Comparison of Stationary Breast Tomosynthesis and 2-D Digital Mammography in Patients With Known Breast Lesions

March 19, 2018 updated by: UNC Lineberger Comprehensive Cancer Center

Comparison of Carbon Nanotube X-ray Stationary Digital Breast Tomosynthesis and 2-D Digital Mammography in Patients With Known Breast Lesions.

The goal of the study is to compare the radiologist confidence level in evaluating patients with known breast lesions using a carbon nanotube x-ray based stationary breast tomosynthesis imaging device. The comparison will be made against conventional mammography acquired as a part of a standard clinical workup. One hundred patients who are to have a clinical surgical breast biopsy will be recruited for the study. A reader study will be performed to evaluate the ROC characteristics of the system.

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Observational

Enrollment (Actual)

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

Sampling Method

Non-Probability Sample

Study Population

Patients undergoing surgical breast biopsies for lesions detected on mammograms.

Description

Inclusion Criteria:

  • Women at least 18 years old.
  • Scheduled for breast biopsy of at least one breast lesion.
  • Lesion detected on mammogram.
  • Symptomatic by patient self-report, patient self-breast exam or clinical exam.
  • Able to provide informed consent.

Exclusion Criteria:

  • Male. (It is uncommon for men to present for imaging and the overwhelming majority of findings are non-cancerous and do not lead to biopsy; male breast cancer represents <1% of newly diagnosed breast cancer)
  • Less than 18 years of age.
  • Patient unable to give consent.
  • Institutionalized subject (prisoner or nursing home patient).
  • Any woman who is pregnant or has reason to believe she is pregnant or any woman who is lactating

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
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.
Patients
Patients with a breast lesion undergoing surgical biopsy. All patients will undergo stationary Carbon Nanotube x-ray digital breast tomosynthesis imaging in addition to routine conventional digital mammography.
Device: Stationary Carbon Nanotube X-ray Digital Breast Tomosynthesis Scanner
All patients will undergo conventional imaging and imaging with the carbon nanotube based x-ray stationary digital breast tomosynthesis scanner device.
Other Names:
  • Carbon nanotube based x-ray digital breast tomosynthesis (CNT SDBT) Scanner

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Receiver Operative Curve (ROC) Area Under the Curve (AUC) (percentage)
Time Frame: approximately 18 months
Receiver Operative Curve (ROC) Area Under the Curve (AUC) analysis of the stationary breast tomosynthesis (SDBT) system for the the characterization of suspicious breast lesions in comparison to x-ray mammography.
approximately 18 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Reader preference - arbitrary units
Time Frame: approximately 18 months
To evaluate radiologists confidence in evaluating specific lesion characteristics in suspicious breast lesions. Readers will be scored from -3 to +3.
approximately 18 months

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (ACTUAL)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
