What is it? The InSite™ Her-2/neu is a kit used to identify breast cancer patients eligible for treatment with the cancer drug Herceptin® (Trastuzumab). It is used with an automated tissue staining system or manual assays and specialized staining accessories.

This test is used by a doctor trained to identify diseases by studying slices of cells and tissues placed on microscope slides (pathologist) to analyze breast cancer tissue samples. The test detects a protein in the body that stimulates cancerous tissue cell growth (Her-2/neu tyrosine kinase). The presence of this protein indicates eligibility for breast cancer treatment with the FDA approved drug Herceptin®.

How does it work? The InSite™ Her-2/neu is a kit used to identify Her-2/neu in a tissue sample.

  • A small tissue sample containing cancer is cut from the patient’s breast cancer (biopsy).
  • The tissue is embedded in a block of paraffin wax and a thin slice is cut from the block and attached to a glass slide.
  • Anti-Her-2/neu antibodies are added to the sample and incubated.
  • The InSite™ Her-2/neu kit adds chemicals that stain sites where anti- Her-2/neu antibodies have bound to the cancer.
  • The sample is analyzed by a pathologist with a microscope.
  • The presence of these reactions indicates a patient is eligible for cancer treatment with Herceptin®

When is it used? The InSite™ Her-2/neu kit is used in patients with breast cancer that are candidates for therapy with Herceptin®.

What will it accomplish? The InSite™ Her-2/neu kit determines if a breast cancer patient is eligible for treatment with Herceptin®.

When should it not be used? There are no contraindications for this device.
