About this study

Fresh breast core biopsies suspicious for breast cancer that are usually taken during clinical breast assessments will be imaged via confocal microscopy.

The device so called HistologTM Scanner is based on confocal fluorescence and displays microscopic histology images superficial layers of fresh tissue.

After the imaging procedure the fresh breast tissue specimen will be followed according to the gold standard workflow (H\&E-stained images).

Subsequently, two pathologists will analyze the HistologTM Scanner obtained-images and H\&E-stained images for potential breast cancer structures.

A comparison of both analyses for cancer visualization will be performed to evaluate the feasibility of using confocal microscopy for breast cancer detection.

Read the detailed description

During clinical breast assessments physicians may detect diagnostic findings suspicious for breast cancer. In such situations a biopsy has to be taken to confirm the diagnosis histologically. Once informed consent will be obtained, the physician will collect a biopsy sample using the standard procedure with US- or MG-guided Biospy. Immediately prior to gold standard pathology workflow (formalin fixation), HistologTM Scanner will be used to image the fresh biopsy specimens. The HistologTM Scanner (v1.0, SamanTree Medical SA, Lausanne, Switzerland, CE marking) is based on confocal fluorescence and displays microscopic histology images of superficial layers of fresh tissue after nuclear staining with Acridine Orange (30 seconds) and rinsing in saline solution.

Finally, the specimen will be processed following the gold standard workflow (H\&E-stained images).

Two independent pathologists will assess the HistologTM Scanner- and H\&E-stained images subsequently according to the B-classification (categories B1-B5; "0" was defined as "no diagnosis possible") and determine the correspondence of the results.

What is being measured

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

  1. Correspondence of pathologic assessment in specimen suspicious for breast cancer

    Evaluate the correspondence of breast cancer diagnosis based on confocal HistologTM Scanner images in comparison with gold standard pathology assessment.

    Measured: up to 24 weeks

Secondary outcomes (2)
  1. Usability of the HistologTM Scanner confocal device

    Assess the usability of the HistologTM Scanner confocal device in the context of breast surgery by gathering feedback and expert opinion from the medical staff involved in the research study.

    Measured: up to 24 weeks

  2. Acceptance of the HistologTM Scanner confocal device

    Assess the acceptance of the HistologTM Scanner confocal device in the context of breast surgery by gathering feedback and expert opinion from the medical staff involved in the research study.

    Measured: up to 24 weeks

Questions about this trial

What is this clinical trial studying?

An observational study of Breast Cancer, run by Brust-Zentrum AG at 1 site in Switzerland.

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 4 inclusion and 6 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: finished, as of the sponsor's last update on 21 May 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Switzerland. Whether a site is taking part right now should be confirmed with that site. See every site.

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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Correspondence of pathologic assessment in specimen suspicious for breast cancer (time frame: up to 24 weeks). 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 21 May 2018.
