Study summary

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 researchers measure

Primary outcomes

  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.

    Time frame: up to 24 weeks

Secondary outcomes

  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.

    Time frame: 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.

    Time frame: up to 24 weeks
