Efficacy of Digital Breast Tomosynthesis + Standard 2- Dimensional Mammography in Breast Cancer

June 1, 2022 updated by: Case Comprehensive Cancer Center

Efficacy of Digital Breast Tomosynthesis (DBT) in Addition to Standard 2- Dimensional Mammography in Evaluating Extent of Disease in Newly Diagnosed Breast Cancer Patients

The purpose of this study is to determine if a 3-dimensional mammogram (DBT) may provide additional information to evaluate the extent of disease and additional findings that would aid in staging a new breast cancer patient. This would impact surgical planning and improve patient outcomes.

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

Primary Objective:

The primary objective of the study is to measure the frequency with which DBT alters the surgical plan to mastectomy versus lumpectomy. Only positive findings, like an additional site of cancer or DCIS, will be taken into account when estimating the frequency of changes to surgical management.

Secondary objectives:

  1. To measure the frequency and nature of additional findings like atypical pathology (Atypical ductal/ lobular hyperplasia, papilloma, Lobular carcinoma in situ (LCIS) , requiring surgical intervention).
  2. To identify variables on 2D (e.g. dense breasts, architectural distortions, non calcified masses) that might predict which patients would benefit from DBT.
  3. To measure the proportion of patients undergoing additional work-up following the DBT, and the subset of these patients with benign findings (i.e. False Positives).

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

25 years to 85 years (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

Description

Inclusion Criteria:

  • New diagnosis of breast cancer
  • New diagnosis if a previous breast cancer patient with negative surgical margins
  • Patients willing to sign a written informed consent form

Exclusion Criteria:

  • High risk benign lesions as the primary pathology diagnosis

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
EXPERIMENTAL: 3-dimensional tomosynthesis mammogram
The patients assigned a Breast imaging-reporting and data system (BIRADS) 5 category at the time of diagnosis and all new diagnosed breast cancer patients, will undergo a separate 2-D plus DBT in addition to the standard 2-D mammogram
Device: 2-dimensional mammogram
This is standard of care for breast cancer diagnosis. The new breast cancer patients will be scheduled for the mammogram after diagnosis at the time of surgical appointment. The radiologist reviewing the tomosynthesis images will be separate and blinded from the radiologist who reviewed the initial 2-D mammogram.
Device: digital breast tomosynthesis (DBT)
The radiation dose from this/these procedure(s) will be no more than 0.4mSv for a bi-lateral breast tomosynthesis. The new breast cancer patients will be scheduled for the mammogram after diagnosis at the time of surgical appointment. The radiologist reviewing the tomosynthesis images will be separate and blinded from the radiologist who reviewed the initial 2-D mammogram.
Other Names:
  • 3-dimensional mammogram

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
Number of Participants for Which DBT Altered Surgical Plan
Time Frame: At completion of 3-Dimensional mammogram (1 day)
Only positive findings, like an additional site of cancer or atypical pathology like Atypical ductal/ lobular hyperplasia, papilloma, DCIS/LCIS (findings requiring surgical intervention), will be taken into account when estimating the frequency of changes to surgical management
At completion of 3-Dimensional mammogram (1 day)

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
