive value

    Measured: through study completion, an average of 1 year

Questions about this trial

What is this clinical trial studying?

An observational study of Breast Carcinoma, run by M.D. Anderson Cancer Center at 1 site 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 6 inclusion and 3 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: withdrawn, as of the sponsor's last update on 27 May 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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 was withdrawn before enrolling participants, so there are no results.

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?

Area under the receiver operating characteristic (ROC) curve (time frame: through study completion, an average of 1 year). 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 27 May 2022.
