NCT03233191

Brief Summary

This randomized phase III trial studies digital tomosynthesis mammography and digital mammography in screening patients for breast cancer. Screening for breast cancer with tomosynthesis mammography may be superior to digital mammography for breast cancer screening and may help reduce the need for additional imaging or treatment.

Outcome Measures

Primary Outcomes (1)

  • Proportion of women diagnosed with an advanced breast cancer at any time during a period of 4.5 years from randomization, including the period of active screening and a period of follow up after the last screen

    The cumulative proportions of participants experiencing the primary endpoint in the two study arms will be compared. The primary comparison of the two study arms will be approached from an Intent-to-Treat perspective and will be based on a two-sided test for comparing binomial proportions.

    4.5 years after last registration

Secondary Outcomes (17)

  • Agreement between local and expert study pathologists for all breast lesions (benign and malignant) biopsied during the five years of screening

    Up to 8 years

  • Breast Imaging-Reporting and Data System (BIRADS) imaging features

    Up to 8 years

  • Breast-cancer-specific mortality

    Up to 8 years

  • Centralized quality control (QC) monitoring program implementation

    Up to 8 years

  • Diagnostic and predictive performance of tomosynthesis mammography (TM) and digital mammography (DM) [AUC]

    Up to 8 years

  • +12 more secondary outcomes

Study Arms (2)

Arm A (digital mammography)

EXPERIMENTAL

Patients undergo bilateral screening DM with standard CC and MLO views at baseline, 12, 24, 36, and 48 months if pre-menopausal or at baseline, 24, and 48 months if post-menopausal.

Procedure: Digital MammographyOther: Laboratory Biomarker Analysis

Arm B (digital tomosynthesis mammography)

EXPERIMENTAL

Patients undergo manufacturer-defined screening TM at baseline, 12, 24, 36, and 48 months if pre-menopausal or at baseline, 24, and 48 months if post-menopausal.

Procedure: Digital Tomosynthesis MammographyOther: Laboratory Biomarker Analysis

Eligibility Criteria

Age45 Years - 74 Years
Sexfemale
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Women of childbearing potential must not be known to be pregnant or lactating
  • Patients must be scheduled for, or have intent to schedule, a screening mammogram
  • Patients must be able to tolerate digital breast tomosynthesis and full-field digital mammographic imaging required by protocol.
  • Patients must be willing and able to provide a written informed consent
  • Patients must not have symptoms or signs of benign or malignant breast disease (eg, nipple discharge, breast lump) warranting a diagnostic rather than a screening mammogram, and/or other imaging studies (eg, sonogram); patients with breast pain are eligible as long as other criteria are met
  • Patients must not have had a screening mammogram within the last 11 months prior to date of randomization
  • Patients must not have previous personal history of breast cancer including ductal carcinoma in situ
  • Patients must not have breast enhancements (e.g., implants or injections)
  • ANNUAL SCREENING REGIMEN ELIGIBILITY CHECK
  • Patients are pre-menopausal; OR
  • Post-menopausal aged 45-69 with any of the following three risks factors:
  • Dense breasts (BIRADS density categories c-heterogeneously dense or d-extremely dense), or
  • Family history of breast cancer (first degree relative with breast cancer), or, positive genetic testing for any deleterious genes that indicate an increased risk for breast cancer, or
  • Currently on hormone therapy; OR
  • Post-menopausal ages 70-74 with either of the following two risk factors:
  • +5 more criteria
