About this study

Official title: Pilot Study: Dedicated Dual Head Molecular Breast Imaging Compared to Breast Tomosynthesis for Evaluation of Patients With Type 3 or 4 Mammographic Breast Density

Primary:

In women with heterogeneous or dense breast tissue (mammographic types 3 and 4), MBI (Molecular Breast Imaging) will detect more breast cancers and have greater sensitivity in detecting breast cancer than breast tomosynthesis.

Read more

Secondary:

  1. In women with heterogeneous or dense breast tissue, the specificity of MBI in correctly classifying subjects without breast cancer will be non-inferior to breast tomosynthesis.
  2. In women with heterogeneous or dense breast tissue, the area under the receiver operating characteristic (ROC) curve for MBI will be non-inferior or superior to breast tomosynthesis.
  3. Combining the use of MBI and breast tomosynthesis will provide performance superior to either technology alone, as manifest by a superior ROC curve area.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • MBI Scan: The LumaGEM®Device

    The LumaGEM Scanner is a dual-head, MBI scanner that has previously been cleared for medical marketing (510(k) number K111791), and has been used to image more than 5,000 patients to date. The LumaGEM MBI scanner is used as a diagnostic adjunct to mammography screening for problem cases The efficacy of MBI has been well documented in clinical trials. The LumaGEM MBI scanner is a dual-head, small field-of-view (FOV) device for developing an MBI image of Tc99m-Sestamibi uptake within the breast. The device consists of solid-state detectors, a data acquisition system, and a computer. The detectors are also used to immobilize the breast during image acquisition by mild compression. The detectors are housed in two heads that are positioned on both sides of a compressed breast.

  • 3D Mammogram/Breast Tomosynthesis Scan: Selenia® Dimensions®Device

    The breast tomosynthesis procedure involves x-ray imaging of the breast using a moving x-ray source and digital detectors composed of cesium iodide crystals on an amorphous silicon layer or of solely selenium in order to produce an image of the breast. This procedure is considered to basically be a modification of mammography and also is used as a diagnostic adjunct to mammography screening for problem cases.

What is being measured

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

  1. Sensitivity/Cancer detection

    Sensitivity being the number of scans read or labeled positive (by radiologist) divided by the total cancers confirmed by pathology results (i.e. biopsy).

    Measured: 12 months

Secondary outcomes (1)
  1. Specificity

    Specificity being the total number of scans read or labeled as negative (by a radiologist) divided by number of total women without cancer. This "ground truth" of a true negative will involve in a second negative imaging scan at 12 months (follow-up exam).

    Measured: 12 months

Questions about this trial

What is this clinical trial studying?

A study testing MBI Scan: The LumaGEM® and 3D Mammogram/Breast Tomosynthesis Scan: Selenia® Dimensions® in people with Breast Neoplasms, run by Gamma Medica, Inc..

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 3 inclusion and 5 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 25 Aug 2014. Status can change between updates, so confirm with the study contact before making plans.

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?

Sensitivity/Cancer detection (time frame: 12 months). 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 25 Aug 2014.
