Breast | IHC quantification | HER2

The first plug-and-play AI solution to detect and quantify HER2 within predefined RoIs of breast cancer tissue

Mindpeak Breast HER2 RoI is a software for automated image analysis of digital histopathology images of human invasive mamma carcinoma tissue samples. It is a stand-alone software module which supports the analysis of digital images acquired by scanning the fixed and HER2 stained samples of invasive ductal and lobular carcinoma without the need for manual fine-tuning it to your lab.

Conformite Europe logo
Mindpeak Breast HER2 RoI is available in the EU as a CE-IVD marked medical device. Outside the EU, Mindpeak Breast HER2 RoI is Research Use Only, not for use in diagnostic procedures.

Detailed information on Mindpeak Breast HER2 RoI

Output

Mindpeak job posting downward arrow

Image analysis consists of the detection and classification of IHC stained tumor cells within predefined regions of interest (ROI). Tumor cells are classified according to membrane staining as not-stained (Negative tumor), partially stained (Partial tumor), complete but weakly stained (Complete weak tumor), complete and strongly stained (Complete strong tumor). Tumor cells exhibiting only nuclear or cytoplasmic are counted as unspecified (Unspecific tumor).

A HER2 score is provided based on the distribution of classified tumor cells within the regions of interest according to the latest clinical practice guideline of the American Society of Clinical Oncology and the College of American Pathologists (ASCO/CAP 2018): IHC 0 or 1+ (HER2 negative), IHC 2+ (equivocal/borderline) or IHC 3+ (HER2 positive).

Workflow

Step 1: Retrieve or select an image with the immunohistochemical HER2 staining suited for diagnosis and automated
analysis.

Step 2: Select regions of interest suited for diagnosis and automated analysis.

Step 3: Mindpeak Breast HER2 RoI analyses the regions of interest and calculates the results.

Step 4: Review, adjust and correct the results of the automated analysis in an integrated interactive viewer module.

Step 5: Conclude a final diagnostic decision.

Required Software

Detection and quantification of breast cancer cells

Identification & Quantification

Mindpeak Breast HER2 RoI detects and classifies cells in to 5 classes according to their membrane positivity. One of its
great advantages is its ability to differentiate between tumorous and non-tumorous structures, improving your scoring in the tumor microenvironment.

RoI

With Mindpeak Breast HER2 RoI you can manually choose the region of your interest on the whole slide image allowing for automated HER2 quantification of specific tumor subpopulations.

Lab Independent

The reliability of Mindpeak Breast HER2 RoI is unique: it provides accurate results even in challenging contexts as it was
developed with typical lab-specific variations in mind, such as slide preparation, staining and imaging.

Easy Integration

Mindpeak Breast HER2 RoI supports a broad range of scanners and can easily be integrated into existing workflows.
