Low-dose Molecular Breast Imaging: Comparison of Breast Cancer Detection Rate at Initial Screening and Two-year Follow-up

September 19, 2016 updated by: Deborah Rhodes, Mayo Clinic

Comparison of Breast Cancer Detection Rate for Prevalent Screen Low-dose Molecular Breast Imaging and Incident Biennial Screen Low-dose Molecular Breast Imaging in Women With Mammographically Dense Breasts

The purpose of this research is to evaluate whether repeating a screening Molecular Breast Imaging (MBI) study two years after an initial screening MBI study further improves breast cancer detection in women with dense breast tissue.

Description

Inclusion Criteria:

- Past prior screening mammogram within the previous 11-24 months interpreted as heterogeneously dense or extremely dense and negative or benign [Breast Imaging Reporting and Data System (BI-RADS) Category 1 or 2]

Subjects will be excluded if they:

  • Are unable to understand and sign the consent form
  • Are pregnant or lactating
  • Are physically unable to sit upright and still for 40 minutes
  • Have self-reported signs or symptoms that may suggest breast cancer (palpable mass, bloody nipple discharge, axillary mass, etc.)
  • Have had needle biopsy within 3 months, or breast surgery or radiation within 1 year prior to the study
  • Are currently receiving chemotherapy or tamoxifen, raloxifene, or an aromatase inhibitor for adjuvant therapy or chemoprevention
  • Have undergone bilateral mastectomy
  • Have had a prior MBI within 20 months of scheduled study MBI.

Intervention / Treatment
Experimental: Molecular Breast Imaging
Molecular Breast Imaging (MBI) utilizes small high resolution gamma camera detectors in a dual-detector configuration to image the breast following the administration of a radiopharmaceutical that accumulates preferentially in breast tumors.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Molecular Breast Imaging (MBI) scan
Time Frame: Performed at Year 0 of study
The Year 0 MBI will be interpreted in isolation, with the radiologist blinded to Year 0 mammogram results and all relevant clinical information.
Performed at Year 0 of study

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Molecular Breast Imaging (MBI) scan
Time Frame: Performed at Year 2 of study
The Year 2 MBI will be interpreted in comparison with the Year 0 MBI but in isolation from the Year 2 mammogram.
Performed at Year 2 of study

Other Outcome Measures

Outcome Measure
Measure Description
Time Frame
Comparison of breast cancer detection rate for Year 0 and Year 2.
Time Frame: Year 2 of study
The breast cancer detection rate for Year 0 and Year 2 MBI will be compared to each other and to the breast cancer detection rates for the screening mammograms performed in Year 0 and Year 2.
Year 2 of study
